ABSTRACT:
A method of deploying a well screen and associated apparatus provide convenient and economical completion operations within subterranean wells. In a disclosed embodiment, a method of positioning a screen includes attaching the screen to a completion string before stimulation operations are performed on a formation. Initially, the screen is spaced apart from the formation. After the stimulation operations are performed, the screen is positioned opposite the formation and packers are set above and below the screen. In order to thus position the screen, a work string is inserted into the completion string, the screen is attached to the work string, and the screen is released from the completion string. After the packers are set, the work string may be retrieved and the formation placed in production. The screen and packers prevent flow of particulate material from the formation into the completion string. Other methods are provided as well.
