Abstract
P142 CROSSWELL REFLECTION TOMOGRAPHY 1 JOHN K. WASHBOURNE 1 FRANCESCO MIRANDA 2 MASSIMO ANTONELLI 2 Abstract One practical limitation to the application of crosswell imaging has been that targets are often near or below the total drilled depths of boreholes. In these geometries velocity models generated from direct arrival traveltime tomography suffer from poor aperture at the bottom of and below the zone of direct arrival coverage. The utility of conventional imaging techniques employing these velocity models is thus degraded. In order to overcome limitations imposed by incomplete direct arrival coverage we have applied reflection tomography to both synthetic and
