Fig. 5: Operator-specific, methane intensities (considering measured sources only) of delivered hydrocarbons for select (anonymized) operators at specific well battery types.

(a) crude oil single-well batteries, (b) crude oil multi-well batteries, and (c) gas single-well batteries. Methane emissions include measured sources at both facilities and associated wells, and net dispositions of hydrocarbons are calculated from volumetric reporting data (dispositions less receipts) in the Petrinex system. The gray bar in each subplot represents all operators not explicitly plotted. 95% CIs are shown in black with the light green confidence interval upper bounding the effect of source intermittency as in Fig. 2. The horizontal blue line and band represent the mean and 95% confidence interval (including the effect of intermittency) of the relevant facility type across the entire province.
