  • Patent number: 12371963
    Abstract: A section mill having a tubular mill body is attached to a carrier pipe string such as a coiled tubing string. A translatable elongated tubular piston mandrel is positioned within the mill body to receive a flow of fluid from a central fluid bore in the carrier pipe string. The tubular piston mandrel has attached upper and lower pistons respectively positioned within upper and lower piston chambers in the mill body. The pistons move the piston mandrel vertically upward and downward in response to fluid pressure generated by fluid from the tubular piston mandrel. Longitudinally adjustable plungers are attached to the tubular piston mandrel. Cutter shoes are mounted to the adjustable plunger by pivotally attached yoke links. The yoke links and cutter shoes pivot radially inward and outward by upward and downward movement of the tubular piston mandrel and the attached adjustable plungers.

  • Patent number: 11885188
    Abstract: A section mill for milling wellbore tubulars has a tubular mill body, a pivotally mounted mill carrier having a beveled interior profile and a cutter blade on its exterior profile, and a translatable piston having an elongated driveshaft with a radially extending nose cone with a compression spring positioned around the elongated driveshaft. A hook on the elongated driveshaft configured to mate with a corresponding hook catch in the mill carriers maintains the mill carrier in a retracted position. The nose cone of the translatable piston moves upward and downward along the beveled interior profile of the mill carrier in response to fluid pressure. Rotation of the mill body rotates the attached mill carrier and cutter blade for milling.

  • Patent number: 11384616
    Abstract: A multi-string section milling tool has a longitudinally extending tubular body with mill carriers carrying hardened cutters that pivotally extend from a mill window in the tubular body by upward movement of a drive plunger. A downwardly biased piston mounted to the upper end of a flow tube is slidably inserted through a stationary thimble below the piston. The lower end of the flow tube is attached to a drive plunger which is pivotally attached to drive yoke links pivotally attached the mill carriers. The piston and thimble creates a pressure chamber in the milling tool. Fluid pressure in the pressure chamber moves the piston, flow tube and drive plunger upward to pivotally extend the drive yoke links and mill carriers radially outward through the mill window. Cessation of fluid pressure in the pressure chamber retracts the mill carriers.

  • Patent number: 5503437
    Abstract: A hose-coupler made up of a just one component having a main housing section with a female end and a male end. The second female end of the coupler is formed with interior threads, for receiving therein a portion of the male end of the second hose. The main housing section has a compressible portion adjacent to the first male end thereof all the way to the end of the female end. The compressible portion is provided by a plurality of circumferentially spaced-apart linear slots for forming a plurality of clamping jaws or elements, so that, when these clamping jaws are compressed toward each other, the interior threads of the female end of the coupler is forced into locking, threaded engagement with the exterior threads of the male end of the second hose telescopingly received therein. In order to compress the clamping jaws, there is provided a collet rotatably-mounted about the main housing's compressible section.
