Abstract
A head member having a piston provided thereon is connected to an elongate tube such as a micro-tube. The micro-tube contains one or more optical fibres, preferably suspended therein by a protective fluid such as a scavenging gel. The head member is preferably inserted into an already-deployed downhole tubular and fluid is pumped down that already deployed tubular behind the piston such that the head member and attached micro-tube and optical fiber(s) are pumped downhole. A sealing means such as a resin material may be pumped downhole in the annulus between the outer circumference of the micro-tube and the inner circumference of the already-deployed tubular downhole in low viscosity form and which may be adapted to cure or harden after a passage of time and/or under application of heat.
