This paper summarises the work undertaken and results obtained during the period late-1983 to early-1986 at the geothermal HDR research facility run by the Camborne School of Mines (CSM) at Rosemanowes Quarry in Cornwall, UK. This period corresponds to Phase 2B of the project, during which a third well was drilled to a depth of about 2500 m in order to investigate further the reservoir created from the two 2000 m wells drilled in Phase 2A. Important results from this work include the recognition of shear movement as a consequence of hydraulic stimulation and the development of viscous stimulation as a means of overcoming the resulting problems. The different geophysical and geochemical techniques are described, as are the initial stages of long-term circulation.
