The Jeribe formation considered the main reservoir, contains gas<br>condensate fluid, has a uniform thickness about 60 m. The reservoir is significantly overpressured.<br>In this study, the 3D geological model for Jeribe Formation in Mansuriya Gas Field is setup<br>by using Petrel. Jeribe Formation represents the most important reservoir in Mansuriya<br>Gas Field. Four vertical wells (Mn-1, Mn-2, Mn-3 and Mn-4) were drilled in Mansuriya<br>Gas Field and used to set-up water saturation and porosity models represented by a 3D<br>static geological model in three dimensions. The main reservoir, Jeribe Formation<br>carbonate, is subdivided into 8 zones namely J1 to J8, according mainly to porosity log<br>(RHOB and NPHI) trend, DT trend and saturation trend. Petrophysical model (porosity and<br>water saturation) for Jeribe Formation was set-up from values of porosity and water<br>saturation using Sequential Gaussian Simulation algorithm. According to data analyses and<br>the results from modeling the units (J1, J3, J4, J5, J6 and J8) are considered as high-quality<br>reservoir units due to the high PHIE, low water saturation and no shale content. Units (J2<br>and J7) are considered as non-pay units because of very high-water saturation. Cross<br>sections of petrophysical model were conducted to show the vertical and horizontal<br>distribution of porosity and water saturation between wells in the field.</p>}, number={1}, journal={Journal of Petroleum Research and Studies}, author={Azeez, Hasan Saleh and Al-Dabaj, Dr. Abdul Aali and Lazim, Dr.Samaher Abdil-Rasool}, year={2020}, month={Mar.}, pages={36-54} }
