U.S. Geothermal Inc. reports it has successfully completed the repair of production well RRG-7 at the Raft River geothermal power project in southeast Idaho, sealing off a leak that was cooling geothermal fluid.

In an announcement today, U.S. Geothermal Inc. reports that it has successfully completed the repair of production well RRG-7 at the Raft River geothermal power project in southeast Idaho. The repair work was completed by U.S. Geothermal Services Inc., a wholly owned subsidiary, according to plan and budget. Previously well RRG-7 experienced a leak between two overlapping casing strings that allowed cooler geothermal fluid to flow into the well. The repair involved removing the production pump and then completing a “squeeze” job whereby grout was injected into the leaking lap joint.

After the squeeze job successfully sealed off the leak, the overhauled production pump was installed and production well RRG-7 was placed back into service on July 2nd. The well is currently producing 1,300 gallons per minute of 297 degrees F fluid. The repair program also includes restoring production at well RRG-2 and those repairs are underway and ongoing.”
