Sacgasco Limited (ASX:SGC) is an Australian-based energy company focused on conventional oil and gas exploration, development, and production in the Sacramento Basin of California, the Alberta Province of Canada, and offshore Palawan Island in the Philippines; its core assets include a portfolio of natural gas and oil producing wells, prospects, and discoveries at various exploration and appraisal stages, such as Rio Vista Gas Field production and development assets in California, a 30% working interest in the Red Earth oil asset producing approximately 300 barrels of oil per day in Alberta, and royalty interests in six oil discoveries across three service contracts plus an option to participate in deepwater drilling in SC 58 in the Philippines; natural gas activities encompass hydrogen and helium opportunities near under-supplied markets. Founded in 2005 and headquartered in Fremantle, Western Australia, the company targets local Californian and Canadian markets alongside LNG export potential, operating through oil and gas exploration/appraisal and oil production segments with interests in undervalued, infrastructure-supported assets. In August 2024, Sacgasco changed its name from Australian Oil Company Limited following shareholder approval, reflecting a strategic rebranding amid ongoing director remuneration via equity issues and options grants through 2024-2025; earlier acquisitions include 100% of Rio Vista Gas Field wells in 2018 for production diversification, a 30% stake in Alberta's Red Earth asset in 2020 for cash flow generation, and BCP Energy International (owner of Nido Petroleum) from Bangchak Corporation in July 2021, bolstering its Philippines portfolio with operatorship in SC 54 and participation in additional service contracts.
