Title: Pressure energized/pressure intensified casing seal
Inventor: ZOLLO DAVID A
IPC: E21B33/00
Filed: 1988-08-29
Granted: 1991-06-25
Abstract: ABSTRACT OF THE DISCLOSURE        A casing seal for use with  a  source  of  high pressure    fluids   with   apparatus   for   preventing shredding  of  the  seal  with   variations   in   fluid pressure.   A  T-shaped annular  metal  ring provides a multiplication of fluid  pressure  so  pressure  exerted on  an  elastomeric  sealing  ring  is  greater than the fluid  pressure.   This  multiplication  prevents  gases from entering the elastomer and  prevents  shredding  of the   elastomer   when   pressure   is   released.   The multiplication of pressure  also  forces  the  elastomer firmly  against  a casing and a casing head to provide a fluid-tight seal.
