North Sea as geo database

Abstract

A national database of detailed 2D data and 1D ground investigation data is being developed for the Dutch sector of the North Sea. The 2D data mostly comprise interpreted results of high-resolution seismic reflection surveys. The ground investigation data typically comprise cone penetration test (CPT) results, S-wave velocity derived from seismic downhole tests, soil sample descriptions, soil sample classifications and results of geotechnical laboratory tests. The availability of public-domain geodata is rapidly increasing, primarily because of a licensing approach in which the Dutch government provides geotechnical and geological data to tenderers for design and operation of wind farms. The increasing availability of geodata provides new interests and opportunities for the apportioning, development and maintenance of offshore and coastal facilities. This paper describes the contents of the geo database. In addition, it discusses opportunities for testing and validation of new methods for site investigation, as well as integration of geophysical data, CPT results and sample data for state-of-the-art mapping and ground modelling purposes.
