Geologicheskii Vestnik

The article presents the results of a lithological study of the Visean carbonates at the Trebs deposit, that is located in the Timano-Pechora oil and gas province. A detailed petrographic analysis permitted to identify 13 lithotypes of limestones, dolomites and anhydrites. An analysis of the structure of the void space was carried out using the filtration and capacity characteristics and SEM data, and the influence of secondary processes on the reservoir properties of the rock was considered.
