C&J Well Services, LLC

C&J Well Services, LLC is a California-based oilfield services company specializing in well construction, well completions, well servicing, and complementary oilfield services for oil and natural gas production companies. Operating under the mission of 'Maximizing the Productive Life of a Well,' the company provides rig-based and coiled tubing-based well maintenance and workover services, recompletion services, fluid management, fishing and rental services, cementing services, and plug and abandonment services. The company operates workover and servicing rigs ranging from 200 to 900 horsepower for new well completion, maintenance, and shallow drilling, and maintains a fleet of specialized equipment including vacuum trucks, frac tanks, foam air units, and hydro cranes. Founded through the legacy of Pool Well Services and subsequently held by C&J Energy Services and NexTier Oilfield Solutions before being acquired by Basic Energy Services in March 2020, C&J Well Services was acquired by Berry Corporation in October 2021 via a bankruptcy auction for approximately $43 million. As of December 2025, Berry Corporation merged with California Resources Corporation (CRC), and C&J Well Services now operates as part of CRC's California operations portfolio. The company employs 500–1,000 people and is headquartered in Bakersfield, California. C&J Well Services is widely regarded as a leading provider of well servicing and plug and abandonment services in the California basin, serving the largest and most active operators in the state.
