Analiza zmienności prędkości filtracji węglowodorów w gruncie metodą ANOVA
(2008) Fąfara, Zbigniew
The results of analyses of influence of selected factors: ground model, type of used hydrocarbon mixture and level of moisture in the porous space of the ground-water medium on the vertical filtration rates of oil products in the ground obtained in laboratory condition are presented in the paper. A method of one-factor variance analysis method was applied. The calculates were realized at two stages. In the first stage data were selected in view of information about grouping levels which correspond to definitely differentiated filtration properties of the ground models and properties of oil products. In the second stage all these data were accounted for. Similar conclusions were obtained in both cases. They revealed a strong influence of selected factors on the defined variable.

Modelowanie procesu migracji i akumulacji węglowodorów w basenie naftowym rowu lubelskiego
(2006) Zawisza, Ludwik
Analysis of pressure and water chemistry data from the Devonian and Carboniferous formations of the Lublin Basin indicates that two regional fluid flow systems are operating within this basin. The Devonian basin is the juvenile basin with compaction-induced centrifugal, lateral water movement (before invasion by meteoric waters), and may be classified as prospective. The Carboniferous basin is an intermediate basin with centripetal water movement, artesian properties and invasion of meteoric water. In this paper author presents the hydrodynamic modeling of hydrocarbon migration and accumulation in the Lublin Basin, Poland. The pressure and water chemistry data have been used to identify hydrocarbon traps within the Devonian and Carboniferous sequences.

Wpływ właściwości gruntu na migrację węglowodorów na podstawie badań laboratoryjnych
(2005) Fąfara, Zbigniew; Rychlicki, Stanisław
The mechanisms connected with migration of petroleum hydrocarbon substances in soil and influence of soil properties on their character are presented in the paper. Laboratory measuring stand are described, and exemplary results migration ethyline and car fuel in two models of soils: sandy and sandy-mud, after spilling hydrocarbons on surface are presented. The results have been used for qualitative and quantitative analyses of the influence of properties of soils on the course of hydrocarbon substance diffusion. The rate of vertical filtration of individual contaminant substances in the considered models of soil at various depths, where measuring points were located, was assessed. With the received values it was possible to show the influence of the absolute permeability ratio and primary moisture retension curve on the character of migration. A relationship of coverage and velocity of horizontal dispersion of hydrocarbons with parameters of soil has been indicated.
