摘要： Certain aspects of the present disclosure are directed to tools actuated by pipe swell. A downhole assembly for a wellbore may be provided. The downhole assembly can include a first sleeve and a second sleeve. The first sleeve can expand from a first position to a second position in response to a first pressure applied to the first sleeve. The first sleeve can contract to the first position in response to a cessation of the first pressure. The second sleeve can be positioned adjacent to the first sleeve to define a swell chamber. The swell chamber can actuate a downhole tool by a pressure stored in the swell chamber by the expansion of the first sleeve.

摘要： Wellbore systems containing a hydraulically regulated primary safety valve may have their hydraulic regulation transferred to an insert safety valve disposed in a nipple. Transfer of the hydraulic regulation may take place mechanically, such as through axial displacement of a sliding sleeve or by replacement of a hydraulic spool. Wellbore systems configured for axial displacement of a switching mechanism may comprise: a tubing string comprising a nipple and a primary safety valve, the primary safety valve being disposed in the tubing string above or below the nipple; a control line and a balance line in hydraulic communication with the primary safety valve and in latent hydraulic communication with an internal flow pathway within the nipple; and a switching mechanism that is axially displaceable to establish hydraulic communication between an insert safety valve positioned in a bore of the nipple and both the control line and the balance line.
