Seal assembly
A seal assembly, for setting at a predetermined depth in a conduit penetrating subterranean formations, consists of an elongate mandrel; an elongate tubular surface; an expansible tubular seal element; supporting and compression means for compressing the seal; slips; collect latch for releasably maintaining a set position; interconnection and release means for releasably connecting with a setting tool; and connection means for connecting with a terminal device. It has the following features: (1) a bypass means for bypassing fluid when the seal element is not set and blocking flow of fluid once the seal element has been set; (2) a balancing chamber and piston for reducing the force the collect latch is required to sustain; and (3) a safety means for preventing unsetting of the retainer means as long as the differential pressure across the seal is too great.
