Garland Field holds a specific place in Wyoming history: the United States Geological Survey records it as the source of the first commercial hydrocarbon production in the Bighorn Basin, established in 1906 from a small Cretaceous reservoir in the Frontier Formation. The field lies in Big Horn County in the northern basin, extending toward the Park County line, and it is a good illustration of how these fields actually developed — a modest shallow discovery that only became substantial decades later when drilling reached the Paleozoic section far beneath it.
The 1906 discovery was small by any later standard. Oil was found in a limited Frontier Formation reservoir, and the significance was less the volume than the proof: the Bighorn Basin, a landscape of obvious surface anticlines ringed by mountains, could actually produce. That result set off systematic drilling of the basin’s folds over the following two decades, the campaign that eventually found Grass Creek, Byron, Elk Basin, and Oregon Basin. Garland was the opening move rather than the prize.
Garland grew into a genuine field through the 1920s and 1930s. Contemporary industry reporting on Rocky Mountain development in the late 1930s noted substantial extensions to the black-oil productive area of the Garland field, the kind of routine notice that marks a field being methodically enlarged rather than sensationally discovered. Deeper drilling reached the Pennsylvanian Tensleep sandstone and the Mississippian Madison limestone, the Paleozoic reservoirs that carry most of the Bighorn Basin’s oil and that dwarfed the shallow Cretaceous pay found in 1906.
From mid-century onward Garland followed the standard northern-basin arc: unitization to allow reservoir-wide management, water injection to hold pressure in the Paleozoic pays, and a long decline into stripper-rate production that has continued for decades without ending. Operatorship in this part of the basin has consolidated repeatedly, with the large legacy positions passing between major companies and then to private operators specializing in mature waterfloods. Owners should confirm current operatorship from a recent division order rather than from historical accounts of the field.
Garland is an anticlinal field in the northern Bighorn Basin, and its productive section spans two very different systems. The original 1906 pay was a small Cretaceous Frontier sandstone reservoir at shallow depth. The volumes that made the field matter came later from the Pennsylvanian Tensleep sandstone and the Mississippian Madison limestone beneath it, the same Paleozoic pair that produces at Elk Basin, Frannie, and Byron along the northern rim. Tensleep permeability varies sharply with cross-bedding and cementation, which is why sweep efficiency, not oil in place, has always been the limiting factor here.
Water injection is the recovery story at Garland, as it is across the northern Bighorn Basin. Unitized operations allowed pressure to be maintained across the Paleozoic reservoirs rather than lease by lease, and that engineering is the reason a field opened in 1906 still produces. The economics of these floods are unglamorous: high water cuts, small per-well oil rates, and a decline curve so shallow it is nearly flat over a decade. That flatness, rather than any expectation of growth, is what gives a Garland royalty its remaining value.
Garland minerals are among the oldest privately held oil interests in Wyoming, and the title reflects it — long chains of heirs, fractional decimals carried to many places, and occasional gaps where a probate was never completed in the county. Production is stripper-grade and injection-supported, so it declines slowly and pays for far longer than a first look at the monthly amount suggests.

County-level well data, production charts, and selling guides for the counties this field spans:
The USGS records the basin’s first commercial hydrocarbon production as established in 1906 from a small Frontier Formation reservoir at Garland. Earlier shows and seeps were known across the basin, but Garland is where commercial production began.
Most modern Garland production is from the Paleozoic section — the Tensleep sandstone and Madison limestone — rather than from the shallow Frontier pay found in 1906. Your division order or check stub will name the unit or well, which identifies the producing interval.
That is a judgment only you can make, but the arithmetic is worth seeing. Injection-supported Bighorn Basin production declines very slowly, so these interests carry long remaining lives, and a written offer lets you compare a lump sum against that stream before deciding anything.
