Class Information
Number: 166/100
Name: Wells > Lateral probe or port sealed against well wall
Description: Devices comprising (1) a means pressed against the side wall of a prepositioned well conduit so as to form a seal around a port for passage of fluid or (2) a means penetrating the earthen side wall of the well bore so as to provide a passage for fluid between a tubular member in the well and the formation.
