摘要:
A telemetry system and method of downhole communication is disclosed. A first electromagnetic signal propagates through a first annular region between a work string and a wellbore wall and is received at an electromagnetic receiver of a repeater. A second electromagnetic signal related to the received first electromagnetic signal is created at a processing unit coupled to the electromagnetic receiver. The second electromagnetic signal is transmitted from a transmitter of the repeater into a second annular region between the work string and the wellbore wall. The repeater may be detachably coupled to the work string and may facilitate communication between a first communication device at one of an uphole location and a downhole location and a second communication device at another of the uphole location and the downhole location.

A tool setting arrangement includes a mandrel, and a tool positionable at the mandrel. The tool includes, a cone, and at least one slip in operable communication with the cone configured to radially expand to set the tool when the slip is moved relative to the cone with at least a setting load. The at least one slip has a portion configured to engage with a feature of the mandrel such that movement of the mandrel relative to the cone causes the at least one slip to move relative to the cone, at least one of the portion and the feature is configured to release at a release load to disengage the mandrel from the tool. The release load is selected to be greater than the setting load.
摘要:
A wellbore system is disclosed. The wellbore system includes a coil in the wellbore, a magnetic element conveyed from a surface location that is configured to oscillate or rotate in an opening in the coil to generate electrical energy, and a device in the wellbore that utilizes the generated electrical energy.
摘要:
A sensing indicator for a downhole tool, the sensing indicator includes a sensing mechanism including a sensing device and an RFID tag. Wherein the RFID tag is only readable when a set limit is exceeded. The set limit related to a sensed condition of a downhole component of the downhole tool; and, a housing supporting the sensing mechanism. The housing protecting the sensing mechanism from downhole conditions. Further is method of indicating whether a sensed condition of a downhole component in a downhole tool has exceeded a set limit
