Abstract

Summary

The paper reviews experience of PJSC TATNEFT studying the domanic sediments – tight, low-permeability oilsource rocks of carbonate deposits. To date, the following results have been obtained: - a series of research activities and subject-related studies have been conducted; - reservoir stimulation technologies and methods are tested and implemented at real field conditions; - nine fields have been included in the State Register in preferential royalty category. In the course of these research efforts, TATNEFT has encountered a number of challenges, which can be divided into two groups – geological (deficiency of knowledge from direct study methods; - difficulties associated with mapping decompression zones; - substantial material expenditures required to conduct a set of core studies) And Technological - underway hydraulic fracturing and hydrochloric acid treatments of potential pay zones identified within the domanic sediments by advanced well logging. Success rate observed during 2014–2018 is 63 %. Lessons learned up to date suggest long-term potential and reasonability of activities associated with development of domanic deposits, substantial pilot testing experience has been gained with average success rate of 63 %. However, there are distinct problems related to such activities. Finding solutions to these problems is a critical task for the future years.
