Patent number: 11307324Abstract: Drilling systems and related methods are disclosed. A drilling systems may include a tool configured to be positioned at an end of a drill string adjacent a drill bit, and the tool may be configured to detect localized seismo-electromagnetic conversion from one or more predetermined positions within a medium ahead of the drill bit. The tool may include two or more pressure sources configured to generate focused acoustic and/or elastic energy at the one or more predetermined positions to generate the localized seismo-electric conversion.Type: GrantFiled: March 21, 2019Date of Patent: April 19, 2022Assignee: Massachusetts Institute of TechnologyInventors: Niels Grobbe, Aime Fournier, Laurent Demanet

Patent number: 11085293Abstract: Drilling systems and related methods are disclosed. A drilling system may include a drill bit positioned at an end of a drill string, and one or more sources and receivers positioned on the drill string behind the drill bit. The sources may be configured to emit signals into a medium surrounding a borehole in which the drill string extends, and the signals may cause a response in the medium at one or more predetermined positions ahead of the drill bit, and response signals may be measured by the one or more receivers. A processor may use the measured response signals to iteratively update an estimate of a property of the medium at the predetermined position, which in some embodiments, may be done using a sequential estimation process, as the drill string is advanced into the medium.Type: GrantFiled: October 7, 2019Date of Patent: August 10, 2021Assignee: Massachusetts Institute of TechnologyInventors: Aime Fournier, Pawan Bharadwaj Pisupati, Laurent Demanet

Patent number: 10979254Abstract: Systems and methods for performing focused blind deconvolution of signals received by a plurality of sensors are disclosed. In some embodiments, this may include determining a cross-correlation of first and second signals, obtaining a cross-correlation of a first response function and a second response function based on the cross-correlation of the first and second signals and subject to a first constraint that the first and second response functions are maximally white, and obtaining the first and second response functions based on the cross-correlation of the first and second response functions and subject to a second constraint that the first and second response functions are maximally front-loaded.Type: GrantFiled: March 12, 2020Date of Patent: April 13, 2021Assignee: Massachusetts Institute of TechnologyInventors: Pawan Bharadwaj Pisupati, Laurent Demanet, Aime Fournier

Publication number: 20140278110Abstract: A method, apparatus, and program product utilize global sensitivity analysis (GSA) based on variance decomposition to calculate and apportion the contributions to a total variance of a measurement signal from uncertain input parameters of a subsurface model in connection with designing targeted surveys. Through the use of global sensitivity analysis in this manner, the geometry for a survey may be determined based on a desired target of the design, e.g., based on spatial properties (e.g., reservoir zone of interest) and/or physical properties (e.g., porosity, fluid density, rock physics properties) to select locations (e.g., source-receiver pairs) with greater uncertainty contributions from parameter group(s) of interest.Type: ApplicationFiled: March 12, 2014Publication date: September 18, 2014Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: NIKITA CHUGUNOV, TERIZHANDUR S.

Publication number: 20130261981Abstract: Computing systems and methods are disclosed. In one embodiment, a technique is provided that includes receiving data representing at least in part a structure of interest; and processing the data in a processor-based machine to represent the data as a data structure including a plurality of contiguous data segments and at least one disjoint section, which separates two of the contiguous data segments. The technique includes processing the data structure based at least in part on the disjoint section(s) exhibiting ergodic behavior to determine at least one property of the structure.Type: ApplicationFiled: April 3, 2013Publication date: October 3, 2013Applicant: WESTERNGECO L.L.C.Inventors: AIMÉ FOURNIER, KONSTANTIN S.
