    Abstract: An undercutting tool for producing an undercut in a bore, the undercutting tool comprises a tool body, which can be at least partially inserted into the bore that is to be undercut, at least one wedge moveably attached to the tool body and having at least one cutting surface. The at least one wedge is displaced outwardly by centrifugal force due to rotation of the undercutting tool. The at least one cutting surface is adapted to cut into the bore that is to be undercut as the at least one wedge is displaced outwardly.

    Abstract: Expandable reamers for enlarging wellbores include a tubular body and one or more blades configured to extend and retract. A sleeve member within the tubular body has open ends to allow fluid to flow therethrough. A fluid port extends through a wall of the sleeve member. A restriction member within the sleeve is movable between first and second positions. In the first position, fluid flow through the downhole end of the sleeve is generally unimpeded, and fluid flow through the fluid port is generally impeded. In the second position, fluid flow through the downhole end of the sleeve member is generally impeded, and fluid flow through the fluid port is generally unimpeded. The restriction member may be configured to move responsive to changes in the rate of fluid flow through the sleeve member. Methods of using such reamers are also disclosed.

    Abstract: The invention relates to an overdrilling head (1) for displacing ground surrounding a pipe, comprising an elongated base body (2) that is suitable for at least partially embracing the pipe to be overdrilled and has a front end (3) and a back end (4). At the back end, a connecting means (5) is provided for connecting the base body (2) to an element of a heading work, with which the overdrilling head (1) can be driven forward. At the front end (3), a front surface optionally comprising a plurality of individual surfaces (6, 7, 8, 9) is provided, extending from a rear part of the front surface, in which at least one point (P1) on the front surface is located on a first plane (E1) that is arranged perpendicular to the longitudinal axis of the base body, to a front part of the front surface, in which at least one point on the front surface is located on a second plane (E2) arranged perpendicular to the longitudinal axis of the base body. In the longitudinal direction (L) of the base body, the second plane (E2) is located further forward than the first plane (E1), and the point (P1) in which a line originating from the connecting means and disposed parallel to the longitudinal axis of the base body intersects the front surface is not located on the second plane (E2).

    Abstract: A well perforating gun having stress relieved scallops. A well perforating gun includes a gun body having at least one scallop formed in a sidewall of the gun body. At least one stress relief element, such as a radius or chamfer, is formed between the scallop and an outer surface of the gun body. The stress relief element may extend in a plane which extends longitudinally or laterally relative to the gun body, and may intersect a centerline of the scallop. The stress relief element reduces stress in the gun body due to a pressure increase in the interior of the gun body.
