Summary
Energy Advisors Group has been retained to market Trio Petroleum’s California portfolio, which includes three operated oil properties: South Salinas, McCool Ranch and Union Avenue. These three properties offer immediate production upside, drill ready permits and large undeveloped reserves. The individual properties are well-suited for buyers looking for operated positions or joint venture development opportunities. The Trio portfolio is located in California’s Salinas and San Joaquin Basins and provides strong growth potential.
Across all three properties, there are more than 170 potential drilling locations identified using modern 3-D seismic. Existing infrastructure includes well pads, pipelines, and facilities. Near-term projects could add more than 600 BOPD through workovers and restarts. Long-term development targets the Monterey Formation, Vaqueros Sandstone and Santa Margarita reservoirs. This three-part package offers large reserves, established facilities, and strong potential for growth and enhanced recovery.

Lets look at each of the three property groups:
1---
South Salinas is the largest property in the package. It includes two major fields, Humpback and Presidents, and has 2- active permits ready for drilling. The estimated oil in place is about 2.2 billion bbls, and the estimated gas in place is about 1.3 trillion cubic feet. A 2024 reserve report filed with the SEC shows a PV10 value of over $130 million for phased development. Additional upside includes a workover on the HV-3A well, which could open 975 feet of new perforations, and potential for carbon capture and enhanced oil recovery using existing CRC pipelines.
