Latest Patents

Chris Sanfelice holds 2 patents related to horizontal directional drilling in wells. His latest patent describes a method and apparatus for horizontally drilling in wells utilizing a shoe assembly at the down hole end of upset tubing. This shoe assembly consists of a fixed section and a rotatable section suspended below it. An electric motor, along with associated batteries and a gyroscope, is carried on the rotatable section, allowing an operator on the surface to selectively rotate and position it to any desired angular location for drilling a hole in the well casing. After cutting one or more holes in the casing, the drill assembly can be removed and replaced by a high-pressure blaster nozzle to bore into the formation zones. The gyroscope enables precise positioning of the rotatable section to the same locations where the holes have been cut. The drill assembly includes an electric motor with an associated battery, a flexible drive shaft, and a hole saw.
