Chase-Silica spreads across Rice, Barton and Stafford counties on the flank of the Central Kansas Uplift, and by the Kansas Geological Survey’s accounting it stands at roughly 307.6 million barrels of cumulative oil — the largest total of any Kansas field. Production began in 1931 from shallow Arbuckle dolomite and stacked Lansing-Kansas City limestones, and it has been carried for decades by waterflood rather than by new drilling. What is left today is a dense population of low-rate stripper wells and an unusually fragmented mineral and royalty ownership base built up over ninety years of estates, deeds and partitions.
The Central Kansas Uplift gave up one large field after another between the mid-1920s and the early 1930s, first through surface structure mapping and then through frankly speculative drilling. Chase-Silica came in during 1931, and the Silica pool in Barton County — with roughly a sixth of its area reaching into Rice County — quickly ranked among the state’s top producers. Operators found that a single lease could carry pay in both the Arbuckle at the base of the section and the Lansing-Kansas City limestones several hundred feet above it, which made even modest tracts worth developing on close spacing.
Development ran hard through the 1930s and 1940s on the strength of shallow depths and cheap cable-tool and rotary drilling. Because the field was leased parcel by parcel across three counties of farm and ranch ground, the resulting royalty base was wide and shallow: hundreds of separate leases, many of them held by families who had homesteaded the section. Kansas Geological Survey records show cumulative production of about 271.6 million barrels through 1994 from more than 800 producing wells, with the field continuing to add barrels slowly in the decades since.
The modern chapter is a waterflood chapter. Pressure fell off long ago, and unitized and lease-level injection has done most of the work since mid-century, holding gross rates steady while oil cuts thinned. Operators changed hands repeatedly as majors sold down to Kansas independents and then to small stripper-focused operators. For mineral and royalty owners, the practical effect is a long tail: small monthly checks that persist for decades, punctuated by workovers, injection pattern changes and occasional recompletions from one pay zone to another.
Chase-Silica produces from two very different systems stacked over one another. The deeper target is the Cambrian-Ordovician Arbuckle dolomite, a karsted, weathered surface draped over the Central Kansas Uplift where porosity is erratic but locally excellent. Above it sit the Pennsylvanian Lansing-Kansas City limestones, thin oomoldic and algal-mound intervals that trap oil in subtle structural and stratigraphic closures. Depths are shallow by industry standards, generally a few thousand feet, which is exactly why the field could be drilled densely and why marginal wells remain economic to keep on pump.
Primary production drained the easy oil quickly, and secondary recovery has defined the field ever since. Waterflooding — injecting produced brine back into the Arbuckle and Lansing-Kansas City pay to re-pressure the reservoir and sweep oil toward producers — is the reason Chase-Silica has kept producing across four generations of owners. Injection is not glamorous, but it changes valuation: a waterflood-supported lease has a longer, flatter decline than a primary well, and pattern realignment or a new injector can lift a lease years after it looked finished. Kansas has also studied carbon dioxide flooding in comparable Central Kansas Uplift reservoirs.
Chase-Silica royalty interests are usually small, old and split many ways, which is precisely what makes them awkward to value with a rule of thumb. A flat multiple of last month’s check ignores whether the lease sits inside an active injection pattern, whether the operator is a committed waterflood operator, and whether the interest carries both Arbuckle and Lansing-Kansas City pay. We underwrite by recovery method and by lease, not by a blanket per-acre number. Pointer Minerals is a direct buyer — we buy minerals and royalties in Rice, Barton and Stafford counties and provide free written offers.
County-level well data, production charts, and selling guides for the counties this field spans:
Often yes. Kansas stripper leases produce modest volumes per well, but waterflood support means those volumes can persist for a very long time. Value here comes from duration and from how many wells and zones your tract is charged with, not from a big monthly number. Small, long-lived Central Kansas Uplift interests trade regularly, and a written offer costs you nothing to obtain.
It matters a great deal. A unitized or pattern waterflood behaves differently from a primary well: decline is flatter, the operator has capital committed to injection, and pattern changes can raise production years down the road. It also means your interest may be pooled into a unit where you share in unit production rather than in specific wells. We read the unit and lease terms before pricing.
Yes. Undivided mineral and royalty fractions are sold independently every day, without the consent of your co-owners. What matters is establishing a clean chain of title from the record owner to you, which usually means probate or affidavit-of-heirship documents. We are used to working through Kansas heirship records and will tell you plainly what is needed before closing.
