Geological modeling using Petrel Software for Mishrif Formation in Noor Oil Field, Southeastern Iraq

Abstract

Petrel is regards one of the most important software to delineate subsurface Petrophysical properties to the reservoir. In this study, 3D Integrated geological models has been built by using Petrel software. The process includes integrated Petrophysical properties and environmental approaches.
Noor oil field within Mishrif Formation in terms of structural geology represents asymmetrical anticlinal fold with direction NW-SE. Porosity and water saturation model have been built. The reservoir was divided into several reservoirs and Nonreservoir units depends on the Petrophysical properties for each zone. In addition,
intact model for the reservoir in terms of porosity and water saturation have been built. MB reservoir unit represents the most important oil bearing unit according to the high porosity and low water saturation are present in this unit. MB reservoir unit in terms of Paleoenvironment which represent the shoal including rudist biostrome. Rudist biostrome buildups comprise the major oil producing reservoirs in the carbonate strata during Cretaceous Period.
