Transocean rig starts Hurricane well campaign west of Shetland

Offshore staff

GODALMING, UK – The semisubmersible Transocean Spitsbergen has spudded a pilot well on Hurricane Energy’s Lancaster oil field west of Shetland.

Well 205/21a-7 well is on the P1368 Central license in which Hurricane has 100% interest.

This is the first of two wells designed to refine the resource range of the fractured basement oil field. The second, a horizontal side track, will likely provide a second producer for a future development.

The main aims of the pilot well are to:

1.) Confirm the depth of the oil-water contact, allowing Hurricane to determine the height of the oil column

2.) Confirm and evaluate a potential basement aquifer that could provide pressure support to the overlying oil column

3.) Assess potential for upside in the overlying Victory sandstone.

Following logging and testing, the well will be permanently P&A’d using cement. The rig will then spud the 205/21a-7z 1 km horizontal side track well.

In this case, the objectives include:

1.) Reconfirming production rates achieved in the 2014 horizontal well, demonstrating that other parts of the reservoir can also deliver commercial flow rates

2.) Further quantifying the reservoir characteristics through shut-in/pressure build-up tests to determine if there are any reservoir barriers, in the process clarifying how the reservoir fracture system performs.

Operations are estimated to take around four months to complete.

Dr. Robert Trice, CEO of Hurricane, said the program should give a clearer picture of Lancaster’s contingent resource range of 62-456 MMboe, facilitating a final investment decision and field development planning.
