Apparatus for treating a wellbore screen and method

An apparatus for treating a wellbore screen with a coating material, the apparatus comprising:

• a support for the wellbore screen, the support supporting an outer surface of the wellbore screen and presenting the wellbore screen with open access to its inner bore, as defined by an inner tubular wall of the wellbore screen;
• an elongate injector for injecting coating material into the inner bore of the wellbore screen, the elongate injector including a supported end, a distal end including an injector head having a port formed therein and a coating material delivery line extending through the elongate injector from a coating material supply to the port at the distal end;
• a spreader ring configured for urging against the inner tubular wall, for spreading the coating material introduced from the port onto the inner tubular wall and into a screening component of the wellbore screen;
• a heating element on the distal end of the elongate injector for heating the coating material passing through the coating material delivery line;
• and a driver for positioning the elongate injector into the inner bore and moving the elongate injector through the inner bore to introduce the coating material to the inner bore such that the coating material can be distributed onto the inner tubular wall of the wellbore screen.
