Well Control Formulas Archives – Drilling Formulas and Drilling Calculations
Understanding this concept is very beneficial when you start studying the practice questions. I cannot emphasize this enough, you really do learn about the equipment by studying the questions and it all starts to make sense after a while. The mud pump is slowly brought up to kill rate speed in 5 SPM intervals while the Level 4 supervisor slowly opens the choke to maintain the original casing pressure.
All you need to do is plug the numbers in and calculate forumla mud weight needed to kill the well. C is calculated by plugging A and B into the formula given to you in the box.
IWCF Drilling Calculation Part 1 – 3 Review
Mud Increment MI — It is volume of mud bled off from the annulus to reduce hydrostatic pressure by amount frmula Pressure Increment. Subscribe to our mailing list and get interesting stuff and updates to your email inbox. Hello, Could you tell me on which iwcf test version are your questions based?
Eduardo 1 year ago. Fabrizio 1 year shewt. The most effective way I found to do this was to hit the material in small minutes blocks a few times each day.
Trey Pace 2 years ago. It should not be ? April 22, at Above all thank you.

How to Pass the IWCF Supervisor Well Control Exam – The Maritime Site
This guide does not replace the requirement to attend a certified well control school, iwccf, it is designed to supplement the training received in the gormula and to ensure the IWCF candidate is as prepared as possible PRIOR to attending the IWCF class.
You must round down to Total active fluid system volume is calculated by adding the previous two volumes and strokes together. 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.
Try solving as many problems as you can without referring to the formula sheet. It is also the longest. 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: If you detect that your choke is plugging, you should immediately shut down the mud pump.
I have a well control question. Remember you always round up Kill Mud Weight to the nearest tenth and you always round down your Maximum Allowable Mud Weight to the nearest tenth.
Domingues Basilio 2 years ago. Your email address will not be published. Ben Dinsmore 2 years ago. Remember, formation pressure is the actual pressure of the formation you are drilling into. Not only did I not know much about lining up a choke manifold or standpipe manifold, I knew virtually nothing about what RPM to drill at, how much pressure to maintain on the drillpipe or SPM on the mud pumpshow much weight to maintain on the drill bit while drilling, etc.
The next part is about the circulating system on the rig. The displacement per stroke of the pump is given shet you as well as the slow pump rate data through the riser and the choke line. August 14, at This is especially true for students pursuing Level 3 or Level 4 certification as it adds a graded practical exam simulator exercise to the mix. 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.

The third part will cover various concepts of well control so learner must have good basic calculation background. Once the washed out choke is isolated, you need to quickly shwet down the pump to avoid adding too much bottom hole pressure from pumping against a closed choke.
This site uses Akismet to reduce spam. I had probably 10 of formjla problems on my IWCF Level 4 exam and they made up a very large percentage of my final score.
Bottom hole pressure is the pressure at the fornula of the well that is created by the hydrostatic weight of the mud in the well plus formhla additional forces created by annular friction from circulating mud through the well.
Another area where you can score huge points on the IWCF exam is on the gauge problems. If you are interested in these excellent well control handouts, please check out the following links to download them. Your Tsegai petroleum engineer with 2 years experience.
