Title: George N Aul: Innovator in Subterranean Drilling Technologies
Introduction
George N Aul is a notable inventor based in Richlands, VA (US), recognized for his contributions to subterranean drilling technologies. He holds 2 patents that showcase his innovative approaches to enhancing drilling processes in coal seams and other subterranean formations.
Latest Patents
Aul's latest patents include a process for establishing a clear horizontal borehole in a subterranean formation. This process involves drilling a generally horizontal borehole using a drill pipe, drill bit, and an uphole drilling device. It also includes lubricating the drill bit and pipe by pumping mud down the center of the drill pipe to carry cuttings from the horizontal borehole. The total solids content of the efflux is adjusted to preselected levels and recirculated to create a borehole wall cake. After drilling, the drill bit and rod are removed, and a casing shoe is inserted to maintain a clear path through the borehole.
Another significant patent is for a production and grout liner for methane drainage in subterranean environments. This process seals a degas hole in a coal seam before mining. It involves inserting a perforated liner into the degas hole and pumping grout down the center to fill the hole completely. The perforated liner aids in the extraction of methane gas and ensures a clear path through the degas hole, preventing sloughing or caving prior to grouting.
