Petrophysical Properties and Reservoir Modeling of Mishrif Formation at Amara Oil Field, Southeast Iraq

Abstract

Petrophysical properties of Mishrif Formation at Amara oil field is determined
from interpretation of open log data of (Am-1, 2 ,3 ,4 ,5 ,6 ,7 ,8 ,9 ,10 ,11 ,12
and13) wells. These properties include the total, the effected and the secondary
porosity, as well as the moveable and the residual oil saturation in the invaded and
uninvaded zones. According to petrophysical properties it is possible to divided
Mishrif Formation which has thickness of a proximately 400 m, into seven main
reservoir units (MA, MB11, MB12, MB13, MB21, MC1, MC2) . MA is divided into
four secondary reservoir units , MB11 is divided into five secondary reservoir units ,
MB12 is divided into two secondary reservoir units , MB13 is divided into two
secondary reservoir units and MB21 is divided into five secondary reservoir units.
The seve units are separated by seven cap rocks (Bar1,2,3,4,5,6 and 7).A threedimensional
reservoir model is created by using (Petrel, 2014) software for all
reservoir unit. The results show that the first and the second reservoir units represent
important reservoir units of Mishrif Formation. Variables of thickness and reservoir
properties are consider of Amara oil field.
