Akçakoca region (offshore) is one of the natural gas producing area in Turkey. The splays of
the North Anatolian Fault, formed during the collision of the Anatolian and Russian plates in
Miocene influenced reservoir characteristics and distribution in the investigated region. Study
of seismic sections and well data, indicating deepening of the area towards NW, show that the
anticlines, reverse – thrust faults and pinch – outs, considered as stratigraphic traps, constitute
principal factors which influenced oil and gas possibilities of the region. The stratigraphic column
of the study area is rather rich in reservoir, source, cap rock contents. Altough Eocene Kusuri
and Cretaceous Çağlayan formation in the upper part of the stratigraphic column are accepted
on good source rocks, further studies reveal & deeper Carboniferous source rock origin for
the natural gas in Akçakoca – 1 well, which has been discovered by TPAO in 1976. The tectonic
elements influencing the oil and gas possibilites of the investigated area, are the anticlines,
reverse – thrust faults and pinch – outs, generated by collision of the Anatolian and Russian
plates.
