Summary:
There has always been continuous geophysical technological advances on multiple fronts, both on equipment (e.g. computing), the way of working (e.g. night operations), and processing algorithms. In PDO’s experience the major catalysts for change are twofold – collaboration with vendors, and motivated geophysicists. These have allowed us to experiment with different techniques without fear of failure. The aggregate of these developments now enables dramatically increased channel counts, which in turn are funded by a step-change in productivity, for the requisite capex. The ultimate result has been the potential for acquisition of properly sampled data in both source and receiver domains. Wide azimuth acquisition with adequate in-line and cross-line offsets, together with previously unthinkable fold are providing a new era of imaging. Further, coverage over very large areas with fast turn-around is nowadays a reality.
