Hurricane energy shares plunged on friday after the uk oil explorer greatly reduced its flagship jobs recoverable reserves.

The aim-listed company, which had hoped to open a brand new frontier into the north sea, said it expected to draw out 16m drums of oil from the lancaster field, far below its previous estimate of 37.3m drums over a six-year duration.

The group had directed to-be the first to ever show commercial production of oil ended up being feasible from fractured basement rock in uk oceans. the structures tend to be naturally occurring fissures into the granite that lies beneath the gentler sandstone where almost every other north sea coal and oil is available.

Hurricane said a technical analysis had generated a downgrade in recoverable resources since the contact point between oil and liquid, fundamental to how much crude there was, had been shallower than anticipated.

It added that recovering lancasters oil could be more complex than previously thought because of oil-bearing sandstone overlapping the basin flanks.

2020 is showing to-be a hugely difficult 12 months for hurricane, stated steven mctiernan, the companys president. we've had to deal with not only a significant fall-in oil costs and also the results of the covid-19 pandemic and poorer than anticipated reservoir overall performance from the lancaster early production system.

The organization reported a loss after tax of $307.7m in the first 50 % of the entire year, including a $238.9m impairment cost from the lancaster industry.

Shares in hurricane tumbled 48 % to 3.2p in early morning trading in london, expanding their drop since last november to significantly more than 90 %.

Hurricane said it would start thinking about injecting liquid into lancaster, which very first produced oil in may 2019, to improve the reservoir pressure so as to boost production.

The reserves and resources downgrade is going to be on top end of marketplace worries with really material modifications to your interpretations formerly offered into marketplace, stated colin smith, oil analyst at panmure gordon.

The high downward modification follows the deviation in summer of leader robert trice after the company admitted it may maybe not sustain production amounts during the lancaster area.
