The Miocene sands shows up in state oil and gas commission well records as a producing formation or pool in 22 of the counties and parishes we cover, across the Gulf Coast Basin. Every county where it produces sits in the same basin, though well counts and operators differ county to county. Across those counties, state records show 3,152 active wells producing, with the heaviest activity in Plaquemines Parish, Lafourche Parish, Acadia Parish. 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 Miocene sands play
These are the counties and parishes we cover where state commission records show the Miocene sands producing. Each links to that county's own Miocene sands well count and operators, not just the general county page.
What the Miocene sands 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.

The Miocene sands is part of the Gulf Coast Basin. For the basin-wide value bands and the counties we buy in, see the Gulf Coast Basin page.
Miocene sands questions
- Which counties does the Miocene sands produce in?
- State commission well records show the Miocene sands producing in 22 counties we cover: Acadia Parish, Assumption Parish, Calcasieu Parish, Cameron Parish, East Baton Rouge Parish, Evangeline Parish, Iberia Parish, Iberville Parish, Jefferson Davis Parish, Jefferson Parish, Lafayette Parish, Lafourche Parish, and others. See each county's page for the full local well and operator picture.
- How many wells produce from the Miocene sands?
- Across the counties we cover, state oil and gas commission records show about 3,152 active wells tied to the Miocene sands. That figure is a sum across counties from public well records, not a measure of any one owner's interest.
- What is a Miocene sands mineral interest worth?
- A Miocene sands 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.
