Isolation of Domanic reservoirs as a result of the carbon-oxygen logging

The well-known fact about Tatarstan is that reserves depletion from nonshale reservoir rocks on the territory of the most fields critically increases. New tasks are usually set before geologists for maintain production and keeping reserve base: searching for oil deposits and field work in unconventional reservoirs. Data interpretation of C/O logging of overlying section of the Domanic deposits is described in the article (fields of the Republic of Tatarstan are used as the example).
Materials and methods
C/O logging as the method of identification dropped coverage and field management.
Results
The method of isolation reservoirs of Domanic deposits.
Сonclusions
Scientific investigation on unconventional reservoirs is on the stage of developing and improving. Tracking well log of the Domanic deposits (the Famennian), seismic data and data interpretation of C/O logging, petrophysical investigations of core material, makes it possible to state that the Domanic deposits are wells, extended in space. The Domanic deposits are not monitored by configuration and data of deformational traps and are not limited by edge and bottom waters (no OWS). Belts of consolidated formations are considered to be pool boundaries, horizontally and vertically; pointed out using C/O logging. For a more accurate picture of the deposit size, it is necessary to conduct GIS techniques INGK-C and laboratory tests of the core. Coring from prospective intervals should be carried out on the full face of the deposit.
