| Abstract | ||||
| This work focuses on the characterization of Rudies Formation at Zeit Bay oil field through integrating the well logging and seismic data. The seismic data was processed and interpreted. Depth structure contour map was constructed for Top Rudies using Petrel (2017.4) Software, the map shows a NW-SE elongated dome intersected by semi-vertical normal clysmic faults, this elongated dome represents the structural trap in the field. Petrophysical evaluation was done for Rudies Formation and the petrophysical parameters were estimated using Techlog (2015.3) Software. According to the petrophysical analysis Rudies Formation is subdivided into two main zones; the first has low GR value (Rudies 1), the second has high GR value (Rudies 2). Rudies1 has an effective porosity ranging from 15.9% to 20.3%, content of shale ranging from 2.5% to 8.1, water saturation ranging from 4.1% to 15.6% and net to gross value ranging from 73.9% to 97.4% where Rudies2 has an effective porosity ranging from17.7% to 21.4%, content of shale ranging from 2.8% to 8.8, water saturation ranging from 7.3% to 19.6% and net to gross value ranging from 68.9% to 87.8%, that means Rudies1 and Rudies2 are very good reservoirs. Rudies Formation seems to be a homogenous reservoir but it is a heterogeneous reservoir that differs both laterally and vertically at its petrophysical characteristics and lithology. | ||||
