Well completions

Once an oil/gas well is being drilled and commercially viable quantities of oil/gas are present for extraction, the well must be 'completed' to allow for the flow of petroleum out of the formation and up to the surface. This process includes strengthening the well hole with casing, evaluating the pressure and temperature of the formation and installing proper equipment to ensure an efficient flow of oil/gas out of the well.

Condensate wells are wells that contain natural gas, as well as a liquid condensate. This condensate is a liquid hydrocarbon mixture that is often separated from the natural gas either at the wellhead, or during the processing of the natural gas. It is important to remember that natural gas, being lighter than air, will naturally rise to the surface of a well. Because of this, in many natural gas and condensate wells, lifting equipment and well treatment are not necessary.

Completing a well consists of a number of steps: installing the well casing, completing the well, installing the wellhead, and installing lifting equipment or treating the formation should that be required.
Installing well casing is an important part of the drilling and completion process. Well casing consists of a series of metal tubes installed in drilled hole. Casing strengthens the sides of the well hole, ensures that no oil or natural gas seeps out of the well hole as it is brought to the surface. A good deal of planning is necessary to ensure that the proper casing for each well is installed. The type of casing used depends on the subsurface characteristics of the well, including the diameter of the well and the pressures and temperatures experienced throughout the well. The diameter of the well hole depends on the size of the drill bit used. In most wells, the diameter of the well hole decreases the deeper it is drilled, leading to a type of conical shape that must be taken into account when installing casing.

There are five different types of well casing. They include:

-Conductor Casing
-Surface Casing
-Intermediate Casing
-Liner String
-Production Casing
-Conductor Casing

Conductor casing is installed first, usually prior to the arrival of the drilling rig. The hole for conductor casing is often drilled with a small auger drill, mounted on the back of a truck. Conductor casing is usually no more than 20 to 50 feet long. It is installed to prevent the top of the well from caving in and to help in the process of circulating the drilling fluid up from the bottom of the well. Onshore, this casing is usually 16 to 20 inches in diameter, while offshore casing usually measures 30 to 42 inches. The conductor casing is cemented into place before drilling begins.

Surface casing is the next type of casing to be installed. It can be anywhere from a few hundred to 2,000 feet long, and is smaller in diameter than the conductor casing. When installed, the surface casing fits inside the top of the conductor casing. The primary purpose of surface casing is to protect fresh water deposits near the surface of the well from being contaminated by leaking hydrocarbons or salt water from deeper underground. It also serves as a conduit for drilling mud returning to the surface, and helps protect the drill hole from being damaged during drilling. Surface casing, like conductor casing, is cemented into place.

Intermediate casing is usually the longest section of casing found in a well. The primary purpose of intermediate casing is to minimize the hazards that come along with subsurface formations that may affect the well. These include abnormal underground pressure zones, underground shale, and formations that might otherwise contaminate the well, such as underground salt-water deposits. In many instances, even though there may be no evidence of an unusual underground formation, intermediate casing is run as insurance against the possibility of such a formation affecting the well.

Liner strings are sometimes used instead of intermediate casing. Liner strings are commonly run from the bottom of another type of casing to the open well area. However, liner strings are usually attached to the previous casing with 'hangers', instead of being cemented into place.

Production casing, alternatively called the 'oil string' or 'long string,’ is installed last and is the deepest section of casing in a well. This is the casing that provides a conduit from the surface of the well to the petroleum-producing formation. The size of the production casing depends on a number of considerations, including the lifting equipment to be used, the number of completions required, and the possibility of deepening the well at a later time.

Installing Well Casing

Well casing is a very important part of the completed well. In addition to strengthening the well hole, it provides a conduit to allow hydrocarbons to be extracted without intermingling with other fluids and formations found underground. It is also instrumental in preventing blowouts, allowing the formation to be 'sealed' from the top should dangerous pressure levels be reached.

