Augusta is the field that came first. Exploratory wells found gas and oil near Augusta, Kansas in late 1914 — a year before the more famous Stapleton No. 1 opened El Dorado a few miles north — and the results encouraged Henry Doherty’s Cities Service to press on with the geological mapping programme that made Butler County the centre of the Kansas oil industry. Today Augusta is a shallow, mature, waterflood-supported field, and its royalty ownership has been divided and redivided for well over a century.
Cities Service hired the geologists Charles Gould and Everett Carpenter to map prominent anticlinal structures in Permian limestone across Butler County, and the Augusta discovery in late 1914 gave that work its first encouragement. It was an early and important demonstration that structural mapping could find oil more reliably than drilling near seeps or guessing. The Augusta field and the El Dorado field that followed in October 1915 together made Kansas a significant producing state almost overnight and permanently changed how American exploration was organised.
Butler County boomed. El Dorado grew from around 3,000 residents to more than 10,000 within three years, and the whole county filled with drilling crews, supply houses and refineries. By 1918 the El Dorado field alone was producing close to 29 million barrels a year, roughly nine percent of the national total, and the wartime importance of that output is still part of local memory. Augusta shared in the same infrastructure and the same leasing pattern, with mineral reservations carved out of farm quarters across the townships.
After the boom the field settled into the long maintenance phase that still defines it. Water injection replaced flush primary production, well counts stabilised, and the operating base migrated from Cities Service and its successors down through Kansas independents to small operators who specialise in shallow marginal wells. The town of Augusta remains an oil town in character. For owners, the field is now what most of central Kansas is: many wells, small rates, long lives and very fragmented royalty title.
Augusta produces along the flank of the Nemaha Ridge, the buried granite high that runs diagonally across eastern Kansas and creates the anticlinal closures Gould and Carpenter mapped at the surface. Shallow Permian and Pennsylvanian sands — the locally named Varner among them — supply much of the pay, with deeper Ordovician carbonates producing where the older section is preserved against the ridge. Depths are modest, which is why the field could be drilled densely with early equipment and why low-rate wells still justify a pumping unit today.
The field moved from flush production to pressure maintenance early by national standards, and water injection has carried it for most of the past century. Injected water re-pressures the producing sands and sweeps oil toward producing wells, converting a steep primary decline into a long, shallow one. There is no headline tertiary project here; longevity comes from routine work — injector conversions, pattern realignment, workovers and returning idle wells to service. Whether a given lease is inside an active injection pattern is the first question that determines what an interest is worth.
A century of Kansas estates has left Butler County royalty ownership scattered across hundreds of small undivided fractions, many held by heirs who have never seen the property. Those interests are real, but they cannot be priced from a check stub, because the stub does not say whether the lease is under active injection or simply coasting toward abandonment.

Augusta. Exploratory wells found gas and oil near Augusta in late 1914, and that success helped push Cities Service to keep mapping Butler County anticlines. The Stapleton No. 1 opened the larger El Dorado field on October 5, 1915. The two fields are separate but share the same geological setting and much of the same history.
Yes, at mature shallow-field rates — modest per well and supported by water injection. It is stripper economics rather than a growth story. Royalties continue to be paid on many leases, and the interests are typically small fractions inherited through several generations of Butler County families.
Start with the Butler County Register of Deeds and trace the original reservation forward through every deed and probate. Century-old Kansas interests were often partially conveyed along the way, so what you hold today may be a fraction of the original grant. If you receive checks, the division order states your decimal directly.
