Progress report van Hemert
The ever increasing world-wide demand for fossil fuels has led to renewed
interest in alternative energy sources. An alternative source for methane is the production of gas from underground coal, referred to as coal-bed methane (CBM). The production of CBM is already occurring commercially in the United States, and many other possible commercial reservoirs exist all over the world.
At first the production of CBM is usually done by directly pumping of all fluids from the reservoir. When primary production of CBM is no longer or not commercially interesting, the enhancement of production by simultaneous gas injection is an option to increase production. This procedure is referred to as enhanced coal-bed methane (ECBM) production.
