Deep structure and oil potential of the Valencia Trough (western Mediterranean) - contribution of deep seismic reflection profiling
More LessThe Valencia Trough (western Mediterranean) is a NE-trending feature located between the Spanish mainland and the Balearic islands (Figs 1 and 2). Different geodynamic hypotheses have been proposed to explain the origin of the Valencia Trough: (1) an aborted rift representing the southwestern extension of the continental rift system that developed after late Eqcene times in western Europe in relation to the Alpine collision (Tapponnier 1977), (2) a back-are basin associated with the subduction of the Tethys Ocean beneath the Iberian-European plate (Mauffret 1977; Biju-Duval et al. 1979) or (3) a complex basin resulting from the superimposition of an extension affecting the northwestern part of the trough in the late Oligocene-early Miocene, and a compressional event affecting its southeastern part in the late Oligocene-middle Miocene (Fontboté et al. 1990; Roca et al. 1990; Roca and Desegaulx 1992). The structural and therm al development of the basin and, consequently, the hydrocarbon potential may differ if one interpretation or another is considered.

Deep structure in Romania and the related hydrocarbon prospects
Authors M. Ştefanescu and P. PolonicThe oil industry in Romania has been continuously developed since 1857 when production was first officially recorded. At first exploration and production were restricted to surface or very shallow development. Later, as exploration and drilling techniques evolved, attention was focused on deeper targets. Thus, as improved seismic methods provided more and more detailed information on deep structure, it was possible to plan and drill deeper weIls, of which the deepest reached TD at 7200 m (Bäicoi, north of Ploiesti, Fig. 1). As a result of these deep weIls, new oil fields situated around 5000 m deep were discovered.
