2nd Underground Coal Gasification Network Workshop

Building on the success of the first South African UCG workshop in 2011 the second one again brought together local and international Underground Coal Gasification (UCG) experts from around the world to discuss a range of issues and the current status of UCG. During the two days 69 participants from Canada and around the world attended the workshop. Over the two days experts in UCG gave presentations on:

• the status of UCG globally and within Canada;
• legal, economic and regulatory issues;
• modelling;
• environmental risks,
• project development, and
• engineering and geosciences.

The presentations are available on the Programme page

Basic UCG Process
The Basic UCG Process has two wells drilled into the coal, one for injection of the oxidants, another to bring the product gas to the surface. Coal has considerable variation in its resistance to flow, depending on its age, composition and geological history, so simply relying on the natural permeability of the coal to transport the gas is generally not satisfactory. High pressure break-up of the coal with water (hydrofracing), electric-linkage and reverse combustion have all been used with success in both pilot and commercial scale operations. The technique is best suited to deep coal seams, 500 metres plus and can be undertaken both on and offshore.
