Title: Walter L. Richards: Innovator in Subterranean Drilling Technologies
Introduction
Walter L. Richards is a notable inventor based in Huntington Beach, CA (US). He has made significant contributions to the field of subterranean drilling technologies, holding a total of 8 patents. His innovative approaches have paved the way for advancements in drilling processes, particularly in the context of methane drainage.
Latest Patents
Richards' 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. The method includes lubricating the drill bit and pipe by pumping mud down the center of the drill pipe, which helps 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 focuses on the production and grout liner for methane drainage in subterranean coal seams. This process involves sealing a degas hole by inserting a perforated liner and pumping grout down the center. The method ensures a clear path through the degas hole, preventing sloughing or caving that could interfere with sealing.
