The oil
and gas prospective areas in northern and
southeastern Bulgaria and the adjacent regions on the
Black
Sea shelf are accepted as a part of the Carpatho-Balkan
oil
- and
gas-bearing province. The peculiarities of the tectonic
structures are conditioned by some specific, mostly collision
processes during the Paleozoic, Mesozoic, and Tertiary.
They are deciphered now with the help of the depth seismic
explorations, and magnetotelluric, thermal, gravimetric,
and magnetic data, in combination with geological mapping
of south Bulgaria. The usual type of seismic data and well
control as well exist in north Bulgaria and the
Black
Sea
shelf zone; some of this information has been published.
Now an attempt is made for a general overview of the three
regions of some parts of the Moesian platform; Fore-Balkan,
Balkan, and Srednogorie region; and the western part of the
Black
Sea megadepression, as well.
Prospects of the Mesozoic and Tertiary sediments in
north Bulgaria have been comparatively well studied, but
questions remain for southeastern Bulgaria and the Black
Sea shelf zone, coming from unresolved problems concerning
the geological structure. Future regional exploration
is expected to discover new deposits in the reef trends of
Paleozoic, Triassic, and Late Jurassic-Valanginian age, and
connected with usual local Tertiary and Mesozoic structures
and vast overthrust structures of the Balkan and southward,
in both the offshore and onshore.
