ABSTRACT:
A method of yielding oil residues or oil containing liquids from contaminated ground layers, includes forming at least two adjacent bore holes in a contaminated ground region, producing connecting passages between the bore holes by loosening and partially rinsing out components of a ground material which surrounds the bore holes and directing a liquid in at least one of the bore holes; applying an underpressure in at least one of the bore holes for aspirating the liquid upwardly, supplying a fluid in at least another one of the bore hole with maintaining a pressure difference between the bore holes, and aspirating in the bore hole under pressure oil separated from the liquid in a raised liquid column or an oil containing cover layer of the liquid column.
