Abstract: In contrast to existing methods wherein derived horizons are interpreted in isolation, the disclosure provides a process that does not interpret patches themselves but determines the relationships between patches, in order to associate and link patches to derive a holistic geological interpretation. Predefined patches, such as from a pre-interpreted suite, are received as inputs to determine the relationships and derive an interpretation for a complete volume. In one aspect the disclosure provides an automated method of generating a geological age model for a subterranean area. In one example, the automated method includes: (1) abstracting seismic data of a subsurface into a limited number of patches, (2) abstracting the patches by defining patch-links between the patches, and (3) generating a geological age model of the subsurface by solving for the relative geological age of each of the patches using the patch-links.

Abstract: A method for imaging a formation of a subsurface includes receiving input data d related to the subsurface, generating synthetic data u related to the subsurface, by applying an implicit finite-difference approach to a reflectivity model r, updating a velocity model V based on the input data d and the synthetic data u, and generating an image of the formation in the subsurface based on the updated velocity model, wherein the formation is used to locate natural resources.

Abstract: A system and method are disclosed for determining an internal multiples-free seismic dataset. The method includes obtaining a seismic dataset, wherein the seismic dataset comprises a plurality of space-time gathers, determining a first truncation operator, wherein the first truncation operator mutes samples of each trace after a first predetermined intercept time in a transform domain, and determining a second truncation operator, wherein the second truncation operator mutes samples of each trace before a second predetermined intercept time in the transform domain. The method further includes applying Marchenko internal multiple attenuation on the seismic dataset using the first and second truncation operators to determine the internal multiples-free seismic dataset.

Abstract: A computer-implemented method for integrating a full wavefield inversion (FWI) solution with a non-FWI solution. Computational costs for generating a large bandwidth FWI solution, such as to 50 Hz, may be considerable. However, limiting the FWI solution to a narrower frequency band, such as up to 20 Hz, renders the FWI solution less useful. To remedy this, an FWI solution that is band limited, such as up to 20 Hz, is integrated with a non-FWI solution. The non-FWI solution may comprise seismic stacks or non-seismic data, and is directed to a different frequency band, with at least part of the non-FWI solution frequency band being greater than 20 Hz. In this way, bandwidth extension may be performed for at least one subsurface physical property parameter by combining a band limited FWI solution with a non-FWI solution.

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: Methods and systems for improving the efficiency of ALFT are disclosed. The methods include obtaining a seismic dataset of a subterranean region, generating a window function, transforming the seismic dataset from a first domain to a second domain using a transform function, and transforming the window function from the first domain to the second domain using the transform function. The methods also include generating an input spectrum from the transformed seismic dataset, iteratively, or recursively, until a condition is met, for each slice, estimating a weight function, generating a weighted input spectrum, identifying a strongest attribute, determining an output spectrum based on the identified strongest attribute, and updating the input spectrum by removing the identified strongest attribute. The methods further include determining an output spectrum volume by combining the output spectrum for each slice, and generating an output seismic dataset using an inverse transform function and the output spectrum volume.