Well completion commonly refers to the process of finishing a well so that it is ready to produce oil or natural gas. In essence, completion consists of deciding on the characteristics of the intake portion of the well in the targeted hydrocarbon formation. There are a number of types of completions, including:

Open Hole Completion
Conventional Perforated Completion
Sand Exclusion Completion
Permanent Completion
Multiple Zone Completion
Drainhole Completion


Well Head


It is the philosophy that during the drilling, - testing, completion water injection and workover of an oil or gas well, any work undertaken should be executed in such a manner that:

1. Loss of human life and injury to crewmembers shall be avoided

2. Pollution of the surrounding environment shall be avoided

3. Loss of rig and damage to equipment shall be avoided.

If all of the aforementioned conditions are fulfilled then the economic and ecological result shall be successful. It is also the philosophy :

1. That detection and controlling a kick takes a team effort from all members of the rig crew. Each member must be completely familiar with his duties so that any well control operation can proceed smoothly and efficiently

2. To maintain all well control equipment in first class condition and ready for use whenever required

3. To ensure that all personnel directly involved in well control situation shall be educated to a standard that ensures complete understanding of any situation that may arise.

However, for any other Well Control procedures and guidelines to take precedence over the ones shown in the ”Well Control Manual”, the following is a must and can not be deviated:

1. At least two tested Safety Barriers shall be present in drilling and producing wells. If for some reason only one Safety Barrier is present, all activities shall cease until two Safety Barriers are reestablished

2. All Safety Barriers must be tested in accordance with approved procedures, or as specified in the programme prepared for the specific operation

3. Activity Typical Independent Barriers:

• Drilling: A sufficient amount of mud or fluid of adequate density to control the well bore pressure; certified and tested BOP stack dressed with suitable rams; unperforated, cemented and pressure tested casing or liner; tested downhole plug; back pressure valve (BPV)

• Casing: A sufficient amount of mud or fluid of adequate density to control the well bore pressure; certified and tested BOP stack dressed with suitable Casing rams

• Snubbing: BOP stack; back pressure valve in the work string; independent safety shear seal immediately on top of Christmas tree; wireline set plug

• Production: Christmas tree; surface controlled subsurface safety valve (SCSSV); downhole plug

• Wireline: Christmas tree valves; wireline BOP; wireline lubricator.

For Jack-Ups Operating under the API Standard

Frequency :  -  All blow out prevention components that may be exposed to well pressure shall be function and pressure tested as follows:

1. When installed

2. After casing has been run, cemented and BOP nippled-up; but prior to drilling out of the shoe

3. Prior to production testing or completion

4. At any time the integrity of the BOP and casing becomes suspect

5. Function test BOP with low manifold pressure, flush kill - and choke lines each week, unless well operations prevent testing

6. Or at least every 21 days (API RP 53 Third Edition section 17.3.3), unless well operations prevent testing. Well operations that may prevent testing are stuck pipe and kick control. If a period greater than 21 days has elapsed since the previous test the reason for the test postponement must be entered on the drilling report.

Offshore drilling operations - better understanding

Drilling offshore for the 'black gold" or oil in the deepwater is one of the greatest technological breakthroughs in recent decades, and many new techniques have been developed to profit from the abundance of oil underneath the seabed. While offshore shallow water drilling has been around for hundreds of years in one form or the another, the effective extraction of petroleum from beneath the sea floor did not surface until the last forty years and more recent deepwater areas are high on the look out.. The search for oil often turns out to be unproductive, but this practice is vital for the economic future of many nations, some countries drilled for their own domestic consumption and some for export.

