Denver-based Sentinel Peak Resources LLC said it has not applied for exemptions to California’s underground injection control regulations as stated in California’s UIC Well Exemptions Challenged in Federal Court. Previous leasehold owner Freeport McMoRan Inc. requested exemptions in 2015, and they were granted in April. However, Sentinel said it has no plans to follow through with the project. In addition, Sentinel said it injects its wastewater and fluids into the same reservoir being produced and not into nearby aquifers. NGI’s Shale Daily regrets the errors.
