Temperatures and heat flow in INEL-GT1 and WO-2 boreholes, Snake River Plain, Idaho

The researchers have logged temperatures in the deep geothermal test at the INEL test site on the eastern Snake River Plains in Idaho (INEL-GT1) three times over a period of 8 years. The first logging was on 8/20/82 when they reached a depth of 2100 m. They were unable to get past the casing shoe at that depth. In 1983 (7/25/83) they relogged the well with a centralizer on the temperature tool and got past the casing hanger to the end of their cable at 2870 m. In both cases the logs were made at a 0.5 m recording interval. In 1990 the researchers relogged the well for a third time and for the first time reached the bottom of the well at 3130 m. In this log the temperatures were measured at 0.2 m intervals. The temperature-depth plots for the last two logs are compared and the gradient logs for the three logs are compared. The differences in temperature are almost too small to see on the plot. The only significant differences are in the depth interval 700 to 1850 m, a section of the hole with a number of fluid disturbances.