In order for any drilling to take place, an offshore drilling rig, ship or semi-submersible must first be deployed. These offshore vessels or MODU ( mobile offshore drilling units ) can be situated in water up to a several hundred meters to thousand meters in water depth. But before any drilling takes place, an oil and gas "trap" must first be located in the ocean, and with the ocean floor being at such great depths, the visibility is often very poor. To locate potential traps, engineers use seismic surveying, and then analyze the data they receive to decide whether or not drilling in the area would have the chance of containing oil and/or gas. The engineers will not know whether their assumptions are true until they penetrate the trap with a drill bit. Due to the fact that the traps can sometimes be a great distance below the ocean, advanced computer technology is required to guide the drill bit to a fixed location. Installed above the drill bit is a navigation device, which sends back information to the controller, also known as logging the well,  allowing them to locate the exact location that is presumed to have the oil and to measure and monitor the trap. Inside the drill pipe, there is a steerable motor that can be controlled to adjust the drill and the direction in which it is headed.



Drilling Opn



Latest MODU designs are to make offshore drilling rigs and vessels much safer to operate in view of the recent accident and spill at the Gulf of Mexico while drilling and BP corporate image has somewhat suffered some setback. Offshore watchdogs, like USCG, etc, are now going to get tougher on violators and some redefining of offshore operation rules are looked at.

To make offshore drilling a little safer, extensive training would be mandatory for all of the worker on the rigs and platforms, which would reduce the number of spills due to human mistake or equipment faliure to operate under emergency situation. Furthermore, the technology in offshore drilling would need to be improved further, with new tools created that would eliminate the amount of pollutants released.

Marine biologists and researchers could perform a detailed study of the marine life in the surrounding area and attempt to design a rig that would be safer to the marine ecosystem and that could also be utilized by the marine life around the proposed area(s). Then they could use this new knowledge to make the existing rigs and platforms more eco-friendly.

Inspections of the rigs and platforms should continue, but the oil drilling companies should not be notified when the inspections will take place.


- The possibility of further pollution still exists

- The possibility of more offshore rigs being used is increased

- Oil companies would need to clean up their rigs and platforms to pass the inspections

- Some countries would no longer need to import oil, causing the supplying countries to lose money The right for the marine life to live a healthy and safe life still remains at risk

- Environmentalists worries would be put at ease (to an extent) knowing the rigs are safer Oil companies wouldn’t have to worry about being questioned for their actions



Rig Functions

What if someone in your workplace is BSing ?

For most of us, the fact that a statement is false might constitutes in itself a reason, however weak and easily overridden, not to make the statement. ... people are guided by their beliefs concerning the way things are when either in lying or telling the truth. It guide them as they have tendency to describe to the society correctly or to describe it untruly or half-truth. For such case, making out half-truths might not tend to unfit an individual for telling the truth in the same way that bullshitting tends to. Through extensive indulgence in the latter activity, which involves making assertions without paying attention to anything except what it suits one to say, a person's normal habit of attending to things may become attenuated or lost. Someone who give half-truths and someone who tells the full truth are playing on opposite sides, so to speak, in the same game. Each responds to the facts as he understands them, although the response of the one is guided by the authority of the truth, while the response of the other defies that authority and refuses to meet its demands. The bullshitter ignores these demands altogether. By virtue of this, bullshit is a greater enemy of the truth than lies or half-truth are.




  • Determine what serves the presenter’s self-interest. Whenever someone is presenting a point of view, you owe it to yourself to consider how their opinion might correlate to their own self-interest. After all, there must be some reason they have to make the argument to you in the first place. And that reason more likely correlates with their own self-interest than with yours.
  • Question the info or data. We live in a world of pseudo science, skewed sample sets and anonymous experts. Don’t accept anything as an important truth without first examining the source.
  • Look out for truth qualifying statements. “To tell you the truth” or “Let’s be frank” or “I have to be honest…” are all statements that beg the question – “Are we starting to be honest just now?”
  • Hear for name dropping. Credibility should always be derived from the strength of the argument, known facts and/or the reputation of the person present. If absent prominent people are the backbone of an argument, you should be suspect.
  • Identify confusion in response to logical counterpoints. This type of response is meant to undermine your confidence in the soundness of your counter argument without seeking to specifically or factually oppose the point itself. Watch out for confusion when there should be none.
  • Be careful of the obvious. If a conversation provides you with one obvious thought after another, wait for the end of the train of thoughts as it is typically an illogical conclusion. After getting into a “yes…yes… yes…” rhythm, you may easily accept a well placed random conclusion or mistruth.

