On 29 October 2018 Sonatrach, BP and Equinor reportedly signed an agreement for the development of unconventional hydrocarbon resourcesÂ  in the south-west of the country. This agreement builds on a study about unconventional gas resources completed by Sonatrach and BP in 2013. The work program proposed by BP and Equinor is viewed as promising by Sonatrach, it includes the acquisition of 3D seismic and the drilling of several exploration and appraisal wells.  In the medium term this project could maintain plateau production at currently operating fields and extend the life of a large existing surface infrastructure put in place by BP and Equinor. Both companies are partners in the In Salah gas project, Timimoun Basin, south-west of Algeria.   In late2016, the southern fields of the In Salah Gas (ISG) phase 2 field development project came on stream. This increased the overall gas production of In Salah by 141 MMcf/d to around 900 MMcf/d.  In February 2016, BP announced that the ISG phase 2 project started production. The phase 2 production will allow to maintain the plateau production of the whole In Salah project at 9 Bcm/y (318 Bcf/y) as the initial three northern fields see their production decline. The incremental gas production from the ISG phase 2 will be 500 MMcf/d once ramp-up of the project is complete.   The fields involved in the ISG project are Krechba, Teguentour and Reg of the phase 1 in the north and Garet El Befinat, In Salah, Hassi Moumene and Gour Mahmoud of the phase 2 in the south. The gas from the ISG project is exported since 2004 to Europe.  Participants in the ISG are: BP North Africa,Â  operator with 33.15%, Statoil with 31.85% and Sonatrach with 35%.
