<p>NA???? DEB:LAV 9/12/77 SEISMIC DELINEATION OF OIL AND GAS RESERVOIRS USING BOREHOLE GEOPHONES A method for delineating an oil or gas reservoir using one or more borehole geophones in the discovery well is disclosed. In this method, both direct and reflected seismic signals are detected by the geophone(s), the downgoing signal is used to deconvolve the upcoming signal, the properties of the reflected signal as received from horizontal profiles of sources are mapped over the reservoir locality, and the reflection signals from a plurality of source positions to a plurality of geophone positions are gathered by common depth-point for analysis and for stacking.</p> |
