A fiber optic approach for cement placement and hydration assessment of deep geothermal boreholes

A fiber optic approach for cement placement and hydration assessment of deep geothermal boreholes

Abstract Achieving well integrity is mandatory for a geothermal well’s safe and sustainable operation. One of the most critical steps is the success of the primary cementing. Conventional monitoring only shows discrete snapshots after completion of the cement job. However, optical fiber sensors enab...
