The Impact of Geothermal Energy on Natural Gas Production
Natural gas is besides from crude oil and coal one of the most important energy resources. However, during the depletion of a reservoir, the occurrence of liquids, e. g., water, condensates, is a well known phenomenon worldwide. Depending on the gas composition and the physical boundary conditions (pressure, temperature), water and/or…
