Satellite-derived bathymetry for offshore exploration

EOMAP GmbH & Co.KG + Qatar Shell Upstream International B.V.

In 2010, Qatar Shell Upstream International B.V. re-entered exploration in Qatar by focusing on the relatively deep conventional Pre-Khuff gas. In order to support Qatar Shell with the execution of onshore and offshore seismic programs, extensive use was made of satellite imagery to derived added values products such as shallow water bathymetry, seabed classification and onshore digital elevation models. Mapping the 740 sq km offshore area using satellite derived bathymetry resoluted in significant time and cost savings, and mitigated HSSE risks. The satellite imagery products were revealed as a key technology in aiding the planning and preparation of the seismic surveys.
