Turner
Sandstone

The Turner Sandstone is a Late Cretaceous marine sandstone and one of the principal horizontal oil targets in the deep Powder River Basin of northeastern Wyoming. It is developed across Converse, Campbell, and Johnson counties, and it is among the formation names mineral owners in the basin most often see on their wells.

Therocks beneath your minerals.

The Turner is a sandstone interval within the broader Frontier Formation, equivalent to what is called the Wall Creek in some areas. It was deposited as marine sand bodies that now form a tight reservoir, productive through horizontal drilling and modern completions.

In the deep part of the basin the Turner commonly falls between roughly 11,000 and 13,500 feet. It sits within a stacked sequence of Cretaceous targets, with the Niobrara above it and the Mowry below, so its depth and quality vary with position in the basin.

Because these targets are stacked vertically, a single tract can host wells in more than one of them, developed over different phases of basin activity.

Where theproduction lives.

Horizontal Turner development has been a steady part of the deep Powder River Basin oil story. EOG Resources and Devon Energy are among the operators that have carried the Turner in their basin inventory, alongside the Niobrara and the other stacked targets.

Turner wells produce oil with associated natural gas, with results strongest in the more thermally mature parts of the deep basin. Development in Wyoming is governed by the Wyoming Oil and Gas Conservation Commission, which handles spacing and the pooling process that assembles a drilling unit.

The current operator and completed formation on any specific well can be confirmed through the Commission’s public well records.

Mineral rights in theTurner.

Mineral owners in the deep Powder River Basin commonly see Turner wells on their tracts, often alongside Niobrara and Mowry wells in the same area. A single drilling unit can generate staged royalty income as the different stacked layers are developed over time.

For inheritors with Powder River minerals, knowing whether your wells are completed in the Turner, the Niobrara, or the Mowry helps explain what you are receiving and why one tract can carry several producing interests.

Lease terms and pooling elections across Wyoming vary by vintage and by tract, and that language can affect net royalty income beyond what the well data alone would suggest. We are happy to walk through what your specific situation looks like alongside the public well records, on a call or by email.
