Who should attend?

  • This training is intended to raise the participants' awareness on the problems and consequences of a blow out and to enable them to understand the causes of a kick and also to control a kick correctly with a good knowledge of well control methods.
Public :
  • This training is for all the personnel involved in water, geothermal or oil/gas drilling operations linked to the detection of a kick and well control methods (drilling engineers, mud engineers, supervisors, tool pushers, drillers, assistant drillers, etc.)

Level : Proficiency

Course Content

  • INITIAL TEST ON WELL CONTROL

  • PRESSURE ANALYSIS & KICK CONTROL

      • Reminder on hydrostatic and hydrodynamic pressures.
      • Relationship between various pressures in the well.
      • Definition of gas law and migration.
      • Causes and signs of abnormal pore pressure.
      • Frac pressure and MAASP (LOT and FIT).
      • Causes and signs of a kick, impact of WBM or NABM.
      • Precautions to be taken to avoid kicks.

  • WELL CONTROL

      • Procedures to follow in case of a kick while drilling or tripping (surge and swab).
      • Well shut-in methods: hard and soft methods.
      • Observation and evolution of pressures after shut in and selection of the stabilized pressures.
      • Exercises on “Kill sheet”.
      • Well control methods to control a kick:
      • Driller's method.
      • Wait and weight method.
      • Comparison/differences between each method (advantages and drawbacks).

  • PARTICULAR CASES

      • Incidents during circulation.
      • Shallow gas.
      • Volumetric method.
      • MAASP.
      • Deviated well.
      • Kick while running casing or during cement jobs.

  • SURFACE WELL CONTROL EQUIPMENT

      • BOP stack: types, annular BOP, BOP rams, etc.
      • Diverter.
      • BOP control unit (“Koomey” unit).
      • Choke-manifold and remote choke control panel.
      • Mud-gas separators.
      • Function tests and pressure tests.

  • EXERCISES

      • Practice on simulator as requested by IWCF.
      • Exercises on: principles and procedures, kill sheet and well control equipment.

  • SUBSEA SPECIFICITIES

      • Difference between surface and subsea BOP.
      • Specific equipment between seabed and rig floor.
      • Well control with a subsea BOP (friction losses in choke line).
      • Riser margin.
      • Subsea BOP control unit.

  • IWCF CERTIFICATION

      • Test on principles and procedures.
      • Test on well control equipment.
      • Practical assessment on simulator.

Learning Objectives

  • At the end of this training, participants will be able to:
  • identify and calculate the different pressures in a well,
  • understand the causes of the kicks,
  • recognize/analyze the signs of a kick to shut in the well with the minimum volume of gain,
  • know the well control methods and demonstrate the ability to shut in the well (driller) and killing the well (supervisor),
  • detect possible incidents during the well control and react correctly,
  • to be certified IWCF Level 3 or 4 on well control.

Ways & Means

  • Course material (PPT, PDF, Word).
