Lancaster set for take-off as test well shows West of Shetland oil field is even bigger than expected

hurricane-energy-oil-rigHurricane Energy has confirmed that is Lancaster oil field west of Shetland is even bigger than first thought.

The company has completed the testing and logging phase of the 205/21a-7 pilot well. Operations are now progressing as planned to permanently abandon the pilot well reservoir section prior to side-tracking the top-hole to form the 7Z horizontal well.

But preliminary third party analysis from the pilot well indicates that a ‘very significant’ hydrocarbon column of at least 620 metres is present within the basement extending well below structural closure (which is 1,380 metres TVDSS) – confirming Hurricane’s reservoir model for the Lancaster field.

Provisional analysis indicates a minimum oil down to 1,620 metres true vertical depth subsea, and  240 metres TVD below structural closure. In addition, wireline fluid samples have demonstrated mobile oil of a gravity consistent with Lancaster oil to a depth of 1,646 metres

Testing of the basement reservoir yielded a maximum, natural flow rate of 6,600 bopd and a maximum flow rate of 11,000 bopd (artificial lift with an electrical submersible pump) of good quality 38 API oil with no formation water produced.

Dr Robert Trice, Chief Executive, Hurricane Energy, said: “Our initial assessment of the well results, which are subject to refinement of the provisional data, suggest that the Lancaster field is likely to be significantly greater than the 200mm bbls 2C case.

“The combination of high flow rates, an extensive oil column and underlying aquifer materially de-risks Hurricane’s plans for a future Lancaster field development and further underlines the potential of the fractured basement West of Shetland.”

The next stage of operations involves drilling of the Horizontal Well. This is designed to provide a second future production well and additional information to help optimally plan the Lancaster field development.
