According to the results of reconnaissance for seismic works on 3D technology in south and south-east stock areas of Tarasivsk stock and prospecting for new deep holes №№ 200 Tarasivsk, 107 Vesniansk a specified geological model of Vesnynsk deposit has been made on Upper Carboniferous sedimentations (mirroring horizon of Vа1).
In accordance with a structural map on mirroring horizon Vа1 (С3, Vikoil LTD) south-east stock area of Tarasivsk salt to stock within the limits of Vesnynsk-Karlovsk area are mirrored subparallel to stock by bursting violation and four radial oriented upcasts with amplitudes from 100 to 450-500 m on four block: I is a block of w. № 100/101; ІІ-is a block of hole № 107; ІІІ- hole. № 103; ІV - hole 105/105 demonstrational.
Mining hole № 107 is located in the elevated block separated from the west by radial to stock with upcast amplitude to 500 m from the tomentous block of w. № 103.
The features of gaz and condensate beds are considered and their geological description is given.
Thus, the results of the bore drilling and test of mining hole № 107 prospecting the industrial gas-bearingness of productive horizon of К-3 (С32) have been analyzed.
Mining hole № 107 opened the absolutely new type of gas and condensate beds in which there is:
– absence of general gas-water contact and, accordingly, elementary, base type of deposits;
– absence of quasiviscous high base type in a roofing bed;
– base type of beds in the combined unroof traps.
