A stop collar includes an annular body and a gripping member. The body includes an outer surface and an inner surface. The body defines a window extending from the outer surface to the inner surface. A portion of the inner surface has a diameter that decreases proceeding toward an axial end of the body. The gripping member is positioned at least partially within the body and in contact with the inner surface. The gripping member is at least partially aligned with the window when the stop collar is in a first state. The gripping member moves toward the axial end of the body when the stop collar actuates into a second state. A diameter of the gripping member decreases as the gripping member moves toward the axial end of the body.

Provided, in one aspect, is a whipstock. The whipstock may include a tubular having a longitudinal passageway extending along a length thereof, the tubular having a tapered face extending along at least a portion of the length; a support structure movably coupled to the tubular and extendable across the tapered face, wherein the support structure is operable to move from a first closed position closing the longitudinal passageway and a second open position exposing the longitudinal passageway; and a locking mechanism in the tubular for releasably holding the support structure in the first position.

A downhole plug, has an elongate body, the body having a longitudinal axis; a first seal arranged on an outer surface of the elongate body; and a second seal arranged on the outer surface of the elongate body and spaced longitudinally from the first seal. A production tubing for a petroleum well, includes a pipe, at least one side pocket mandrel, and at least one plug.

A method for sealing a side pocket mandrel and hydraulic tube includes moving a sealant dispenser into a pocket of the side pocket mandrel from within a well tubing. The sealant dispenser has an upper seal and a lower seal spaced apart therefrom; the seals are sealingly engaged with the pocket. A space between the upper seal and the lower seal is in fluid communication with at least one port in the pocket. A curable sealant is moved from the sealant dispenser into the pocket and into the tube. Either the sealant is allowed to cure or the sealant dispenser is unlatched from a running tool used to move the sealant dispenser into the pocket.

A casing patch system comprising a base tubular with two anchor/seals coupled to the base tubular and an expansion tool comprising two expansion devices positioned such that upon expansion of the first anchor/seal, the second expansion device engages the second anchor/seal, which allows reduction of the expansion forces due to sequential expansion and reduces the length of the displacement necessary for setting the casing patch, eliminating the need for resetting the thruster, which allows deployment and setting of the casing patch on a wireline. In another embodiment, the expansion device comprises two swages coupled to a shaft at a distance between them approximately equal to the length of the anchor/seal. The swage diameters are selected such that the expansion forces of the anchor/seal by front and back swages are approximately equal, resulting in significantly less expansion force compared to the expansion force necessary for expansion by a single swage, which allows a high degree of anchor/seal expansions unachievable by single swage expansion devices.
