By data of laboratory research of the core the presence of rocks with low capacitive-filtration properties with crack-pore and pore-crack types in oligocene sediments of the Krosno zone is established. The methane with of it first homologes (ethane, propane, butane) predominate in the composition of migrating paleofluids and it allow to carry a study territory for gas-bearing. It draw a conclusion that prospects of the discovery here new hydrocarbon fields will be concerned predominantly with the gas of packed collectors.
