- An Immediate retest after review is available or within 45 days of the initial test failure. The delegate must score a 60% or better to qualify for the re-test option.
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
- 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
- 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.
