摘要： Systems and methods for use in wellbore completion and/or for operating a downhole tool, such as a downhole tool associated with well fracturing, include a tool assembly having a lower packer, an upper packer, a first downhole tool in the form of a flow control device, a second downhole tool in the form of a fracture tool, a plurality of production tools and a plurality of screens. Each tool assembly includes or is associated with a downhole actuator in the form of a shifting tool which is operable to actuate one or more of the first downhole tool, second downhole tool or production tools in use. The actuator may be disposed on, or operatively associated with a string, such as a tubular string. All operations are performed with a body of the shifting tool in tension.

摘要： A method for completing a wellbore (1) comprises operating a) a tool (15) to alternatively open and close a throughbore (40) of the completion (4); b) a tool (13) to alternatively open and close an annulus (5) defined between the outer surface of the completion and the inner surface of the wellbore; c) a tool (11) to alternatively provide and prevent a fluid circulation route from the throughbore of the completion to the said annulus; and d) at least one signal receiver and processing tool (9) capable of decoding signals received relating to the operation of tools a) to c). The method entails running the apparatus is run into the well bore, and tool a) is operated to close the throughbore; the pressure within the fluid in the tubing is increased to pressure test the completion; tool b) is operated to close the annulus; tool c) is operated to provide a fluid circulation route from the throughbore to the annulus and circulate fluid through the production tubing and out into the annulus and back to surface; tool c) is then operated to prevent the fluid circulation route from the throughbore to the annulus such that fluid is prevented from circulating; and tool a) is operated to open the throughbore.

摘要： The switching device comprises an electronic switch (111) embedded within a downhole tool (100) and an activator (20) for remote switching of the electronic switch (111). Theactivator (20) may be a handheld unit that is used at the surface of the wellbore by an operator or may be a wireline run unit. The activator (20) permits wireless and contactless activation of the electronic switch (111) without the need for mechanical switches which could provide a point of failure for the downhole tool (100). The electronic switch (111) comprises an electronics module and a power source such as one or more batteries (126) wherein in the active configuration, the switch (111) can allowelectrical connection between the electronics module and the power source (126) and in the inactive configuration, the switch (111) prevents electrical connection between the electronics module and the power source (126).
