SANCHEZ O BRIEN 1981-A DRILLING CO
As a private trailblazer in the Drilling Oil & Gas Wells sector, SANCHEZ O BRIEN 1981-A DRILLING CO delivers turnkey deep-hole drilling services, well casing execution, and on-site safety management that embody the rugged standards of SIC 1381 contractors; its crews serve independent operators and regional majors who rely on its reliability to bring West Texas and Gulf Coast prospects online. The firm’s disciplined fleet of rigs, mud-logging, and completion support target customers seeking efficient well delivery and compliance with federal and state drilling permits. Yet, the business must continually navigate material risks from volatile commodity pricing, weather disruptions, and the evolving regulatory environment overseen by the SEC and state oil & gas commissions, all while safeguarding workers in remote field conditions. With the most recent public disclosure being the Form 10-Q filed November 1999, stakeholders watching industry shifts should monitor developments closely—CIK 350212 helps track their history, and you can view live SEC filings on Earnings Feed.
