| Abstract | ||||
| The discrimination of lithologic and fluid contents has been achieved by cross plotting the log data of two wells encountered in a channel located, off-shore West Nile Delta, Egypt. Cross plotting the log data of the two wells A and B, on the same plot, helped in comparing the properties of the reservoir at different well locations. This has been successfully achieved using depth, Gamma-ray, and P- and S- impedances data. Moreover, the same cross plots were used individually for each well using the Gamma-ray, Resistivity and Density logs as the color code. Logs of well A shows that the reservoir is characterized by clean and blocky sands, fully saturated with gas; while well B is characterized by sands inter-bedded with shale, and filled with residual gas and water. When appropriate pairs of attributes are cross-plotted, the common lithologies and fluid types can be discriminated and provide a straightforward interpretation | ||||
