NINE

Nine Energy Service, Inc.

A Houston oilfield-services company that helps prepare newly drilled horizontal wells for oil and gas production, offering cementing, wireline, coiled tubing, and completion tools used by energy operators across North America. It was born in 2013 from the merger of three service firms: Northern States Completions, Integrated Production Services, and CDK Perforating. Its name comes from the idea of "nine out of ten," since a perfect "ten out of ten" is impossible in the oilfield.
