Publication number: 20140175750Abstract: A seal assembly capable of low temperature service is disclosed. It features upper and lower metallic backup rings that are specially shaped to act as a spring to keep the sidewalls of such rings in contact with the inside and outside surfaces to be sealed to prevent extrusion of the seal material even in low temperature situations. Inner and outer grooves are provided. O-ring seals, used for the ID of the seal, are manufactured to have a slightly greater diameter than the groove into which they will be installed. The greater length provides stored energy to promote sealing functionality in cold temperature situations. The O-rings used for the OD of the seal are manufactured to have a slightly smaller diameter than the groove into which they will be installed. The shorter length provides stored energy to promote sealing functionality in cold temperature situations.Type: ApplicationFiled: December 17, 2013Publication date: June 26, 2014Inventors: Kendall E. Keene, John C. Vicic

Publication number: 20030209861Abstract: Accordingly, there is provided herein a metal end cap seal assembly for sealing the annulus between two tubular members that has improved sealing abilities at a wide range of temperatures. The metal end cap seal generally comprises a resilient ring with a metal end caps on either end. The inner diameter of the resilient ring has one or more circumferential cavities open to the inner diameter and connected to the outer diameter by one or more radial holes. After the seal is energized, a high pressure is applied to the seal so that the pressure will migrate past the nose of the seal, through the radial holes, and into the groove. The groove is shaped so that, once the high pressure is relieved, the pressure within the groove will become trapped. This trapped pressure acts as a source of stored energy within the seal and causes the seal to be energized to a level that is greater than the energization capable without the trapped pressure.Type: ApplicationFiled: May 10, 2002Publication date: November 13, 2003Applicant: Cooper Cameron CorporationInventors: Kendall E.

Publication number: 20030209857Abstract: The present invention relates to a metal end cap seal for a well sealing assembly for sealing the annulus between two tubular members that has improved sealing abilities at an increased range of temperatures. The metal end cap seal generally comprises a resilient ring with a metal end caps on either end. The inner diameter of the resilient ring has one or more grooves that enable the installation of a one or more o-rings. The o-rings are sized so as to provide an increased stored energy within the resilient ring so that the sealing engagement is increased.Type: ApplicationFiled: May 10, 2002Publication date: November 13, 2003Applicant: Cooper Cameron CorporationInventor: Kendall E.

Publication number: 20030209862Abstract: The present invention relates to a metal end cap seal for a well sealing assembly for sealing the annulus between two tubular members that has improved sealing abilities at an increased range of temperatures. The metal end cap seal generally comprises a resilient ring with a metal end caps on either end. The inner diameter of the resilient ring has one or more annular protrusions along the inside diameter of the resilient ring. The annular protrusions are sized so as to provide additional interference with the internal tubular member and provide areas of localized compressive stress within the resilient ring while maintaining a desirable overall stress distribution.Type: ApplicationFiled: May 10, 2002Publication date: November 13, 2003Applicant: Cooper Cameron CorporationInventors: Kendall E.
