Patent number: 11506010Abstract: A drilling wedge that has, in addition to a normal connector rod, two wings that extend from the sides of the wedge. These wings are angular members that fill much of the space in the larger casing around the wedge. These wings prevent a milling assembly from sliding past the wedge or from moving off to the side, where an exit through the pipe or casing in the wrong place can occur. Instead, the wings help to keep the milling assembly in the proper position on the tray of the wedge to ensure that the milling assembly reaches the proper exit point in the casing. The wings are retracted when the HEW is deployed through the narrower pipe. Once the HEW is properly positioned, the guide cone is extended and the wings are deployed.Type: GrantFiled: March 26, 2020Date of Patent: November 22, 2022Inventors: Robert Harris, Carl Diller, Candice English, John Milne
