Office Action

§102 §103
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1 and 5-7 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Willis et al. in Non-Patent Literature “Mitigation of Zigzag Noise on DAS VSP Records Acquired in Vertical Wells” (see 23 MAY 2023 IDS). Regarding claim 1, Willis et al. teaches: A method (Abstract) comprising: receiving wellbore data comprising one or more seismic measurements (see “deploy wireline or coiled tubed based fiber-optic cables for acquiring distributed acoustic sensing (DAS) vertical seismic profile (VSP) data”, Introduction, Fig. 1); generating a seismic input image based on the one or more seismic measurements (see “Figure 2 represents an example of zigzag noise on a DAS VSP data set”, Introduction, Fig. 1; Fig. 2 b-d); processing the seismic input image to remove a zigzag noise in the seismic input image, wherein the zigzag noise represents noise in the one or more corresponding seismic measurements (see “A new algorithm…to help mitigate zigzag noise…2”extract the periodicity…3) remove the noise based upon the periodicity”, pg. 2; Fig. 2 e-h; see “denoise the data using the estimated period of the zigzag noise…perform adaptive subtraction…”, pg. 3); and outputting a denoised seismic image (Fig. 2 e-h; Fig. 3d denoised traces using deconvolution; Fig. 4e denoised traces using estimated wavelet; Fig. 5b). Regarding claim 5, Willis et al. teaches wherein the zigzag noise comprises a coupling noise caused by an uncoupling between an optic cable and a casing in a wellbore (see “a reverberating noise train…zigzag noise, appears in the distributed acoustic sensing vertical seismic profile records in zones with poor coupling”, Summary; see “deploy wireline or coiled tubing…do not have permanently installed fiber…this flexibility comes with the added liability of the potential for the fiber no to be acoustically well coupled to the wellbore wall…contaminated with zigzag noise..”, Introduction). Regarding claim 6, Willis et al. teaches wherein the zigzag noise comprises a noise region having varying polarities through the noise region in depth (Figs. 1-4). Regarding claim 7, Willis et al. teaches wherein the wellbore data comprises vertical seismic profile data that is collected using one or more fiber optic cables (see “Fiber-optic cables deployed by means of wireline or coiled tubing…”, Summary; see “deploy wireline or coiled tubed based fiber-optic cables for acquiring distributed acoustic sensing (DAS) vertical seismic profile (VSP) data”, Introduction, Fig. 1 “). Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 2-3 is/are rejected under 35 U.S.C. 103 as being unpatentable over Willis et al. in Non-Patent Literature “Mitigation of Zigzag Noise on DAS VSP Records Acquired in Vertical Wells” (see 23 MAY 2023 IDS) as applied to claim 1 above, and further in view of Dupont et al. in Foreign Patent Document. Regarding claim 2, Willis et al. teaches the limitations as indicated above. Willis et al. differs from the claimed invention in that it is silent regarding providing the seismic input image to a machine-learning model, wherein the machine- learning model comprises a deep-learning network.

The seismic data is processed in a data processing system ([0065], Fig. 7) comprising providing the seismic input image to a machine-learning model, wherein the machine- learning model comprises a deep-learning network (see “ processes…e.g., 2D or 3D seismic image data 456…Model 458 may be, for example, a deep learning model, e.g., a generative model such as a general adversarial network (GAN) model”, [0065] emphasis added). Dupont et al. establishes that it is known in the art to process seismic image data using machine learning, deep learning networks, general adversarial networks, etc. It would have been obvious to one of ordinary skill in the art before the effective filing date of the claimed invention to have combined the known seismic image processing techniques taught in Dupont et al in Willis et al. to improve Willis et al. with a reasonable expectation that it would result in improving the efficiency of Willis et al. thereby resulting increase accuracy of the denoised output results. Regarding claim 3, Willis et al. teaches the limitations as indicated above. Willis et al. differs from the claimed invention in that it is silent regarding providing the seismic input image to a machine-learning model, wherein the machine- learning model comprises a generative adversarial network. Dupont et al. teaches “analyze… seismic data…to generate image data for use in training machine learning algorithms” ([0021] machine learning model) wherein the seismic data may be collected via a wireline operation that suspends a wireline tool into a wellbore ([0040]-[0042]).
