In a meeting with Libya’s state oil company National Oil Corp. (NOC), Descalzi and NOC CEO Mustafa Sanalla discussed the Bahr Essalam Phase II development, which includes the completion of 10 wells. Nine of the 10 wells were drilled in 2016 at the field, which is one of the largest reservoirs in Libya. First gas is set for 2018.

The Bahr Essalam field is in Block NC 41 in the central Mediterranean Sea. Plans for Phase II of the development include a tieback to the Sabratha platform, which is some 110km off the Libyan coast in about 190m water depth.

The natural gas field development is operated by Mellitah Oil & Gas, a consortium between NOC and Eni North Africa.

According to Mellitah, the reservoir rock at Bahr Essalam is composed of carbonate facies, and the petrophysical characteristics are generally good, especially in the most productive upper zone. The gas and condensate are produced from 15 platform wells and 11 subsea wells divided in two clusters located 20 and 25km away from Sabratha platform.

The production from the subsea and platform wells is treated on Sabratha platform for separation and dehydration. The condensate is pumped through a 10in pipeline to Mellitah for further treatment and export. The gas is transported through a 36in pipeline to the Mellitah plant for final treatment and onward transmission to the local market and export to Italy through the Green Stream compression station and 540km 32in sea line, says Mellitah.

The Sabratha platform is considered to be one of the biggest Libyan offshore oil and gas facilities, says Mellitah. It is fixed to the seabed in 190m water depth. The platform consists of all the facilities required for preliminary separation and treatment of the gas produced from Bahr Essalm field as well as a fast-moving workover rig, living quarters for 117 persons and a helideck.

In June 2016, TechnipFMC (formerly Technip) was awarded the contract to develop the second phase of the project that will include the overall design, detailed engineering and deliver the project management, as well as procurement, installation, tie-ins, pre-commissioning and commissioning.

At the time, Technip said that offshore installation was scheduled for 2H 2017 through 2H 2018. A range of vessels from the group’s fleet will be involved, including Deep Energy pipelay vessel, Deep Arctic diving support vessel, and G1200 s-lay vessel.
