Petrophysical properties and reservoir modeling of mishrif formation at Amara oil field, Southeast Iraq

Abstract EN

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.
