چکیده:

Archie found an empirical equation for
consolidated sandstones relating several formation
parameters, such as, porosity and water saturation.
Although Archie equation is usually used by
petroleum engineers, it is not easy to apply it for
carbonate rocks, because formation parameters (m,
n) are functions of changes in the pore geometry,
clay content, tortuosity of the pores, as well as
formation pressure.
The sandstone, limestone and shale existence in
Asmari formation of Gachsaran oil field are
necessitated for determination and correlation of m
and n parameters in Archie equation. The real log
evaluation data of the Gachsaran oil field wells are
used to find a more precise correlation between
formation resistivity factor and formation water
saturation.
