Annotation:
Carbonate deposits of the Timano-Pechora Basin show a variety of lithologies with different pore types with a wide range of reservoir characteristics. The combination of the complex textural, mineralogical and diagenetic characteristics with the mixture of in situ organic matter and mobile hydrocarbons govern the distribution of the water-wet and oil-wet rock properties. The dominant type of the rock`s wettability is dependent on the specific litho type characteristics of the reservoir rock, as highlighted above.
