Abstract
Summary Azimuthally-dependent P-wave attributes responses can be related to open fracture orientation and have been suggested as a geophysical tool to identify fracture orientation in fractured oil and gas reservoirs. A field experiment conducted over a fractured reservoir in Algerian basin provides data for test of this attributes. A VSP Walkaround survey data are collected and three component receivers were used. The orientation of fractures in this reservoir was previously obtained using shear wave splitting from P-S waves from the same dataset In this work, we use the compression waves data to calculate the azimuthal variation of some P-wave attribute responses, as well as the travel time, incidence angle, amplitude and the instantaneous frequency to extract information that can be confirm those obtained by the shear-wave splitting study. Results obtained from the azimuthal P-wave attributes analysis corroborate with these obtained using P-S converted waves. This study is an example of the high potential of P-waves to detect fracture effects on seismic wave propagation.
