Abstract: The invention is a petroleum well tracer injection and monitoring method comprising the steps of providing a one or more curable liquid doped with one or more tracer, arranging said one or more liquid in an intervention liquid injecting tool, running the injection tool into a production tubing in a petroleum well to one or more desired injection position along the tubing, actuating the injection tool to apply one or more portions of the tracer doped liquid at said one or more desired positions, each said portion deposited to form a material deposition at a tubing wall of said tubing, allowing the well to produce and monitoring the tracers in the production flow and a tool to perform the injection.

Abstract: A method of supporting a tubular within a bore including the steps of at least partially expanding a sleeve into contact with a bore wall to secure the sleeve within the bore, and engaging a portion of the tubular to be supported with the sleeve to provide hanging support for the tubular. In one embodiment, the sleeve is expanded by engagement with the tubular. In another embodiment, the sleeve is initially expanded using a roller expansion tool, with further expansion being achieved by way of engagement of the tubular with the sleeve. An apparatus for supporting a tubular within a bore in one embodiment comprises an expandable sleeve having a first surface and being adapted to be expanded into contact with a bore wall, and a conical portion adapted to be coupled to a tubular, the conical portion having a second surface adapted to engage the first surface of the sleeve.
