Abstract (en)

[origin: WO0198626A1] A system is provided for creating at least one conduit in a borehole formed in an earth formation. The system comprises a device which includes movement means for moving the device in longitudinal direction through the borehole, and injection means for injecting a hardenable substance into the borehole so as to form, for each said conduit, a layer of hardened substance in the borehole behind the device, said layer defining the conduit. The system further comprises control means for controlling the rate of injection of said substance by the injection means so as to correspond with the rate of movement of the device through the borehole by the movement means.
