Proppant Injection in HQ Boreholes

Battelle Memorial Institute (Battelle), Pacific Northwest Division in operation of the Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy (DOE) is requesting information from potential suppliers regarding their capabilities to develop, design, and implement an approach for injecting proppant into hydraulic fractures within the CUSSP testbed, located on the 4100 ft level of the Sanford Underground Research Facility. A flowing fracture system between injection and production wells was generated during the EGS Collab Experiment 3.
