COAL RESERVES

Projects

Introduction to Site Selection. Our site selection criteria is based primarily on the availability and quality of coal within the UCG depth window. The secondary considerations are, is there a market for the products produced within a reasonable distance, and are there pre-existing sites for carbon capture and storage near by.

The coal is assessed for various properties including its tenancy to swell when heat, the percentage of ash produced and the amount of water contained within the coal, as these are the main factures that drive the gasification process. The next criteria to be looked at is weather the coal seam is at the right depth and is of sufficient thickness to make UCG a viable prospect.




ACCESSIBILITY TO MORE COAL >>

		The UCG techniques allow far greater qualities of coal to be exploited. Open cast minding is obviously limited to onshore operations. While conventional mining can be used under esturies and the near-shore, it's prohibitively expensive to mine offshore. UCG makes it possible to gain access to the large coal reserves of the Southern North Sea. Access to such coal reserves may extend to availablity of this engery source for the next three hunderd years.



NO NEED FOR MINING >>

		The team at BCG brings together professionals from both the coal and oil industries and applies best practice in 3D seismic, coal characterization, directional and horizontal drilling and high pressure/high temperature well design to exploit the country’s deep coal reserves. The application of advanced oil field technology and techniques will lead to a re-awaking for the British coal industry, which would not be possible by traditional means. As finding oil reserves became more challenging, the industry developed highly accurate methods of finding new fields through the application of 3D seismic survey. The company will employ these advanced techniques to locate the best coal seams and the faulting within the seams. As with the oil industry we will select the most appropriate seismic method for the location, taking account of local populations and wildlife. The company intends to utilize best practice from offshore oil drilling and from onshore coal bed methane operations to construct highly accurate well trajectories that allow the drill bit to follow the seam for maximum coal utilization. Techniques such as coiled tubing drilling, seismic while drilling and well radar will be employed where appropriate.



YEARS OF SUPPLY >>

		Using UCG gives us a huge increase in the amount of coal available to the world, some estimates put the increase as high as six times, current achievable reserves, mean that power from UCG can be around for the next 150 to 300 years, depend on the growth in demand.
