摘要： Embodiments of the present invention provide systems and methods for' lining a wellbore. In certain aspects, the systems and methods comprise providing a fluid composition that is solidifiable or gellable on exposure to actinic radiation of a predetermined wavelength at the wall of open-hole wellbore and providing actinic radiation at the predetermined wavelength to solidify or gel the composition.

摘要： A fluid used in a borehole containing suspended solid objects made by an additive manufacturing process. An additive process of solidifying a liquid composition at a succession of selected locations within a workspace, in accordance with a digital design allows a wide variety of shapes to be made. The fluid may be a drilling fluid or a borehole treatment fluid used prior to cementing and the objects may act, possibly in conjunction with other solids, to block loss of fluid into fractures in the formation around the borehole.

摘要： A method of lining tubing within a wellbore comprises applying a polymerisable fluid composition containing a photoinitiator to the interior surface of that tubing and initiating polymerisation of the composition by exposing it to actinic radiation, suitably light or ultraviolet with wavelength 250 to 800 nm. The composition is preferably stable against heat but polymerises quickly when exposed to the actinic radiation. The composition may be spread onto the tubing and exposed to actinic radiation as soon as it has been spread into a layer, suitably with a tool which skims the tubing surface with applicator pads for dispensing and spreading the composition, immediately followed by exposing the spread composition to actinic radiation. A second option is that the composition is provided as a sleeve which is expanded against the tubing, exposure to actinic radiation preferably then being achieved by means of light guides or light emitting diodes within the sleeve.
