Royal Dutch Shell Plc (RDSA), operator of Nigeria’s largest oil fields, agreed to invest about $4 billion with its partners in two oil and gas projects in the country.

The Shell Petroleum Development Co. of Nigeria, which Shell operates as a venture with Eni SpA (ENI), Total SA (FP) and the government, according to Bloomberg, will develop the Forcados-Yokri project and the Southern Swamp associated gas gathering project, the company said today in a statement. The projects are expected to pump 100,000 barrels and 85,000 barrels of oil equivalent a day at peak, respectively.

Southern Swamp will “collect gas, reduce flaring, while there is associated oil production and it will produce gas for domestic use for power,” Chief Financial Officer Simon Henry told reporters today in London. Both of the projects “are very strategic” for Nigeria. The Forcados-Yokri fields are located in shallow waters in the west of the country.

Shell, based in The Hague, last month said it planned to invest about $3.5 billion in a natural-gas project in Imo state in the southeast. It is working on 17 gas projects in Nigeria, set to cost a total of $6 billion, according to the company.
