Camborne geothermal energy project techniques for the improvement of the hydraulic performance of HDR reservoirs

Abstract

An experiment to place proppants from the production well at Rosemanowes is described, and it is concluded that the proppant was placed satisfactorily, and resulted in an improved hydraulic performance in a downhole pump test. This was achieved at the expense of the thermal performance of the system as a new cold main flow entry to the production well was introduced. A localised secondary stimulation in the production well failed to improve the hydraulic performance of the low flow zone in that well. The proppant placement accompanying this stimulation failed because the gel carrying the proppant did not cross-link. A repeat secondary stimulation in the production well was carried out satisfactorily, but again failed to improve the hydraulic performance of the low flow zone significantly. This result led to proposals for a ``multi-cell`` stimulation design for HDR systems, based on many small independent stimulations placed to connect the production and injection wells in a parallel configuration.
