Bonga Phase 3 is an expansion of the Bonga Main development, in OMG 118. The Bonga field is located approximately 120km off the coast of Nigeria in the Gulf of Guinea at 1000m water depth.
Production will be transported through existing pipelines to the Bonga floating production storage and offloading (FPSO) facility, which has the capacity to produce more than 200,000 bbl and 150 MMcft/d of gas, Shell said.
The Bonga field, which began producing oil and gas in 2005, was Nigeria’s first deepwater development in depths of more than 1000m. To date, Bonga has produced more than 600 MMbbl.
Shell began production from Bonga North West in August 2014. All six wells, four oil producing and two water injection wells have been completed and are onstream. They are contributing more than 40,000 boe/d at peak annual production, which is transported by a new undersea pipeline to the upgraded Bonga FPSO.
According to Shell, the project included upgrading the Bonga FPSO to add new chemical injection systems to prevent corrosion and freezing in the new pipelines. The 300m long FPSO is one of the largest of its kind in the world, held in place by 500-tonne anchors linked by 20km of mooring lines. It receives crude from production wells on the seabed. The oil is processed on board, stored and then sent to a single point mooring buoy anchored nearby from where it is loaded onto tankers for export. Below the surface a new production module was tied into the existing infrastructure.
The Bonga project is operated by Shell Nigeria E&P Co (SNEPCo) with 55% interest as contractor under a production sharing contract with the Nigerian National Petroleum Co., which holds the lease for OML 118.
Partners include Esso E&P Nigeria Ltd. (20%), Total E&P Nigeria Ltd. (12.5%) and Nigerian Agip Exploration Ltd. (12.5%).
