... Permeability is the important property controlling fluid transport in fractured porous reservoirs. Since spatial variations and anisotropy in permeability are the intrinsic characteristics due to the heterogeneous and anisotropic structures fluid flow through in actual gas-bearing fractured...

... storage potential in Texas. Based on recent stratigraphic formation databases (Enverus, 2023) and public-sourced geothermal data, we identify and map key formations most likely to sustain low effective permeability in large portions of the Texas Gulf Coast and Permian Basin, including the Spraberry...

... attempt to accomplish this task by devising an algorithm to predict from sonic logs the secondary porosity formed by vugs and micro-fractures as well as their pore aspect ratios or pore space. The pore aspect ratios are categorized into intervals of permeable and low permeability in the aquifer...

... A hybrid workflow based on multiscale 3D imaging of cores, combined with limited experimental data sets (phi-K, Pc-MICP) has been developed to determine the distribution of porosity and permeability as input for a 3D numerical model at mm scale grid resolution. Porosity and permeability data...

... existing well control. Resistivity of reservoir rocks is mainly driven by the amount of brine in the rock, which is itself driven by permeability and pressure. Adding to these, well log measurements tend to underestimate the true reservoir resistivity, particularly in cases where the individual reservoir...

... We automatically extract lithofacies from a modern Mississippi point bar, in False River Louisiana U.S.A. We use K-means clustering with 5 types of data and identify 6 reasonable lithofacies. We integrate different geophysical data such as Electrical Conductivity (EC), permeability calculated...

... The permeability of a clastic porous medium is influenced by the grain size, shape, macro-micro pore network, and lithological distribution of clays. Tortuosity, which measures the complexity of the pore network and the degree to which flowline deviates from a straight line, has a direct impact...
