- Buckling force during well completion and well intervention
- The student should be able to apply general engineering principles and theory learned in the course to solve related engineering problems
After completing this course the student should have general knowledge about:
- Sand control
- Life of well operations
- Fluids for completion, workover, intervention
- Well barriers
- Pressure testing of well completion and well intervention equipment
- Well control contingency for well completion and well intervention
- Proposed well intervention solutions for different types of well problems
Contents
The well completion part deals with lower and upper completion systems. The starting point is inflow performance and thorough treatment of skin factor is given. Openhole and perforated lower completions are discussed in detail. Upper completion design and installation are explained. Calculations include helical buckling of tubing sealed in packers, inflow performance, skin factors, gravel-packing, packer-setting depth and preloading in addition to other well completions scenarios.
The well intervention part covers pumping, wireline, coiled tubing and snubbing. We look at required surface equipment and well control elements. Mechanical well failures, well productivity issues, well intervention equipment, barriers, standards and regulations, different types of operations, choice of intervention technology and various relevant well engineering calculations are discussed. There is theoretical emphasis on tubular design and other mechanical engineering analysis in the course.
