The geologic architecture in sedimentary reservoirs affects the behavior of density-driven flow and dispersion CO2-rich brine. spatial organization connectivity facies types play an important role. Low-permeability may suppress fingering reduce vertical spreading, but also increase transverse mixing. This is more pronounced when structures create preferential pathways through connected types. We perform high-resolution simulations three-dimensional (3D) heterogeneous formations whose cannot...
Shale gas storage is a dominant factor to economically evaluate the shale play. A series of Lower Silurian Longmaxi marine samples in southeast Chongqing, China, were collected investigate reservoir characteristics, and suit methane adsorption isotherms fitted using supercritical Ono–Kondo model better understand capacity shale. The saturated monolayer presents greatly positive relationship with total organic carbon (TOC) content. negative clay was observed due predominant influence matter...
In order to better understand the impact of fractal features pore-throat structures on effective physical properties tight gas sandstones, this paper carried out constant-rate mercury injection tests, gas–water permeability analyses, helium-based porosity and nitrogen pulse decay measurements, SEM casting thin-section analyses 20 sandstone samples Shihezi Formation from 16 wells Sulige Gas Field in Ordos Basin, China. The dimensions pores corresponding two pore radius ranges, namely...
Routine core analysis, thin section epifluorescence and scanning electron microscopy (SEM) analyses were performed to delineate the reservoir qualities, pore systems, network characteristics of Devonian Donghetang sandstone samples. Nuclear magnetic resonance (NMR) measurements used gain insight into size distributions these sandstones. Fractal analysis was on NMR T2 spectrum measured at echo spacings 0.6 1.2 ms. Then relationships between parameters fractal dimension investigated. The...
To directly measure the gas content in Benxi and Shanxi subformations of Ordos Basin NW China, a series canister desorption tests were carried out on 33 over-mature Lower Permian to Upper Carboniferous fresh shale cores (>3000 m) at both reservoir temperature (75–80 °C) an elevated 95 °C. Organic chemistry X-ray diffraction analyses replicate samples used establish relationships between rock composition. Geochemical measurements show that total organic carbon (TOC) contents range from 0.49...
Interactions between rock minerals and hydraulic fracturing fluids directly impact the geochemical geomechanical properties of shale formations. However, mechanisms reactions in unconventional reservoirs remain poorly understood. To investigate fluids, a series batch reactor experiments were undertaken. Three samples with different mineralogical compositions three fluid [deionized water, deionized water + 2% potassium chloride (KCl), 0.5% choline (C5H14ClNO)] used. Experiments undertaken at...
Abstract Rock elastic moduli are one of the major perspectives for hydraulic fracturing design. Among all them, Young's modulus and Poisson's ratio essentially control fracture aperture proppant placement. The objective this work is to predict by applying data mining techniques as a comparison experimental measurements. We have collected attributes representing pore structure, mineralogy geomechanical characteristics. implemented classification such k-means, hierarchical PAM (partition...
With gradually increasing enhancing population and industrialization, exploitation of shale gas is in the world to satisfy growing demand for energy worldwide. To exploit efficiently, accurate assessment place (GIP) necessary determining production strategies. Unlike free dissolved gas, adsorbed contributes GIP up 85% due well-developed surface area micropores. Measured excess adsorption methane (up over 95% subsurface gas) often corrected absolute obtain actual amount under supercritical...
