Indications of Hydrocarbons

Blocks 4, 5 and 6 have hydrocarbon potential for the following reasons:

• oil traces found in Upper Cretaceous of the Azat-1 well (eight kms from western border of Block 4), and one cubic metre of oil recovered (plus extensive oil shows) from Paleocene in the Shorakhpur-1P well, eight kms further west;
• extensive oil shows in the Upper/Middle Eocene of the Garni-1G well (five kms western of Block 4 border), and oil found in Middle Eocene of Shorakhpur-1P;
• an active oil seep in the Yeranos borehole, SE of Lake Sevan (Block 4);
• active gas seeps in Lake Sevan and some hydrogeological boreholes e.g. Norashen (Block 4);
• gas shows in the Vedi-1T well in the Cretaceous (western part of Block 5);
• heavy, waxy, asphaltic residual oil found within Triassic coals in the Djermanis-4 borehole (Block 5);
• the presence of Permian organic rich, mature, oil- and gas-prone calcareous shales and mudstones in Block 5 (bituminous deposits near Khachik have commercial applications for road building etc.), and
• oil shows in the Neogene of the Nor Arevik area (Block 6); also bitumen in the Shahumian borehole and Coniacian of the Spitakjour River area.
