What are Completion Consultants?

Completion consultants, or completion supervisors, supervise workover and completion operations on behalf of contract oil and gas operating companies. They manage hydraulic fracturing of vertical and horizontal wells, coil tubing cleanout, running tubing, casing and frac strings, setting down-hole pumps and rods, as well as pumping unit installation.

Completion supervisors oversee the operator’s completion plan during the contract term, handling various aspects of workover and completions engineering assignments and assisting in preparing completion, testing and workover procedures.

  • Following safe operating practices and ensuring compliance with environmental, safety and regulatory requirements.
  • Assisting in the engineering design of all completion programs as well as the fracture treatment of all new drilling wells; preparing completion, testing and workover procedures.
  • Ensuring that workover and completion operations are carried out with best oilfield practices and in accordance with program and all relevant company standards.
  • Making regular reports to the production engineer on the progress of operations.
  • Aiding in implementing steps for reducing environmental impact due to drilling operations.
  • Preparing written engineering well workover briefs for wellsite supervisors.
  • Assisting in the monitoring of all AFE’s for well work, running economic backup and justification calculations for AFE submittals and monitoring expenditures against AFE amounts.
  • Reviewing well production on daily basis to ensure that wells are optimized as to productivity.
  • Providing engineering support on a variety of subjects, including completion designs, workover and fishing jobs, and production facility modifications.


Completions supervisors are highly knowledgeable and skilled in their industry with many having 20 to 30 years of oilfield experience. However, it is not uncommon for individuals with 10 to 15 years’ experience to break into these roles.

Completion supervisors are generally between 35 and 50 years old with a weighted average between 50 and 70. However, some individuals are able to begin a career as a completion consultant in their late 20s, especially those with a background in engineering.
