Xstrata and PathFinder applied oilfield technology to construct a pattern of vertical and horizontal wells to degassify a coal mine in Australia. A custom extended reach drilling rig was built, and a mud motor used to drill horizontal laterals of about 12,000 ft at a depth of 500 ft. Pre-job modeling, automated surface rotational controls and MWD surveys reduced risk and improved drilling efficiency.
