Study of the Potential for an Off-Bottom Dynamic Kill of a Gas Well Having an Underground Blowout

Abstract

Summary This paper reports on an analysis that links expected reservoir performance with wellbore hydraulics. The dynamics of counterflow of the kill fluid and gas below the kill string can play a significant role in the expected behavior during a dynamic kill. The design concepts and techniques presented should be applicable to any well that requires the kill string to be run or snubbed into the well or one in which the string is a significant distance off bottom at the time of a blowout and cannot be lowered to bottom.
