UNOCAL CORP

Unocal Corp operates in the crude petroleum and natural gas segment (SIC 2911/1311), developing upstream exploration, production, and midstream logistics that serve major refiners, petrochemical firms, and energy-hungry industrial customers across North America and Asia; its portfolio includes crude lifting, natural gas gathering, and transport services built around integrated field operations and storage assets. The company balances capital-intensive projects with commodity price exposure, stringent environmental permitting, and compliance with federal and state drilling regulations, while safety, pipeline integrity, and leasehold obligations remain material risks that investors should weigh alongside geopolitical shifts in demand. The latest Form 8-K filed in December 1999 reaffirmed its disclosures and corporate governance updates, keeping stakeholders aware of management-level changes affecting ongoing strategy.
