Introduction
Donald W Dareing is a notable inventor based in Houston, TX, with a remarkable portfolio of six patents. His work primarily focuses on advancements in drilling and completion technologies, particularly in the field of in situ leach mining.
Latest Patents
One of his latest patents is titled "Triple branch completion with separate drilling and completion templates." This invention provides a method and apparatus for completing multiple branch wells using distinct drill and casing templates. The utility of this invention is significant in the in situ leach mining of deep-lying ore bodies. The process begins with drilling a generally vertical main hole, which is then cased. The casing features an internal indexing dog and specific windows for drilling branch wells. Each window is sequentially drilled out using a drilling assembly oriented by a movable drilling template. After drilling, the assembly is retrieved and repositioned for the next branch. A whipstock assembly aids in accurately locating each branch well. Once all branch wells are drilled, a triple tubing guide is employed to position branch casings simultaneously in the drilled holes, followed by cementing the casings in place.
Another significant patent is the "Method and apparatus to complete horizontal drain holes." This invention outlines a method and necessary equipment for forming horizontal cased and perforated drainholes for underground in situ leach mining operations. After establishing a vertical hole, horizontal drainholes are drilled from below its casing. The orientation for drilling is computed, and a flexible casing is used to encase the drainholes. Special equipment, including a retrievable cement plug and one-way valve, is utilized to manage the flow of cement during the process.
