Nine Energy Service, Inc.

Nine Energy Service, Inc. (NINEQ) is a specialist provider of onshore completion services, primarily targeting the development of unconventional oil and gas resources across North American basins and internationally.

The company's service portfolio includes: Cementing services: This involves expertly blending high-grade cement, water, and various solid and liquid additives to create a robust slurry. This slurry is then pumped into the annular space between the well's casing and the wellbore. Completion tools: NINEQ supplies a comprehensive range of products for both open hole and cemented applications. These tools encompass liner hangers and their accessories, fracture isolation packers, frac sleeves (often integral to pinpoint frac sleeve systems), stage one prep tools, casing flotation tools, specialized open hole float equipment, disk subs, composite cement retainers, and centralizers. Wireline services: The firm offers specialized wireline operations, notably plug-and-perf completions. This multi-stage technique for cased-hole wells precisely deploys perforating guns and isolation tools to specific depths. Coiled tubing services: NINEQ provides coiled tubing operations for various wellbore intervention needs, utilizing a continuous steel pipe that is transported to the wellsite on a large spool. Founded in 2011, the company was initially named NSC-Tripoint, Inc. before adopting its current name, Nine Energy Service, Inc., in October of the same year.

Its corporate headquarters are located in Houston, Texas. A significant development occurred on February 1, 2026, when Nine Energy Service, Inc., along with its affiliates, initiated a voluntary reorganization process by filing for Chapter 11 bankruptcy in the U.S. Bankruptcy Court for the Southern District of Texas.
