Abstract
A large percentage of the oil and gas production around the world today comes from mature hydrocarbon reservoirs. In turn, these mature assets supply the bulk of the world's energy. In Nigeria, most of these assets are situated in volatile environments. Managing these assets is therefore a pivotal aspect of ensuring Nigeria meets its OPEC energy supply obligation.
Strategic Reservoir Management (SRM) is a robust integrated production restoration and optimization approach that seeks to drive value from existing assets by ensuring economical/optimal and safe evacuation of hydrocarbon from the reservoir to surface tanks. The BNT Field Management Team seeks to leverage on SRM best practices to identify Short Term and Long-Term opportunities that will enable the asset to achieve its oil and gas production aspirations and enable Nigeria to continue to fulfil its oil and gas production obligation.
Some of the BNT field's most productive oil and gas reservoirs are the prolific X1000A and Y9500A reservoirs. Many third-party interferences with flowlines and difficulties with asset integrity have significantly delayed output from the oil conduits and reduced value. Based on the outcome of an integrated well, reservoir and facility review and candidate selection process, BNT002 well was chosen as the first well to be restored to production. This paper presents an integrated approach for the restoration and optimization of a surface comingled oil well to add ca. 4.15 Mbopd and develop ca. 6.00 MMstb. BNT hydrocarbon streams are evacuated via two facilities – BN NAG Plant (450 MMscf/d capacity for gas and a liquid handling capacity of 10 Mbbl/d) and BN flow station (30 Mbpd capacity).
