API 35-051-24817 · OK · Drilled 1981 · 6,240 ft TD · Status: Marginal

Viability Score

Recommended Development Pathway

Workover + Recompletion

Estimated Incremental Recovery

5–9K bbl

Low-cost recompletion targeting bypassed Tonkawa pay. Modest recovery but low capital requirement — strong payout economics.

Six-Driver Viability Assessment · Avg 72/100

Reservoir Potential

72/100

Bypassed pay identified in upper Tonkawa interval — not perforated on original completion. Log analysis confirms 14 ft of net pay.

Wellbore Condition

78/100

Good casing integrity. Existing perforations in lower zone can be isolated with a retrievable bridge plug.

Field Redevelopment

68/100

Isolated well, no nearby offset production in Tonkawa. Development risk is single-well.

Infrastructure Readiness

74/100

2.9 miles to gathering. Active tank battery on lease — minimal surface work required.

Regulatory Clarity

71/100

Active lease, operator current. Standard recompletion permit, 30-day processing typical.

Environmental Profile

69/100

No environmental issues on record. Low methane profile.
