Abstract
3D Lithology and reservoir fluid studies based on conventional interpretation approach, such as low Vp/Vs values indicating gas presence have been used to discriminate hydrocarbon fluids. This work was provoked by the emerging trends of noticeable uncertainties leading to drilling of dry wells in the study area. Confirming the physical indicators of hydrocarbon in the reservoirs through the employed method is worthwhile. Well log data of M oil field was investigated with the aim of identifying reservoir rocks through qualitative and quantitative interpretations of subsurface well log data of M oil field through rock properties cros-splots analysis in the select reservoir in the field (M-5000) and to derive elastic rock attributes such as Lame’s parameter terms (λρ and μρ), Vp/Vs, P-Impedance and S-Impedance from available petrophysical data. Rock attributes derived from well logs were combined to produce three major forms of crossplots, which described and characterized the reservoir in terms of fluid and lithology present. The combinations were: VP/VS versus IP, μρ against λρ and IP versus IS. These rock parameters were analyzed in cross-plots space and used to determine which of them constitutes better indicators of pore fluids and lithology. The M- oil field cross-plot analysis indicate the lowest values of VP/VS (2.05-2.40); IP (5600-6300 (m/s*(g/cc)), λρ (16-20 (GPa*g/cc)), and μρ (4-9.5 (GPa*g/cc)). However, the low values of VP/VS, IP, λρ, and μρ, perhaps IS corresponds to hydrocarbon (Gas) saturation within the M- oil field.
