Caddo Formation Mineral Rights — Pennsylvanian Carbonate Geology Guide

What Is the Caddo Limestone?

The Caddo Limestone is a Pennsylvanian-age carbonate formation that’s the dominant producing reservoir across the Bend Arch region of north-central Texas. It’s named after Caddo, Texas (Stephens County), where it was first identified as a productive interval during the 1917-1921 Breckenridge oil boom.

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

Lithology: Limestone (carbonate) with localized sandstone interbeds

Typical depth: 2,800-3,500 ft TVD across the Bend Arch

Porosity: 8-15% (moderate)

Permeability: low matrix; fracture-enhanced effective permeability

Caddo Sub-Intervals

The Caddo is informally divided into several sub-intervals across the Bend Arch:

Caddo (main) — the primary producing interval; ~2,800-3,200 ft TVD

Caddo A — an upper sub-zone, often a separate completion interval

Caddo Disposal — deeper Caddo interval increasingly accessed via 2014-2018 directional re-entry programs (BASA Resources’ Stephens County campaign)

Production Profile

Caddo wells produce primarily oil with limited associated gas. Modern Caddo production is dominated by long-life waterflood operations with the following characteristics:

Per-well rate: 2-5 BOPD typical (stripper economics)

Decline rate: 3-7% annual on mature waterflood

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

Modern enhancement: directional re-entries into Caddo Disposal interval (2014-2018 vintage; can deliver 800-2,100 bbl/month per well in best cases)

Counties Where the Caddo Produces

The Caddo Limestone is the dominant producing formation across the following Bend Arch counties:

Stephens County — the productive heart of the Caddo trend

Eastland County

Palo Pinto County

Young County

Shackelford County

Throckmorton County
