Patent number: 10481067Abstract: A method and system includes acquiring a seismic dataset while fluids are injected into the subsurface with seismic data recorded at multiple sensor locations. Seismic travel times are computed between sensors and subsurface locations using a velocity model. Travel times and travel time delays between pairs of sensors may be used as input to determine a similarity coefficient associated with subsurface positions. The similarity coefficients are determined using cross correlation, semblance calculations or eigenstructure decomposition. The coefficient values are related to the acoustic response at each subsurface position and may be summed together for each position for comparison with other subsurface positions to determine the position of a fluid front moving through the subsurface. The values may be displayed to illustrate the position of fluids in the subsurface and displayed to show the time variance of the fluid position.Type: GrantFiled: July 7, 2010Date of Patent: November 19, 2019Assignee: Sigma Cubed Inc.Inventors: Brian Fuller, John Marcus Sterling, Les G.

Patent number: 10234580Abstract: Seismic data recorded by subsurface seismic sensors placed in a borehole, such as an oil or gas well, are transformed via a process of upward wavefield propagation to pseudo-receivers at the surface of the earth. The seismic data thus transformed can be processed as though the data had been recorded by the pseudo-receivers at the surface rather than in the borehole where the data were actually recorded. This method accurately accounts for seismic source statics, anisotropy, and all velocity effects between the real receivers in the borehole and the pseudo-receivers at the surface of the earth.Type: GrantFiled: January 19, 2016Date of Patent: March 19, 2019Inventors: Brian Nelson Fuller, John Marcus Sterling

Patent number: 9310506Abstract: A method and system includes determining a subsurface fluid seismic attribute comprising recording a signal at a wellhead related to pumping fracture stimulation fluid to obtain a pressure pulse pump signal. A deconvolution operator is determined from the obtained pressure pulse pump signal. Seismic data are acquired from a plurality of sensors. Travel time differences are computed for the seismic data between the plurality of sensor locations and the subsurface position. Seismic data are deconvolved with the deconvolution operator to obtain a plurality of deconvolution coefficients associated with the subsurface position. The computed travel time differences are used to sum the plurality of deconvolution coefficients associated with the subsurface position to obtain a subsurface fluid seismic attribute at the subsurface position.Type: GrantFiled: June 10, 2011Date of Patent: April 12, 2016Assignee: Sigma Cubed, Inc.Inventors: Brian Fuller, John Marcus Sterling, Les G.
