уровень добычи проявляется обводнением скважин и подением уровня
добычи у другого оператора из-за внутри пластовых перетоков закачи-
ваемой жидкости в процессе заводнения. Поэтому возможность детек-
тирования внутри пластовых перетоков жидкости, закачиваемой через
нагнетательные скважины позволяет корректировать проекты заводне-
ния скважин, реализуемые для дренажа и улучшения фильтрационно-
емкостных характеристик заданного пространства пласта.

ESTIMATION OF WATER SATURATION OF SHALY-SAND ROCKS ACCORDING TO LOGGING DATA BASED ON MODERN MODELS (on the example of the Bulla-deniz field, South Caspian Basin) M.Isgandarov, A.Abuzarova, E.Karimova, A.Humbatov Oil Gas Scientific Research Project Institute, SOCAR Baku, Azerbaijan alihumbatov563@gmail.com Supervisor: M.Isgandarov Keywords: shaly reservoir, water saturation models, reserves
One of the important parameters in the petrophysical analysis of well
logging data is the water saturation of reservoirs, the definition of which gives
an estimate of the volume of hydrocarbons, which ultimately affects the
accuracy of calculating hydrocarbon reserves.
There are many techniques to estimate water saturation from log data.
The most frequently used is the Archi-Dakhnov equation [1,2]. In order to
evaluate the water saturation of shaly-sand reservoirs, a number of modern
models have been proposed that take into account the presence of a clay
fraction, which can contain up to 40% of bound water.
The most common methods to determine water saturation, taking into
account the properties of the clay fraction, is the Waxman-Smits and Dual
Water models [3,4].
The Dual Water Model (1977) is an extension of the concept proposed
by Waxman-Smiths (1968) et al. to account for the effect of ions adsorbed
near the surface of clay minerals. In the "Dual Water" method, it is proposed
