* First such success in British North Sea
* Hurricane shares hit two-year high
* Market awaits further data
ABERDEEN, Scotland, June 5 (Reuters) - Hurricane Energy has announced first oil at its Lancaster field off Scotland, the first such success for so-called fractured basement reservoirs in Britain and a major milestone for the company within its guided schedule.
Hurricane specialises in recovering oil from fractures in hard and brittle rock known as fractured basement reservoirs, which some see as a risky way to obtain crude.
“Lancaster is the UK’s first producing fractured basement field and the fact that Hurricane has delivered this industry milestone on time and within budget is an incredible achievement,” said Robert Trice, Hurricane chief executive.
Hurricane said that on Tuesday its Aoka Mizu floating production, storage and offloading vessel recorded 72 hours of output - a phase known as first oil - at a rate of 20,000 barrels per day.
Its shares were up around 2.7% at 60.65 pence by 0737 GMT on Wednesday, having hit a two-year high earlier.
“Today’s announcement from Hurricane is another step forward in demonstrating the scale and deliverability of the fractured basement play in the UK North Sea on the Lancaster licence,” Victoria McCulloch said in an RBC note.
“We anticipate nine to 12 months of production data from now is required in order to fully understand the scale of the reservoir and sustainability of production.”
Together with its Greater Warwick Area (GWA) project, Hurricane aims to add net reserves of 750 million barrels to its portfolio.
In a coup for Hurricane, Spirit Energy, backed by Centrica , last year agreed to invest almost $400 million in exchange for 50% of GWA, where drilling is also underway and results are expected from the first well within weeks.
