An analysis of the work conditions in the Bóbrka-Rogi field over the 100 year history of its exploitation
(Wydawnictwa AGH, 2017) Wojnar, Albin; Rybicki, Czesław
The Bóbrka - Rogi oil reservoir belongs to oldest reservoirs in Poland. The handmade well named Franek was created by Ignacy Lukasiewicz in 1853. It is currently the object about the historic museum. The accumulation appears in the anticline structure of the Bóbrka fold. As result of study of geological data, this fold has four secondary structures forming separate longitudinal blocks. Moreover transverse dislocations cross the Bóbrka structure on the row of separate deposits. Oil appears in four levels of Ciężkowice sandstones and in layers of the "czarnorzecki" sandstone. The level of the first Ciężkowice sandstone contains oil on the east from the Wietrznianka fault, II level of the Ciężkowice sandstone is oil-bearing within the Wietrznianka fault on the west, up to the Rogi fault on the east., III level of the Ciężkowice sandstone is oil-bearing from the Rogi fault on the east to the Bóbrka fault and partly outside it on the west, IV level of the Ciężkowice sandstone contains oil-bearing horizontals to the west from this block to the fault of the TPS mine. The sandstone Czarnorzecki contains oil-bearing horizontal to the west from the fault of the Jasiołka river. The reservoir belongs to the stratified type in the anticline structure it is shielded lithologically and partly tectonically by dislocations or overthrusts. As it gets out of data of geologically of deposit since the discovery of the deposit one got out of him above 1 200 thousand t of oil and 190 million nm3 gas. The surface of the mining district carries out approx. 2.5 km$^{2}$ . Authors on the basis archival data made the analysis the previous exploitation this reservoir and the evaluation of perspectives of his continued existence with the regard of the possible revitalization of the wells.

Analiza geologiczno-złożowa gazu ziemnego na strukturze Draganowa
(Data obrony: 2014-09-30) Paruch, Justyna
Wydział Geologii, Geofizyki i Ochrony Środowiska
Draganowa deposit is situated in the outer Carpathians, in the silesian unit, in fold Iwonicz Zdroj. Litologicalm stratigraphical and petrophysical properties of formations in the Draganowa 1, Draganowa 2, Zboiska 1, Zboiska 3 and Muchowa 1 in the profile wells are presented on a basis of geological data. The first presented symptoms of hydrocarbons during drilling, results of reservoir tests and qualitative and quantitative composition obtain gas.

Debryty kohezyjne warstw istebniańskich (senon górny - paleocen) na zachód od Skawy
(Wydawnictwa AGH, 2005) Strzeboński, Piotr Andrzej
Cohesive debrites of the Istebna Beds occur within the western part of the Silesian Unit of the Outer Flysch Carpathians. The lithofacies described represents siliciclastic deposits consisting of mud-sandy matrix and scattered, psephite-size clasts. The cohesive debrites originated from sediment gravity flows that were generated on the slope of sedimentary basin by mass-movements and were deposed as aprons by submarine, cohesive debris flows. The highest content of the cohesive debrites (12% of the succession thickness) has been recorded within the Istebna Beds of the Silesian Beskid Mts, the medium in the Beskid Mały Mts (7%) and the lowest within the Moravian Beskid Mts (2%). Most frequently the lithofacies presented occurs within the Lower Istebna Sandstones, while the cohesive debrites with the biggest lithoclasts occur within the top part of the Lower Istebna Shales. The exotic material with dominating crystalline rocks, mostly gneisses, schists and granitoids, makes up 25% of the described deposits (exotic cohesive debrites). Various types of limestones prevail among much rarer clasts of sedimentary rocks and the amount of the limestones distinctly increases going to the east.

Określenie stopnia przeobrażenia termicznego materii organicznej obecnej w łupkach menilitowych w wybranych rejonach jednostki śląskiej w aspekcie występowania gazu niekonwencjonalnego
(Data obrony: 2017-10-25) Stryszowski, Piotr
Wydział Geologii, Geofizyki i Ochrony Środowiska
Celem pracy było określenie stopnia przeobrażenia materii organicznej w warstwach łupków menilitowych, w południowo-wschodniej części jednostki śląskiej. Badania były wykonywane na aparaturze Rock Eval, chromatografie gazowym i spektrometrze masowym, natomiast próbki były przygotowywane metodami laboratoryjnymi. Analiza dostarczyła podstawowe parametry Rock Eval oraz podstawowe biomarkery. Wynikiem analizy było określenie morskiego środowiska depozycji oraz stopnia przeobrażenia od niedojrzałego (Rudawka Rymanowska, Krzywe 218) przez dojrzały (Wernejówka, Turzańsk) do przejrzałego (Łubne, Krzywe, Dołżyca). Badany rejon nie jest perspektywiczny w aspekcie występowania gazu niekonwencjonalnego.

Produktywność karpackich skał zbiornikowych w świetle historii wydobycia węglowodorów
(Wydawnictwa AGH, 2008) Marcinkowski, Artur; Szewczyk, Elżbieta
The paper intends to characterize productivity of oil- and gas-bearing Carpathian sandstones in the area situated to the east of the Wisłok river valley where prospects for new hydrocarbon discoveries are best. It was based on materials from the POGC's files, which contain full documentation of oil, gas and reservoir water production from particular fields and wells. Graphs of the media production, constructed for the Silesian and Skole units, illustrate trends of the production decline in the years 1955-2007. The most fundamental premises for assessment of prospects for new oil-field discoveries result from diagrams that document the productivity of individual oil- and gas-bearing horizons, as well as depth intervals of occurrence of hydrocarbon inflows, shows and traces. Interpretation of the presented data indicates that in the Silesian Unit the greatest oil production was achieved from the Lgota and Krosno sandstones, whereas gas production - from the Istebna Sandstones. In the Silesian Unit, the Kliwa Sandstones of the Menilite Beds represent a predominating productive series, the sandstones are characterized by the best reservoir properties over the whole analyzed area.

Zmiany średniej refleksyjności witrynitu uwęglonej materii organicznej w warstwach istebniańskich jako przykład tektonicznej ewolucji płaszczowiny śląskiej (zachodnie Karpaty fliszowe)
(Wydawnictwa AGH, 2009) Syrek, Magdalena
Organic matter in the Istebna beds occur as dark laminas in sandy mudstones. Coalification degree of organic matter in the Istebna beds is related with orogenic period of the flysch Carpathians. There is no correlation with age of rocks and subsidence processing started during Paleogene. Higher values of vitrinite reflectance in southern part of Silesian Unit have been noticed.
