Book Description
Eagle Ford Shale and the overlying Austin Chalk are the main producing plays throughout Central Texas. Due to the high clastic nature of Eagle Ford Shale and its ability to produce and maintain fractures from hydraulic fracturing, this formation quickly became the favored target over Austin Chalk for unconventional hydrocarbon production. The purpose of this study is to gain an understanding of nano-petrophysical properties of Eagle Ford Shale,which is still lacking.Drilling cores from three wells within the oil window of Eagle Ford Shale were examined at the Bureau of Economic Geology in Austin, TX. Multiple plug samples were taken of three wells and analyzed using various tests of XRD, pyrolysis, TOC, mercury intrusion porosimetry (MIP), pycnometry, (DI water and n-decane) vacuum saturation, low-pressure nitrogen gas physisorption, and fluid (DI water and n-decane) imbibition. These experiments will shed light on the nano-petrophysical properties of the reservoir regarding porosity, pore throat distribution, permeability, and flow patterns. MIP results from this study show that Eagle Ford Shale has a wide range of pore structure parameters with porosity values varying from 0.11 to 7.25% and permeability from 0.005 to 11.6 mD; all samples are dominated by two pore types: micro fractures (1-50 μm) and inter-granular(0.01-1 uμ) pores. TOC % showed an increase when quartz % increased as minerology has a direct influence on TOC %. Bulk density averages 2.54% while the grain density is slightly increased with an average of 2.64%. Kerogen values plot between group II and III indicating a hydrocarbon potential. Based on the nano-petrophysical analysis of Eagle Ford Shale, the results of this thesis are beneficial to further the understanding of the pore structure and fluid migration within the shale, and to better facilitate increased production.

Book Description
Cutting-edge techniques have always been utilized in petroleum exploration and production to reduce costs and improve efficiencies. The demand for petroleum in the form of oil and gas is expected to increase for electricity production, transport and chemical production, largely driven by an increase in energy consumption in the developing world. Innovations in analytical methods will continue to play a key role in the industry moving forwards as society shifts towards lower carbon energy systems and more advantaged oil and gas resources are targeted. This volume brings together new analytical approaches and describes how they can be applied to the study of petroleum systems. The papers within this volume cover a wide range of topics and case studies, in the fields of fluid and isotope geochemistry, organic geochemistry, imaging and sediment provenance. The work illustrates how the current, state-of-the-art technology can be effectively utilised to address ongoing challenges in petroleum geoscience.

Book Description
Shale resource systems include conventional source rocks, unconventional resources such as shale gas and shale oil system. Regardless of the type of shale resource system, the issues of petroleum formation processes (including petroleum generation, migration and storage) are very important in petroleum evaluation and exploration. Because of the complicated and different geological settings in the world, the evaluation approaches and workflows may not be easily implemented following those from successful examples. Thus, the mechanisms of petroleum formation are fundamental for petroleum exploration and production all over in the world. The reason this special issue focuses on the shale system is because the shale system is not only the main source rock type but also the main unconventional reservoir type in the world.

Book Description
Faults commonly trap fluids such as hydrocarbons and water and therefore are of economic significance. During hydrocarbon field development, smaller faults can provide baffles and/or conduits to flow. There are relatively simple, well established workflows to carry out a fault seal analysis for siliciclastic rocks based primarily on clay content. There are, however, outstanding challenges related to other rock types, to calibrating fault seal models (with static and dynamic data) and to handling uncertainty. The variety of studies presented here demonstrate the types of data required and workflows followed in today’s environment in order to understand the uncertainties, risks and upsides associated with fault-related fluid flow. These studies span all parts of the hydrocarbon value chain from exploration to production but are also of relevance for other industries such as radioactive waste and CO2 containment.
