The present paper deal with the evaluation of
the petrophysical parameters of Nullipore formation
at Ras Fanar oil field oil field in the central province
of Gulf of Suez through the analysis of well logging
data available for six wells. A comprehensive
formation evaluation has been applied through
number of crossplots and use their out-put parameters
as in put data for interactive petrophysics software in
order to evaluate the lithological constituents and
fluid saturations. The lithosaturation crossplots
indicate that the Nullipore formation consists of
limestone and dolomite with few clay and anhydrite
the lithosaturation crossplots also illustrated that zone
III and II of Nullipore are the main reservoir zones in
the Nullipore.
