Abstract
A latch for interconnecting a first wellbore element and a second wellbore element in a manner such that the first and second elements can be conveyed into a wellbore in tandem and then disconnected from one another includes a first latch head connectable to the first element, a second latch head connectable to the second element, and a lock mechanism connectable between the first and second latch heads, wherein the lock mechanism structurally degrades when exposed to the wellbore environment allowing disconnection of the first latch head and the second latch head.
