    摘要： A system and method for receiving data associated with a set of microseismic events and a fracture network, the data associated with each microseismic event including a location where, and a time when, the microseismic event was recorded by one or more sensors. Each microseismic event in the set may be added to a fracture network in chronological order of the time when the microseismic event was recorded. Each microseismic event may be added by connecting the event to the fracture network by a fracture according to a connection criterion. A stimulated rock volume may be generated that is defined by an iso-surface of points having a constant distance to the fracture network, wherein the fracture network includes a plurality of microseismic events in the set and a plurality of fractures connecting the plurality of microseismic events according to the connection criterion.

    摘要： The instant invention is designed to provide an adaptive approach to removing short-period time/phase distortions within a downward-continuation process that is a key component of seismic migration algorithms. Using techniques analogous to residual statics corrections that are used in standard seismic processing, one inventive approach estimates and removes the effects of short wavelength velocity disruptions, thereby creating clearer seismic images of the subsurface of the earth. Additionally, the instant method will provide an updated velocity model that can be used to obtain further image improvement.

    摘要： A method can include providing seismic data values for a subsurface region that includes a reflector; determining a gradient magnitude value based on at least a portion of the seismic data values; normalizing the gradient magnitude value using a nonlinear normalization equation that includes a gradient magnitude variable divided by a normalization variable raised to a power that depends on an adjustable parameter; and outputting the normalized gradient magnitude value. Various other apparatuses, systems, methods, etc., are also disclosed.

    摘要： A method and system for prospecting for gas hydrates and gas hydrates over free gas is disclosed. The method includes using well log data to form a rock physics model to generate synthetic seismic representing hydrate and hydrate-over-gas models. Spectral decomposition is applied to the synthetic seismic and to field seismic from the prospecting area, forming low frequency narrow band data sets. From mapped potential sands in the field data, compare positive amplitude dominated event in the narrow band field data to the narrow band synthetics for gas hydrates. Compare negative amplitude dominated event in the narrow band field data to the narrow band synthetics for gas or gas hydrate-over gas. From these comparisons, perform modeling to determine saturation and thickness for hydrates and hydrates-over-gas.

    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).
