Well Control

This course will teach participants about the physical principles and concepts related to maintaining and regaining pressure control of wells while drilling.  Starting from concepts of formation pressure, fracture pressure, and factors which affect inflow, participants will gain an understanding of the elements of primary and secondary well control methods.  Well design concepts to improve pressure containment and reduce risk of secondary well control situations will be covered in detail.  By listening to the well, participants will learn how to identify potential well control situations in advance of their occurrence.  A brief overview of well control equipment, their operation, and testing will be covered to the extent necessary for the participants to identify requirements in the well planning phase.  Classical well control methods will be covered and several well control problems will be worked using several standard well control worksheets. This course will complement and prepare the participants for other courses which are part of a certification process.

Day 1

Well Control, Well Pressure, and Industry Recommended Practices

  • Formation and fracture pressures
  • Leak off tests
  • Kick tolerance and MAASP
  • Gas expansion and casing seat selection
  • Introduction to API RP 59 “Recommended Practices for Well Control Operations”

The first day will teach participants about well control history, formation and fracture pressures, and leak off tests.  Kick tolerance and the determination of Maximum Allowable Annular Surface Pressure (MAASP) will also be covered.  API RP59 will be reviewed to familiarize participants with this important industry recommended practice. The day will end with conversations over gas expansion and casing seat selection.

Day 2

Kick Causes and Well Control Concepts

  • Kick causes and warnings
  • Primary and secondary well control
  • Lost circulation and kick detection
  • Shut-in procedures and shallow gas
  • Kill sheet basics and usage

Day two will focus on kick detection and well control basics.  Kick causes, warning signs, primary and secondary well control, and lost circulation, will be covered.  The day will end with discussions over shut in procedures, shallow gas, and kill sheet usage.

Day 3

Well Control Methods

  • Drillers method
  • Wait and weight method

The third day participants will learn about the classical well control methods.  Specific methods that will be covered include the drillers method and the wait and weight method.  Special concerns and changes needed to circulate out kicks on floating drilling operations will be discussed.  With an understanding of these methods the participants will calculate and set up various well control scenarios.

Day 4

Equipment

  • BOP equipment
  • Well control equipment

The selection, installation, operation, maintenance, and testing of BOP equipment will be discussed on this day.  Important equipment selection criteria such as pressure limits, auxiliary units, and closing units will be discussed.  Exercises related to equipment sizing will be performed.

Day 5

Subsea Equipment

  • Subsea equipment
  • Well control exercises

The last day of the course will cover subsea equipment and several well control exercises.

Learning activity mix

Drilling supervisors, drilling engineers, drilling superintendents, and drillers who are going on to full IWCF or IADC certification will greatly benefit from this course.  This course would benefit all personnel who design, plan, and manage drilling operations.

Participants should have general math and science skills, along with a minimum of one year drilling related experience.  Hand held calculators will be needed for class exercises.

Currently there are no scheduled classes for this course.
