Questions around this topic aim to increase awareness around the following themes…:

As the kick is circulated out, several things can happen. The choke can plug, the pumps can stop, you can loose a jet etc. During the circulation you may also have built too much overpressure or have moved into underbalance and will need to adjust. The app will run through several of these scenarios and guide you through to the right answer. These questions are asked in the right sequence starting with “starting to circulate” and will continue until the influx is circulated out past the choke. Several problems are given on the way . Each exam has one Circulating Out scenario from one spesific case.

Questions around this topic aim to increase awareness around the following themes…:

These topics are usually not part of exams given at standard well control courses but may be useful for the candidate to understand and to know how to calculate.

• Calculating Kick Tolerance:
  • The KickDrill App explains this issue further and gives an example of how to calculate Kick Tolerance. Can be used as a template for calculating KT on your well.
• Volumetric method when SIDPP is not available
  • Case scenario of time taken and volume required to evacuate out gas when SIDPP is not available
• Calculating required Depth and amount of test fluid required during a Negative Pressure Inflow Test
  • Usually not given at exams but the app goes through a case scenario
