The Kern River field, on the bluffs just northeast of Bakersfield, is the textbook example of what steam can do for heavy oil. Discovered in 1899 with a hand-dug well, the field has produced more than two billion barrels of roughly 13-degree API crude from shallow, unconsolidated sands. Long operated by Chevron and its predecessors, Kern River is cited in petroleum engineering courses worldwide as the reference case for steam-flood recovery — and its royalty owners have collected checks across three different centuries.
Kern River was discovered in the spring of 1899, when James and Jonathan Elwood struck oil in a hand-dug shaft near the river northeast of Bakersfield. The strike set off one of California’s great early booms: within a few years hundreds of wooden derricks covered the bluffs, and the field helped make Kern County the center of the state’s oil industry.
By the mid-twentieth century primary production had slowed to a trickle, with only a small fraction of the oil in place recovered — the heavy crude simply would not flow at reservoir temperature. Steam experiments beginning in the early 1960s changed everything. Cyclic steaming and then pattern steam drives lifted the field to a second peak of roughly 140,000 barrels per day in the mid-1980s.
Getty Oil built much of the modern steam operation, and Texaco’s 1984 acquisition of Getty brought the field into what became Chevron in 2001. Chevron has since operated Kern River as one of the most intensively engineered shallow oil fields anywhere, with thousands of wells and cogeneration plants supplying steam. The two-billionth barrel was produced in the 2010s, more than a century after discovery.
Kern River production comes from the Pleistocene-to-Pliocene Kern River Formation: a stack of unconsolidated, highly porous sand channels interbedded with silts and clays, from roughly 400 to 1,300 feet deep. The sands were laid down by ancestral Kern River drainages, and the trap is a gentle homocline sealed updip by tar and fine-grained beds. Porosity commonly exceeds 30 percent, and oil saturation was originally very high, but the crude is viscous heavy oil — ideal geology for steam, since the reservoirs are shallow, thick, and continuous.
Kern River is the world’s reference steam flood. Operators inject steam in patterns — continuous steam drive — and also cycle individual wells with huff-and-puff steaming. Heat cuts the oil’s viscosity by orders of magnitude, letting gravity and pressure move it to closely spaced producers. Royalty income here is a direct function of that thermal program: steam generation consumes natural gas, so project economics move with the gas-to-oil price relationship, and injection operates under CalGEM permits. California’s setback law affects portions of fields near development, though Kern River’s core sits on long-established oil land.
A Kern River royalty is a claim on one of the best-understood oil recovery projects on earth, with shallow decline and a major operator. That said, the field is mature, California permitting for new work is restrictive, and thermal barrels only flow while steam economics justify injection. A fair valuation weighs your leases’ actual well count and activity, not just the field’s famous name.

The great majority of the field has long been operated by Chevron, which acquired it through the Texaco and Getty lineage. Your check stub or division order will name the operator for your specific leases, which is the starting point for any valuation.
Steam drives replace reservoir energy rather than just draining it, so production is sustained as long as injection continues. Kern River wells have produced for decades under steam. The flip side is that volumes depend on the operator’s ongoing steam investment rather than on natural flow.
