Nigeria’s crude oil output has risen significantly by 50, 000 barrels per day as Shell brings its third phase of Bonga field development to production.
Shell declared yesterday that its local deepwater affiliate, Shell Nigeria Exploration and Production (SNEPCO) bought third development project at the Bonga field on stream with production profile of 50, 000 barrels of oil equivalent per day (boe/d).
The new output from Bonga III operated by Shell as appendix to the deep-water Bonga Main field pushes output from Nigeria’s deep-water satellite fields to 180, 000 b/d The start-up of Bonga III would also mark the third deepwater development project to come online in quick succession after Bonga North West also by Shell and Erha North II operated by ExxonMobil’s local deepwater affiliate, Esso Exploration and Production Nigeria Limited (EPNL).
Together, the three satellite field developments increase Nigeria’s oil production from the deep offshore terrains by 180, 000 barrels per day (180 kbd). Oil from the Bonga North West sub-sea facilities is transported by a new undersea pipeline to the existing Bonga floating production, storage and offloading (FPSO) export facility.
The Bonga FPSO has been upgraded to handle the additional oil flow from Bonga North West which, at peak production, is expected to contribute 40,000 barrels of oil equivalent per day, helping to maintain the facility’s overall output. Four oil producing wells and two water injection wells in the Bonga North West development will be connected to the FPSO, from where oil is loaded onto tankers for shipping around the world.
The ExxonMobil’s Erha North II project is a deepwater subsea development located 60 miles offshore Nigeria in 3,300 feet of water and four miles north of the Erha field, which has been producing since 2006.
The Erha North II project includes seven wells from three drill centres tied back to the existing Erha North floating production, storage and offloading vessel, reducing additional infrastructure requirements.
The project is estimated to develop an additional 165 million barrels from the currently producing Erha North field. Peak production from the expansion is currently estimated at 65,000 barrels of oil per day and will increase total Erha North field production to approximately 90,000 barrels per day.
