The Tonkawa field, on the Kay-Noble county line in north-central Oklahoma, boomed in the early 1920s and is remembered locally as Three Sands, after the stacked sandstone pays that made it. It also gave its name to the Tonkawa sand, a stratigraphic term now used across the Mid-Continent. The boom camp that grew up around the wells is long gone, and the field today is a mature, waterflood-supported producer whose royalty interests are small, old and divided among a great many heirs.
North-central Oklahoma drew heavy drilling in the years after the First World War, and the Tonkawa field came in during 1921. It arrived in the middle of a decade of Oklahoma discoveries that also produced Burbank to the east and, later, the Greater Seminole fields to the south. The town of Three Sands sprang up on the field itself, complete with the usual boom-camp mix of company housing, boarding houses and businesses that followed drilling crews across the Mid-Continent in that era.
Development ran fast because the pays were shallow and stacked, letting a single lease produce from more than one sand. Leasing crossed farm and ranch quarters in both Kay and Noble counties, and the mineral reservations made during that rush created the fractional ownership recorded in the county clerks’ offices today. As with every unregulated 1920s Oklahoma boom, dense drilling and open-flow production spent the reservoir energy quickly, and rates fell from their early peaks within a few years.
Three Sands the town faded once the flush production ended; the field itself did not. Operators moved to water injection to sweep oil the early wells had bypassed, and the leases have produced at modest rates ever since. Operatorship passed steadily from the companies that opened the field down to Oklahoma independents and then to small operators who specialize in marginal wells. Royalty owners here have received small payments for a century, and should expect that pattern rather than a revival.
The field produces from stacked Pennsylvanian sandstones on the Cherokee Platform, including the sand that carries the field’s own name. These are shallow clastic reservoirs whose thickness and quality change laterally as the depositional systems that built them shift, so pay may be excellent on one quarter section and thin on the next. Traps are a mixture of structural closure and stratigraphic pinch-out. The shallow depth is what allowed such dense early drilling and what still permits low-rate wells to justify a pumping unit today.
Water injection took over once primary pressure was gone, and it is the reason a 1921 discovery still reports production. Injected water re-pressures the sands and drives oil toward producing wells, flattening the decline curve into a long tail. Operators also recomplete wells between stacked sands as each zone is drained, which effectively gives leases additional productive lives. For an owner, the result is a small but persistent income stream that responds to operator investment far more than to oil-price headlines.
Kay and Noble county royalty interests from the Three Sands era are usually small decimals attached to leases with long, complicated completion histories. A check stub will not tell you which sand is paying, whether the lease is inside an active injection pattern, or whether the operator has capital committed to the flood — and those are the facts that set value.

Because of the stacked sandstone pays that made it. The name attached to the boom town that grew up on the field in the 1920s, and locals have used it ever since. The field also gave its name to the Tonkawa sand, a stratigraphic term now used well beyond north-central Oklahoma.
Yes, at stripper rates. These are shallow, mature, injection-supported leases making small volumes per well. Royalties continue to be paid, but they are modest amounts, and no owner should expect a shallow century-old Oklahoma sand field to behave like a new horizontal play.
Yes. Partial sales are routine — owners often sell a portion to settle an estate or raise cash while keeping exposure to future production. The conveyance simply describes the fraction being sold. We can structure an offer for all or part of an interest and will put the terms in writing before you decide anything.
