This workshop will examine cores from five wells (Wainwright 1, Square Lake Test Well 1, Wolf Creek Test Well 3, Umiat 18, and Fish Creek Test Well 1) representing a range of depositional settings in the Nanushuk Formation, from marine-influenced lower delta plain to outer shelf. A range of lower delta plain facies associations, including bayfill, distributary channel-fills, and crevasse deltas are featured in cores from Wainwright 1, Square Lake Test Well 1, and Wolf Creek Test Well 3. Storm wave-modified shoreface and delta-front facies associations comprise significant parts of the successions cored in the Square Lake and Wolf Creek wells and demonstrate that significant stretches of the Nanushuk coastline were subjected to powerful storm waves. The cored succession in Umiat 18 is comprised of prodelta and river-dominated delta-front facies associations. Heavily oil-stained outer shelf facies associations comprise the cored interval in Fish Creek Test Well 1. This workshop highlights facies associations likely to have the best reservoir potential and examines the relative importance of depositional setting, sandstone composition, grain size, and mechanical compaction on reservoir quality (porosity and permeability).
