PROCESS FOR PRODUCING NATURAL GAS AND NATURAL GAS CONDENSATE FROM UNDERGROUND GAS CONDENSATE DEPOSITS AND FREE-FLOWING COMPOSITIONS (FC) FOR USE IN THIS PROCESS

摘要

The present invention relates to a method for the recovery of natural gas and/or natural gas condensate from a subterranean gas condensate reservoir, which contains a gas mixture having retrograde condensation behavior, comprising at least the following method steps: a) sinking at least one production bore into the subterranean gas condensate reservoir and recovering natural gas and/or natural gas condensate from the subterranean production well by means of the at least one production bore; b) injecting a flowable composition (FZ), which contains water, urea and at least one metal selected from the group consisting of magnesium, aluminum and calcium, through the at least one production bore into the subterranean gas condensate reservoir; c) inserting an idle phase, in which the urea contained in the flowable composition (FZ) is hydrolyzed and the at least one metal is oxidized; d) recovering natural gas and/or natural gas condensate from the subterranean gas condensate reservoir by the at least one production bore.
