    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 for determining propped fracture dimensions for a parent well includes hydraulic fracturing a stage of a child well to form a child well fracture, as well as, during the hydraulic fracturing process, measuring, via the parent well, data that are indicative of the formation of a hydraulic connection between the wells via interaction between the wetted front of the child well fracture and the propped region of a corresponding parent well fracture. The method includes measuring TFR (or VFR) data corresponding to the formation of the hydraulic connection between the two wells. The method includes estimating a child well fracture dimension when the hydraulic connection was formed using the TFR data, in combination with a fracture growth profile, and estimating a propped fracture dimension of the parent well fracture based on the estimated dimension of the child well fracture and the distance between the wells at that stage.

    Abstract: A proppant including polyolefin-coke composite granules, a hydrocarbon well including such a proppant, and methods of forming the hydrocarbon well using such a proppant are provided herein. The hydrocarbon well includes a wellbore that extends within a subsurface region and a downhole tubular that extends within the wellbore and defines a tubular conduit. The hydrocarbon well also includes a number of perforations formed within the downhole tubular and a number of fractures formed within the subsurface region proximate to the perforations. The hydrocarbon well furthers include the proppant positioned within at least a portion of the fractures. The proppant includes a number of polyolefin-coke composite granules, where a characteristic dimension of each polyolefin-coke composite granule is at least 50 micrometers (μm) and at most 3 millimeters (mm), and where each polyolefin-coke composite granule includes a number of polyolefin polymer chains and at least one petroleum coke granule.
