Seismic Campaign Geothermal Energy the Netherlands (SCAN): An Analysis of Test Line Seismic Data Quality

Summary Seismic Campaign Geothermal Energy The Netherlands (SCAN) was undertaken to fill the gap in subsurface data throughout the center and southern parts of the country. SCAN comprises of 2D seismic acquisition, re-processing of vintage data and, eventually, drilling exploration wells. Within SCAN, a test line was shot to determine optimal acquisition parameters. An investigation was performed into the quality of the test line seismic data, and its relation to acquisition parameter (e.g. shot depth, charge size) and external circumstances (e.g. wind, traffic). Seismic data shows a trend in shot quality that does not correlate to (a combination of) acquisition parameter(s) and is therefore likely controlled by the subsurface. Locally, however, data quality convincingly benefits from increasing charge size and shot depths. Noise mitigation can be performed through shooting with low wind speeds and keeping distance between source of noise and receiver. The south(eastern) part of the Flevopolder contains a source of high-frequency attenuation. Several culprits have been identified, the most likely being a thickened Eem-formation.
