In Salah – In Salah Gas is a joint venture between BP (33 percent), Sonatrach (35 percent) and Statoil (32 percent). The project comprises a phased development of eight gas fields located in the Ahnet-Timimoun Basin in Algerian Central Sahara. The initial development focuses on the exploitation of the gas reserves in the three northern fields. These gas fields contain CO2 concentrations ranging from one to nine percent, which is above the export gas specification of percent and, therefore, requires CO2 removal facilities. Instead of venting the CO2 to the atmosphere, In Salah Gas re-injects the produced CO2 (up to 70 million scfd or million tonnes per year) into the aquifer.
