An authority for expenditures (AFE) would not be complete without defining and developing costs for the completion equipment used for the well. Defining what is needed is an important part of well planning.
Components of a completion equipment
The completion equipment consists of downhole tools related to the tubing string. These items include:
- Packers
- Seal assemblies
- Flow couplings
- Blast joints
- Landing nipples
They are dependent primarily on tubing size and fluid content.
Packers
The packer is designed to divert formation fluids into the production tubing. It is selected according to production-casing size, bore size requirements, tensile loading, and seal-assembly type. In addition, H2S-serviceable packers contain seals that are approximately 100 times more costly than the standard rubbers.
Blast joints
Blast joints are thick-walled tubulars placed in the tubing string opposite the perforations to minimize the damage from erosion by the produced fluids. Their cost is dependent on tubing size and number of joints.
Seal assembly
The seal assembly is an important part of the completion equipment. The cost is affected by the required number of seal units, the connection type, and the pipe size.
