摘要： The present disclosure provides a system and method for estimating fracture density within a subsurface formation from S-wave seismic data. In one embodiment, the S-wave seismic data is separated into fast (“S1”) and slow (“S2”) data. A computer is used to compute local similarity of the S1 and S2 data and to compute a cumulative time-difference by which the S2 data lags the S1 data from the local similarity. Based on the computed cumulative time-difference, the fracture density of a subsurface formation is estimated.

摘要： Method for aligning converted wave seismic reflection data (PS data) with conventional PP seismic reflection data so that both data types may be used to more accurately image the subsurface for hydrocarbon exploration or field development. Amplitude vs. angle (AVA) or amplitude vs. offset (AVO) attributes of PP and PS seismic data are identified and defined, which attributes are theoretically expected to be in phase and optimize seismic resolution in the data. In one embodiment of the invention, such attributes are calculated (310), then the same horizons are identified in a series of PP attributes and in a series of PS attributes, then the second series is aligned with the first at the horizon locations (316, 320), then a time transfer function is generated and applied to the PS mode data (322), and the aligned joint-mode data are inverted (326) using, for example, AVA attributes.

摘要： The present disclosure provides a system and method for inferring one or more physical property parameters of a subsurface media by inverting converted wave data acquired during a seismic survey. Composite seismic traces are generated at a plurality of survey azimuths (step 609). These composite traces are composed such that their amplitudes are free of effects of subsurface anisotropy. At least one of the generated composite seismic traces is then inverted by isotropic inversion to determine a property parameter of the subsurface media (step 623).

摘要： Method for determining fracture orientation and fracture intensity in multiple fractured layers in the subsurface in a layer-stripping manner. Multi-component, multi-azimuth seismic data are required (31), from which the horizontal, primarily converted wave, components are selected, and these data are further reduced by selecting only the data for which the survey azimuths are either parallel or perpendicular to the general fracture strike (33). If the general fracture trend is unknown, such selective data may be determined by an azimuth-offset scanning process. Layer stripping is performed on azimuth/offset stacks (42) to produce fracture parameter maps (43). All offsets are stacked in those azimuths that produce consistent fracture parameter maps (44), then layer stripping is performed (45) on the stacks to produce final fracture orientation and S-wave time difference maps (46). These maps can be used to produce true amplitude fast and slow S-waves (56).