When staff in organization started to show signs of not being truthful and behaving in the opposite, it will end up costing the company due to some of the related impact due to personnel being not giving the correct reporting and trying to cover up in fear of being reprimand should their mistake is uncovered, some of the greater impact could lead to following broader senses :-

- Persistent and disruptive strategy changes without correct stakeholders information.
- Constant debate over issues with no real feedback lacking action plan.
- Plans are agreed but some groups follow them while others hide away due to cover ups.
- Product shortfalls due to inaccurate and unreliable reporting.
- Miscommunication between management levels, i.e. middle managers are constantly "BS" by incorrect information, plans, datas.
- Consistent budget misses in either direction due to inconsistent reporting
- Support organizations like planning or production cannot cope with changing demands from technical.

Ways to Know When Someone’s BSing You
  1. Story or context changes. You can ask them the same thing two or three times and get different answers or replies.
  2. They look or pretend dumb but they’re not. It’s disingenuous, not a good sign.
  3. They put up a smart look but they’re not. Not necessarily disingenuous, but also not a good sign.
  4. They try overly hard. That’s got to give you pause.
  5. They look nervous when they shouldn’t be.
  6. They look scared when they shouldn’t be.
  7. They ask the question repeatedly. Give them time to think of an appropriate answer.
  8. There’s something in it for them. Anytime somebody’s trying to sell you something, there’s a good chance you’re being BS.
  9. They’re fanatical. Fanaticism, fundamentalism, call it whatever you want, it’s a one-sided view of an issue that cuts off debate. 
It is seen to be quite obvious - pundits, politicians, senior/junior executives, engineers, technicians, labourers, and even journalists - have sunk into habits of "BSing" from which many of them could be rescued. Many who claim to speak from faith have so cherrypicked their scripture sources that their announcements are nothing but bullshit. I do believe that most people whose characters haven't been metastasized by the greed of fame and publicity hold firmly to the conviction that "bsing" is no better than lying. What they are going to have to learn, if the society or organization is to be saved is that hearing what you want to hear and filtering out the rest which may be part of the BS.

Learn from the Big Apple !


The Big Apple, ( one that produces IPhone, Ipad, Ipod and I am not referring just the ordinary fruits perse ) has been in recent years move to being one of the best company having achieved a truly successfull innovative story, and it took only just less than a year for the Apple team to innovate from start to finish the Ipod which back then almost kill the CD industry, not instantly but almost!

Clearly, there are some lessons for innovators, maybe not just innovators but people like us in the offshore rig building industry to take a refreshing look again and where we need to re-learn our existing engineering, production & construction processes with some innovative ideas perhaps and where we could still could maintain the league in the offshore industry. We all are fully aware there are others also capable in their effort to produce rigs of demand and it will not be just the world class builder leading alone in such race for the many available offshore contracts. We need to start looking up and rebuild our strength :

Learn from past mistakes and eat the humble pie

Apple was most decidedly not thinking about portable music as the 20th century drew to a close. In the age of mp3 and peer-to-peer sharing of music, Apple was focused on video and developing iTV and iMovie - so much so, that their then current version of the iMac didn't have a CD-burner.
In fact, if they are honest, they mistook the market for music completely. The world's most innovative company was literally blind to one of the biggest social trends that was occurring at the time!

