Deviated and Horizontal Wells Drilling Technology in Coal Seams

Drilling in coal seams becomes more and more popular at the present time, especially due to the fact that coal can be exploited not only by subsurface or surface mining methods but also in much cleaner way – underground coal gasification. The presented article is focused on the modern drilling techn...
