Abstract

An underground gas transport and production system applicable to the process of coal gasification employing a novel single well approach in which air, oxygen or a mixture of these gases together with water (e.g. steam) is pumped from the surface, to supply a gasification process, via the same well casing through which gas produced by the gasification process is transported to the surface. A corresponding underground arrangement is also disclosed which complements the single well approach and its own advantages in terms of increased recovery of syngas by use of an array of delivery and recovery conduits. By providing multiple burn-fronts an averaging effect is achieved which results in a dilution effect and balancing of gas conditions in the coal seam.
