... selected to represent varying bulk density (ρ b ), total porosity (ϕ), and total organic carbon (TOC). Tests were conducted at confining stresses representative of the effective mean in-situ stress. We observed three distinct stress-strain behaviors that correlate with changing ϕ, ρ b , and TOC. Type-1...

... in larger pores (20-200 nm), with the precipitation being more dominant, leading to a decrease in total porosity by up to 10%. The alteration of the cement plugs lead to an increase in matrix tortuosity by 6 and 3 times after 2 and 5 weeks of exposure respectively. Although dissolution and precipitation...

... are intended for CO2 sequestration, and the Belloy formation is utilized for water disposal. Amplitude versus Offset (AVO) seismic inversion methods are used to determine the formations’ elastic properties. Rock physics analysis is conducted to estimate porosity and mineralogy variations allowing for a better...

... to better quantify fluid fractions. This workflow provides a multiple porosity-fluid saturation dataset to minimize the uncertainty in petrophysical measurements. For clay minerals, significant difference in relaxation time or total signal amplitude as a function of frequency is not observed. However...

.... Density, P-wave and S-wave impedance are estimated, from which Young’s Modulus and Brittleness Index are calculated. The second CNN simultaneously estimates the effective porosity, clay, kerogen, and quartz volumes. A Bayesian lithofacies method was used to perform facies classification and generate...

... Abstract Natural fractures are important for oil and gas production in tight reservoirs that are usually characterized by ultralow matrix porosity and permeability. Natural fractures can be characterized by core sample analysis, image logs, production data, and other data sets; however, some...
