SUMMARY

• In order to provide extra support in non
  conventional well control situations, ADCO has
  decided to form Well Control Expert Team or WCET
• Main criteria to formulate such team is to
• Select drilling personnel with good experience in
  drilling engineering
• Understand well control methods

4
SUMMARY

• To this end, Drilling Division has requested an
  advanced well control course to enhance the
  competency of the team
• Several proposals were received from various
  training providers available in the market
• Two courses were run in January and March 2003
  and will be discussed in the following slides

5
WCET OBJECTIVES

• The main objectives of the Well Control Expert
  Team are as follows

• Ensure that the team is familiar with all
  available well control methods and scenarios
• Ability to intervene whenever needed for well
  control incidents
• Ability to evaluate and analyze any well control
  situation
• Identify the potential problems along with the
  most effective way to bring the well under
  control
• Demonstrate learning curve and lesson learned

CASE STUDY

• Introduction

• Due to several well control incidents, that
  occurred in ADCOs fields. Well Control Expert
  Team concept was suggested
• The team is responsible for the intervention and
  control of the said wells whenever an incident
  occurs
• The team should have enough drilling experience
  to conduct the necessary analysis
• The analysis requires more advance courses in
  well control so that all issues are covered

12
CASE STUDY

• Introduction (contd)

• Advanced Well Control Course proved to be the
  best solution
• He decision was taken t contact all available
  training providers. Proposals were received from
  the following
• Aberdeen Drilling School (via BP)
• Randy Smith
• GSM
• Wild well Control
• Boots and Coots

13
CASE STUDY

• Introduction (contd)

• ENSPM PetroSkills were not directly contacted
  but the information was obtained via their course
  catalogue (by the author of this presentation)
• Members of ADCO Drilling Division have visited
  Shell Training Center in the Hague
• One of the observations noted that Shell provides
  an Advanced Well Control Course. The practical
  application is contacted using a real life well
  in the North West of Holland

14
CASE STUDY

• Introduction (contd)

• Based on this, a request was made to Shell to run
  the said course in their Training Center
• To run the said course, Shell has requested that
  a minimum of 8 candidates has to attend. This
  request was difficult to fulfill at that time due
  to the individuals work pressure
• Since there was no other training provider than
  Shell who uses real life well. ADCO has decided
  to run the anyway and COMPANY B was the candidate

15
CASE STUDY

• Course Overview
• 5-Day duration consisting of the following

• Well control basics
• Kick prevention, detection prediction
  techniques
• Pressure limits on casing kick tolerance
• Well control methods
• Handling gas in the wellbore

• Recognizing problems during well control
• Student hands-on (simulator practice)
• Stripping
• Well intervention
• Well control equipment

16
CASE STUDY

• Course Overview
• Contd

• Underbalanced drilling
• Student hands-on (simulator practice)
• Extendedreach horizontal well control
• HPHT well control consideration
• Case studies

• Slimhole well control consideration
• Student hands-on (simulator practice)
• Final exercise on simulator

17
CASE STUDY

• Dual Course Evaluation
• Course objectives achieved

18
CASE STUDY

• Dual Course Evaluation
• Improved job performance

19
CONCLUSION

• Considering the importance of formulating WCET,
  following the concluding remarks

• Ensure that course objectives are covered by the
  training providers
• List course content that serve ADCO needs
• Ensure the course is divided into
• Refreshment sessions (to fill the gap)
• Advanced theoretical session

20
CONCLUSION

• Contd

• Case studies related to advanced well control
• Advanced Simulator sessions
• End of course exam covering objectives
• Possibility to run the course on a real life well
  is highly recommended to enhance individuals
  skills
