Abstract
A locking mechanism for securing a jumper tube to a shunt tube in a well screen assembly for use in gravel packing features a jumper tube having a telescoping connector that extends to engage the shunt tube and a locking mechanism that extends the connector the proper distance and then locks the connector into place by engaging lugs that are connected to the jumper tube. An apparatus and method for securing a connector tube to a well screen assembly features a receiver that is attached to the well screen assembly and is configured to receive a connector tube and secure the connector tube into place with screws. The receiver can be mounted to the well screen assembly via the shunt tube, a top/middle-bottom ring assembly, directly to the base pipe.
