DATA PRODUCTS AND INTERPRETATION
MAPPING THE NORWEGIAN CONTINENTAL SHELF The Geological Survey of Norway (NGU) has launched an aeromagnetic remapping programme of the Norwegian continental shelf with funding from the petroleum industry and governmental institutions. During the last 2-3 decades, NGU has built up a wealth of experience in the acquisition, processing and interpretation of geophysical datasets from numerous airborne geophysical surveys onshore and offshore Norway. Our geoscientists combine advanced hardware and software tools to process and interpret data, taking pride in careful attention to detail and thoroughness. The NGU geophysics team is backed by sophisticated and totally integrated in-house and commercial software for image processing of geophysical data, map production, 2D/3D modelling, GIS merging and seismic interpretation. NGU provides integrated geophysical and geological interpretations of the potential field data. Gravity and magnetic data are independent of seismic data, both physically and from a measurement point of view. A joint interpretation that combines seismic, potential field and heat flow data produces a synergy that significantly improves the geological and structural interpretation of the shelf. This range of skills and capabilities provides a complete solution to your mapping requirements. Ongoing research and interdisciplinary development at NGU continue to expand the quality of data acquisition and interpretation.

The need for new high-quality data has become real for mining and hydrocarbon exploration. Improvement in the resolution of aeromagnetic and gravity surveys means that they can easily be used for detection and detailed mapping of faults, fracture systems, magmatic intrusions and salt structures throughout the sedimentary section. In addition, potential field data help to better define basement depth, age, structure and lithology. NGU’s most recent acquisitions have demonstrated the necessity of modern data acquisition in order to validate the first order geologic features of the Norwegian continental shelf.

Recent surveys showed, for example, that the Norwegian oceanic domain and the continent-ocean transition zone have been particularly neglected and/or misinterpreted due to geophysical artefacts by poor navigation and inadequate line spacing. NGU proposes to extend its investigation of the Norwegian continental shelf with several ongoing and new projects. The new surveys will provide coherent and important constraints on the regional tectonic, structural and magmatic setting off Norway. NGU holds a cost-efficient, high-quality aeromagnetic acquisition system. The surveys are organised as multi-client projects with a fixed and reduced price for early participants.
