This layered geology provides multiple development targets within a single field, allowing individual reservoirs and wells to contribute at different stages of the program.
Kettleman Nexus
The Four-Layer Energy Program
Oil: The Commercial Foundation
Kettleman Middle Dome has an established history of oil production. INNEX California Inc. combines historical completions, well logs, cores and production records with modern reservoir analysis to identify productive intervals, bypassed resources and recompletion opportunities.
Oil provides a marketable product alongside natural gas and forms an important commercial component of the wider development.
The Role of Oil
- Established production history and reservoir data
- Multiple reservoir intervals within the field
- Recompletion and additional development opportunities
- A complementary commercial product alongside natural gas
- Existing field knowledge, access and operating infrastructure
Natural Gas: The Link to Dependable Power
Natural gas connects Kettleman’s subsurface resources directly with the Nexus power strategy. The development plan gathers and treats produced gas for on-site generation, providing dispatchable electricity for the campus. Modular generation allows capacity to expand alongside demonstrated gas supply and customer demand.
Gas-fired generation complements solar production with controllable power across daytime and nighttime demand.
The Role of Natural Gas
- Dispatchable on-site electricity
- Local fuel supply for campus generation
- Modular expansion alongside customer demand
- Integration with solar and battery systems
- Recovery of generator heat where suitable applications are available
Solar: Power From the Surface
Solar forms the surface energy layer of Kettleman Nexus. Daytime generation reduces the fuel required to serve campus demand. The surrounding Kettleman region already supports commercial-scale solar generation, including an operating 20 MW solar facility.
Campus solar capacity is planned around available land, terrain, setbacks, environmental requirements and electrical needs. Battery storage supports the system by shifting available energy and providing short-duration flexibility.
The Role of Solar
- Daytime electricity generation
- Reduced gas consumption during periods of solar production
- Integration with gas generation and battery storage
- Scalable development alongside wells, roads and campus infrastructure
Geothermal: Energy From the Subsurface
Kettleman’s wells, geological information and subsurface resources provide the basis for evaluating geothermal energy as the fourth layer of the Nexus. Produced fluids and subsurface temperatures are assessed for useful heat recovery and electricity generation.
Where resource conditions support it, heat from produced water can be transferred through a heat exchanger to a separate working fluid and used for binary-cycle electricity generation.
The Role of Geothermal
- Recovery of value from subsurface heat
- Potential steady electricity generation where supported by resource testing
- Thermal energy for compatible industrial uses
- Additional use of existing geological, reservoir and well information
Kettleman Nexus
One Integrated Energy Stack
Each energy layer performs a different role. Oil supports commercial field development. Natural gas provides dispatchable power. Solar supplies complementary daytime generation. Geothermal adds another potential source of heat and electricity from the subsurface.
The program integrates these resources through a common development strategy covering wells, fuel treatment, power generation, storage, electrical distribution and customer demand. The platform expands in stages as production, generation and customer requirements develop.

Energy for data centers →The 1934 No. 58-19 Well
The Evidence Beneath Kettleman
Historical records supplied by INNEX Energy, LLC provide an important part of the modern Kettleman development story. In records relating to the 1934 No. 58-19 Temblor completion, INNEX Energy, LLC reports an early operating-committee reference records a flowing capability of 1,500 barrels of oil per day from a relatively thin Upper Temblor interval.
According to INNEX Energy, LLC, the 62-page well history contains core descriptions, observations of oil and gas in drill cuttings, and electric logs recording spontaneous potential and resistivity.
Historical records supplied by INNEX Energy, LLC indicate that the well subsequently produced nearly 100,000 barrels of oil and approximately 4.4 billion cubic feet of gas over approximately 3¼ years. The records also document a field-wide shutdown in 1939 attributed by the operator to a lack of market.
For INNEX California Inc., these records provide evidence to combine with modern geological interpretation, reservoir analysis and completion techniques to guide current development.
