Patent number: 10209386Abstract: Method for inverting, in the frequency domain (42), controlled source electromagnetic survey data (41) acquired using a time-division compound waveform made up of sub-sequences of different base waveforms, for example square waves of different frequencies. A windowed Fourier decomposition method is used, with the window size and shape designed in consideration of the sub-sequences. The window length may be twice the length of the compound waveform, or more. Alternatively the window length may be comparable to the sub-sequence length, or slightly less. Window shapes include cos2, rectangular, and triangular. The method addresses the problem of unknown arrival times for each sub-sequence, and also transition transients that occur between sub-sequences.Type: GrantFiled: June 27, 2013Date of Patent: February 19, 2019Assignee: ExxonMobil Upstream Research CompanyInventors: Scott C.

Patent number: 8547783Abstract: A method and apparatus for evaluating submarine formations, such as geological formations located generally under a body of water. Multiple hydrofoils (130), responding to moving water, hydrodynamic, or Bernoulli forces, provide controllable orientation and separation for multiple receivers (135) as they are towed (125) through water (110) in the course of a geophysical survey such as a controlled source electromagnetic survey. The inventive method can be used to provide mutual orthogonality for three antennas in a multiple component electromagnetic receiver.Type: GrantFiled: October 30, 2008Date of Patent: October 1, 2013Assignee: ExxonMobil Upstream Research CompanyInventor: Scott C.

Patent number: 8386182Abstract: A waveform design method is presented for controlled source electromagnetic surveying. A desired source spectrum (82) is specified based on a desired resistivity depth image resolution (81) with spectral amplitudes determined by expected noise levels (83). Techniques are disclosed for designing a source waveform to match the desired source spectrum. When better resolution is desired at a target zone, this leads to a required clustering of frequency components. A modulated waveform can be used to provide this clustering of frequency components.Type: GrantFiled: March 25, 2009Date of Patent: February 26, 2013Assignee: ExxonMobil Upstream Research CompanyInventor: Scott C.

Patent number: 8169222Abstract: A method for designing a controlled-source electromagnetic survey that will discriminate between a defined deep marginal-interest reservoir (2) and specified false positive resistivity structures of concern (3, 4, 5). A reservoir model and a false positive model are constructed for each false positive scenario. The resistivity of the false positive model may be tuned to give electromagnetic data similar enough to the reservoir model when forward modeled that any differences fall in the model null space. A null-space discriminating ratio (“NSDR”) is defined, for example as the peak normalized difference of the two related modeled electromagnetic field data sets. An area coverage display of NSDR values (6) allows determination of such additional data as may be needed to distinguish the false positive body, and a survey design is developed accordingly (7). Reduction of the number of variables affecting the area coverage displays is a key feature of the method.Type: GrantFiled: April 2, 2008Date of Patent: May 1, 2012Assignee: ExxonMobil Upstream Research CompanyInventors: Scott C.

Patent number: RE41829Abstract: A method for seismic exploration using nonlinear conversions between electromagnetic and seismic energy, with particular attention to the electromagnetic source waveform used. According to the invention, seismic returns from a source waveform are correlated with a reference waveform, with both waveforms custom designed to minimize both correlation side lobes and interference from linear electroseismic effects. A waveform element is selected which may be sequenced by a binary or similar digital code embodying the desired custom design to generate an input sweep with the needed depth penetration and noise suppression. Correlation of the seismic response with the reference waveform in a data processing step mathematically aggregates the seismic response from the input sweep into a single wavelet. Preferred binary digital codes include prescribed variations of maximal length shift-register sequences. Also, an apparatus for generating the desired waveforms.Type: GrantFiled: August 5, 2004Date of Patent: October 19, 2010Assignee: ExxonMobil Upstream Research Co.Inventors: Scott C.
