This file contains temperature (deg C) versus depth (m). The letter B refers to the Bnd (2nd) log that was run in this hole. Each well was logged several times to monitor temperature changes after the well was drilled in order to establish when thermal equilibrium was reached. This table can be downloaded in the usual way using the File options in your Web browser.
