ABSTRACT The preliminary evaluation of the first direct‐use (low enthalpy) geothermal well in the United Kingdom included core analysis, geophysical logging, and drill‐stem testing. The effective aquifer is restricted to a few relatively thin loosely cemented bands in the Triassic sandstones at a depth of approximately 1660 m. With an aquifer temperature of at least 67°C the initial assessment of transmissivity, 18 m2/day, suggested that a thermal yield of approximately 2.5 MW would be obtainable. The results are in reasonable agreement with those of a subsequent long‐term production test.
