Temperatures recorded in Hole 1188F during wireline logging operations and with the UHT-MSM temperature probe several days later. Temperatures measured during wireline operations show the immediate postdrilling disturbance of the temperature gradient with a maximum recorded at 99.6ºC. Measurements with the UHT-MSM four and seven days later show the changes in the temperature field while equilibrating. The maximum-recorded temperature was 313ºC.
