Abstract: Recently, the solids of Archaean-Proterozoic age attract more and more attention of oil geologists, especially in connection with possible prospects of oil-bearing capacity. In the Tatarstan Republic territory for >20 years within the program of deep structure study for the express deep wells base drilling which allowed to receive new unique information on crystal base structure and prospects of its oil and gas content was carried out. It should be noted that all deep parametrical, explorative and operational wells of Tatarstan which in a varying degree were objects of KF collectors study can be divided into four categories conditionall. The wells which opened crystal solids of the Precambrian on the maximal depth over 3000 m. The wells which opened crystal solids of the Precambrian on the considerable depth from 200-3000 m. The wells which opened crystal solids of the Precambrian on depth from 50-200 m. The wells which opened crystal solids of the Precambrian on depth <50 m. The third and fourth wells categories are the most numerous, total more than one thousand wells drilled since the base opening in the middle of the last century.
