The problems that show up at close, in the dispute, and at the berth.

Balances, allocation runs and period close happen in one place on one calendar. Closing stops being a three-week reconciliation between systems and becomes a review of exceptions.

When a partner challenges a volume, the allocation lineage shows the readings, the rules and the version of the run that produced it — instead of a rebuilt spreadsheet.

Entitlement by participating interest is computed from the same balance operations produced, so statements and settlement positions agree with the field record by construction.

Nominations are scheduled against real berth, tank and pipeline capacity with conflict detection, and laytime and demurrage are recorded against the lift as it happens.

Batch tracking with tank inventories at both ends turns line fill, gains and unexplained losses into a measured quantity rather than a residual.

Unit yields, blending and product movements close into the same balance, so downstream conversion is accounted for on the same terms as production.

Field readings, well tests and lab results are captured once at source. The spreadsheets that currently carry the balance stop being the system of record.

Reporting draws on closed, versioned periods with audit history behind them, so the same figures can be reissued and defended later.