To their credit, however, and with the aid of distressing financial figures resulting from such a misreading of the market, Apple realised that it had to change its approach to the market and to the technology. Given Apple's widespread reputation for innovation and trendiness, its failure to anticipate the importance of music in the lives of personal computer users was completely uncharacteristic.
Occasioned by a US$195 million quarterly loss, however, Apple took motivation from their mistake and realised that they needed to completely rethink the way they went to market. Apple not only learned from their mistake, they used it to catapult a new innovation.

Hire those with experience and skill

So, if you're Apple, how do you recover? The common advice from most management books on building teams has typically been to: 'hire for attitude, train for skills'. This model better ensures harmonious work environments and friendly collaborations. Yet, in the world of innovation, aspirations and attitude aren't enough. In the situation that it found itself in, Apple needed real skills, and so when Steve Jobs compiled the iPod team he loaded the odds in his favour by going with his very best people in hardware, software, and design. A team was assembled because they were the best.
And putting the best skilled on a mission to change the world, drove competition within them, leading the team to perform at peak levels - nobody on that team wanted to be 'second-best'!  


Find great and workable ideas

What really sets the iPod apart from all of the other mp3 players, however, is neither the hardware, the software, nor the design - although all are world-class. The iPod's real differentiator is the ease with which the customer can access, download, store and upload the music and podcasts.
No one else can do this, and this 'innovation' did not come from within Apple, but from an outsider - Tony Fadell - who was trying to do this on his own. Apple found him - think about how difficult that is, to find someone with a good idea outside of your firm - and hired him on an eight-week contract! This was not about building a long-term employment relationship, nor about loyalty, but about accessing someone else's good idea.

Create and encourage "think" lessons

Once the team was pulled together, Steve Jobs put them into a common physical space that although not consistent with their hierarchical position, raised the probability of their having effective and fast conversations. The design team's working quarters have been described as having 'very little personal space' - there were no cubicles or offices.
By imposing open environments, the creativity and free-flow of ideas were nourished. In the flow of ideas, space matters!

Define leaderships

When you talk about Apple, you can never avoid mentioning Steve Jobs. To do so would be to underestimate his importance to the attitude of the company, and ultimately the brand.
So what role did he play in the iPod? After developing a top-notch team, Jobs gave them ambitious and clear visions. He charged the team with creating a product that would put 1,000 songs in their pocket; software so easy that their mothers could use it; and a complete product offering that would be in retail outlets in eight months.

What is so exquisite about these objectives is that they are simple, clear and precise, yet broad enough so that the team could get to work without feeling constrained by the way the vision was presented - the team could be totally focused and liberated at the same time! Innovative leaders must provide a clear briefing that organises a team but which, at the same time, doesn't restrict their talent capabilities.
Even with a reputation for getting involved in projects, Jobs actually didn't interfere all that much with the iPod project. He was both smart enough to compose a highly skilled team and then to let their skills shine. Yet, along the way, Jobs acted as both a policeman and cheerleader for the project.
He imposed an attitude that let the team members know that Apple's win would also be their personally. And, by cheerleading, he was also able to police the parameters of the project, ensuring the team stuck to his briefing goals.

Stand firm
Another Apple product, the iPhone, is now redefining the mobile phone. Yet, this innovation recently posed a threat to Apple when a technical glitch created reception problems for users. Job's response was to display true leadership by giving a message that matched what the Apple culture really is - an engineering company that has repeatedly changed the world for the better.
His message to the public was: 'We'll fix the small iPhone problem,' and to his competitors, 'catch us if you can!'   I think we as offshore rig designer and builder, probably will have to do more than Apple does and we surely have lots of technical issues to look at and we could finish sorting out, other competitors will be slowly catching up with us in no lesser time.

How having an MBA work out for you ?

