Deposits

of

Productive

Series

(PS)

have

been

for

a

long

time

considered

to

be

the

main

reservoir

for

the

territory

of

Azerbaijan

and

adjacent

waters

of

the

South

Caspian

Basin

(SCB)
.

During

this

time,

geological

and

geophysical

investigations

in

the

territory

of

the

land

of

Azerbaijan

and

the

adjacent

waters

of

the

Caspian

Sea

have

been

opened

and

at

present

(
44

onshore

and

27

in

the

Caspian

Sea)

71

oil

and

gas

fields

including

and

others

are

under

development
.

Despite

the

long

duration

of

studies

conducted

by

geologists

of

different

specialties

and

areas,

many

questions

still

remain

controversial





Deposits
of PS
as

previously

described

by

many

researchers

deposited

on

a

rough

surface

of

relief

both

within

the

land

area

and

water

area

of

Azerbaijan

part
.
Paleological

map

compiled

by

author


proves these
statements and to a large extent characterize geological setting of Pre
-
Pliocene age
.
According to this map one can see that distribution of
thicknesses both during lower and upper stages of PS in regional plan is in
direct relationship on complexes of
underlying deposits
.

Map of Lower group PS


At the
beginning

of formation of
the

upper
stage
of
PS the
activity
of
vertical

tectonic movements led to
the
fact,
that
waters


of

paleobasin

poured


into


the


territory


of


Azerbaijan



capturing


the


central


and

S
outhern

part


of


Shamaha
-
Gobustan

trough
.

Small
Djeirankechmyaz
, large
Adjinaur


and Kura
bays were formed
within the

Low
Kura depression. On
the North
Adjinaur


bay is limited
by
Greater Caucasus, on

the South by
territory
of

modern
Mingechaur

water
reservoir.
On
the

South
Kura bay is
limited

by
uplifts of Lesser Caucasus
and
Talysh
. Two small bays formed by
delta of

PaleoAraks

and
PaleoBolgarchai

rivers can be found within this bay. Low
Kura bay itself was formed by delta of

Paleo

Kura.
Similar

bays


formed


in

Siyazan


monocline

and

the


adjacent

waters


of


the


Absheron

archipelago
.

S
edimentation

processes

throughout

the

while

age

of

PS

are

characterized

by

a

complex

nature

than

previously

thought
;



2.
It was proved and graphically clarified with which
deposits the conformable and unconformable bedding of
rocks of PS at the underlying complexes is connected;




3.
Maximum

thickness

of

deposit

of

productive

series

without

dip

angles

is

less

than

6000
m
.



The
results of conducted study will allow to correct the
location for location of a more prospective wells for their
drilling within

the

territory

of

Azerbaijan

and

the

adjacent

waters

of

the

Caspian

Sea

and conducting of purposeful
drilling.
