摘要
The invention relates to a method for extracting natural gas and/or natural gas condensate from an underground gas condensate deposit that contains a gas mixture having retrograde condensation behavior, comprising at least the following steps: a) drilling at least one production well into the underground gas condensate deposit and extracting natural gas and/or natural gas condensate from the underground production well through the at least one production well, b) injecting a solution (L), which contains a solvent and at least one ammonium compound (AV) selected from the group comprising ammonium carbamate, ammonium hydrogencarbonate, and ammonium carbonate, into the underground gas condensate deposit through the at least one production well, c) having an idle phase, in which the ammonium compound (AV) contained in the solution (L) is decomposed, whereby carbon dioxide and ammonia are formed, d) extracting natural gas and/or natural gas condensate from the underground gas condensate deposit through the at least one production well.