Why Taiwan famous baker desperately needs to attend an eMBA ?  May 2013 news


Wu Pao-chun is an award-winning baker, a master of the breaded arts, hailed as the "glory of Taiwan" alongside Oscar-winning movie director Lee Ang.
He is an award-winning baker, a master of the breaded arts, hailed as the "glory of Taiwan" alongside Oscar-winning movie director Lee Ang. But that is not enough for Taiwanese universities, which have rejected Wu Pao-chun's attempts to get a master's degree, driving him to try his luck in Singapore.
It was at the prestigious Bakery World Cup in Paris in 2010 where Wu, now 43, became a national icon. He beat 23 rivals from 16 countries to clinch the title of Master Baker in the bread category with his rose-lychee bread creation that includes millet wine, rose petals and dried lychees - ingredients that came from Taiwan.

"I fulfilled my dream. I was able to brighten the name Taiwan," he said then.

His Wu Pao-chun Bread bakery, which opened in Kaohsiung in late 2010 to much fanfare, reportedly racked up sales of more than NT$200 million (US$6.68 million) last year. The pineapple tarts he sells are named after his mother, the late Madam Chen Wu-hsien. The youngest of eight children, he was raised by the widow in the southern county of Pingtung.
He quit school after junior high - the equivalent of secondary school in Singapore - to become a baking apprentice in Taipei, as he could not bear to see his mother slog to make ends meet. But, despite his culinary and business achievements, he was turned down in his applications to the Executive Master of Business Administration (EMBA) programme at the National Chengchi University and National Sun Yat-sen University.

EATING bak kut teh and other Singapore favourites would be great, but what celebrity baker Wu Pao-chun really hungers for when he begins an executive MBA course in the country is the know-how to run his burgeoning business, he tells The Straits Times.

Mr Wu's plan to study at the National University of Singapore (NUS) in July has caused something of a nationalistic uproar in Taiwan. But he believes it is time to venture out of his comfort zone of bread-making and school himself in finance, logistics and the management skills befitting an entrepreneur.

Mr Wu announced on the Facebook page of his shop, Wu Pao-chun Bakery, that he had accepted an offer from NUS to enrol in its Asia- Pacific Executive MBA course. For the next two years, he will attend 10 days of intensive lessons every three months. The programme is conducted in Mandarin and features field trips to countries in the region.

"I'd asked many Taiwanese friends about the programme and they told me it would give me many opportunities to learn," he said of his choice of NUS.

Mr Wu shot to fame after winning the Master Baker title in the bread category of the prestigious Louis Lesaffre Cup in France in 2010. His three-year-old shop in Kaohsiung racked up sales of more than NT$200 million (S$8.4 million) last year. His second shop, in Taipei, is due to open in August.

The high-school dropout also expressed his frustration with Taiwanese universities' graduates- only entry criteria for their EMBA programmes. Many Taiwanese, including President Ma Ying- jeou, have called for the laws to be revised. The education authorities promptly did so. The revision has been nicknamed the "Wu Pao-chun clause".

Mr Wu said yesterday that he never expected his comments to stir so much controversy. He talked enthusiastically about his upcoming stint as a lecturer at National Taiwan University, where he will teach the finer points of farming and, of course, baking. He will also attend selected business management classes at the school, on top of his studies at NUS.

Some companies would naturally love their underpaid employees.  They would bank on your guilt and sense of obligation to keep you from leaving.  Some older gen workers would rather not quit a company that has underpaid and under-appreciated them for years.  If you think or suddenly gotten up from bed and woke up realising all these years you’re not being treated right or mistreated properly, you may have to leave for better treatment or what they say commonly, "greener pasture"...... if there is such these days of poor economy led by the downfall of big economies..

Did your company pay any part of your MBA or MSc study?  If so, how long do you have to work for them without having to repay the cost of tuition? Usually you are bonded for two to three years and of course the company do not expect you to leave the company after that.  However, on the other hand, it would be unfair to let yourself be held hostage at a meager monthly sum and $100,000 less per year than another company would pay you because of a $20,000 repayment required should you decide to call it a day.  If the company did not pay  part of your tuition, then I think you don’t have to consider that in your decision calculus.   There are more reasons than salary to stay at a job.  For one, in this economy, any job is a blessing and there are people who would love to take your place.  Work-life balance is another huge one.  Sure, you can make more money somewhere else, but are they going to let you work one day a week from home?  Sometimes location really gets you–if you live in a less populated area, switching jobs can mean moving, and you don’t want to uproot everything for a strange new work place and town.

