Production Methods

Competency Statement:

Apply basic production engineering principles to optimizing the reservoir exploitation scheme.

Learning Objective:

Upon completion of this module, the participant should be able to
  • select the optimal completion design and the proper surface and subsurface equipment for producing a flowing oil well efficiently and economically
  • optimize flowing well performance based on knowledge of inflow performance, vertical lift performance and surface choke performance
  • determine when artificial lift will be necessary in order to maintain oil production at desired levels, and select the most appropriate lift method for a given well
  • specify design and equipment requirements for placing a well on artificial lift

Assignment Instruction:

In this Learning Module, you will specify the completion design for Well 5A1-SW and evaluate its performance potential. By the time you complete this module, you should be able to optimize flowing well performance using nodal analysis principles, determine when artificial lift will be necessary in order to maintain oil production, and select the best lift method for a given set of operating conditions.

Well 5A1-SW has been recently drilled to the Upper/Middle sands. It is to be completed by selectively perforating the 7-inch casing, which has been cemented at a depth of 14400 ft. In this module assignment, you will review actual and estimated field data, select the general well configuration, and specify requirements for subsurface producing equipment. You will define the well's inflow performance relationship (IPR), determine its vertical lift performance for various producing rates, and establish surface flow parameters. You will then combine these analyses to define and predict the flowing well's performance. You will also review various artificial lift methods to determine how this well will be produced once it can no longer flow.
