For example, you would use MD when calculating the volume of fluid in the drill pipe but you would use TVD when calculating the hydrostatic pressure of the fluid in the drill pipe.

I loved it and wish to get or to be sent these documents through my email. The additional psi on the casing gauge is the additional pressure needed to keep the U-Tube balanced between the casing side and the drill pipe pressure side.

How to Pass the IWCF Supervisor Well Control Exam

Another area where you can score huge points on the IWCF exam is on the gauge problems. This is the pressure you expect to see on the drill pipe pressure gauge when first starting to circulate out the kick. iwcc

Personnel must select small safety factor to prevent fracturing formation. Safety Factor SF — The Safety Factor SF in an increase in bottom hole pressure which we allow seet happen naturally when gas influx migrates up with the shut in well.

It will be expected that you slowly stop the mud pump gradually slowing the pump maintaining casing and kill-line pressure. However, before you get started I want you to check your equipment and make sure you have everything set up the way it needs to be. Example Kill Sheet Problems with Explanations: This guide does not replace the requirement to attend a certified well control school, instead, it is designed to supplement the training received in the classroom and to ensure the IWCF candidate is as prepared as possible PRIOR to attending the IWCF class.

Calculating the drill string volume is as simple as plugging the length of your drill pipe, heavy weight drill pipe hevi wall or HWDP and drill collar into the drill string volume section.

Measured depth is used when calculating volumes of fluids. Total shoe minus riser? This loss of hydrostatic pressure is compensated by the increase in casing pressure. Space out for well control — VDO Space out means that you locate your drill string at the proper location where all the BOP rams annular and pipe rams will not close against a tool Isam Ahmed Shibani 4 years ago. Detecting a tripped mud pump is probably the easiest problem to detect during an IWCF well control simulator exam.

Your Tsegai petroleum engineer with 2 years experience. This section is where you calculate the pressure drop per every strokes of the mud pump as you start pumping heavier kill weight mud down the hole. The active surface volume is given to you in the data sheet so you record it in this section and then divide it by the pump displacement. Com Working in the oil field and loving to share knowledge. It will be tremendously helpful! After a while, there will be many questions that will become easier than others.

In almost every IWCF well control situation, the casing gauge reads higher than the drill pipe pressure.

For formila volume calculation part, you will learn how to define volume and capacity, how to calculate volumes of various shapes and the application on the rig. Firstly, the IWCF test is no joke.

C is calculated by plugging A and B into the formula given to you in the box. Additionally, IWCF provides the files in several units.

Some tricky well control questions 8. A great resource that helped me was a YouTube video produced by the Arabian Drilling Company that walks you step-by-step through the IWCF well control drilling simulation process: For example, the simulator equipment above is typical of what you might find at a common well control school. I really like Drillingformulas and when i see them e-mail on my e-mail i fell really there is some thing i need to know about it even if i know about it but there is some thing new and they cove up most of the oil wells drilling information and the work over too but i havent seen that much information about the oil wells fishing operations i realy would like to see that toothank you.

After a while, you can white out the labels on the equipment and test yourself to see if you can make it all the way through the equipment drawings without referring to an un-whited out version. These are the table of content from this book. SF is important because it will allow the bottom hole pressure to be over formation pressure so the well is not in underbalance condition while conducting later steps.

You can see where I had the driller isolate the choke and we lined up on choke 2 to resume the scenario. In the left hand column start at 0 and increase in stroke increments until you get to the total number of strokes needed to displace the drill string in our example.

August 14, at This is the pressure you expect to see on the drill pipe gauge once all of the kill mud is pumped down the drill string and is starting to enter the annulus.
