Project Profile
Value: US$387.5 million
Location: 120km south-west of the Mossel Bay
Gas Capacity: 5.66 mcm per day
Start-up Year: April 2000
Reserves: 600 billion cubic feet of gas
The EM and satellite gas fields are situated 120km south-west of the Mossel Bay complex. They lie in the Bredasdorp Basin Block 9 and were discovered in 1984, when the well tested 10 million ft³/day in early Cretaceous sands. The porosity is typically 13% and permeability ranges from 5-200mD. Reserves are 600bcf. Development drilling is being carried out with the semisubmersible rig, South Seas Driller. The development consists of three new production wells, tied back by a 450mm (18in) pipeline to Mossgas\' production platform, on the FA field 49km to the east. Production is controlled by a buoy, overhead.
The field has been developed by the Bredasdorp Alliance between the owner, Mossgas, and the managing contractor, Dresser Kellogg. The US$387.5 million project first delivered gas to the onshore plant in April 2000. The new fields supplied Mossgas with feedstock until 2007. The two-phase project involves the drilling of up to five subsea wells into the EM field. A single dual lateral was drilled into the EBF field immediately after the first two EM wells. The first phase was completed in April 2000 and the second phase in 2001. In 2011, National oil company PetroSA received environmental approval to search for additional gas reserves off the coast of Mossel Bay. The Environmental Affairs Department this month approved PetroSA’s environmental-impact assessment for the exploration project, dubbed Project Ikhwezi, which aimed at extending the life of the Mossel Bay gas-to-liquids refinery. The wells are based off the F-O field located 40 km south-east of the F-A production platform. Production from the gas field is targeted for 2013.
