Laboratory-Scale Petrophysical Evaluation Of Lithofacies Effect On Reservoir & Source Quality And Core-Calibrated Well Log Analysis In Pennsylvanian-Permian Wolfcamp-Spraberry Intervals, Midland Basin, Texas, Usa, Samuel John Becker
Earth & Environmental Sciences Theses - Archive
The “Wolfberry” play, which is made up of the Spraberry and Wolfcamp formations, is an important resource for the exploitation of hydrocarbons with a need for additional petrophysical understanding. Although the Wolfcamp is categorized as a shale, it is a complex and heterogeneous formation composed of multiple facies. The unique lithological composition of each facies controls formation properties, which further drive reservoir/source quality. With the integrated laboratory- and field-scale analyses, this study uses mostly laboratory petrophysical evaluation to gain insight on the relationship between facies and reservoir/source quality in the Lower Spraberry and Wolfcamp intervals throughout the Midland Basin. To …
Controlling Factors Of River Water Stable Isotope Compositions And Middle To Late Cenozoic Deposition And Surface Uplift History Of The Southern Rocky Mountains, U.S.A., Lu Zhu
Earth & Environmental Sciences Dissertations - Archive
The Cenozoic topographic evolution of the Rocky Mountains (Rockies) and Great Plains in the western U.S.A. reflect a combination of mantle geodynamic, crustal deformation and surface erosional processes. This region was near sea-level during the Late Cretaceous and is characterized by high topography and high relief at present. Different hypotheses involving crustal shortening and thickening, mantle dynamic process, and enhanced erosion induced by climate change have been proposed to interpret the Cenozoic surface uplift. The timing and magnitude of surface uplift hold the key to test these different hypotheses. This dissertation identifies the controlling factors of modern river water isotopic …

Earth & Environmental Sciences Theses - Archive
The Avalon Shale is a Permian-aged stratum and represents a significant rock unit within the Bone Spring, of the Delaware basin of West Texas and Southeastern New Mexico. The Delaware Basin has witnessed increased drilling activities owing to the resurgence in the Permian basin, where organic-rich shales of the Wolfcamp, Avalon and tight Bone Spring Sands, are the primary targets. However, this boom in production has been constrained by low recovery from tight reservoirs. This problem has continued to attract attention because of the need to improve the reservoir performance of the Bone Spring wells. To achieve this objective, a …
History-Matching And Forecasting Of Three Unconventional Oil And Gas Reservoirs Using Decline Analyses And Type Curves, Hammad Ahmed
History-Matching And Forecasting Of Three Unconventional Oil And Gas Reservoirs Using Decline Analyses And Type Curves, Hammad Ahmed
Earth & Environmental Sciences Theses - Archive
Reservoir modeling of shale gas and tight oil presents numerous challenges due to complicated transport mechanisms and the existence of fracture networks. Even then, oil and gas companies have not slowed down on shale hydrocarbon investment and production using horizontal well drilling and hydraulic fracturing techniques. Many small oil companies may not have the budget to build a reservoir model which typically requires drilling test wells and performing well logging measurements. Even for large oil companies, building a reservoir model is not worthwhile for the evaluation of small-scale oil fields. Comprehensive numerical simulation methods are likely impractical in those cases. …

Tracing Paleozoic Siliciclastic Sediment Dispersal To The Fort Worth And Midland Basins: Implications For Paleogeography And Organic Matter Accumulation, Ohood Bader Al Salem
Earth & Environmental Sciences Dissertations - Archive
The Fort Worth and Midland Basins in central and West Texas are major petroleum-producing systems in North America. The provenances of the thick Paleozoic sedimentary rocks in both basins are poorly constrained, although they are important to the understanding of these petroleum systems. The siliciclastic grains of the upper Paleozoic in the two basins were proposed to be derived from local sources, including the basin-bounding Ouachita-Marathon orogen and crystalline basement-cored Ancestral Rocky Mountains, or distal source of the Appalachian highland. The distal source requires a transcontinental river system routing along the Appalachian-Ouachita forelands. Here I applied several provenance-tracking methods, including …

Investigation Of Petrophysical Properties And Fluid Migration In Unconventional Oil/Gas Reservoirs, Yuxiang Zhang
Earth & Environmental Sciences Dissertations - Archive
Petrophysics deals with the physical and chemical properties of petroleum-bearing rocks and their interactions with associated fluids. The investigation of petrophysical properties of interest, such as porosity, specific pore surface area, pore size distribution, permeability, fluid saturation, and wettability, is of great importance to understand hydrocarbon storage and transport in unconventional oil/gas reservoirs, especially shale reservoirs. Characterized as low-porosity and ultra-low permeability, unconventional reservoir rocks have complicated pore structure which is significantly affected by their dominant compositions (minerals and organic matters) and vary along with the depositional environment, burial depth, diagenesis, and thermal maturity. Therefore, to better understand the shale …

Shale Gas/Oil Reservoir Characterization And Maturity Determination Based On Various Experimental Analyses, Md Golam Kibria
Earth & Environmental Sciences Dissertations - Archive
Despite the successful shale hydrocarbon exploration and production in the U.S. started about 20 years ago, the producing wells experience a current low total recovery of tight oil (5%-10%) and shale gas (12%-30%). One of the critical obstacles to sustainable shale development is related to the low recovery factor, which still needs much investigation. Hydrocarbon movement through shale reservoirs is controlled by two factors related to pore structure: one is pore size distribution (geometry), and another one is pore connectivity (topology). This Ph.D. research is divided into three different projects: 1) The 1st one is to improve the understanding of …
