A method and system for determining information about a wellbore with coiled tubing. A downhole device may be positioned within coiled tubing and run down the wellbore to determine diagnostic information about a location with the wellbore. The downhole device may store diagnostic information in a storage device that may be analyzed when the device is returned to the surface. A downhole device may be connected to the end of a string of coiled tubing that includes a diagnostic device and memory sealed in a chamber. A flow path past the chamber is in communication with the coiled tubing string permitting the flow of fluid past the chamber. A downhole device including a diagnostic device may be connected to a recess in an exterior of a coiled tubing string.

An acoustic telemetry method for use with a subterranean well can include positioning a well tool in the well, the well tool including an acoustic transmitter and a sensor, and an acoustic receiver in the well receiving an acoustic signal transmitted by the transmitter, the acoustic signal including information representative of a measurement by the sensor. A system for use with a subterranean well can include a well tool positioned in the well, the well tool including an acoustic transmitter and a sensor, the acoustic transmitter transmits an acoustic signal including information representative of a measurement by the sensor to an acoustic receiver positioned in the well.

A wellbore tool string includes a combination of acoustic inspection tool(s) and electro-mechanical inspection tool(s). The tool string is configured to combine acoustic with electro-mechanic wellbore inspection to circumvent limitations that both technologies may be subject to in wellbore environments. Anomalous data from one or more acoustic tools can be correlated with data acquired by an electro-mechanical tool incorporated into the same tool string to determine wellbore conditions that may have adversely affected the operation of the acoustic tool(s).

A communication system, comprises a composite slickline including an electrical conductor surrounded by an electrically insulating structural material, a downhole tool; and a sensing element. The composite slickline is mechanically and electrically coupled to the downhole tool and extends from the downhole tool to the sensing element. The composite slickline and the sensing element are capacitively coupled so as to permit relative movement therebetween and so as to permit an electric field to extend from the electrical conductor of the composite slickline to the sensing element through the electrically insulating structural material of the composite slickline for the transmission of an electrical and/or an electromagnetic signal between the downhole tool and the sensing element via the composite slickline.
