Company overview
PIONEER ENERGY SERVICES LLC anchors its operations in the Drilling Oil & Gas Wells space (SIC 1381), delivering rotary drilling services, directional drilling expertise, and ancillary well support equipment to exploration and production teams from independents to majors across the Gulf Coast and beyond. The firm relies on experienced crews who maintain rig fleets and drilling fluids programs calibrated to the Gulf of Mexico shelf, shallow domestic, and some international prospects, aiming to keep wells on depth while managing NPT and safety metrics for operators driven by disciplined capital programs. Material risks swirl around the same dynamics its customers face: commodity-price swings that can abruptly idle rigs, evolving federal and state environmental regulation, and the need to satisfy OSHA and BSEE compliance while protecting margins in a highly competitive subcontracting market. The last available disclosure remains a Form 10-Q filed Nov 1999, so investors looking for updates should monitor filings closely; CIK 320575 should be the anchor when searching.
