Experimental modeling of abandoned shallow oil wells convergence

Abstract

The paper discusses issues related to inappropriately abandoned production wells in depleted oil field near Hodonín (South Moravia, Czech Republic). The characteristic effects of the well deformation, depending on whether there was a possibility of fluid displacement from the well space were defined on the basis of model experiments. It was proven that in the analyzed conditions, convergence of abandoned wells is not equivalent to their proper liquidation, because the communication of media is still possible, creating a risk of pollution of groundwater and land surface.
