    Abstract: A plug releaser includes, a first tubular with at least one first port through a wall thereof, at least two plugs sealingly engaged with the first tubular defining a first chamber between the first tubular and the at least two plugs. The at least two plugs are rupturable or releasable from the first tubular at selected pressure differentials thereacross, and a second tubular is in operable communication with the first tubular at locations beyond the at least two plugs. The at least one first port provides fluidic communication between the first chamber and an outside of both the first tubular and the second tubular and the at least one first port is sized to prevent pressure differential across the at least two plugs from building to a selected pressure differential needed to rupture or release the plugs in either direction for at least a period of time.
