McDermott International Inc. has completed Phase 1 of the deepwater Atlanta Early Production System for independent Brazilian exploration and production company Queiroz Galvao Exploracao e Producao SA (QGEP). Atlanta field lies in Santos basin on Block BS-4 in about 5,000 ft of water.

The system includes project management, engineering, and installation of subsea hardware for subsea umbilicals, risers, and flowlines. The project is 115 miles southeast of Rio de Janeiro.

McDermott’s North Ocean 102 handled the umbilical installation scope while a third-party vessel, the Skandi Niteroi, handled the flexible installation.

The early production system (EPS) consists of a dedicated floating production, storage, and offloading vessel with a single-point mooring turret that connects to three wells (2HP and 3H already drilled and 4HA to be drilled late 2018 or early 2019).

The system is equipped with horizontal wet christmas trees with individual vertical flowline connections.

EPS production is estimated to reach 20,000 b/d with the commissioning of the first two wells and is expected to increase to 30,000 b/d with the commissioning of the third well.

A definitive production phase, scheduled to start in 2021, will integrate a larger FPSO with a processing capacity of 80,000 b/d and development of as many as nine additional horizontal wells.

QGEP holds 30% interest and is the operator of Block BS-4. Other Atlanta partners include Dommo Energia 40% and Barra Energia 30%.
