dc.description The initial four holes were drilled in 1961 by the Hawaii Thermal Power Company. Recent measurements have shown that these temperatures have not change significantly. It is interesting to note that TTW #2 shows virtually a continuous increase in temperature with depth, with a sharp gradient from 253 to 262 feet. However, the well had caved in at around 361 feet, when a temperature of 97° was measured at this point in 1975. TTW #3 was measured to the bottom of the well. where a peak temperature of 93°C was measured at around 540 feet. A sharp positive gradient was measured from 460 feet to 540 feet, and a rather sharp negative gradient (not as steep as the positive gradient) from 540 feet to the bottom (Epp and Ha1unen, 1976).
dc.description.abstract The history of geothermal well drilling in Hawaii is reviewed briefly. The following are discussed: the geophysical program, pre-drilling speculative models, geothermal reservoir engineering, the drilling program, the measurement activities, a preliminary reservoir analysis of HGP-A well, and future activities.
