... wide and roughly 2,000 ft below the adjacent "mesa" tops. The topographic effects of valley trend, width, and depth on horizontal stress azimuth are important geomechanical considerations (cf. Clark, 1983 33 ; Lorenz et al., 1993 34 ), which can in turn affect hydraulic fracture propagation...

... Abstract Oil is produced from the Manderson Field, in Big Horn County, Wyoming, from a fracture system with possible significant lateral connectivity. So characterizing the fractures in this field is of great importance. Amplitude Versus Offset (AVO) analysis of azimuthally restricted seismic...

... Abstract Seismic data in which anisotropy is observed have been used to detect and characterize the natural fractures, in the Bluebell-Altamont, Utah, field. We show an (azimuth-dependent) amplitude variation with offset (AVO) anomaly in the P-wave reflection seismic, attributable to the gas...

... direction and/or mud weight. Knowing the azimuth of hydraulic fractures will be of great benefit on any producing or injection well. For horizontal or highly deviated boreholes, this information may be required to avoid premature screenout and unexpectedly high treating pressures if the well is fracture...

Velocity measured perpendicular to the direction of fracture strike, where the signal has to travel across the fractures, will be slower than the velocity measured parallel to the strike. As the induced microfractures will strike...

... on the ability to locate perforation shots, indicates a 25 ft (7. 6 m) uncertainty in the location of individual microseisms. This results in a fairly high level of confidence in the determination of the azimuth of the November 1986, hydraulic fracture in the fluvial zone at DOE's Multiwell Experiment Site...
