Fig. 11 shows geothermal well costs (in black) as compared to hydrocarbon well costs (in red) represented by the average 2009 JAS oil and gas drilling costs (full red markers) and a set of records for individual ultra-deep oil and gas wells (blank red markers).t determines average drilling costs based on 40â60% of wells drilled each year (Kaiser, 2007). Wells are broken down based on geographic location (onshore, offshore), state, well class (oil, gas, dry) and type (exploratory, development).
