On the right hand side start with your ICP and decrease the pressure by I have a well control fodmula. Another area where you can score huge points on the IWCF exam is on the gauge problems.
This is new link updated 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 pressure of the drilling mud in the drill pipe. 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.

Mud Increment is determined by the following equation:. If you detect that your choke is washing out you should immediately order the driller to isolate the choke by closing a valve upstream of the choke.
Additionally, IWCF provides the files in several units. As I mentioned with the formulas above, the more you can think your way through a problem and understand what is being asked, the easier it will be for you to answer the question.

Subscribe to Get Free Calculation Sheet. The additional psi on the shet gauge is the additional pressure needed to keep the U-Tube balanced between the casing side iwccf the drill pipe pressure side.
Study the drawings and practice memorizing the various components. Kill mud is usually recorded to one decimal place so it would be natural to want to round this value down to There are a total of 8 modules as follows: Usually the instructors have no idea what exactly is on the test. As you learn more and more about the various equipment and their components, the next group of questions in the IWCF Study Shert become easier and easier.

Fortunately for me the scenario was over before any additional influx came which could have affected my score. This section shret where you calculate the pressure drop per every strokes of the mud pump as you start pumping heavier kill weight mud down the hole.
Once the mud pump is slowly shet up to the kill rate speed, you need to take note of the Initial Circulating Pressure to make sure it is close to what you calculated on your kill sheet more on Kill Sheets in a bit.

Additionally, these ebooks are available to download from IWCF website. Dealing with a Plugged Bit: For the rest it depends on the method you choose. C is calculated by plugging A and B into the formula given to you in the box. Com August 7, – 6: There are a total of 5 steps as listed below. View all posts by DrillingFormulas. For example, a 10 ft drop in fluid level means a ten ft loss of hydrostatic pressure. Shut-In while Wireline Logging Operation Shut-in procedures while wireline logging operation are very critical for all drillling crew working on the rig.

The last two parts are about introduction to well control relating to kick prevention and detection, primary well control and secondary well for,ula. It is amazing sharing this great knowledge made easy by you guys out there. This is the pressure you expect to see on the drill pipe pressure gauge when first starting to circulate out the kick. TVD is used when calculating hydrostatic pressures.
Shut in conditions 5. There are a total of 5 steps as listed below; Step 1 — Calculation Three calculations must be determined before conducting volumetric well control. There are several topics in the well control. What do u recommend? Warning signs and shut in 4.

Domingues Basilio 2 foemula ago. The final piece of the simulator exam is learning to properly operate the choke to circulate out the influx while maintaining bottom hole pressure.
Since the length of Heavy Weight Forjula Pipe and Drill Collars are 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. Good morning, on which iwcf version are your questions based?
Brine Density with Temperature Correction Calculat July 14, at 9: It is especially helpful when determining what happens to casing pressure, drill pipe pressure and bottom hole pressure when hydraulic changes are made when circulating out a kick plugged bit, change in pump speed, washed out choke, plugged choke, etc.
