The In Amenas development will span four production fields covering an area of more than 2,750sq.km. The first phase will include the development of the Tiguentourine gas field, 50km southwest of In Amenas.

The engineering, procurement and construction contract will involve gas processing facilities, product pipelines and other infrastructure such as roads, accommodations and offices.

Pipeline-grade gas, liquefied petroleum gases and condensate products will be pipelined 110km for delivery to Sonatrach's pipeline grid at Ohanet.

Engineering will be executed from London by an integrated team. Total project duration up to performance testing is about three years.
