CASTLE ENERGY CORP

Castle Energy Corp operates in the Crude Petroleum & Natural Gas industry, staking its position among SIC 1311-style producers that move barrels from discovery to delivery and offering exploration, drilling, and production services to refiners, utilities, and regional energy marketers in search of steady supply. The company’s upstream focus on owned and leased wells is paired with engineering support for artificial lift and reservoir management, while its marketing arm negotiates midstream commitments to place barrels for large-scale fuel consumers. By homing in on core customers that demand reliability for refining schedules and power generation runs, Castle underscores a service model that blends geological know-how with commercial logistics. Material risks include extreme oil and gas price swings, permitting delays, and increasingly stringent environmental regulation governing emissions, waste handling, and offshore/offshore siting, which all factor into capital planning and borrowings; its most recent disclosure is a Form 10-K filed December 1999.
