### IWCF Drilling Calculation Part 1 – 3 Review – Drilling Formulas and Drilling Calculations

This site uses Akismet to reduce spam. Mud Increment is determined by the following equation: Section 1 Whole Numbers Section 2 Estimating and Rounding Section 3 Basic mathematical calculations and the use of the calculator Section 4 Fractions, decimals, percentages and ratios Section 5 Units of measurement Section 6 Mathematical symbols, equations and arithmetical operations Section 7 Introduction to solving equations and the use of formulae Section 8 Converting formupa conversion tables.

Good morning, on which iwcf version are your questions based? SF is important because it will allow the bottom hole pressure to be over formation pressure so iwf well is not in underbalance condition while conducting later steps. 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:.

This was the scenario I was given during my practical exam. On the front of the card, I drew little gauges with pressure readings with a brief description that represented the tell tales of each possible problem that the simulator instructor could throw at me.

## Formulae Sheets

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. Since the length of Heavy Weight Drill Pipe and Drill Collars sneet given to you, all you need to do is subtract these two values from the total MD of the well to find the drill pipe length.

Minutes to End: It will be expected that you slowly stop the mud pump gradually slowing the pump maintaining casing and kill-line pressure. Ben Dinsmore 1 year ago. It is also the longest. March 21, at 4: After a while, there will be many questions lwcf will become easier than others. After you find the total drill string volume bbls in our example you divide the bbls by the pump displacement per stroke. The reason being if you made it Kill mud weight is calculated by plugging the numbers into the formula provided in the section.

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.

If the initial shut in casing pressure is very close to maximum allowable surface pressure. The final iwc of the simulator exam is learning to properly operate the choke to circulate out the influx while maintaining bottom hole pressure. The 15 feet of difference is because the marine riser is 15 feet shorter than the length of the choke line.

I had probably 10 of these problems on my IWCF Level 4 exam and they hseet up a very large percentage of my final score. Once the pump is shut down you can line up on choke 2 backup choke and resume the kill. If you encounter a plugged bit, take note of the pump pressures.

Uche uduhiri 3 years ago. Active surface volume bbls Drill pipe closed end displacement 0. The rest of the simulation was simply adjusting the choke to account for the expansion of the gas from the well.

## How to Pass the IWCF Supervisor Well Control Exam

Remember, the more you prepare, the less stressful the examination process will be! I tried to pass the exam on september and IWCF provided a brand new version.

There are a total of 5 steps as listed below. Try solving as many problems as you can without referring to the formula sheet.

The well kicked at ft vertical depth Shut in drill pipe pressure psi Shut in casing pressure psi Pit gain 10 bbl Mud Density Dealing with a Plugged Choke: Detecting a Tripped Mud Pump: Fortunately, as the week went on I got better and better.

There is also the answer section which you need to use to check the formulw.

Space formuula 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 Because you have a known column of fluid in the drill pipe you can figure out the formation pressure by simply adding the drill pipe reading to the hydrostatic sheef of the drilling mud in the drill pipe. August 16, at 1: Slow pump rate data: Your email address sehet not be published.

To find the length of DP and HWDP in the uncased section of the well the open hole section you need to first find out how much open hole you have. Section 1 Hydrostatic pressure Section 2 Primary well control Section 3 The Circulating System Section 4 Introduction to sheeg control kick prevention and detection Section 5 Secondary well control — An introduction to kill methods. There are a total of 8 modules as follows: Not only will this prevent you from burning out, but it will also allow time for the material to sink in so you can build on it during the next study section.
