XRD measurements of rock powders before and after reaction show decreases of pyrite, feldspar, and carbonate contents whiles...

... both the benches, but there are minor differences that could infer heterogeneity along lateral. The fluids however are from a different source compared to shallower 2 nd and 3 rd Bone spring sands and carbonates. Produced oils analyzed through GC-fingerprinting techniques agreed with mud gas isotopes...

... Abstract Organic-rich carbonates from the Upper Cretaceous period in southeastern Turkey are recognized as major unconventional hydrocarbon source rocks. A workflow for derisking the productivity of an unconventional play involves examining the S1 X 100/TOC ratios, which represent potentially...

... characterization, experimentation, and thermodynamic modeling approaches. Prior studies of mineral reactions in unconventional reservoir materials exposed to acidic (pH<2) or weakly acidic (pH<7) fracturing fluid showed that pH-driven carbonate and clay mineral dissolution, and oxidative dissolution...

... dictated by carbonate content (Ciezobka et al. 2018). The rock mineralogy was characterized using x-ray fluorescence, scanning electron microscopy, and electron probe micro-analyses. We monitored fluid transport through the rock using state of the art x-ray computed tomography techniques. Xenon gas, which...

... the hydrocarbon production. Integration of wireline logs and seismic data can help in estimating dominant production factors such as: fluid properties (porosity, saturation, total organic carbon, etc.), pore pressure spatial variability, and geomechanical properties (Poisson's ratio and Young's modulus). Our...

... using bandlimited log data was able to separate organic rich high TOC facies from siltstones and carbonates. To conclude, an integrated approach involving geology, petrophysics, rock physics and inversion feasibility study increased our understanding of the basin and set path for further analysis...

... (with clay 3.4 - 75.6 wt% and carbonate 1.9 - 83.7 wt%) were used to systematically investigate the effect of acid treatment on their fracture surface topography, mechanical properties and fracture conductivities. The mechanical properties of the fracture surface were measured using indentation tests...

... Abstract We describe the porosity and permeability of mudrocks and carbonates of the upper Wolfcamp in the Delaware Basin, and infer the impact of these properties on well production. We extracted representative core plugs from each lithology to determine total porosity and permeability. We...

... effects of mineral cements on the rock frame. A similar geochemical method for readily indicating the occurrence of authigenic carbonate has not been identified. This study documents trace element geochemical differences between biogenic (detrital) carbonate phases and associated cements so that chemical...

... the exposure to frac-fluids. This technique provides the measurement of Young’s modulus and hardness. In this study, 12 samples from the Permian basin with a wide range in Total Organic Carbon (TOC: 0–7 wt.%) and carbonate (5–87 wt.%) were selected. Each sample was divided into two companion specimens: one...

... carbonates. The present day structural configuration is inherited from two related regional compressional events; a) a NW-SE compression responsible for the anticline/syncline, lasting from Late Cenomanian to Early Eocene was created by India's continental drift, b) the late Cretaceous (starting in Turonian...

... carbonate-dominated units are generally much thicker (up to 3,000 ft; 915 m) immediately adjacent to shelf margin sources and they typically thin into the basin. Carbonate materials were shed off the adjacent shelves by gravity and current-driven forces and formed thick, carbonate-dominated slope deposits...

... to understand the variation in elastic properties in terms of geological changes that include: mineralogy, organic content and the likely onset of over-pressure. The geology was represented by a set of 5 elastic facies: carbonates, calcareous mudstones, siliciclastics, organic-rich and clay-rich shales...

... of organic-rich shale at micron resolution with the use of an automated stage. The acquired spectra were processed with standard spectral analysis software (LabSpec6) that resolved the ordered and disordered carbon bands used to estimate maturity. The non-organic phases were identified with peak-match...

... Abstract The Meramec and Osage formations in the Anadarko basin are known to be tight rocks with low-matrix porosity and potentially minor or major fracture permeability. The Meramec is predominantly composed of clastic rocks and carbonates, while the Osage has a shallow limestone facies...
