Methods For Performing Fast Discrete Curvelet Transforms Of Data

View page
US Patent:
20070038691, Feb 15, 2007
Filed:
Apr 7, 2006
Appl. No.:
11/400048
Inventors:
Emmanuel Candes - Los Angeles CA, US
David Donoho - Setauket NY, US
Laurent Demanet - Pasadena CA, US
International Classification:
G06F 17/14
US Classification:
708400000
Abstract:
Fast digital implementations of the second generation curvelet transform for use in data processing are disclosed. One such digital transformation is based on unequally-spaced fast Fourier transforms (USFFT) while another is based on the wrapping of specially selected Fourier samples. Both digital transformations return a table of digital curvelet coefficients indexed by a scale parameter, an orientation parameter, and a spatial location parameter. Both implementations are fast in the sense that they run in about O(nlog n) flops for n by n Cartesian arrays or about O(N log N) flops for Cartesian arrays of size N=n; in addition, they are also invertible, with rapid inversion algorithms of about the same complexity.

US Patent:
20200386097, Dec 10, 2020
Filed:
Oct 7, 2019
Appl. No.:
16/594482
Inventors:
- Cambridge MA, US
Pawan Bharadwaj Pisupati - Melrose MA, US
Laurent Demanet - Cambridge MA, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
E21B 49/00
E21B 44/00
E21B 47/12
E21B 47/06
G01V 3/34
G01V 3/30
G01V 1/48
Abstract:
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.

Systems And Methods For Focused Blind Deconvolution

View page
US Patent:
20200213164, Jul 2, 2020
Filed:
Mar 12, 2020
Appl. No.:
16/817089
Inventors:
- Cambridge MA, US
Laurent Demanet - Cambridge MA, US
Aime Fournier - Boulder CO, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
H04L 25/03
E21B 47/14
Abstract:
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.

Systems And Methods For Detecting Seismo-Electromagnetic Conversion

View page
US Patent:
20190293832, Sep 26, 2019
Filed:
Mar 21, 2019
Appl. No.:
16/361073
Inventors:
- Cambridge MA, US
Aime Fournier - Boulder CO, US
Laurent Demanet - Cambridge MA, US
Assignee:
Massachusetts Institute of Technology - Cambridge MA
International Classification:
G01V 3/38
E21B 44/00
E21B 47/06
G01V 3/12
G01V 1/28
Abstract:
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.
