OPEC strongly encourages her members to assert their authority over their national assets through introduction of effective policies and application of efficient information technology in the monitoring and control of the upstream sector.

All companies presented net volume balances, and most companies presented gross liquid balances (including water and losses). However, it proved difficult to determine the reliability of the gross balances A suitable information system mainstreamed into the companies’ information and reporting systems, needs to be established to provide the mass balance data on a routine basis, without resorting to ad hoc exercises. . 1. 2 Royaltie s/ PPT Volumes used by the companies for Royalty and PPT were reconciled between the hydrocarbon flows and the taxation and royalty returns. The position, however, is very complex due to the arrangements for unitisation and product swaps between companies. Some company data differed from the mass balance. ACTIONS TAKEN Each company should submit an annual statement to DPR and FIRS reconciling its PPT and royalty self assessments to the annual mass balance and DPR guidelines (to be prepared).
