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 the Goliat West segment in 2020. The production from these accumulations started in 2017 and 2021, respectively.

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 are in a complex and segmented structure at depths of 1100-1800 metres.

Recovery strategy

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 planned via the Snøhvit pipeline to the liquid natural gas (LNG) processing facility at Melkøya near Hammerfest.

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. A solution for Goliat gas export is being considered, which will contribute to extend the lifetime of the field. Several infill wells have been drilled since start up. In 2021 and 2023, the discoveries 7122/6-3 S (Rødhette) and 7122/8-1 S (Countach) were made in the area north of the Goliat field. More infill and exploration wells are planned in the coming years.
