Hydrocarbon saturation.
Melting Points of Saturated vs. Unsaturated Fatty Acids; Contributors; Fatty acids are merely carboxylic acids with long hydrocarbon chains. The hydrocarbon chain length may vary from 10-30 carbons (most usual is 12-18). The non-polar hydrocarbon alkane chain is an important counter balance to the polar acid functional group.
When the rock is fully water-saturated (Sw = 100%), the pore size distribution trend is the same as this distribution. If hydrocarbons are present in the pores, the T 2 distribution features would vary depending on hydrocarbon type, viscosity, and saturation (Coates et al., 1999).Chemistry.
