This study focuses on petrophysical characteristics of flysch sandstones in the S-8 well section, located in the western part of the Polish Outer Carpathians (southern Poland). A number of laboratory tests were performed with application of the mercury injection capillary pressure, low field nuclear magnetic resonance, X-ray diffraction and pulse decay permeability measurements. Laboratory tests results were compared with the well logging interpretation. The laboratory analyses were conducted on core samples from ...

This study focuses on petrophysical characteristics of the flysch Krosno Sandstones (Oligocene) from the JordanпїЅw-Limanowa area, located in the western part of the Polish Outer Carpathians (south Poland). This region of the Polish Carpathians is considered to be prospective for unconventional oil and gas exploration. Results of the applied laboratory methods enabled estimation of the crucial geomechanical and petrophysical rocks parameters пїЅ YoungпїЅs modulus, PoissonпїЅs ratio, mineral composition and brittle...

Pore space characterization is an essential element of reservoir characterization, often based on combination of different laboratory techniques. The study concerns mercury injection capillary pressure, low field nuclear magnetic resonance, gas permeability measurements and X-ray diffraction analysis on Miocene sandstones and mudstones. Core samples were taken from several boreholes from the Siedleczka area, which is located in an important gas province of Poland пїЅ the Miocene Carpathian Foredeep Basin (southeas...

This study focuses on the source potential distribution within the Menilite Beds (Oligocene) in the Central Carpathian Synclinorium (Silesian Nappe) in the eastern part of the Polish Outer Carpathians. This region of the Polish Carpathians is one of the oldest petroleum-producing regions in the world, where in several folds plenty of oil and gas fields were discovered. The Menilite series contain the best source rocks in the Carpathians: the Menilite Shales, in which the liptynite group with humic components is a ...

The paper concerns the pores systems characterization of the Miocene mudstone samples provided by mercury injection capillary pressure (MICP) method. This analysis is the progressive intrusion of mercury into a porous structure under stringently controlled pressure. Since mercury does not wet most substances and does not spontaneously penetrate pores by capillary action, it must be forced into the pores by the application of external pressure. The required equilibrated pressure is inversely proportional to the siz...

Paper presents results of 3D modeling and unconventional hydrocarbon resources assessment completed in regional scale on the area of the Eastern part of Paleozoic Baltic Basin. 3D modeling of structural framework, geochemical and petrophysical parameters was performed for Lower Paleozoic strata using Petrel software. The structural model incorporates 8 structural surfaces, 20 faults and stratigraphic information from 84 wells. The model covers an area of 16800 km2 and is divided into 7 zones (500x500 m grid cell s...
