Completion Specialists, Inc. (CSI) was established by Shelby White in 1992 as COPECO, which provided a single-person consulting engineering service centering on drilling, completion, and workovers. In 2003, Shelby changed the name to Completion Specialists, Inc. to reflect the company’s redirected focus on providing specialized completion engineering services. He added additional people to the company, and in-turn, enabled employees to become owners in the company. The company is 100% employee owned. CSI has had a gratified history of providing high-quality engineers during the up and down cycles associated with the oil and gas industry.

As of October 2023, CSI formerly provided engineering services, but going forward is still capable of suppling our clients with the most technically astute workforce the industry has to offer. Our rich history in providing technical expertise has taken us around the world overseeing the evolution of many of the world’s first major capital projects. We continue to augment CSI and client offices with high-quality experienced contract technical professionals and advisors who specialize in the drilling, completion and subsea phases of well planning, design, and construction for any major capital project.
