Drilling and Workover Fluids

Competency Statement:

Select the appropriate drilling/workover fluid for meeting well objectives and, minimizing formation damage with no impact on the environment.

Learning Objective:

Upon completion of this module, the participant should be able to
  • evaluate the features, benefits and limitations of various mud systems and additives, and select the one most appropriate for a given well
  • specify controls on fluid properties in order to optimize drilling and workover operations

Assignment Instruction:

Drilling and completion fluids are essential to safe and successful well operations. In this assignment, you will select the appropriate fluids for drilling and completing Well 5A1-SW, monitor their properties, and recommend changes as needed. By the time you complete this module, you should be able to evaluate the features, benefits and limitations of various mud systems and additives, and specify controls on fluid properties for optimizing drilling and workover operations.

The AFE for drilling Well 5A1-SW has been approved, and operations are getting underway. Once drilling begins, your job will be to closely monitor the properties of the mud system you have selected, and to make changes in the mud system as operating conditions may require.
