Petroleum Safety Authority (PSA) has given ExxonMobil a consent to use Island Frontier and Island Wellserver for light well intervention (LWI) at Sigyn.
The Sigyn field is located west of Stavanger in production licence 072, where ExxonMobil Exploration and Production Norway AS (ExxonMobil) is the operator. The field contains gas, condensate and light oil.
Sigyn has been developed using a subsea well template. The well stream is transported to the Sleipner A facility 12 kilometers north-west of the well template.
ExxonMobil has received consent to use the two mobile drilling facilities Island Frontier and Island Wellserver for undertaking light well intervention at Sigyn. The activities are scheduled to start in August and last to the end of 2016.
It is provisionally uncertain as to which facility will be used for the well intervention, since this depends on optimizing the work schedules for the two facilities, PSA noted.
The period may also be extended into 2017 if the availability of the facilities so dictates.
The two facilities are owned by Island Offshore.
