Lifetime production
Production reconciliation
QAThe lifetime totals above come from BSEE's lease-level feed. Here we cross-check them against the independent OGOR-A well-level feed (summed across 5 wells · 5 completions). The two should track within a few percent; a large gap flags a keying or timing issue.
| Stream | OGOR-A (well-level) | Lease feed | Δ |
|---|---|---|---|
| Oil (BBL) | 21,167,584 | 21,808,894 | -2.9% |
| Gas (MCF) | 29,061,668 | 29,849,691 | -2.6% |
