ABSTRACT:

Tectonic relationship between the Pre-Apulia Platform and the Albania Thrust Belt (Orogeny), as well as its impacts on hydrocarbon prospects nearby have been geological issues for times. But, recent exploratory works have provided invaluable information on tectonic setting and spatial position of some hydrocarbon prospects. Consequently, it's possible to make out the following main tectonic units and hydrocarbon prospect trends:

  • Pre-Apulia Platform represents a big monocline composed of the Cretaceous-Oligocene carbonates that dips gradually north-eastwards under the Orogeny. Few oil prospects depicted in buried carbonate mounts somewhere are not sealed. So, oil has migrated into sandstone beds of Miocene deposits.

  • Albanids and Hellenides Thrust Belt represents an orogenic assemblage composed of evaporite and carbonate formations of Mesozoic, as well as flysch, flyschoids and premollases of Cenozoic that build up two main tectonic stages and several tectonic zones. Several oilfields and oil prospects depicted in the target of Cretaceous-Eocene limestone are sealed by flysch.

  • Per Adriatic Depression filled up with molasses deposits of the Messinian and the late molasses of the Pliocene that set up the Upper tectonic Stage and lie unconformable on both, the Platform and Orogeny.

Sandstone beds of Messinian and Lower Pliocene have been the main target of exploratory works. Consequently, there are few oil and gas fields discovered, as well as few gas prospects depicted so far.
