Abstract: An access device installs on a wellscreen joint during manufacture and allows access to one or more spaces or layers where tracer elements can be installed adjacent the joint's screen jacket (i.e., internal and/or external to the screen jacket). Portion of the access device is removable to allow installation of the tracer elements after the joint has been manufactured. With the tracer elements installed, the access device can be reassembled and locked in place. Any various mechanism can allow the access device to be partially removed, the tracer elements to be installed, and the access device to be reassembled in place. For example, an end ring holding the jacket on the basepipe can have at least one channel communicating with a space or layer for insertion of the tracer elements. A removable cover can be removed to allow access to the at least one channel and can be reattached for the wellscreen to be used downhole.
