Abstract
A method of encasing a wellbore is provided comprising the application of 3D printing technology to apply a series of layers of lining material to the interior surface of a wellbore. The layers may be of different materials to make best use of their different material properties, to provide structural integrity and good sealing properties, for example. Through suitable printhead control, specific structural features such as channels for receiving measurement, power or communications equipment may be incorporated into the lining structure. Associated devices for depositing the layers of lining material are also provided.

A method of lining a wellbore comprising the steps of:
- inserting a directional nozzle into the wellbore;
- and
- controlling the direction of the nozzle and controlling flow through the nozzle to deposit at least one layer of lining material onto the interior surface of the wellbore.
A device for depositing at least one layer of material onto an interior surface of a wellbore, comprising:
- a directional nozzle;
- a source of material in connection with the nozzle;
- means to control the direction of the nozzle;
- and
- means to control the passage of the material through the nozzle, whereby to deposit at least one layer of lining material onto the interior surface of the wellbore.
