The Mississippian shows up in state oil and gas commission well records as a producing formation or pool in 38 of the counties and parishes we cover, across the Cherokee Basin, Sedgwick Basin and Central Kansas Uplift. It is not confined to one basin; owners in different basins hold Mississippian interests that are valued the same way, on the income the wells actually pay. Across those counties, state records show 90,252 active wells producing, with the heaviest activity in Woodson County, Allen County, Miami County. This page is built from the same public well-record data as our county pages, not a USGS geologic assessment, so it does not carry a play-wide resource estimate the way our larger flagship formation pages do.

Counties in the Mississippian play

These are the counties and parishes we cover where state commission records show the Mississippian producing. Each links to that county's own Mississippian well count and operators, not just the general county page.

What the Mississippian means for your minerals

A resource estimate for a play is not the value of your acreage. Your mineral and royalty interest is valued on the income your wells actually pay, roughly 36 to 72 times your average monthly royalty check, the same as 3 to 6 times your annual royalty. Where you land in that band depends on your wells decline, the operator, your royalty rate, and any undeveloped drilling upside. For the full method and a free on-screen estimate, see what are my mineral rights worth.

The Mississippian is not confined to one basin: state records show it producing across Cherokee Basin , Sedgwick Basin , and Central Kansas Uplift . For the basin-wide value bands and the counties we buy in, see each basin's page.

Mississippian questions

Which counties does the Mississippian produce in?

State commission well records show the Mississippian producing in 38 counties we cover: Allen County, Anderson County, Barber County, Barton County, Butler County, Chautauqua County, Cheyenne County, Coffey County, Comanche County, Cowley County, Elk County, Ellis County, and others. See each county's page for the full local well and operator picture.

How many wells produce from the Mississippian?

Across the counties we cover, state oil and gas commission records show about 90,252 active wells tied to the Mississippian. That figure is a sum across counties from public well records, not a measure of any one owner's interest.

What is a Mississippian mineral interest worth?

A Mississippian interest is valued the same way as any producing interest: roughly 36 to 72 times your average monthly royalty check. Where you land in that range depends on your wells' decline, the operator, your royalty rate, and any undeveloped drilling upside. This is an estimate, not an offer.
