Eastern Ukraine has а great potential in exploration of tight gas fields. The most prospective area occupy extreme south-east of Dnieper graben. Territory is characterized by maximum thickness of sediments (15 =18 km) and Devonian salt, nonexistence of regional chemiсаl seal, but has а great potential of gas generation, good catagenetic impermeable bed sealing abnormal seam pressures. Gas in the lower and middle carboniferous trapped in tight secondary fractured porous sand collectors by capillary power unlike to conventional traps where gas trapped in the anticline folds of water-bearing horizons. Accumulations of central basin types occupy а large volume of the territory, covering the whole extreme south-east of Dnieper-Donets graben.

A new scientific method devoted to the development of hydrocarbon deposits in high temperatures (more than 120 degrees of Celsius) is presented. The elements of sedimentary system are transformed by thermomass transfer. The high efficiency of predicting of some specific parameters like abnormal formation pressure or zones of unconsolidation was obtained.

The data on geologic structure of a field, results of 3D method seismic tests and exploratory drilling are cited. Future trends and challenges of the further exploration of the Kobzivske gas-condensate field are considered.
