Abstract
Methods and apparatuses for preventing the uncontrolled release of fluid materials from a well string during decoupling are provided. The apparatus includes an elongated body having an internal passage running along the longitudinal axis thereof, wherein the internal passage is configured to conform to the outer perimeter of a portion of a pipe and coupling of a well string such that fluid released from the coupled pipes during a decoupling operation is controllably redirected downward.
