Opis:
This paper summarizes the author's previous studies on the sorption of hydrocarbons in sandy soils. Completed several independent series of measurements for various models of soil. There were used unleaded petrol and diesel fuel as petroleum products. A large amount of collected information allows you to draw some interesting conclusions, which may be the basis for generalizations. The detected regularity can afford to develop a several models that can be successfully used to describe the intensity of hydrocarbon sorption processes in soils. These processes have a significant impact on the hydrocarbon migration in the soil by reducing the pollution zone and extending the time of migration. Inaccurate description of the magnitude sorption capacity will lead to large differences between the actual scenario of hydrocarbon migration in soil and its numerical simulation.

Opis:
Thanks realized in 2011 in a wide range of laboratory investigations of adsorption of selected petroleum products in different models of soil author has an extensive set of experimental data. They lead to a series of qualitative and quantitative analysis. They confirm the generally known fact that the intensity of the adsorption of hydrocarbons strongly depends on some features of the oil products (mainly viscosity) and soil (especially grain). It is possible to fit the regression equation using statistical methods, which permits to estimate the adsorption coefficient of different oil products on the basis of parameters describing the granulation of soil. Those obtained equations are characterized by a high degree of suitability to the experimental data and can be successfully used in numerical modeling of hydrocarbon migration in the soil.

Opis:
The paper presents the results of field and laboratory studies aimed at studying the processes of oil transformation in the soil under the influence of natural biological processes during a two-year period on artificially created old spills. The soil of the study area was characterized as meadow. The high toxic effect of oil was confirmed, which was expressed in the complete extinction of soil flora and fauna. Despite the low oil content in the soil (less than 5%), soil self-purification processes were not observed. Moreover, the high sorption properties of the soil, the violation of the water regime and the lack of aeration led to the “conservation” of oil and significantly slowed down the natural processes of its biodegradation. This was confirmed by a slight change in the content of oil products a year after the start of the experiment, as well as the presence of free oil in the pore space of the studied soil.

Opis:
In the Radlin Rotliegend gas field (southwestern Polish Lowlands, Fore-Sudetic Region, Poznań Depression), modelling and reinterpretation of seismic data combined with surface gas surveys (free gas method) help identify "gas chimneys" and locate pathways of vertical migration. An almost impermeable Zechstein evaporite cover reduces the stream of vertical gas migration so that a dry surface geochemical zone occurs at the surface and no seismic disturbances are observed directly above the pay zone of the gas field. The surface gas anomalies form a halo-type pattern surrounding the gas field. The majority of surface hydrocarbon microseepages from the subsurface agrees with the seismically visualised geological structure. The belts of surface gas anomalies and the dry zones separating them run along the strike of Permian structures and faults. Vertical pathways of gas migration are recognisable as zones of seismic discontinuity and chaotic distribution of distinct reflections and diffracted waves. Seismic "gas chimney" effects coincide with surface hydrocarbon gas anomalies. Particularly, they appear above the upper terminations of faults disturbing the Zechstein deposits. The faults create the main a venues for secondary vertical migration of gas from the reservoir to the surface. "Gas chimneys" are observable in a shallow zone above the Muschelkalk (Tm) where higher gas saturation of more porous rocks produces a seismically traceable velocity effect.
