Recommended Intervention Sequence
- 1M3H ESP retrofit + restartLowest-risk rate restoration. Gas-handler ESP with controlled restart.4–6 weeks · ~$385K illustrative capex
- 2M2H MIT + BHP surveyConfirm mechanical integrity and reservoir pressure before restart decision.2–3 weeks
- 3M2H restart / workover if mechanically cleanControlled restart with gas-handling mitigation.Gated on Step 2 results
- 4Protection protocol before OVERTON B completionWater cushion + shut-in window + offset-pressure monitoring.Pre-Jun 15
- 5Defer protection-refrac decisionOnly revisit after workover outcome and OVERTON B behavior are known.Deferred
Bolo prioritizes lowest-capital, fastest-rate-recovery action first. Higher-capital refrac decision is deferred until diagnostics confirm need.
M2H rate-decline event aligns with PANTHER E frac window
CriticalSCADA shows casing-pressure climb and field notes record failed ESP restarts; frac interference is the leading hypothesis, but mechanical and reservoir alternatives remain open.
Next action: BHP survey + MIT before any restart or refrac decision.
M3H restart attempts are gas-locking
HighField notes show repeated restart failures under higher-GOR conditions; gas-handler retrofit is the lowest-risk first intervention.
Next action: Approve ESP gas-handler retrofit and restart plan.
OVERTON B completion creates near-term protection window
CriticalPlanned completion within 1,800 ft creates parent-child risk for remaining producers.
Next action: Load water cushion 5–7 days pre-stim and assign offset monitor.
"Tried M2H restart again. Won't catch. Pump amperage flatlining. Calling it — leaving shut in."
"M3H gas locking on restart this morning. Pulled equipment for review. Same pattern as M2H."
"Second restart attempt M2H — gas locking under depleted draw. Casing pressure still climbing overnight."
"M2H casing pressure up overnight. Tried restart. ESP gas locking, unstable drawdown."
Casing pressure climbs as oil rate collapses; restart attempts coincide with field-note markers.
Cube tracks ~22% under Wolfcamp A analog; divergence widens after PANTHER E completion.
