System, apparatus, and method of telemetering downhole sensor information to the surface while operations are performed in an oil or gas well using coiled tubing. Data are transmitted on coiled tubing as digital signals encoded in acoustic signals. In one implementation, a stripper packer through which coiled tubing is moved into a well is operated between at least a first state and a second state; and an acoustic communication device responds to operation of the stripper packer such that when the stripper packer is in the first state, the acoustic communication device is decoupled from acoustic communication with the coiled tubing, but when the stripper packer is in the second state, the acoustic communication device is coupled for acoustic communication with the coiled tubing.
An acoustic communication device for coiled tubing, the acoustic communication device comprising:
An acoustic communication device for a coiled tubing system including a stripper packer having a hydraulic actuator, the acoustic communication device comprising an accelerometer adapted to move selectably between contact and non-contact positions relative to coiled tubing moved into a well through the stripper packer, wherein movement of the accelerometer relative to the coiled tubing is responsive to the hydraulic actuator operating the stripper packer.
A system for acoustic communication along coiled tubing operatively associated with a wellhead assembly, the system comprising:
A method of providing for acoustic communication at a wellhead, comprising the steps of:
A coiled tubing telemetry method comprising the step of transmitting data on a coiled tubing string as acoustic signals.
A coiled tubing telemetry method comprising the steps of:
A coiled tubing telemetry system comprising:
