Development

Goliat is a field in the Barents Sea, 50 kilometres southeast of the Snøhvit field. The water depth is 360-420 metres. Goliat was discovered in 2000, and the plan for development and operation (PDO) was approved in 2009. The field is developed with a cylindrical floating production, storage and offloading facility (Sevan 1000 FPSO). Eight subsea templates with a total of 32 well slots are tied-back to the FPSO. Production started in 2016. Goliat was granted a PDO exemption for the Snadd reservoir in 2017 and production started the same year.

Reservoir

Goliat produces oil from sandstone of Triassic age in the Kobbe and Snadd Formations, and in the Kapp Toscana Group (Realgrunnen subgroup) of Triassic to Jurassic age. The reservoirs have thin gas caps and lie in a complex and segmented structure at depths of 1,100-1,800 metres.

Recovery

The field is produced using water injection as pressure support. Additional pressure support results from reinjection of produced gas.

Transport

The oil is offloaded to shuttle tankers for transport to the market. Future gas export is pending an export solution.

Status

Production regularity has been below expectation since production start-up. Continuous maintenance and modification work along with several revision stops have resulted in a gradually improved regularity of the facility. In 2018, production from two new infill wells started. Drilling of the Goliat Vest prospect in 2018 resulted in additional resources. More infill wells and exploration wells are planned.
