摘要： A method for improving sealing in boreholes includes temperature controlling seals to maintain sealing loading by managing temperature of the seal to a target temperature range. A borehole system includes a borehole in a subsurface formation, a string in the borehole, a seal tool in contact with the string and temperature controller within or in thermal proximity to the seal.

摘要： A seal includes a seal body and a temperature controller in thermal communication with the seal material. A method for controlling temperature of a seal including applying an energy source to the temperature controller, and generating a temperature difference in the temperature controller. A borehole system including a borehole in a subsurface formation, a string in the borehole, and a seal tool disposed within or as part of the string.

摘要： A backup comprising a gage ring having frustoconical surface and a groove in the frustoconical surface. The backup further includes a segment having a nose engaged with the groove, the segment having an element portion with an overlap finger and a finger receptor and a gage portion with an overlap finger and a finger receptor. A wedge ring is in contact with the segment and a retainer member is disposed to retain the segment. A method for using the backup and a system are included.

摘要： A seal including a seal material and a temperature control material in thermal communication with the seal material. A method for producing a seal having temperature regulating properties including adding a dopant to a seal material in a quantity that supports electrical conductivity and disposing an electrical connector on the seal. A borehole system comprising a borehole in a subsurface formation, a string in the borehole, and a seal tool disposed within or as a part of the string.
