Competency Statement: Diagnose production problems related to formation damage and recommend appropriate solutions.

Learning Objective: Upon completion of this module, the participant should be able to

  • Diagnose various types of formation damage and identify stimulation candidates.
  • Design a matrix acid stimulation treatment based on specific well conditions and reservoir characteristics.
  • Specify the materials, equipment and pumping schedule for a hydraulic fracturing procedure.
  • Apply traditional and modern sand control methods to optimize well productivity
  • Assignment Instruction: Well stimulation treatments, which are designed to restore or enhance well productivity, are of two basic types. Matrix treatments are performed at pressures that are below the formation fracture pressure; they are primarily designed to remove near-wellbore damage. Fracture treatments, on the other hand, are performed at pressures above the formation fracture pressure; they are designed to open up highly conductive flow paths between the reservoir and the wellbore, thereby bypassing near-wellbore damage and changing the flow patterns around the well.

    Sand control technolgy is built around preventing loose sand and other unconsolidated formation solids from plugging the formation or entering the wellbore. As you will see in this assignment, stimulation and sand control technologies are in some ways closely related, and under certain circumstances, may even overlap.

    In this assignment, you will carry out preliminary design work both for a matrix acid stimulation and a hydraulic fracture treatment, and will also select the appropriate sand control measures for a flowing production well. In each case, you will evaluate the nature and extent of the near-wellbore damage that has made stimulation and/or sand control necessary.
