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 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.

This book was released on 2018 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: The North Slope of Alaska includes a world-class conventional petroleum system that has been producing for approximately 40 years. While the regional stratigraphy includes multiple proven source and reservoir rocks, the Middle to Upper Triassic Shublik Formation (Fm.) is the most prolific. The decline in conventional hydrocarbon production on the North Slope and the presence of high quality source rocks inspire the evaluation of the Shublik Fm. as an unconventional petroleum system where oil or gas are produced directly from source rocks. The Shublik Fm. is a heterogeneous calcareous shale and limestone interval that has been interpreted to indicate deposition influenced by marine upwelling. Lithofacies observed in outcrop consist of intervals of non-resistant organic-rich packages that are interbedded with resistant coarsening upward rhythmic depositional successions of phosphatic and carbonate parasequences. The heterogenous characteristics of the microfacies is one of the challenges in the unconventional exploration of the Shublik Fm. Detailed microfacies descriptions, as part of this study, document the complex lithologies and identify patterns in the occurrence of the microfacies. Microfacies descriptions are the building blocks to identify stacking patterns that define the parasequences. The parasequences observed in core, outcrop, and petrographic analysis are calibrated to well logs to map relevant stratigraphic intervals on a regional scale. A targeted interval for the unconventional exploration of the Shublik Fm. is identified using a relative brittleness index. Flat clam and phosphatic parasequences are the primary packages present within the targeted interval. The parasequences are comprised of small-scale brittle and ductile couplets. High resolution pore imaging and mechanical stratigraphy characteristics are documented within the interval. Pore types and networks provide potential storage and migration pathways within unconventional resource systems. Pore types were imaged at a high resolution using scanning electron microscopy. Pore types that are present within the Shublik Fm. include interparticle, intraparticle, porous floccules, moldic, microfracture, and microchannel. The phosphatic limestone facies contains the greatest amount of porosity including interparticle, intraparticle, and moldic within the phosphate nodules and matrix and fractures surrounding phosphate nodules. Microfracture, microchannel, and intraparticle porosity are the primary pore types within the flat clam facies. Mechanical stratigraphy has a direct impact on the success of hydraulic fracturing. The microfacies descriptions identify laminae scale mechanical stratigraphy characteristics which include erosional surfaces, laminations, graded bedding, mineralogical variation, and textural anisotropy and isotropy. A regional correlation of the targeted interval was developed building upon previous work and utilizing sequence stratigraphic models. Significant parasequence surfaces are readily identified in the well log signatures. The challenge of the heterogeneity of the Shublik Fm. is simplified first by identifying a targeted interval consisting of brittle and ductile packages enriched in TOC. Then recognizing the parasequences contained as part of the interval which include significant characteristics pertaining to pore networks and mechanical stratigraphy. Combining methods and results of this study provides an important component to evaluating the Shublik Fm. as a potential unconventional resource system.

This book was released on 2016 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analysis of sedimentary lithologies and structures in selected outcrop sites at Slope Mountain, Alaska identified thirteen distinct facies within a subsample of the Cretaceous (Albian-Cenomanian) Nanushuk Formation. Based on the distribution of the thirteen facies, this study defines five unique facies associations at Slope Mountain, each representing a specific depositional environment. The facies associations are as follows: 1) distributary channel bar, 2) tidal channel, 3) upper shoreface, 4) distributary mouth bar, and 5) fluvial channel. The relative stratigraphic positions of the facies associations in outcrop have implications for fluctuations in shifting shoreline positions within the Nanushuk Formation over time. The progression of facies associations within several hundred meters of section analyzed in this study depict a shift from a regressive deltaic system (sedimentation>accommodation) to an alluvial system affected by local transgression (sedimentationaccommodation). Despite significant overall accommodation in the Colville basin, the dominant pattern of Nanushuk Formation sedimentation is highly regressive, with significant progradation and aggradation of deltaic and alluvial deposits throughout the Albian-Cenomanian.
