摘要

Many gas reservoirs in the north-western part of Germany have been produced for decades. It has become increasingly challenging to start production from conventionally drilled holes in depleted reservoir sections. This can be due to invasion of fluid into the rock matrix causing near wellbore damage, the necessity to stop fluid losses prior to running a completion, or the reservoir pressure being insufficient for producing fluids back after drilling.
