The Polish part of the Baltic region is located within the contact zone between two large geological units: the Precambrian platform and the Paleozoic platform. It comprises the Polish sector of the southern Baltic Sea and the adjacent onshore part of Northern Poland (Western and Eastern Pomerania). The fundamental geological pattern is defined by the Teisseyre-Tornquist Zone, separating the East European Craton from the Paleozoic platform. As a result of exploration activity in the onshore Pomerania region, four oil fields in Cambrian sandstones, seven gas fields in Carboniferous sandstones, six gas fields in Rotliegend sandstones, and eleven oil fields within the Zechstein Main Dolomite horizon have been discovered. The petroleum play of the southern Baltic Sea region and adjacent areas must be considered separately for Eastern and Western Pomerania. In the Peribaltic Syneclise we can only take into consideration organic matter appearing in lower Paleozoic rocks but their geothermal history refers to the period from the Vendian up to the recent. The present extent of the "oil window" in the Upper Cambrian rocks is mainly restricted to the offshore area. Reservoir properties of the "gas window" Cambrian rocks are rather low due to intensive diagenetic processes. Acquisition of gas should be possible by processes of hydraulic stimulation (tight gas). Lower Paleozoic rocks rich in organic matter (Ordovician and Silurian), especially in the border zone of the EEC (Ro >>gt; 1.3%), could be an area of unconventional gas fields (shale gas). The Western Pomerania petroleum play shows two separate source rocks units. The older one embraces Carboniferous deposits with organic matter of terrestrial origin and generated gases accumulated in the Rotliegend and Carboniferous traps. The second petroleum system is located within the carbonates of the Zechstein Main Dolomite (Ca2). This is a closed system, meaning that the source rocks are at the same time the reservoirs sealed by Zechstein evaporates. Hitherto discovered hydrocarbon deposits in the Polish part of the Baltic region have confirmed good perspectives regarding oil and gas hydrocarbon zones. New, conventional and unconventional discoveries remain possible.

Prace poszukiwawcze prowadzone w rejonie Basenu Lubelskiego miały za zadanie w głównej mierze rozpoznanie struktur z możliwą akumulacją węglowodorów w utworach Paleozoiku i Mezozoiku. Prowadzone prace poszukiwawcze nieprzerwanie od 1956 r. doprowadziły do odwiercenia w tym rejonie ok. 240 otworów i odkrycia kilkunastu złóż ropy i gazu ziemnego. Główną skałą zbiornikową są węglany dewonu oraz klastyczne utwory karbonu z wieloma horyzontami złożowymi. W większości odwierconych negatywnych otworów notowano liczne objawy ropy naftowej i gazu ziemnego.

Exploration works carried out in the Lublin Basin have contributed to the identification of the geological structure of the area and detailed investigation of the Palaeozoic and Mesozoic sedimentary succession. From 1956 until now, approximately 240 deep boreholes have been drilled which discovered several oil and gas fields. In Devonian sediments, approximately 520 depth intervals were tested (the statistics does not include production boreholes). In 280 cases, influx of uneconomic amounts of the formation fluid with value occurred. The Carboniferous sequence was investigated by approximately 300 formation tests. About 70% of them yielded significant brine flows with oil and gas shows.

Polish geologist, Dr. Stanisław Krajewski (1890-1968), studied geology and geography at the Jan Kazimierz University of Lwów (Lviv) and geology at the University of Lausanne under the guidance of Professor Maurice Lugeon. He participated in World War I as a Polish Legion soldier. After the war, Stanisław Krajewski worked as a petroleum geologist at Borysław (Boryslav), which was the major petroleum mining center in the Polish Carpathians. He also conducted research on the geological structure of the Flysch Carpathians in terms ofprospecting for crude oil and natural gas occurrences. In 1931, Stanisław Krajewski was employed at the Polish Geological Institute (PGI) in Warsaw for editing and publishing jobs, while not abandoning seasonal geological investigations in the Carpathians, which he continued until the outbreak of World War II in 1939 and later during the wartime. In 1945, he returned to work as a publishing editor at the PGI, and participated in the post-war reorganization of the Polish geology. In the period of 1951-1961, Stanisław Krajewski was a lecturer at the Faculty of Geology, University of Warsaw. In 1953, he became the Editorin-Chief of the newly formed Wydawnictwa Geologiczne, in which he worked until his death, dealing with the history and popularization ofgeological sciences.
