Marble Falls Limestone Mineral Rights — Pennsylvanian Carbonate Geology Guide

What Is the Marble Falls Limestone?

The Marble Falls Limestone is a Pennsylvanian-age carbonate formation that’s the leading productive reservoir in Eastland County, Texas. It produces from 7 of the top 20 individual wells in the county. The formation is named after Marble Falls, TX (Burnet County, central Texas) where it was first described.

In the Bend Arch / Eastland County area, the Marble Falls sits within the broader Pennsylvanian sequence below the Caddo Limestone and above (or interfingering with) the Strawn Group sandstones.

Age: Pennsylvanian (Carboniferous, ~315 million years old)

Lithology: Limestone (carbonate) with localized chert and dolomite

Typical depth: 2,800-4,000 ft TVD in Eastland / Stephens / Palo Pinto counties

Porosity: 6-12% (moderate; lower than the overlying Caddo)

Permeability: low matrix; fracture-enhanced effective permeability

Marble Falls in Eastland County

The Marble Falls is the leading formation in Eastland County’s top 20 individual wells:

Sneed, Ernest 1 — #4, 176 bbl/mo (Ronning Gas & Oil)

Hanvey-Fee "E" 12 — #7, 141 bbl/mo (Hanvey Don H Oil Interests)

Miller, Conrad & Cecil 4 — #13, 97 bbl/mo (Ronning)

Miller, Conrad & Cecil 6 — #15, 97 bbl/mo (Ronning)

Conrad & Cecil Miller 5 — #16, 94 bbl/mo (Ronning)

Walker, Monroe 3 — #19, 84 bbl/mo (Lowrance, Top Marble Falls completion)

Note the operator concentration: Ronning Gas & Oil holds 4 of the top Marble Falls producers, all on Miller / Conrad / Cecil family-name leases in the southern part of the county.

Production Profile

Marble Falls Limestone wells produce primarily oil with limited associated gas. Modern production is dominated by long-life waterflood operations:

Per-well rate: 1-5 BOPD typical (stripper economics)

Decline rate: 4-8% annual on mature waterflood

Reserve life: 10-25 years on actively-maintained units

Variability: Marble Falls reservoir character is heterogeneous; localized fracture networks create production sweet spots, while adjacent wells in the same lease may be near-zero producers
