Abstract
This paper presents a synergistic interpretation of drilling logs, formation logs, production logs and pump test data from a low temperature geothermal well to yield the stratigographic sequence and the nature and thickness of the permeable zones. The well penetrated fluvial and lake bed sediments (ash/sand/clay) with occasional basalt/andesite. An unconventional application of repeat temperature logging in a nearby well during the drilling of the subject well proved invaluable in locating permeable zones and in casing and completion.
