PetroSA (Mossgas) E-M Mossel Bay

PetroSA E_M Mossel Bay

South Africa Block 9

Landmark: Control systems using radio signals from beach to buoy

The E-M Mossel Bay gas field is situated 74 miles (120 km) southwest of the Mossel Bay complex. The field lies in the Bredasdorp Basin Block 9 and was discovered in 1984, when the well tested 10 mmcf/d. The development consists of production wells tied back by an 18” pipeline to the Mossgas production platform, on the FA field 3 miles (5 km) to the east. Production is managed by a control buoy.

The field has been developed by the Bredasdorp Alliance between the owner, Mossgas, and the managing contractor, Dresser Kellogg. The project first delivered gas to the onshore plant in April 2000 and will supply feedstock until 2007. The project involved the drilling of seven subsea wells in the Mossgas field. A single dual-lateral well was drilled into the EBF field immediately after the first two wells. The first phase was completed in April 2000, and the second phase was completed in 2001.
