Course Outline:
Well Control Equipment

  • Covers why controlling pressure in the well is important
  • The role of drilling fluid in controlling the well
  • BOP stacks and how they work
  • The function of other equipment used in well control activities.
  • Instrumentation used in well control operations

Units of Measure

  • Units of measurement used in the oil field
  • Calculating surface area and volume
  • Calculating pressure
  • The definition of density and how it is measured

Hydrostatic Pressure

  • Discusses the linear relationship between depth and pressure and how to calculate it
  • The importance of true vertical depth (TVD) and how the hydrostatic pressures in different sections of a well add to determine bottom hole pressure

Pressure Balance

  • Discuss how the drill string and annulus can be represented as a U-tube
  • Differences between normal, abnormal and subnormal formation pressures, and balancing formation pressures with hydrostatic pressure of the drilling fluid

Causes of Kicks

  • Discuss how to identify the different conditions that can cause a kick
  • Describe how a kick develops
  • Describe the warning signs and the indicators of kicks
    Describe the effects of a gas kick

Controlling the Well

  • Discuss the steps involved in shutting in the well when a kick is detected
  • How closing the well can be used to increase bottom hole pressure and stop flow
  • Why responding quickly to a kick is important, and how migrating gas in a shut-in well effects surface and downhole pressures

Restoring the Well

  • Discusses the special problems that kicks from shallow formations present
  • Why maintaining constant bottom hole pressure is important when handling a kick, and the steps in two methods used to restore normal circulation

The Drillers Well Control Method

  • Provides overview of the Driller’s Method
  • Provides Step by Step details of the Driller’s Method.
  • Provides a specific example of an application of the Driller’s Method
  • Discuss two Driller’s Method rules, and the Driller’s Method Worksheet will be introduced.
  • Discuss calculations involving shut-in drill pipe pressure (SIDPP) and shut-in casing pressure (SICP), and an explanation of maximum shoe pressure

Wait-and-weight Control Method

  • Provides a general description of the Wait-and-Weight Method
  • Discusses Drill Pipe Pressure Profile
  • Discusses details of Wait-and-Weight Method and discusses the Wait-and-Weight Method worksheet.
  • Compares the advantages and disadvantages of the Driller’s Method and the Wait-and-Weight Method.
