Data Warehousing for Oil & Gas: Production, Reserves, and Commercial Data Unified

An operator builds a data warehouse and the production team doesn't trust it. The well count differs from production accounting because well status classification differs (producing vs shut-in vs abandoned). The production volumes differ because allocation methodology wasn't encoded. JIB calculations in the warehouse don't match what partners got billed because partner-specific allocation rules aren't represented. Reserves views don't tie to the 10-K SEC filing because the warehouse uses different downtime definitions. By quarter two, production is back to pulling data directly from P2 or Quorum for any important question, and the reserves team builds its own dataset for the annual filing. The warehouse investment doesn't pay back.

Oil and gas warehousing done right encodes production accounting semantics correctly from day one. Well master data with UWI, API, state IDs, and operator identifiers reconciled. Well status classification matching production accounting. Production volumes with the allocation methodology the operator uses (including partner-specific rules). AFE and JIB data with the full partner-operator distinction. LOE with cost categorization matching operations and finance. Reserves-aligned views with the same downtime, shrinkage, and allocation rules that feed reserves reporting. Commercial data with disposition-aware structure. Reconciliation to source systems after every load. Done with this discipline, the warehouse becomes the trusted source. Done generically, it stays parallel to the systems that actually own the data.
