Oil deposits of Czechia are confined to the Vienna - Moravia oil and gas-bearing province. The deposits are distributed over a great number of individual oil-bearing structures and producing horizons situated at the depth going down to 2,800 m. Sandstones of the Middle and/or the Upper Badenian represent the most productive oil-bearing rocks. The largest deposit of this area (Hrušky) whose major part has already been extracted, serves as underground gas storage.

Another region, in which oil is anticipated to occur, lies in the Moravian part of the Carpathian foredeep where oil exploration still continues. The most important accumulations occur particularly in the weathered crystalline and Palaeozoic rocks. Light, sulphur free, paraffin-to-paraffin - naphtene oil prevail in this field. Uhøice and Klobouèky (in the Ždánice region) are the only oil deposits in this area.

Three grades of oil were extracted in 1999 with specific gravity from 856 to 930 kg/m3 at 20° C, 20-33° API and with content of sulphur 0.08-0.32 % by weight.

Natural gas deposits are genetically associated with formation of oil. The deposits are mostly located in south Moravian part of the Vienna basin. Northern part of the basin contains rather oil deposits. Exploited natural gas contains from 87.2 to 98.8 % of CH4, its caloric value is 35.6-37.7 MJ/m3 (dry natural gas at 0o C), specific gravity is 0.72-0.85 kg/m3 (at 0o C) and content H2S is under l mg/m3. The Carpathian foredeep is considered to be a promising area for the occurrence of natural gas. The composition of local gas deposits varies considerably. The Dolní Dunajovice deposit is characterized by high content of methane (98 %), whereas the deposit Kostelany-west contains only 70 % methane and is rich in helium and argon, which can be extracted on industrial scale.

In northern Moravia, specifically between Pøíbor and Èeský Tìšín, the gas deposits are mostly confined to the weathered and tectonically affected Carboniferous paleorelief. The origin of these gas deposits developed close to the top of the Carboniferous morphological elevations has not been explained yet. Ideas about the gas to have originated during coalification of the local coal seams has little support and its origin is rather considered to be connected with the young processes, which led to the origin of natural hydrocarbons. This applies particularly to the gas deposits of Žukov, Bruzovice and Pøíbor. Part of the Pøíbor gas deposit is used as underground gas storage.

Natural gas, of obviously Carboniferous origin and age, is extracted during so-called degasification of coal seams of the Czech part of the Upper Silesian coal basin. Its quality varies considerably depending on the method of extraction and technical limitations related to degasification. Natural gas from the mines Dukla, Lazy and Doubrava goes by 22 km long pipeline to the steel works Nová Hu in Ostrava. The Carboniferous gas contains from 94 to 95 % of CH4.
