SEISMIC SURVEYS In 2015 no seismic surveys were carried out, neither onshore or offshore. This was the first year since the onset of exploration that no seismic data were acquired at all. Since several years there is a tendency to reprocess existing seismic data. However we have observed an increase in reprocessing of existing data. For a long-term overview of seismic data acquisition see annex 8 .

COAL No coal has been mined in the Netherlands since 1974. By then, almost 570 million tonnes of coal had been mined. Conventional mining is not expected to become profitable again in the future but interest has been shown in producing coal bed methane (CBM). Although research has indicated that a large resource of CBM may be present in the coal seams, the economic feasibility of recovering it has not yet been demonstrated. On 1 January 2015 there were five production licences for coal in force. In 2015 there were again no mining activities in the licence areas. A map showing the location of the production licence areas is presented in appendix 6.
