Lower Tertiary Well Benchmarking

Cross-field well performance benchmarking (2010–latest).

Provenance. Derived deterministically from BSEE OGOR-A production across the Lower-Tertiary fields; same frozen data window as the V30 economics.

Data limits & honest caveats

Benchmarks reflect only wells with reported OGOR-A production; wells absent from the structured data are excluded rather than estimated.

#Lower Tertiary Well Benchmarking

Play: Lower Tertiary · Fields: all producing fields · Spud window: 2010–latest · Data through: 2026-04-30 (BSEE OGOR-A)

Per-well benchmark for 56 producing wells, sorted by cumulative oil. Drilling/completion timing and interventions are derived from BSEE WAR + V30 drilling data; first oil, cumulative oil and uptime from OGOR-A production; decline (D, EUR) from the forecasting module; estimated revenue from monthly oil × the historical WTI deck. Cells shown as are not derivable from the public data for that well (flagged, not fabricated).

#Data flags

Wells where a metric could not be fully derived from public BSEE data (the value is computed on what is present and flagged here):


Deterministic: same config + same BSEE data → identical table. Regenerate with uv run python scripts/lower_tertiary/build_well_benchmark.py --config config/input/lt_well_benchmark.yml.
