This book was released on 2005 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Cretaceous sandstones of the upper Torok and lower Nanushuk formations were deposited in a storm-dominated, deltaic depositional system during filling of the Colville basin, North Slope, Alaska. This study focuses on distal shelf and slope sandstones of the Torok Formation and shoreface sandstones of the Nanushuk Formation from Arc Mountain, Slope Mountain, Gunsight Mountain, and the Grandstand Test Well. Ten lithofacies were identified at these locations. Facies associations define depositional environments ranging from deep marine debris flows and tubidites deposited in distal shelf and slope settings of the Torok Formation to deposition of hummocky cross-stratified sandstones deposited above storm wave base in the proximal shelf settings of the Torok/Nanushuk transition. Sandstones from these locations are fine grained and include abundant detrital grains of quartz, chert, various lithic fragments, and feldspar. Compositionally these sandstones plot as litharenites to sublitharenites and are derived from a quartzose to transitional recycled orogenic provenance. These sandstones record the uplift of the ancestral Brooks Range and exhumation of the Endicott Mountain allochthon. There is a decrease in lithic material from the deeper water outer shelf setting to the storm dominated shoreface setting that is attributed to increased reworking and winnowing by waves in the higher-energy, shallow water settings"--Leaf iii.

Book excerpt: 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).

This book was released on 2013 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: I interpret sedimentary facies and depositional environments from the Albian-Cenomanian Nanushuk Formation of Alaska's North Slope from sedimentary structures observed in core samples and in outcrop in the National Petroleum Reserve - Alaska (NPRA) and surrounding areas, and support these interpretations with supplemental analyses of geophysical well logs and 40Ar/39Ar dating of volcanogenic deposits. The results have implications for the reservoir characterization of a shallow, frozen oil field at Umiat, Alaska, and for interpretations of the Colville foreland basin. In the central Brooks Range foothills the Nanushuk Formation comprises shallow marine and non-marine fades associations that can be grouped into marine-distributive and river-distributive systems. In wells at Umiat, Alaska, shoreface and wave-influenced deltaic sandstones (marine-distributive systems) occur at the base of the Nanushuk Formation, followed by a marine transgression and subsequent progradation of a delta complex (river-distributive system). The shift from marine-distributive to river-distributive systems is related to shelf building processes during the Albian-Cenomanian. Marine-distributive systems occurred at or near the shelf edge in a high-energy coastal environment, whereas river-distributive systems rapidly prograded over the shallow Nanushuk shelf following transgression. Marine-distributive conditions resumed when rapidly progradational river-distributive systems reached the shelf edge. This pattern occurs in the Umiat, Wolf Creek, and Grandstand No. 1 subsurface wells. The reservoir quality of the Nanushuk Formation varies strongly with facies. Well-sorted sandstones at the top of upward-coarsening successions in both marine- and river-distributive units have the highest permeabilities within the Nanushuk Formation. Marine-distributive units have low permeability anisotropy in contrast to river-distributive units due to better sorting in wave-influenced environments and the higher frequency of impermeable lamination surfaces in deltaic sandstones. Despite coarser grain size and similar depositional environments as lower Nanushuk Formation sandstones, transgressive units at the top of the Nanushuk Formation have low permeability, probably due to the presence of calcite cement. These results suggest hat the highest quality Nanushuk Formation reservoirs most likely occur in time transgressive, regionally extensive marine-distributive sandstones of the lower Nanushuk Formation.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past two decades there has been increased interest in the availability of hydrocarbon charge through a better understanding of petroleum geochemistry and the identification and characterization of petroleum source rocks. These rocks are geochemically unique and form under specific sets of circumstances. This book brings together both geologic and geochemical data from fifteen petroleum source rocks, ranging in age from Devonian to Eocene, that would otherwise be widely dispersed in the literature or available only in proprietary corporate databases. Much of this information, presented in either a tabular or graphic fashion, provides the petroleum explorationist and the geochemist with a framework to establish relationships among various geochemical indices and depositional settings.
