High Temperature Geothermal Elastomer Compund Development

PDF Version Also Available for Download.

Description

Reliable casting packer seal elastomers for the unusually severe geothermal environment at 260 C (500 F) did not exist in 1976. L'Garde, Inc., was awarded a contract to fulfill this need by the US Department of Energy. Successful development was completed in 1979. Compounds based on four different polymer systems were developed, all of which exceed the contract requirements. Successful laboratory tests above 300 C (575 F) have been performed with packer seals. Field tests to temperatures as high as 317 C (603 F) have been performed on static O-rings in a cablehead. Successful, dynamic, drill bit seal tests were ... continued below

Field tests to temperatures as high as 317 C (603 F) have been performed on static O-rings in a cablehead. Successful, dynamic, drill bit seal tests were run with a presoak temperature of 288 C (550 F). The successful compounds are based on the following polymer systems: EPDM; FKM; EPDM/FKM blend, and propylene-TFE.
