Abstract: A method is described for seismic imaging including receiving a digital seismic image representative of a subsurface volume of interest and an earth model; decomposing the seismic image into a set of image subsets based on an image-domain decomposition function; forward modeling each image subset to generate a set of synthetic data subsets; decomposing each data subset into a set of data sub-subsets based on a data-domain decomposition function; imaging data sub-subsets using the earth model to generate a set of image sub-subsets; and combining the set of image subsets based on a criterion to create a high resolution seismic image. The method may be executed by a computer system.

Abstract: A method is described for monitoring a stimulated reservoir volume (SRV) including receiving simulation parameters, performing 3D fully coupled quasi-static poro-elastic finite difference modeling using the simulation parameters, wherein the 3D fully coupled quasi-static poro-elastic finite difference modeling is based on a rescaling of solid rock and fluid flow density parameters and generates simulated temporal quasi-static stresses, and pore pressure. In addition, simulated stresses may be used for performing calculation of the 3D rotation of the simulated stresses to principal directions; performing calculation of the temporal 3D Mohr-Coulomb (MC) failure criteria from the calculated principal stresses and the simulated pore pressure for all or selected time steps; and displaying the computed temporal MC failure criteria results on a graphical display. The method may also be used in time-lapse monitoring of the reservoir for microseismic depletion delineation.

Abstract: A method is described for seismic imaging including receiving a seismic dataset representative of a subsurface volume of interest and an earth model; decomposing the seismic dataset into a set of data sub-sets based on a decomposition function; imaging each data sub-set using the earth model to generate a set of image sub-sets; and combining the set of image sub-sets based on a criterion to create a high resolution seismic image. The method may be executed by a computer system.
