Hurricane completes flow tests in Lancaster early production system

Hurricane Energy Plc has completed a prolonged individual flow test of 205/21a-6 in the early production system (EPS) on Lancaster field in the West of Shetland area offshore UK at the end of January, then reverted to producing both wells 205/21a-6 and 205/21a-7Z at increasing rates in February.

The combined production rate was increased in March to 20,000 b/d comprising 12,000 b/d from 205/21a-6 and 8,000 b/d from 205/21a-7Z, before downtime.

The rates contain about 6,000 b/d of water, predominantly from 205/21a-7Z. Overall water cut for the quarter was 17%, well within the capacity of the Aoka Mizu FPSO water handling facilities.

Rates have been achieved without the use of electrical submersible pumps and with wells choked back to less than 50%, confirming the high productivity of the wells and reservoir.

As at the end of March, the EPS has produced 4.4 million bbl of oil since starting up last year. Still in the data gathering phase, further testing at current rates will be required before trends can be confirmed and conclusions made about the long-term behaviour of the reservoir.

Once trends have been established, alternative combinations of well rates may be tested to establish optimum long-term production from the two wells.
