Abstract:
A tubular assembly includes a tubular having at least one opening. A slidable sleeve is slidingly mounted relative to the tubular. The slidable sleeve is shiftable between a first position, and a second position. A biasing member selectively biases the slidable sleeve in one of the first position and the second position. A degradable locking member is mounted relative to one of the tubular and the slidable sleeve. The degradable locking member selectively retains the slidable sleeve in the other of the first position and the second position. The degradable locking member is configured to degrade when exposed to a downhole fluid allowing the biasing member to shift the slidable sleeve back to the one of the first position and the second position.
