Abstract

Summary

Borehole diameters are typically much smaller than the dominant seismic wavelength and near-vertical borehole geometries do not favor reflection response at a surface acquisition. For these reasons - resolution and illumination - we study the diffraction response from boreholes on surface seismic data. Diffractions from boreholes are observable on surface seismic data under certain relatively mild conditions (sufficient frequency content, signal-to-noise and impedance contrast between the borehole and surrounding rock), and can be used to trace its trajectory. This is the objective of Surface Seismic monitoring While Drilling. In particular, we show that organizing the diffraction imaging in a time-lapse and target-oriented fashion can result in a very efficient and accurate way of monitoring the borehole during drilling.
