No moveable hydrocarbons in Alaskan Winx-1 well
Initial wireline data points to low quantities of non-mobile oil in both the Nanushuk and Torok formations in Winx-1. The well, drilled by a consortium of independent companies (88 Energy, Red Emperor Resources, Otto Energy and Pantheon Resources )
was targeting the Nanushuk play fairway of Alaska’s North Slope and was looking to build on Repsol’s 2017 success at Horseshoe-1. The Repsol well is located four miles to the west of Winx-1 and had extended the Nanushuk play 20 miles to the south of the Pikka Unit.
Preliminary interpretation indicates that oil saturation and fluid mobility in the Nanushuk was negatively impacted by the presence of dispersed clay in the matrix. While this is a known characteristic elsewhere in the Nanushuk, Winx-1 did not benefit from the presence of further high quality oil saturated sandstones as typically seen in successful wells in the play.
