Cravo

Location and Geology

• The Cravo field is situated approximately 140 km offshore Angola, in water depths ranging between 1,100 and 1,400 meters.
• The field is part of Block 17, which is operated by TotalEnergies.

Discovery and Development

• The Cravo field was discovered in 1999, along with the Orquidea field. Lirio was discovered in 1998, and Violeta in 2001.
• The development of the Cravo field, along with the other three fields, was approved in August 2010. Production started in June 2014.

Production and Reservoirs

• The Cravo field, along with Lirio, forms one of the two production hubs within the CLOV project, known as the Cravo/Lirio hub. This hub produces oil from Oligocene reservoirs.
• The Oligocene reservoirs in the Cravo and Lirio fields produce crude oil with an API gravity of 32-35°, which is one of the best qualities in Block 17.

Infrastructure and Operations

• The CLOV project, including the Cravo field, involves 34 subsea wells (19 producers and 15 water injectors) tied back to the CLOV floating production, storage, and offloading (FPSO) unit.
• The FPSO vessel, built by Daewoo Shipbuilding & Marine Engineering (DSME), has a production capacity of 160,000 barrels of crude oil per day and a gas treatment capacity of 6.5 million cubic meters per day. It also has an oil storage capacity of 1.78 million barrels.
• The project includes a multi-phase pump system, eight production manifolds, and a 211 km-long subsea pipeline network. Subsea7 installed the subsea pipelines and other subsea infrastructure.

Phase Two Development

• The CLOV Phase Two project, launched in 2018, involves the drilling of seven additional wells and ties back to the existing CLOV FPSO. This phase targets an additional 55 million barrels of oil equivalent (boe) resources and is expected to reach a production rate of 40,000 boe per day by mid-2022.

Partners and Contractors

• TotalEnergies operates Block 17 with a 38% interest. Other partners include Equinor (22.16%), ExxonMobil (19%), BP Exploration Angola (15.84%), and Sonangol P&P (5%).
• Various contractors were involved in the project, including GE Oil & Gas for gas turbines and compressors, Technip for umbilicals, and FMC Technologies for subsea production equipment.

Environmental and Operational Efficiency

• The project is designed to ensure 'zero flaring' under normal operations, with gas either exported to an onshore liquefaction plant or used to support other Block 17 operations.
• The use of an all-electric subsea multi-phase approach and other innovative technologies aims to improve recovery and operational efficiency.

The Cravo field, as part of the CLOV project, represents a significant deepwater oil development in Angola, leveraging advanced technologies to optimize production and environmental performance.
