Abstract: The disclosure of this application is directed to a downhole tool comprising a central element/member and a sleeve that is rotatably and orbitally disposed around the central element/member. The sleeve rotates and orbits around the central element/member responsive to fluid flowing through the downhole too. The disclosure is also related to a method of advancing the downhole tool in a well by flowing fluid through the tool.

Abstract: The present disclosure is directed to a downhole bypass tool that includes an inlet for receiving fluid into a housing of the bypass tool. The bypass tool also includes a flow directing apparatus disposed in the housing for directing fluid to flow into an operational flow path of a vibratory tool. The vibratory tool is at least partially disposed within the hosing of the bypass tool. The flow directing apparatus operates selectively bypass the operational flow path of the vibratory tool such that the fluid bypasses the operational flow path of the vibratory tool and flows out of an outlet of the bypass tool.

Abstract: This disclosure is directed to a method of using a packer having at least two areas of relative rotation. The disclosure is further directed toward a method of using a packer incorporating a jet port, a highly debossed mandrel and/or a J-pin rotatably disposed within a drag block assembly for continuously and redundantly engaging a J-slot area disposed in the mandrel.

Abstract: A packer having at least two or more areas of relative rotation. The packer also incorporates a jet port, a highly debossed mandrel and/or a J-pin rotatably disposed within a drag block assembly for continuously and redundantly engaging a J-slot area disposed in the mandrel. The areas of relative rotation can be between the mandrel and piping above the packer, the drag block assembly and the mandrel, and the drag block assembly and the J-pin.

Abstract: A one-trip, window-milling system method and apparatus is disclosed. The system is particularly useful in thru-tubing applications where the mills are run on coiled tubing in conjunction with a downhole motor. Preferably, the whipstock is run through tubing and set in position. The mill assembly is typically run in after the thru-tubing whipstock is oriented and set. The mill assembly is supported by a downhole motor, which is in turn run-in with coiled tubing. The pilot mill or leading mill is of a particular shape so as to minimize its torque requirements for initiating the window. A wear device, which acts as a guide, is located behind the initial mill and acts with a flexible connector above the subsequent mills in orienting the initial mill into the casing and away from the whipstock. The subsequent mill or mills feature a gradual increase in cross-sectional area along its or their length, also minimizing the required torque for the downhole motor.

Abstract: The present invention provides a disconnect which has the internal integrity to make it as strong as the rest of the drill string. The present invention can disconnect when desired, despite the fact that the apparatus is at that time subjected to significant tensile or compressive loads. The invention allows for disconnection by alternative methods. Accordingly, in one version of the tool, a ball can be dropped or pumped to a seat to facilitate disconnection. In another version of the tool, that may employ an internal wireline precluding the use of a ball, disconnection can be accomplished by compression of a stack of Bellville washers, in response to a tensile force, to release a collet-locking mechanism. Either design features a rotational locking component.
