   Source rock analysis and maturity modeling in the Egypt Western Desert (WD) indicates there are multiple mature source rocks. The oils have been generated over a broad range of organic maturities based on molecular characteristics. Secondary alteration mechanisms include water washing, biodegradation, and evaporative fractionation.  Crude oils in the upper reservoirs tend to be most affected by biodegradation and water washing.  Condensates and light crude oils in the oldest reservoirs appear to be the residual phase from fractional evaporation. A statistical “unmixing” algorithm was used to determine end member (EM) compositions and relative mixing proportions for each crude oil sample. Remigration and mixing of multi-phase generation and alteration results in a reservoir fluid from multiple processes with no one reservoir oil being an end member but a mix of relative amounts of each end member. Examination of mixing proportions shows regional trends and changes within different reservoirs of a single field. The crude oil geochemical data and unmixing analysis do not support a simple two source rock scenario but a complex charge history from a single source rock.
