Abstract

See full text

A core barrel restraint adapted to prevent inadvertent dropping of a core barrel assembly during retrieval of a core sample can include a cup adapted to fit over an overshot and a brace adapted to be coupled to a core barrel assembly. A cable can connect the cup and brace and prevent the core barrel from falling if the overshot latch mechanism holding the core barrel assembly and overshot together fails.
