Chemostratigraphy of Carbonate Gravity Flows of the Wolfcamp Formation in Crockett County, Midland Basin, Texas
… <p>This study utilizes five cores containing the Wolfcamp Formation from the southeastern slope of the Central Basin Platform in northwest Crockett County, Texas. High resolution chemostratigraphy was conducted using X-ray fluorescence along with total organic carbon, X-ray diffraction, and …

Diagenetic controls on porosity, thermal history, and hydrocarbons in the Wolfcamp A, eastern Midland Basin, Texas
A detailed study of a Wolfcamp A core from the eastern Midland Basin, west Texas, is used to understand the diagenetic history of the region and the controls on carbonate macroporosity. Transmitted-light microscopy, UV-epifluorescence, cathodoluminescence, and SEM-EDS microscopy, as well as δ18O, …

DEPOSITIONAL SYSTEMS INTERPRETATION OF EARLY PERMIAN MIXED SILICICLASTICS AND CARBONATES, MIDLAND BASIN, TEXAS
… determine the depositional setting of an Upper Wolfcampian and Lower Leonardian-aged mudstone succession. The studied sediments were deposited close to the center of the Midland Basin in a deep water, mixed carbonate and siliciclastic system. Core X was described on a centimeter scale and …

Characterization of Lower Permian Carbonate Subaqueous Gravity Flows in Crockett County, Texas
… This study utilizes core samples from the Wolfcamp Formation adjacent to the Central Basin Platform in five wells in Northwest Crockett County, Texas. The objective is to define lithofacies, explore facies relationships, and calibrate well logs to core in order to determine how changes in …

Low Interfacial Tension Foam Miscible Ethane Oil Recovery in Low Permeability Harsh Environments
… tests were performed for dead crude oil from the Wolfcamp Spraberry trend area using ethane and carbon dioxide, showing a lower MMP for ethane. A surfactant formulation capable of persistent foams in the presence of oil and Type I microemulsion in reservoir brine was identified to be thermally …

Mechanistic and probabilistic rate-time analysis of unconventional reservoirs
… models to wells from the Bakken/Three Forks, Wolfcamp/Spraberry and Haynesville Formations. The second part of this thesis displays the application of a probability approach to forecast the production of unconventional wells. The procedure involves sampling the production data, then matching …

Geological and Geochemical Investigation of the Petroleum Systems of the Permian Basin of West Texas and Southeast New Mexico
… the Woodford Shale, the Barnett Shale, the Wolfcamp Shale, and the Bone Spring Marls. The Spraberry source rock is mostly immature with respect to petroleum generation. Geochemical evidence strongly suggests source-rock deposition under suboxic and anoxic-suboxic conditions for all but the …

Natural and Experimentally-Simulated Stylolitic Porosity in Carbonate Rocks
… detailed petrographic analysis of Lower Permian Wolfcamp limestones. Based on the observed, natural vertical succession of the microfacies and on the petrographic study of thin sections, an ideal, shallowing-upward sequence was derived, and from it a horizontal model was constructed. The latter …

Investigating the performance of high viscosity friction reducers used for proppant transport during hydraulic fracturing
… successful implication of utilizing HVFRs in the Wolfcamp formation, in the Permian Basin was discussed. This study also provides a full comparative study of viscosity and elastic modulus between HVFRs and among fracturing fluids such as xanthan, polyacrylamide-based emulsion polymer, and …

3-D seismic characterization of the Niobrara Formation, Silo field, Laramie County, Wyoming
… present at all of the mapped horizons (basement, Wolfcamp, Permian salt, Sundance, Dakota, Niobrara, Pierre event, and the shallow horizon). In this study, the basement structure appeared to have some control on all of the main features. The open fracture directions within the main field area were …

Compositional modeling of gas injection in tight oil reservoirs
… The second case study based on the Permian Basin Wolfcamp Shale investigates the effect of multicomponent diffusion within the fractured tight oil reservoir. The simulation reveals that multicomponent diffusion has a minor impact on the performance of depletion as oil is the dominant phase. For …
