Seismic data helps reservoir management

摘要

Oil and gas operators are improving their performance in finding, appraising, developing and managing their reservoirs by combining high-quality seismic data with logging, vertical seismic profiling (VSP) and reservoir production data. Through careful calibration, including rock physics modeling, seismic information can help asset teams more accurately determine reservoir structure and properties, and reduce risk and uncertainty at any stage in the life of a field. Modem 3-D seismic technology has helped reduce the costs of finding and developing oil and gas reserves. It is credited with enabling exploration in deep water, imaging moderately complex geology using prestack time and subsalt depth imaging, and improving early field appraisal and development decisions. Initially, 3-D seismic technology was used primarily as a niche delineation/development tool because it was considered too expensive for exploration. However, the improved imaging and reduced uncertainty it delivered caused it to quickly become a standard tool in exploration. Over the last 20 years, 3-D seismic technology has helped reduce the uncertainty in reserves estimates and enabled operators to locate reserves in increasingly challenging structural and stratigraphic traps.
