Item type:Article, Access status: Open Access , Metoda przywracania wydobycia z zawodnionych gazowych odwiertów pakerowych(2006) Janowski, Mariusz; Kośmider, JanuszThe article describes the method of restoring the gas production from the water encroached packer gas wells. The incidents of a loss of the natural gas outflows from the shut down wells, even throughout several hours, have been many times recorded in the industrial practice. The losses resulted directly from the blockage of the gas zone and filling the production string with the reservoir water column exerting its hydrostatic pressure equal to the reservoir pressure. The occurrence of these phenomena in several wells of the Radlin Gas Field made the authors of this publication to search for an effective method to restore the gas production from the water loaded-up packer gas wells. The outcome of the undertaken researches is a method that enables restoring of the gas production from the wells. The effectiveness of the method has been proved in the engineering practice. The result of the treatment of the Radlin 53 gas well is successful restoration of the gas production after four months of the well shut down due to the water encroachment.
