Abstract

On earlier geo-seismic study for hydrocarbon exploration in Albania, every flysch fold “expressed” a<br>carbonate anticline structure in depth, accepting only a small asymmetry scale. But seismic survey and<br>drilled well data gained latter on proved that this interpretation concept isn’t always true.<br>A complex interpretation of geological and geophysical data concerning flysch folds, their asymetry and<br>reflection at top Eocene limestone level, as well as thrusting range have been in focus of many studies on the<br>Albanids Thrust Belt. (Fig.1)<br>Methodology analyses of seismic acqusition, as well as structural modelings before and after field survy<br>have implemented reading and interpretation of obtained seismic information.<br>Modelings based on certain structural and tectonic paterns, as well as on presettled parametres of lateral<br>spread of seismic waves velocities are made through several programs which operate upon certain values of<br>the x, h, v indicaters. (x-coordinate of a point on a reflection horizon in a profile, h-depth point from the<br>seismic datum, v-propagation velocity of the seismic wave from surface to the certain seismic horizon).<br>Realizing the modeling process the generation of a synthetic time section is make possible, where are given<br>only the reflections horizons drowing on the geological model. The utilization of modeling process in<br>seismic interpretation, helps identifying source and type of seismic horizons from all deposits thickness that<br>could be present on a time section. This conclusion is helpful in cases of flysch folds belonging to “flysch<br>thrust belts” in the Albania Thrust Belt.
