Who should attend?

  • This course raises the awareness of kick prevention and knowledge of well control methods and procedures.
Audience :
  • All personnel concerned with drilling and completion operations involved in operations linked to the detection of a kick and well control: 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 during running of casing or during cement jobs.

  • SURFACE WELL CONTROL EQUIPMENT

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

  • EXERCISES

      • Practice on a simulator, training for the IWCF certification.
      • Exercises on: principles and procedures, kill sheet and well control equipment.

  • SUBSEA SPECIFICITIES

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

  • IWCF CERTIFICATION

      • Written test on principles & procedures.
      • Written test on equipment.
      • Practical assessment on simulator.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • identify and calculate the various pressures in a well,
  • understand the causes of the kicks,
  • recognize/analyze the signs of a kick in order to shut in the well with the limited amount of gain,
  • follow and apply shut in methods in order to secure the well after a kick occurrence,
  • know the well control methods and demonstrate the ability to shut in the well (driller) and killing the well (supervisor),
  • detect potential incidents during well control and take appropriate actions,
  • obtain the level 3 or 4 IWCF certification on “Well Control”.
