ABSTRACT
Mishrif Formation (Late cenomanian- Early Turonian) is considered as a main
reservoir in Nassirya oil field, south of Iraq. Five wells, namely NS-1, NS-2, NS-3, NS-4,
and NS-5 are selected to study reservoir and facial characteristics of formation and try to
correlate them with oil field production. Thirty seven thin sections of Mishrif formation
were supplied from S.O.C., additional fifty seven thin sections were prepared to enhance
results.
Upper and lower contact boundaries of Mishrif formation were determined using
electrical, porosities, and Gamma ray logs. The Formation is subdivided into two main
lithological units separated by impermeable unit depending on self potential and
Gamma ray logs. Lower lithological unit is also subdivided into two reservoir units
separating by barrier rocks.
Peterophysical properties of formation under study were determined using
different well logs. Porosities are calculated via (sonic, neutron, and density) logs. It is
clear that the primary porosity of formation represents dominant one and the secondary
is of rare. Calculations of water and hydrocarbon saturations show that the Mishrif
Formation contains different quantities of water, residual oil, and mobile oil
hydrocarbon. Lithology, mineralogy, and matrix of formation are limestone with little
dolomite, calcite, and calcite, respectively.
Seven main microfacies and eight submicrofacies were identified depending on
fauna content. Mishrif Formation were deposited under wide spectrum of depositional
environment starting with open marian at lower part and ended with open lagoon (at
upper part). Diagnsis processes were observed through microscopic examination of thin
sections. These processes includes: compaction, stylolite, newmorphism, cementation,
dolomtization, solution, pressure solution, and mechanical disintegration. These
processes affected of Mishrif Formation and play a role in deterioration and
enhancement of its porosity. Reservoir performance is detected using data of capillary
pressure. Reservoir units are classified depending upon these tests into four grades
(very good, good, medium, and poor).
Oil reserve is calculated using volumetric method and it is found to be equal to
(898) million tons under standard surface conditions.
