Publication number: 20230129626Abstract: Generally, seismic data may provide valuable information with regard to the description such as the location and/or change of hydrocarbon deposits within a subsurface region of the Earth. The present disclosure generally discusses techniques that may be used by a computing system to analyze a data set including weak-coherence signals (e.g., non-coherent blending noise). In particular, a computing system may detect portion of the weak-coherence signals of a gather due to the overlap of selected seismic source excitations and use a mask to isolate coherent signals and the other weak-coherence signals from the masked portion of weak-coherence signals. The coherent signals and other weak-coherence signals may be iteratively processed and used to predict values of the masked weak-coherence signals.Type: ApplicationFiled: September 29, 2022Publication date: April 27, 2023Applicant: BP Corporation North America Inc.Inventors: Kang FU, Joseph Anthony DELLINGER

Patent number: 11269094Abstract: A compact seismic source for seismic acquisition generating a humming signal includes a casing and a low-frequency reciprocating drive. The casing defines a fluid tight chamber and comprises a first casing section and a second casing section of roughly equal mass. The drive is disposed within the fluid tight chamber and, in operation, reinforces the natural reciprocating oscillation of the first and second casing sections relative to one another at a low seismic frequency. In one aspect, this action omni-directionally radiates the low frequency, humming seismic signal. On another aspect, the compact seismic source is substantially smaller than the wavelength of the low seismic frequency. Such a compact source may be deployed to omni-directionally radiate a low frequency, humming seismic signal during a seismic survey.Type: GrantFiled: May 1, 2018Date of Patent: March 8, 2022Assignee: BP Corporation North America Inc.Inventors: Joseph Anthony Dellinger, Mark Francis Lucien Harper, Graham Anthony Openshaw

Patent number: 11105946Abstract: A method of seismic exploration above a region of the subsurface containing structural or stratigraphic features conducive to the presence, migration, or accumulation of hydrocarbons comprises accessing at least a portion of a blended seismic source survey, separating the at least two interfering seismic source excitations using inversion separation, producing one or more source gathers based on the separating, and using the one or more source gathers to explore for hydrocarbons within said region of the subsurface. The blended source seismic survey contains at least two interfering seismic source excitations therein, and the seismic source excitations can be produced by seismic source types having different signatures or frequency characteristics.Type: GrantFiled: October 9, 2019Date of Patent: August 31, 2021Assignee: BP CORPORATION NORTH AMERICA INC.Inventors: Raymond Lee Abma, Joseph Anthony Dellinger, Kang Fu

Patent number: 10802167Abstract: The presently disclosed seismic acquisition technique employs a receiver array and a processing methodology that are designed to attenuate the naturally occurring seismic background noise recorded along with the seismic data during the acquisition. The approach leverages the knowledge that naturally occurring seismic background noise moves with a slower phase velocity than the seismic signals used for imaging and inversion and, in some embodiments, may arrive from particular preferred directions. The disclosed technique comprises two steps: 1) determining from the naturally occurring seismic background noise in the preliminary seismic data a range of phase velocities and amplitudes that contain primarily noise and the degree to which that noise needs to be attenuated, and 2) designing an acquisition and processing method to attenuate that noise relative to the desired signal.Type: GrantFiled: August 28, 2018Date of Patent: October 13, 2020Assignee: BP Corporation North America Inc.Inventors: Andrew James Brenders, Joseph Anthony Dellinger

Patent number: 10120086Abstract: There is taught herein a system and method for creating an improved seismic source signal by applying a feedback mechanism, active adaptive control, to perturb a resonator device configuration on the fly so as to ensure that the overall trajectory of the sweep is correctly produced, even though the precise details of each oscillation of the source are still not constrained. An embodiment teaches a method for adjusting the squeeze piston or tow depth of a resonant piston seismic source to bring the resonant frequency to a desired value. As a consequence, the resulting seismic signal is improved as compared with seismic signals acquired via resonators that do not utilize the instant teachings.Type: GrantFiled: October 15, 2014Date of Patent: November 6, 2018Assignee: BP Corporation North America Inc.Inventors: Mark Francis Lucien Harper, Joseph Anthony Dellinger
