Abstract
A well screen cover including a channel running along substantially the entire length of the well screen cover. The channel may be formed directly into the cover or separately formed and welded to the cover. The channel is open to the exterior of the well screen cover and is formed to house a cable, such as a fiber optic cable, which is run into a well bore along with the well screen.
Claims16
A well screen cover, comprising:
- an elongated tube coupled to and surrounding an elongated well screen;
- and
- an elongated channel formed in the tube and running substantially the length of the tube.
A well screen cover, comprising:
- an elongated tube coupled to and surrounding an elongated filter medium, the tube having an outer surface;
- and
- an elongated channel coupled to the tube and running substantially the length of the tube, the channel being open to the outer surface of the tube.
A method of manufacturing a well screen cover, comprising the steps of:
- spirally winding a strip of metal to form an elongated cylindrical tube;
- and
- pressing an elongated metal bar into the wall of the tube, the metal bar being positioned along the length of the tube, substantially parallel to a longitudinal axis of the tube, to form an elongated channel in the tube, which runs substantially the length of the tube.
A method of manufacturing a well screen cover, comprising the steps of:
- providing an elongated tube having a wall that includes an inner surface and an outer surface;
- providing an elongated channel having two sidewalls;
- coupling the sidewalls of the channel to the inner surface of the wall of the tube;
- and
- removing a portion of the wall between the two sidewalls.
A method of manufacturing a well screen cover, comprising the steps of:
- providing an elongated tube having first and second tube ends and a wall that includes an inner surface and an outer surface, the tube defining a longitudinal axis;
- removing a portion of the wall of the tube to create a slot running substantially parallel to the longitudinal axis, the slot having first and second slot ends, the first slot end spaced-apart from the first tube end and the second slot end spaced-apart from the second tube end;
- and
- coupling an elongated channel to the inner surface of the tube, below the slot.
A method of manufacturing a well screen cover, comprising the steps of:
- providing an elongated tube having a wall that includes an inner surface and an outer surface, the tube defining a longitudinal axis;
- slitting the wall of the tube along the tube length, substantially parallel to the longitudinal axis;
- prying the wall of the tube apart to widen the slit;
- and
- inserting a plurality of rings coupled to a channel into the tube, the rings lying adjacent to the inner surface of the tube, the channel positioned within the widened slit.
