Development

Goliat is a field in the Barents Sea, 50 kilometres southeast of the Snøhvit field. The water depth in the area 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.

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- 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 associated gas into the reservoir.

Transport

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

Status

Production regularity was below expectation during the first 20 months of production. Continuous maintenance and modification work during two prolonged production stops in 2017 and 2018 resulted in gradually improved regularity of the FPSO. In 2017, production started from the Snadd reservoir. 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.
