LONDON, Nov. 14 -- Antrim Energy Inc. is weighing development options for two fields on UK North Sea Block 21/28a after completing its acquisition from ENI of a 75% working interest and becoming operator (OGJ Online, Oct. 3, 2006).
Antrim spent $8 million to obtain the interest and will pay ENI $10 million more once the UK Department for Trade and Industry approves its field development plan.
Three Block 21/28a wells in Fyne and Dandy oil fields have tested 1,200-3,600 b/d of 21-25º gravity oil.
The fields are combination structural-stratigraphic traps of Middle Eocene Tay sandstones with secondary potential in underlying Jurassic strata. The sandstones occur at average depths of 4,400 ft subsea and have porosities of 24-32% and permeabilities as high as several darcies.
Kerry Fulton, Antrim chief operating officer, told OGJ the company is considering development of the fields via subsea wells tied back to a platform or floating production, storage, and offloading vessel. He said the company is "fine-tuning our seismic data" before submitting the development plan.
