Oil Search finds oil in Pikka East Block, Alaska

Oil Search Ltd plans a side-track well following an oil and gas discovery in Pikka East block on the North Slope of Alaska.

The Mitqua-1 well, drilled to a 2,472 metres TD, encountered both oil and gas in the primary Nanushuk reservoir as well as in the deeper Alpine C target.

Oil Search said that preliminary evaluation of wireline logs, along with pressure and fluid sample data, indicates the Nanushuk Cretaceous-age Brookian sand has 60 metre of net pay comprising five metres of net gas and 55 metres of net oil pay.

Data collected from the secondary Alpine C sandstone reservoir indicates the presence of 16 metres of net hydrocarbon pay comprising six metres of net gas and ten metres of net oil pay.

Oil Search will plug the wellbore and drill a side-track. The Nanushuk section of the side-track will be cored and flow-tested to assess deliverability and provide a more accurate estimate of net pay thickness and commercial potential.

The Alpine C reservoir is to be evaluated by future appraisal wells.

Mitquq-1 is about eight km east north-east of the planned Nanushuk processing facility which will be built during Phase 2 of the Pikka Unit development.

Oil Search is operator of Pikka East with 51% interest. Repsol holds 49%.
