| Abstract | ||
| This article focuses on two aims the first one is to define and modeling rock types of Zubair formation in Basrah and the second one is to modeling the petrophysical properties of Zubair formation. Accurate methods have been used to achieve these aims. The rock formations of the Zubair oil field was analyzed and important results were obtained from that analysis, then 4 rock samples from the reservoirs in the Zubair formation have taken at different depths at different temperature, pressure, and rock type. We used Mercury Injection and Gamma-ray Logging to determine and calculate the porosity of these rock samples, also we used deep autoencoders in borehole image logs to determine and calculate permeability. At "Mercury Injection" Method, the results of this study have suggested that the estimated accessible porosity has been considerably decreased in the case of implementing new corrections on the MICP (i.e. Mercury Injection Capillary Pressure) test data. From the “Gamma Ray “method we found that the level of the gamma-ray has been assumed to be associated with the size of the grain. We found that the best depth to calculate the properties of sandstone is (650 – 1100 m) underground. We found that the best depth to calculate the properties of shale is (1300 – 1650 m) underground. | ||
