Well Planning

Competency Statement:

Identify, monitor and evaluate drilling, workover, stimulation and well servicing proposals and activities in the context of optimizing the overall reservoir exploitation scheme.

Learning Objective:

Upon completion of this module, the participant should be able to
  • contribute to the well planning process by understanding the reservoir engineering aspects of the proposed work and having a knowledge of drilling, workover and well servicing fundamentals
  • work with the geologist and the drilling engineer to select well locations, target depths and casing points

Assignment Instruction:

Long-term exploitation strategies for this reservoir are currently being considered for the Upper/ Middle Sand reservoir. Management has appropriated funds for continued drilling, and has already approved a new well proposal for Block 5A1-SW. In this assignment, you will recommend the target depth and radius for well 5A1-SW. You will determine what mud weights to use during drilling, specify casing points, and decide on formation evaluation requirements. This reservoir has been on production for just over two years. A total of six wells have been drilled, one of which was abandoned. Production is currently averaging about 2000 barrels of oil per day under solution gas drive at well over its bubble point pressure. These wells, although initially designated as "Upper Sand" producers, expose both the Upper and Middle sand reservoirs.
