摘要： Setting mechanisms for downhole tools are described that take advantage of hydrostatic pressure in the wellbore which is harnessed to set a tool after exposure to well fluids for a given time or temperature defeats a lock and allows hydrostatic forces to trigger the setting of the tool. Alternatively, some other biasing source is released to set the downhole tool after exposure to well fluids for a time or a temperature and time defeats a lock and allows the biasing source to set the tool. While applications to packers are preferred, other downhole tools can be set in his manner removing the need for an inner string, dropping a ball on a seat or pressurizing the wellbore to achieve the setting of the downhole tool.

摘要： A packer assembly which incorporates a swellable elastomeric packer element and one or more swellable thermoplastic components. The swellable thermoplastic components are support rings that are located at each axial end of the elastomeric element and provide positive mechanical backups for the elastomeric element to limit extrusion of the packer element.

摘要： A setting mechanism is made to respond to hydrostatic pressure. Upon reaching a predetermined depth corresponding to a given pressure, a pilot piston is shifted to allow well fluids to bypass a first set of piston seals and reach a second set. A shear pin that held the pilot piston in position is broken as the hydrostatic pressure increases with greater depth attained. However, the shifting of the pilot piston does not cause the main piston in the assembly to set the downhole tool. The action of the well fluids on the secondary seal set on the pilot piston eventually fail the second seal set allowing hydrostatic pressure to bypass them and actuate the main piston that will set the downhole tool. Raising the tool from the wellbore allows the spring acting on the pilot piston to seal in a bore to isolate hydrostatic pressure from the operating piston.

摘要： In one embodiment telescoping members are extended to bridge an annular gap either before or after it is cemented. Some of the telescoping members have screens and others have flow passages that can be selectively opened with associated valves to frac an interval in any order desired. The valves are then closed after the frac job and the other telescoping members are made to allow screened flow from the fractured formation. In another embodiment an interval to be gravel packed and fractured has a series of screens and selectively opened valves on a bottom hole assembly such as a liner. One or more external packers are provided. The entire interval is gravel packed at one time followed by packer actuation and then selective opening of ports to conduct a fracture operation in any of the zones defined by the set packers and in any desired order.

摘要： A multilateral reference point sleeve includes a tubular member configured to be received in a tubing string of a wellbore. The tubular member has an uphole end and a downhole end. The uphole end is angled to define an orientation profile, and the orientation profile has an orientation slot extending therefrom. A method for orienting a tool in a wellbore includes running the multilateral reference point sleeve into the casing in the wellbore, anchoring the sleeve to an inner surface of the casing, running the tool into the tubing string, causing a pin on the tool to engage the orientation profile on the sleeve, and causing the pin on the tool to engage the orientation slot on the orientation profile.

摘要： A shifting tool is disclosed which allows movement of a shifting sleeve, to be followed by an additional force applied to ensure complete stroking of the shifting sleeve. This is accomplished by a shifting key to normally shift the shifting sleeve, followed by an overpull key which engages while the shifting key is still engaged. Once a predetermined force has been applied to the overpull key, the force applied from the surface is removed so that the tool may disengage from the sleeve. Subsequent manipulation, without necessarily any removal from the wellbore, if it does not result in a reengagement, provides feedback that the shifting sleeve has, in fact, shifted its full stroke. An emergency release is available which actuated by an overpull force beyond a predetermined level, applied while the overpull key is engaged for an emergency release from the shifting sleeve.
