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.
