CO2 Intensity of Drilling Oil Wells?

This data-file estimates the CO2 intensity of drilling oil wells, in our usual units of kg/boe. The calculations are conducted bottom-up, based on fuel consumption at onshore, offshore and deep-water rigs; plus drilling days and typical resource volumes per well.

Drilling wells is not the largest portion of the oil industry’s total CO2 intensity. Nevertheless there is a 50x spread between the best and worst barrels, which is wider than other categories we have screened.

Prolific fields will have the lowest drilling-CO2 intensities, particularly where they are onshore (e.g., Saudi Arabia). Infill wells at mature deepwater fields may have the highest drilling-CO2.
