| Abstract | ||||
| West El-Burullus area reflected complicated reservoirs consisting of turbidite channels system of the Pliocene shales intercalated with sands forming the Kafr El-Sheikh Formation (FM.). Such turbidites represent a great challenge in accurately determining the existence of hydrocarbons, we have adopted a specific petrophysical evaluation technique using well-logging properties integrated with the modular dynamic formation tester (MDT) followed by Cross-plotting relationships as lithological/hydrocarbon identification. West El Burullus area, it’s proved that have two fields, namely Web and Papyrus fields. Kafr El-Sheikh FM. Three wells (WEB-1, Bamboo-1, and Papyrus-1) are chosen to evaluate the hydrocarbon occurrence in Kafr El-Sheikh FM. WEB-1 and Bamboo-1 well targeted the same reservoir (Web), while the Papyrus-1 well targeted another reservoir (Papyrus). The results proved that Kafr Elsheikh FM. in the wells (Web-1and Papyrus-1) wells contains hydrocarbon with an average net pay of around 16.8m and 15.14m respectively; On the other hand, the Bamboo-1 well does not contain any hydrocarbon that reflects the failure of the well by entering outside the boundaries of the Web Reservoir. All results are matched with MDT. For the Web reservoir, from the MDT plot the water gradient values range from 0.427 psi/ft to 0.448 psi/ft, and the gas gradient value is 0.119 psi/ft. Also for the Papyrus reservoir, the gas gradient values range from 0.099 psi/ft and 0.212 psi/ft as condensate for two different zones. Those types of gases are likely rich gas and thermogenic (may be Miocene sourced) migrated through major faults such as Rashid fault and its successive faults. | ||||
