On the Possibility of Joint Development of Gas Reserves from Traditional Collectors and Solid Rocks at Khapchagaysky Petroleum District Deposits

Abstract

General information about using in works for oil and gas a relatively new concept of «hard-to-recover hydrocarbon resources» is considered. The facts showing the existence of the hydrodynamic connectivity of previously identified gas deposits in the Mesozoic and Upper Permian sediments for Khapchagaysky petroleum district dedicated to the eponymous arched uplift of the first order in the eastern part of Vilyui syneclise, are presented. The arguments which can be taken into account in discussions about the possible existence of the largest gas deposit of a massive type in the section of the Upper Permian, controlled by Khapchagaysky uplift are described. A conditional model of a possible joint development of gas reserves in traditional collectors and of predictable resources in deeper horizons of the mantle with solid low permeable rocks are suggested. Recommendations for a wide application of the proposed methodological approach in the sediments of different age and lithology, including oil and gas fields of Vilyuisk region as a whole and beyond it.
