Opis:: Amalgamation of tectonic plates of Southeast Asia occurred in northwestern Vietnam. Six groups of magmatic rocks are related to the tectonic events. The first group corresponds to the major episodes of crustal formation in the South China block, or is linked with the formation of Gondwana. The second group includes granitoids in connection with the collision and formation of the Caledonian-Hercynian folding event. The third group contains Upper Permian ophiolites, as well as the Permian extrusives, formed in intraplate setting, related to back-arcs spreading. The fourth group is related to Triassic Indosinian orogeny, the fifth group comprises Jurassic-Cretaceous intraplate granitoids. Finally, during Cenozoic times, magmatic rocks were represented by alkaline granitoids - the effect of strike-slip faulting related to the collision of India and Eurasia plates.

Opis:: The paper summarizes the results of various laboratory studies of core material, including porosity, permeability, lithological-facies and structural and textural characteristics of more than 1,000 samples of Mesozoic and Palaeozoic rocks. The petrophysical parameters of siliciclastic and carbonate rocks are analysed for the total of samples representing different lithologies (limestones vs. sandstones) as well as for particular stratigraphic intervals (Upper and Lower Cretaceous, Upper Jurassic, Middle and Lower Jurassic, and Palaeozoic). The terrigenous rocks with intergranular porosity and fracture-cavernous carbonate rocks of reefal facies form the best reservoir rocks within the Mesozoic. The terrigenous rocks of fractured and fractured-porous type that are controlled by the fault-block tectonics provide the best Palaeozoic and Ediacaran reservoirs.

Opis:: During the 50-year-long intense petroleum exploration of the Palaeozoic–Mesozoic basement of the Carpathian Foredeep, more than 20 oil and gas accumulations have been discovered. The basic and most important oil-bearing levels in the Mesozoic section are Oxfordian carbonates and Cenomanian sandstones. The Nosówka, Zalesie, Trzebownisko–Krasne, Cetynia, Uszkowce and Lachowice hydrocarbon accumulations and numerous hydrocarbon shows have been found in the Palaeozoic horizons. This paper is focused on evaluation of reservoir properties of the entire Palaeozoic–Mesozoic basement of the Carpathian Foredeep and marginal part of the Outer Carpathians for finding new reservoir horizons. 558 rock samples from 51 wells in the Kraków–Lubaczów area were analysed. The well log results from 20 wells were additionally used for the assessment of petrophysical properties. The results of porosimetry measurements and well logs varied in all discussed Palaeozoic and Meso- zoic basement horizons of the Carpathian Foredeep. The best reservoir properties were estimated within the Jurassic–Lower Cretaceous carbonate complex. Despite great variability, the carbonate rocks display highest average porosity and good permeability values. The variability of reservoir properties is mostly a result of the character of the reservoir-porous-fracture space. Good reservoir properties were also estimated for the Upper Cretaceous carbonate rocks. However, in most of the analysed wells the potential reservoirs were watered. The Palaeozoic complex displays weaker reservoir properties and they mainly refer only to the Devonian–Lower Carboniferous horizon. The Lower Palaeozoic rocks display weak reservoir properties. Their potential is additio- nally lowered by negligible range of occurrence and a small thickness. Generally, the gas- and oil-bearing pro- perties of the analysed zone can be attributed only to the Jurassic–Cretaceous reservoir horizons. The remaining horizons, especially the Upper Palaeozoic complex, are only supplement to the reservoir potential of the area.

Opis:: The geochemical characteristics of the Palaeozoic and Mesozoic strata of the basement of the Carpathian Foredeep depicted the Devonian and Carboniferous source rocks as the best source for hydrocarbon generation. Moreover, the Outer Carpathian sequence was geochemically characterized and proved capable of generating hydrocarbons. The oil-source rocks’ correlations indicated that the source of the condensate accumulated in the Łąkta field, while oil in the Grobla field. Maturity modelling identified Devonian source rocks as they reached a late phase of the “oil window” and, locally, even the “gas window”. The Carboniferous source rock was mature enough to start the generation processes. The generation started in the late Carboniferous, both in the Upper Silesian and Małopolska blocks. The main phase of the petroleum processes took place in late Neogene. The expulsion was observed only in the Devonian source rocks, and vertical migration by fault system in both blocks resulted in oil and gas accumulation in the Upper Jurassic carbonates and Upper Cretaceous sandstones. The petroleum modelling indicated the Devonian source for oil and gas fields in the study area. However oil-source rock correlation also suggests the presence of the Carpathian flysch source for hydrocarbons accumulated in the Łąkta field.

Tarnów–Rzeszów area
SE Poland
Opis:: Two-dimensional modelling of hydrocarbon generation, expulsion, migration and accumulation pro- cesses in SE Poland between Tarnów and Rzeszów was carried out for five source rock horizons, i.e. the Ordo- vician, Silurian, Middle Devonian–Lower Carboniferous carbonates, Lower Carboniferous clastics, and Middle Jurassic. Five cross-sections in the study area allowed the reconstruction of timing and range of petroleum processes. The best source rocks related to the Ordovician and Silurian shales and mudstones reached “oil window” maturity within the entire study area and locally also reached the “gas window”. Generation of hydro- carbons was observed from all five source rocks, but the Ordovician and Silurian source rocks generated two and three times more hydrocarbons than the Lower Carboniferous and Jurassic source rocks, respectively. Expulsion took place only in case of the Lower Palaeozoic source rocks, but the volume of expelled hydrocarbons differed across the area. Hydrocarbons migrated from the Ordovician and Silurian source rocks to the Upper Jurassic (carbonates) and Upper Cretaceous (sandstones) reservoirs or to the Upper Palaeozoic carbonates in connection with the emplacement of the Carpathian thrust belt during the Miocene. Faults formed main migration pathways and hydrocarbons accumulated in structural and stratigraphic traps, located in the vicinity of faults. In places, traps are associated with a deep Miocene erosion surface. The onset of hydrocarbon generation took place during the Neogene, mainly the Miocene, but in the north, generation and expulsion started earlier – at the end of the Mesozoic.
