Method and system for production of gas and water from a coal seam using well bores with multiple branches during drilling and after drilling completion

摘要

A system for producing gas and water from a gas bearing strata during and after drilling completion. The system includes a directional drilling system, a main bore and pump. The directional drilling system includes a drill and a drill string. The main bore intersects the gas bearing strata and has an upper vertical portion, a lower horizontal portion and a curve portion connecting the vertical portion and the horizontal portion. Waste material collects temporarily until pumped to the surface by the pump installed in the bore.
