Abstract

We analyze the orientation of three-component borehole geophones by means of a walk-around VSP carried out in the proximity of the well. We propose a tomographic approach for improving the standard estimation based on hodogram analysis, using the 3D velocity field obtained from surface seismic and well logs. Taking into account the ray bending, the estimate dispersion due to local velocity anomalies can be reduced. This makes more reliable our estimates of fractures orientation and microseism hypocenters when borehole receivers are used in passive seismic surveys.
