DMT completes 3D seismic exploration in Rioja, Spain

ESSEN -- Despite adverse weather conditions, the Essen-based firm DMT GmbH & Co. completed its 3D seismic exploration of conventional natural gas in Spain’s Rioja region on-schedule in March 2013. In the course of the three-month investigation, the experts had to “manage” the challenging topography, particularly where the vineyards that dominate the area’s cultivated landscape were concerned. The project, christened Viura 2012/13, takes its name from one of the region’s white grape varieties.

The project was contracted by UFGEP (Unión Fenosa Gas Exploración y Producción S.A.U.), one of the largest Spanish gas service providers, and its partners Sociedad de Hidrocarburos de Euskadi, S.A., and Oil & Gas Skills, S.A. Over an area of 232 sq km, containing the district capital Logroño and 22 municipalities, measures needed to be coordinated before exploration began. Authorization had to be granted for roughly 60,000 plots of land, 90% of which are privately owned, and dates had to be agreed upon for the 3D seismic work to be carried out.
T
he work was performed from January to March 2013, during which time Spain experienced one of its wettest and snowiest winters of the last decade, making field work more difficult than expected. Seismic waves were produced at nearly 10,000 locations, using specialist vehicles and borehole methods, and were logged at approximately 9,000 points.

A total of 38,520 working hours were needed, and 187,248 km were covered by 56 vehicles to gather and record the seismic data, which will provide UFGEP with precise and reliable information for future activities in the area.
