Patent number: 9903968Abstract: Embodiments of non-uniformly spaced seismic receiver arrays and associated noise removal techniques are disclosed. In one embodiment of a method of seismic data acquisition, a plurality of seismic receivers may be positioned in an array having a plurality of regions, each region in the array having a respective average spacing between seismic receivers, with the average spacing in a second region of the plurality of regions being greater than the average spacing in a first region of the plurality of regions that is adjacent to the second region. Seismic data may be acquired utilizing the plurality of seismic receivers, and noise may be removed therefrom.Type: GrantFiled: October 20, 2015Date of Patent: February 27, 2018Assignee: ION Geophysical CorporationInventor: Christof Stork

Patent number: 9658354Abstract: Disclosed systems and methods provide enhanced seismic images through the use of partial image stacking weights that are based on the resemblance between the local partial image and a reference image. At least some method embodiments include obtaining partial images of a survey region and stacking the partial images to produce a reference image. The partial images are then recombined to form an enhanced image, wherein the recombining includes: measuring at each point the reference image's similitude with each of the partial images; and determining at each point an enhanced image value from a weighted combination of corresponding values in the partial images, the weighted combination using weights derived from the reference images' similitude at that point to each partial image.Type: GrantFiled: November 7, 2011Date of Patent: May 23, 2017Assignee: LANDMARK GRAPHICS CORPORATIONInventors: Stefan M. Compton, Christof Stork

Patent number: 8358562Abstract: Methods and apparatuses are disclosed for replacing the individual receivers used with a seismic interferometry process with an array of seismic receivers and then manipulating the array data in order to measure and modify the typical non-uniform directionality function of the background seismic energy. The non-uniform directionality function is a significant cause of noise with seismic interferometry. Furthermore, the array of receivers may be used to significantly enhance the preferred reflection energy and damp undesirable near surface energy. The directionality function may be modified by using an array of receivers for the virtual source location of seismic interferometry to measure the non-uniform directionality function, generating multiplication factors, and applying the multiplication factors to convert the measured directionality function into a desired directionality function.Type: GrantFiled: August 21, 2009Date of Patent: January 22, 2013Inventor: Christof Stork
