    摘要： A downhole tool includes a first portion having a first metal protrusion configured to seal against a first metal surface and a second portion having a second metal protrusion configured to seal against a second metal surface. A ratcheting device includes a first element having a plurality of grooves, and a second element having at least two sets of teeth, wherein one of the at least two sets of teeth engages the plurality of grooves. Additionally, a method of forming a downhole seal includes disposing in a wellbore a downhole tool including an inner tubular, a lock ring, a lower ring, an upper ring, an insert ring, and a deformable element. The method further includes moving a wedge sleeve axially downward with respect to the downhole tool such that the wedge sleeve engages the deformable ring and forces a first metal protrusion on the deformable element into contact with an outer tubular.

    摘要： The side tracking system includes a window mill having a full diameter cutting surface and a reduced diameter tapered cutting surface and a whipstock having a ramp engaging the reduced diameter cutting surface. The materials of the whipstock have a first cutablity and the materials of the casing have a second cutability. The reduced diameter cutting surface contacts the whipstock ramp at a first contact area and the fill diameter cutting surface contacts the wall of the casing at a second contact area. As weight is applied to the mill, there is a first contact stress at the first contact area and a second contact stress at the second contact area. A cutability ratio is the first cutability divided by the second cutability and a contact stress ratio is the first contact stress divided by the second contact stress. The mill cuts the casing rather than the whipstock by maintaining the product of the cutability ratio and the contact stress ratio less than one. Preferably the height of the reduced diameter cutting surface is greater than the height of the full diameter cutting surface. The ramp includes a plurality of surfaces having different angles whereby the rate of deflection of the mill by the whipstock varies as the mill is lowered into the borehole. In particular, the ramp of the whipstock includes two surfaces having steep angles, one steep angled surface causing the mill to punch through the wall of the casing and the second steep angle surface moving the center of the mill across the wall of the casing.

    摘要： An apparatus for finding a pre-existing downhole window includes a body having a deflector ramp and a cavity, and an extendable dog disposed in the cavity, the dog mechanically moveable between a retracted position and an extended position into the pre-existing window. In some embodiments, the apparatus includes an axially moveable sleeve disposed adjacent the extendable dog. A downhole window finding apparatus includes a deflector including a window finding assembly, and a running tool removably coupled to the deflector, wherein the window finding assembly includes an extendable member and an axially moveable sleeve retaining the extendable member. In certain embodiments, a fluid flow path extends through the running tool and the deflector to the window finding assembly. In some embodiments, a shear bolt removably couples the running tool to the deflector and includes a fluid passage fluidicly coupling a flow line in the running tool to a flow line in the deflector. A method of finding a pre-existing downhole window is also disclosed.
