Turkish Petroleum has let a contract to Schlumberger and Subsea 7, as part of a consortium, for the engineering, procurement, construction, and installation (EPCI) of end-to-end production solutions for Sakarya gas field, offshore Turkey.
The integrated project scope will cover subsurface solutions to onshore production, including well completions, subsea production systems (SPS), subsea umbilicals, risers, flowlines (SURF), and an early production facility (EPF).
Schlumberger will deliver the well completions scope and the design, construction, and commissioning of the early production facility capable of handling up to 350 MMscfd of gas. The SPS and SURF scope will be delivered by OneSubsea, the subsea technologies, production, and processing systems division of Schlumberger, and Subsea 7.
The scope of work to be executed by Subsea 7 comprises the EPCI of the subsea pipelines and associated equipment to connect the subsea wells in about 2,000 m water depth to the EPF. The project includes the provision and installation of infield flowlines, control umbilicals, tie-in connections, associated subsea equipment, 170 km of gas export pipeline and monoethylene glycol injection pipeline to the EPF.
Project management and engineering have begun and will be managed from Istanbul.
Subsea 7 values revenue share of the contract over $750 million.
Sakarya is the largest gas reserve ever discovered in Turkey. The subsea development will lie about 100 nautical miles into the Black Sea.
