Oil and gas explorer Hurricane Energy has successfully produced oil from its Lancaster well west of Shetland, a remote area between Scotland and the Faroe islands which holds a fifth of Britain's untapped oil and gas resources.
Hurricane, which listed on London's Alternative Investment Market (AIM) in February, said on Thursday production tests using a pump achieved a flow rate of 9,800 barrels of oil per day, well above expectations.
"I am delighted to report the successful completion of our testing operations which have achieved hydrocarbon flow rates in the upper range of our pre-drill estimates," said chief executive Robert Trice in a statement.
Hurricane specialises in drilling for oil in basement reservoirs, lying beneath the sandstones typically targeted by oil and gas explorers.
Its successful oil flow tests add to Britain's prospects of tapping new oil and gas reserves in the challenging area West of Shetland, which has strong winds and waves and is very deep.
Hurricane, which fully owns the Lancaster well, has suspended the project while it is analysing the data collected during testing.
"This looks to be a good result and we think it should help the company to find a partner if this is the plan," said analysts at Canaccord.
