Hydrocarbon Exploration under Kruja Zone in Tirana-Rodon Area, Albania

The region under study includes the half of the northern area of Kruja tectonic zone, partly the Ionian one and the South Adriatic basin, fig. (1). It has continuously been a problematic area as related to tectonic-facial zones particularly to the possibility or no of the continuation of the Ionian zone north of Dumrea salt diapir. The strong overthrust of Kruja zone structures towards west, the presence of the salt diapir and the facial changes of the deposits make up a real difficulty in the clear and one-sided explanation of the relationships between these tectonic units. Based on the studies made as of now and new recent seismic operations, efforts are made, in this study, to further advance the knowledge degree about the geologic-tectonic structure of this problematic region by harmonizing all geologic-geophysical data. The Kruja zone is composed by carbonatics neritic deposits. From tectonic point of wiev, it is composed by some structural ranges. The numerous oil seeps at outcrops and in deep wells have attracted attention for hydrocarbon exploration, so last years a grid dense of seismic lines were carried out. The interpretation results of these seismic data made possible to throw light and to solution more geological problems, like structural form, tectonic style, relation with other units and hydrocarbon migration as well as. The carbonatic sequence of Kruja zone represented with developed tectonic, overthrusted westward and backthrusts in eastern flanks as well as. In this region, the Kruja zone consists of linear anticline structures.
