Exploration Basis
To determine effectiveness of FIS for geothermal exploration
In order to test FIS for geothermal exploration, drill chips were analyzed from Coso well 83-16, which were selected at 1000 ft intervals by Joseph Moore. Sequential crushes done by our CFS (crushfast-scan) method (Norman 1996) show that chips have a high density of homogeneous fluid inclusions. Analyses were averaged and plotted verses depth, and interpreted. Fluid inclusion gas analyses done on vein minerals from drill hole 68-6 that were analyzed earlier (Adams 2000) were plotted for comparison in order to confirm that similar analyses are obtained from chips and vein minerals. It is apparent that fluid inclusion analysis detects a change in gas K466 chemistry at about 5500 ft, which is the top of the Coso production zone.
