... patterns among seismic traces of stack volumes and well rock properties. Once a set of nonlinear functions is optimized in the well locations, to correlate seismic traces and rock properties, spatial response is estimated using the seismic volume. This seismic characterization process is directly dependent...

... and interpreted for estimating relative permeabilities. Formation testers are typically run when wells are drilled; therefore, using acquired data for estimating effective permeability can be cost-effective and less time-intensive compared to existing effective permeability estimation methodologies. However...

... (NCFE) where detailed geology and known oil-water relative permeability and capillary pressure curves are used. Various NCFEs' production and pressure data can be generated for different conditions and used to estimate the kr and Pc. Here, we used a commercial application to back calculate a set...

... to geological miss-positioning of the seismic image. Walkaway VSP data was used to estimate TI parameters for the Nahr Umr shale, which is a highly anisotropic formation and is a regional cap rock. Walkaway VSP was recorded using 16 level 3 Component (3C) downhole receiver array positioned across Nahr Umr...

Thus, the results of the developed methodology allow to improve well placement, stimulation operation design and field development strategies. hydraulic fracturing Reservoir Characterization microseismic...

... Abstract Accurate water saturation estimation in thin carbonate reservoirs is one of the major formation evaluation challenges in horizontal wells. This is mainly due to the strong shoulder bed effect of thick dense sections on the resistivity logs recorded in thin porous reservoir layers...

... Abstract Minimization of disparities between welltest and log-derived average permeabilities has always been an issue, particularly in carbonates where complex pore structures add on challenges to permeability estimation from wireline log data. The disagreement between permeability averages...
