Abstract
The main aim of this research is to determine nearest and acceptable predicted permeability value obtained from wire line logs compared with those values coming from core sample analysis within two wells belonging to two domes from small giant Bai Hassan oil field, using irreducible water saturation graph method. This work consists of three main parts: Part one is well logs analysis, which involves determination of Archie petrophysical parameters, porosity corrected from volume of shale, water saturation and irreducible water saturation. The second part is predicting permeability using irreducible water saturation from well log analysis and comparing the estimated values with the data of permeability that measured from core sample in BH-20 and BH-53 well. The last part was using SPSS statistic software to determine the factor that can give the very nearest and acceptable values, these values uses to estimate real permeability for another wells distributed on each dome of the small giant Bai Hassan oil field. Excellent correlation obtained (R2=0.978 in BH-20 and R2=0.9945 in BH-53) between estimated permeability values based on irreducible water saturation and permeability that got from core sample. The result of statistical method (SPSS software) is:
K Core = (K Predicted*1.040)-3.363 (BH-20) [Kithka Dome]
K Core = (K Predicted*1.030)-3.359 (BH-53) [Daoud Dome]