But then, you decided you want to stay.  You just want to be recognized for your skills and experience.  Let's think about what should you be thinking then :
  1. What is it that you can and couldn’t do before your MBA?  Note that I said “do” not “know.”  You may know a ton more, but does that translate into things that are helping your company?  For instance, you may have studied complex international finance policies in school, but if your company deals with nothing more international than ordering Mexican food for lunch, it’s not helpful to them.
  2. Why would they list a vacancy at a higher salary then you are making?  How in the heck should you know?  Well, if you think you need to know, Go ask.  Ask straight out what it is that you are not doing that they expected someone in this position to do.  Expect some sputtering.  It may well be a case of stupid policy, such as not giving an existing employee more than a 10% increase.
  3. Are you prepare to make more money elsewhere? We all are sure we’re fabulous and all that, but could you really make more elsewhere?  Say you only have 2 years of technical experience plus the MBA.  The market is flooded now in the marine and offshore sector, so they may well be paying you precisely what you’re worth to them.  It’s not the job of a company to pay you what you need to live your chosen lifestyle.  It’s their job to pay you in accordance with the amount you can help the organisation or section. And remember in big organization, no one is indispensable no matter how high or senior you are in the company.
  4. Do you need to asked directly for a raise? You say you got a fabulous retention bonus, EVA, extras,etc.   Your bosses may think, “Gee, weren’t we generous with that retention bonus?” and have no plans to give you a raise.  They may not know that you think you deserve one.  After all, they may feel like they’ve adequately compensated you for your increased skills.  You need to spell it out for them.
  5. Do you need to show that you are more valuable. Make a list of all the functions you do, along with a description of how you do them.  If you have the chance to write a self-appraisal, now is the time to do so.  If you need to, try to make it obvious that you are underpaid.  Make it extremely obvious that you are technically experience and well informed on the technological arena.  This is not the time to be modest.  Save that for dinner with your in-laws.
  6. If you need to be moving on. It’s a sad truth, but sometimes companies just won’t ever appreciate you or realise how you have contributed to the organisation until someone else wants to buy you out.  But, if you’ve talked repeatedly about your undying devotion, or how you can never leave because you live across the street, they just won’t see any reason to increase your salary.
Personally, the three letters MBA on your resume are not going to make you automatically more valuable. I have my MBA and believe that without a doubt it has helped me to grow into the position I have today. I am also very fortunate to have given another Master course to pursue after my p/t MBA and this really given me another overview of the marine technology where everyday I am still in the learning process. I would not have achieved what I have without the skills I've learned along the way. An MBA rounds out a person's skills to help bring "the big picture" into perspective. In time, the rewards will come from the value you'll bring to a team....not three letters behind your name.

P.S. Never try to go to your employer with an offer from another company. That would be your biggest mistake if you somehow foolishly err on this move. Even if some company try to buy you out, you've planted the seeds of disloyalty with your present one and you'll ruin your career in the long run or at least make a bad name in your record. Instead, try approach with why you feel you deserve more but do not try to be hardup. If they choose not to pay you what you feel you're worth, then you can actively seek other options with a clear conscious.

Having an MBA is a sign of potential, not performance, so the key question is to identify how performance has changed as a result of the MBA. One reason I find p/t MBAs - where students continue to work while doing their studies - much more successful (for both the student and the company) than f/t MBAs is that the student has many opportunities during the program to discuss their learning with their peers and bosses and put new ideas into real practical practice. They can put markers down about their improved performance as they go along. This makes it much easier to negotiate job changes and pay rises after the studies have been completed.
