| Abstract | ||||
| The Qasr Field is charchterized by gas production zones . which contains sandstone interbeded with shale, based on the available data represented by geological composite logs and different types of open-hole wireline logs for five wells (QASR-4, QASR-5, QASR-6, QASR-12 and QASR-15). Reservoir distribution maps show that the reservoir net pay thicknes of the Lower Safa Member ranges from 108 -390 ft, the effective porosity map shows that the reservoir porosity ranges from 11-16% , the shale content map shows that the shale content ranges from 3-16%, the water saturation map shows that the water saturation ranges from 5-29% and hydrocarbon saturation varies from 71- 95%. The thin beds have been better defined and reservoir capacity has been maximized in this way by an interpreting method introduced by Thomas Stieber Method . Which enables identification in heterogeneous sandstones of clean sandstone sections. The high porosity sections and thus the good reservoirs generally represent clean sandstone. Quantifying such reservoirs can also lead to highly useful concepts. Knowledge of the sedimentary features is important for determining reservoir geometry and petrophysical reservoir parameters FMI tolls was used for recognition of sedimentary and structural features in microresistivity images. | ||||
