GODALMING, UK – Hurricane Energy has issued an update on the extended production test that is assessing deliverability from the basement Lancaster oil field west of Shetland.
During 4Q 2019 facilities availability of over 90% allowed the company to initiate individual well flow tests.
These have been designed to determine individual well performance and the optimum combined well flow rate, given strong pressure communication between the wells.
In 4Q the 205/21a-7Z well produced on its own for 25 days, including periods at relatively low rates (as part of the reservoir evaluation process). This led to lower oil production and a higher average water cut than observed during the start-up period in 3Q.
The Lancaster 6 well flowed on average 12,500 b/d for nine weeks during the individual well flow period until the latest (eighth) lifting of crude from the FPSO Aoka Mizu last Wednesday.
After completing the test on the 6 well, this will be flowed with 7Z at a combined rate of roughly 20,000 b/d.
Hurricane is also considering drilling an additional Lancaster producer later this year to fully use the FPSO’s throughput capacity and to provide dynamic data from another part of the Lancaster reservoir.
