Wettability and geochemistry of kerogen also significantly affects the fluid distribution within the pore network and impacts the borehole electrical resistivity measurements in organic-rich mudrocks. Low resistivity pays in organic-rich mudrocks have been linked to clay content and graphitization/aromaticity of kerogen at high thermal maturities. However, the impact of kerogen wettability on the resistivity measurements has not yet been studied and quantified. Numerical simulations of effective electrical properties of rocks combined with the outcomes of wettability quantification can be effectively used to quantify the impact of kerogen wettability on electrical resistivity of organic-rich mudrocks. This can potentially (a) improve estimates of hydrocarbon reserves in organic-rich mudrocks and (b) enables reliable prediction of water production.
