Estimation of Initial Oil in Place for Buzurgan Oil Field by Using Volumetric Method and Reservoir Simulation Method

The estimation of the initial oil in place is a crucial topic period exploration, appraisal, and development reservoir. In current work, two conventional methods were used to determine Initial Oil Place. These are volumetric method reservoir simulation method. Moreover, each requires type data whereet al depends on geological, core, well log petrophysical properties while also needs capillary pressure versus water saturation, fluid production static for all active wells at Mishrif studied calculated using neural network technique from 13 cored logged wells. results showed that gave value Place agrees close obtained with percentage different around 2%. However, by offered accurate during good history matching observed as making appropriate adjusting Pc vs. Sw values whole October 1976 until December2020. MB21 unit own most equal 525*106 SM3 MB12 has lowest IOIP 2*106 SM3. Finally, calculation both presented comparing previous study 2013 discovered 1.5% 0.6% respectively.
