Strawn Group Mineral Rights — Pennsylvanian Type Locality Geology Guide

What Is the Strawn Group?

The Strawn Group is a major Pennsylvanian-age sequence of sandstones, shales, and limestones in north-central Texas. The Group is named after the small town of Strawn, TX in Palo Pinto County, where it was first described — making the Strawn / Eastland / Palo Pinto area the type locality of the Strawn nomenclature used across the Bend Arch.

Age: Pennsylvanian (Carboniferous, ~310 million years old)

Lithology: Mixed sandstones, shales, limestones (clastic + carbonate sequence)

Typical depth: 2,500-4,500 ft TVD across the Bend Arch

Reservoir quality: variable; sandstone members can have good porosity (12-22%); limestone members lower

Trap mechanisms: stratigraphic pinchouts, low-relief structural anticlines, fractured carbonates

Where the Strawn Produces

The Strawn Group is productive across the Bend Arch trend of north-central Texas:

Eastland County — Strawn produces from 2 of top 20 wells, including the only modern 2017 directional well (Winchester 1)

Palo Pinto County — the type-locality area; significant Strawn production around Strawn and Mineral Wells

Stephens County — Strawn underlies the Caddo and contributes to deeper completions

Young, Shackelford, and Throckmorton counties — northern Bend Arch extension

Fort Worth Basin (eastern flank) — Strawn is one of multiple stacked Pennsylvanian targets, alongside the Barnett Shale beneath

Production Profile

Strawn Group wells produce primarily oil with limited associated gas:

Per-well rate: 5-25 BOPD typical for vertical Strawn completions; higher for modern directional wells

Decline rate: 8-15% annual on primary production; 5-10% on waterflood

Reserve life: 15-30+ years on actively-maintained units

Modern enhancement: selective directional re-entries (e.g. Winchester 1 in Eastland County, 2017) targeting deeper Strawn intervals
