The repair work was completed by US 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, the company said.
After the squeeze job 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, the company added.
