| Building a 3D geological model from field and subsurface data is a typical task in geological studies involving natural resource evaluation and hazard assessment. In this paper a 3D geological model for Asmari Reservoir in Fauqi oil field has been built using petrel software. Asmari Reservoir belongs to (Oligocene- Lower Miocene), it represents the second reservoir products after Mishrif Reservoir in Fauqi field. Five wells namely FQ6, FQ7, FQ15, FQ20, FQ21 have been selected lying in Missan governorate in order to build Structural and petrophysical (porosity and water saturation) models represented by a 3D static geological model in three directions .Structural model shows that Fauqi oil field represents un cylindrical anticlinal fold which contains number of culminations at northern and southern parts separated by depressions. After making zones for Asmari reservoir, which is divided into 4 zones (Jeribe/ Euphrates and Kirkuk group which includes Upper Kirkuk, Buzurgan member, Lower and Middle Kirkuk) , Layers are built for each zone of Asmari reservoir depending on petrophysical properties. Petrophysical models (porosity and water saturation) have been constructed for each zone of Asmari reservoir using random function simulation algorithm. According to data analyses and the results from modeling, the Upper Kirkuk zone which divided into five layers is a good reservoir unit regarding its good petrophysical properties (high porosity and low water saturation) with high presence of oil in economic quantities. Cross sections of porosity model and water saturation model were built to illustrate the vertical and horizontal distribution of petrophysical properties between wells of Fauqi oil field. | ||
