Smackover · Arkla Basin

API 05-069-20156 · AR · Drilled 1971 · 10,120 ft TD · Status: Marginal

Viability Score

Recommended Development Pathway

Enhanced Recovery — Waterflood

Estimated Incremental Recovery

8–14K bbl

Marginal producer recoverable through waterflood optimization. Elevated water cut manageable with SWD upgrade.

Six-Driver Viability Assessment · Avg 79/100

Reservoir Potential

80/100

Pressure depletion evident. Waterflood pattern from adjacent operator suggests pressure support available.

Wellbore Condition

75/100

Minor casing corrosion at 6,200 ft. Repairable. Cement bond acceptable above production interval.

Field Redevelopment

82/100

3-well waterflood pattern feasible. Injection well conversion identified 0.4 miles NW.

Infrastructure Readiness

78/100

3.8 miles to gathering. Water handling infrastructure in place on adjacent lease.

Regulatory Clarity

85/100

Operator active. Injection permit pathway clear — similar pattern approved in county 2022.

Environmental Profile

72/100

Low-level methane plume detected upwind. Workover will address. No surface contamination on record.
