Abstract
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.

A method of determining information about the production from a zone of a wellbore comprising:
- determining diagnostic information concerning a first zone of a wellbore with a downhole device positioned adjacent to the first zone of the wellbore, the downhole device comprising an electronic device positioned inside of a housing connected to a recess in an exterior of coiled tubing;
- and
- storing the determined diagnostic information of the first zone in a memory device.
A system to monitor a zone of a wellbore comprising:
- a string of coiled tubing;
- a housing having a first end and a second end, the housing being closed at the first end and being closed at the second end, at least one of the first end and second end being selectively closed to permit access into the housing;
- an electronic device positioned within the housing, the electronic device configured to obtain diagnostic information of a wellbore;
- and
- the housing being connected to a recess in a portion of an exterior of the string of coiled tubing with a flow path in an interior of the string of coiled tubing past the recess.
