mechanisms and elastic-compressing effects of the geotectonic (neo-
tectonic) nature (Anikiyev, 1964, 1977; Pressure…. 1987; Durmishyan,
Muradian and Rachinsky, 1976). The epigenetic mechanisms are associ-
ated with the inflow into reservoirs' pore space of additional fluid vol-
umes from the underlying sediments. This is supported by mud volcano
activity in the Kerch-Taman zone associated with the Jurassic-Lower
Cretaceous sediments (Kucheruk and Ozerny, 1987; Lagunova, 1973;
Ozerny, 1981).
Geological conditions of the abnormal pressure manifestations in
the
Paleocene-Lower Eocene
reservoirs suggest for the Kerch area that
AHFP models have elastic-relaxation neotectonic nature and epigen-
etic component associated with the injection of high-pressure Mesozoic
fluids (Moshkarev, Fontanov, Slyusarev, Gornostayev and some other
prospects; excess pressure 15.2-25.6 MPa, abnormality factors = 1.53
to 1.87: Durmishyan, Muradian and Rachinsky, 1976; Kucheruk and
Ozerny, 1987; Ozerny, 1981). Formation pressure in the eastern trough
