The work’s objective is to characterize fractal naturally fractured reservoirs for obtaining the fractal parameters and reservoir properties from a pressure drawdown coupling a black-oil reservoir simulator with a power-law based (fractal) distribution of permeability...

... characteristics, ranging from an open conduit to a fully sealing fault, were studied to observe the behavior and migration of fluids over the course of the simulation to get a sense of what average fault permeability is necessary to get a material amount of fluid migration. More realistic variations of fault...

... Abstract This study investigates the dynamic adsorption behavior of an ATBS-rich hydrolyzed polyacrylamide (HPAM) polymer onto two different permeability carbonate rocks under varying salinity and high temperature conditions. The approach followed here is aimed at unraveling the complexities...

.... A total of 76 core plugs without fractures were studied from the Middle East region. The data set available included helium porosity, gas permeability and high-pressure mercury injection. MPSs were qualitatively classified according to the morphological characteristics of the MICP data correlated oil...

... of unavailable reservoir properties. While classical correlations in core analysis traditionally used porosity to predict permeability, the intricate interplay of lithology and pore geometry renders this approach unreliable for exclusive permeability estimation from porosity. This study aims to advance...

... from either single or few wells in the block. Variousmethods have been formulated in past to increase the robustness of SWRMs for relatively accurate forecasts. This research introduces a novel technique for the concurrent inversion of pivotal reservoirparameters – horizontal permeability, vertical...

By setting a constant confining pressure of 2200 psi and a Back Pressure Regulator (BPR) of 700 psi, the absolute permeability of brine was determined by flooding the core with different flow rates...

... Abstract Estimating missing petrophysical data, particularly in permeability/porosity core-analysis measurements is a challenge. The data gaps substantially increase uncertainty in multivariate statistical analysis degrading the accuracy of geomodeling. Data imputation algorithms can be used...
