摘要： Systems and methods of detecting marine seismic survey parameters are provided. A data processing system can obtain seismic data from seismic data acquisition units disposed on a seabed responsive to an acoustic signal propagated from an acoustic source through a water column. The data processing system can determine from the seismic data, a direct arrival time for the acoustic signal at each of the plurality of seismic data acquisition units, and can obtain an estimated depth value of each of the plurality of seismic data acquisition units and an estimated water column transit velocity of the acoustic signal. The data processing system can apply a depth model and a water column transit velocity model to the estimated depth value and to the estimated water column transit velocity determine an updated depth value and an updated water column transit velocity for each of the plurality of seismic data acquisition units.

摘要： A system and method for summarizing data corresponding to properties of interest on an unstructured grid that includes active cells and inactive cells on an output surface. An exemplary method comprises identifying an aggregation direction through a region of interest of the unstructured grid and identifying at least one active cell along the aggregation direction. The exemplary method comprises assigning an aggregated value for the at least one property of interest to a face of the output surface on a line along the aggregation direction based at least in part on the data corresponding to the at least one property of interest for the at least one active cell. The exemplary method further comprises filling the at least one data hole by identifying at least one face associated with an inactive cell on the line along the aggregation direction and assigning it an aggregated value.

摘要： The present invention is directed to a computer-implemented method for converting a digital image into a multi-dimensional geo-referenced data structure. The method includes pre-processing or preparing a digital image, defining a color map comprising values for the prepared digital image, defining geometry and location values for the prepared digital image, creating a data structure by assigning to each pixel in the digital image a value, based on the closest match in the color map, and an interpolated geometry and location value, based on the geometry and location values; and transmitting the data structure to an interpretation application and creating a multi-dimensional geo-referenced data structure for interpretation.

摘要： A method for use in seismic exploration comprises: accessing a set of seismic data representative of a subterranean geological formation and a subsurface attribute model of the subterranean geological formation; performing a wavefield extrapolation on the seismic data in the subsurface attribute model; applying the time-shift extended imaging condition to the extrapolated wavefields; forming shot-indexed, time shift gathers for each image pixel of the subsurface attribute model from the conditioned extrapolated wavefields; adaptively focusing the gathers; and stacking the adaptively focused gathers; and imaging the subterranean geological formation from the stacked, adaptively focused gathers. The method may, in some aspects, be realized by a computing apparatus programmed to perform the method or as a set of instructions encoded on a non-transitory program storage medium that, when executed by a computing apparatus, perform the method.

摘要： A system and methods for analyzing seismic data are provided herein. The method includes identifying, via a computing device, a representation of a seismic data set (1802) and determining a number of feature descriptors corresponding to each of a number of aggregates within the representation (1804). The method also includes identifying a query relating to the representation and one or more vocabulary definitions relating to the query (1806), analyzing the representation to compute a likelihood that each of the aggregates satisfies the query (1808), and returning a result of the query (1810).

摘要： Methods (600, 1100) and devices (1200) for seismic data processing attenuate noise by replacing an attribute value v(i) of a selected data point (700) i with a weighted average v̂(i) of attribute values of data points j from a window (710) that includes the selected data point i. The contribution to the weighted average of an attribute value v(j) corresponding to a data point j depends on how similar attribute values in the neighborhood N j of the data point j are to attribute values in the neighborhood N i of the selected data point i.
