|20150331123||System and Method for Adaptive Classification and Filtering for Imaging Diffused Energy from the Earths Subsurface - A method for imaging the Earth's subsurface includes taking summed recordings of signals acquired by a plurality of seismic sensors disposed above the volume in response to repeated actuations of a seismic energy source. A travel time of seismic energy is determined from a position of the source to a selected image point in the volume and from the image point to each seismic sensor. A time-delayed scanline gather is generated from the travel times using a model of spatial distribution of acoustic properties of formations in the volume. A template image of backscattered energy from the image point is generated based on the model. The flattened scanline gather is singular value decomposed. The template image is projected onto the decomposed time-delayed scanline gather. Components from the projection are used to determine signal and interference. Weights are calculated for beamforming of the determined signal component. The weights and delay times are used to cause the focal point of the beamforming to be at the image point.||11-19-2015|
|20150241583||METHOD FOR LOCATING SEISMIC DIFFRACTORS IN SUBSURFACE FORMATIONS FROM A WELLBORE - A method for locating diffractors in subsurface formations includes actuating at least two seismic energy sources at spaced apart locations. Seismic energy is detected in the formations resulting from actuation of the two sources. Signals corresponding to the detected seismic energy are processed to remove components related to direct arrivals from each source. Arrival times of seismic energy in the signals corresponding to energy diffracted from at least one diffractor are identified. The at least one is located diffractor in a plane using the identified arrival times.||08-27-2015|
|20140129150||METHOD FOR ACOUSTIC IMAGING OF THE EARTH'S SUBSURFACE USING NON-LINEAR SIGNAL GENERATION AND DETECTION - A method for seismic surveying includes disposing a plurality of seismic sensors in a selected pattern above an area of the Earth's subsurface. A seismic energy source is repeatedly actuated proximate the seismic sensors. A signal used to actuate the source comprises a linear chirp having a starting frequency and an ending frequency less than twice the starting frequency. Recorded signals are processed to generate an image corresponding to at least one point in the subsurface, the processing includes stacking recordings from each sensor for a plurality of actuations of the source, cross correlating the stacked signals with an expected signal generated by non linearities in the subsurface and beam steering a response of the seismic sensors such that the at least one point is equivalent to a focal point of a response of the plurality of sensors.||05-08-2014|
|20130113489||STATIONARY STAR-SHAPED ANTENNA METHOD FOR MANIPULATING FOCUSED BEAMFORMED, SHAPED FIELDS AND BEAMSTEERED ELECTROMAGNETIC SIGNAL FROM SUBTEL SEDIMENTARY STRATIGRAPHIC FORMATIONS DEEP IN THE EARTH - A method for electromagnetic geophysical surveying according to one aspect of the invention includes disposing a plurality of electromagnetic receivers in a selected pattern above an area of the Earth's subsurface to be evaluated. An electromagnetic source is repeatedly actuated proximate the electromagnetic receivers. Signals generated by the receivers, indexed in time with respect to each actuation of the at least one electromagnetic energy source, are recorded. The recorded signals are processed to generate an image corresponding to at least one point in the subsurface. The processing includes stacking recordings from each receiver for a plurality of actuations of the sources and beam steering a response of the receivers such that the at least one point is equivalent to a focal point of a response of the plurality of receivers.||05-09-2013|
