Wellhead locations and production rates for 2021 were acquired from Colorado Energy and Carbon Management Comission (ECMC) data portal in January 2022. Well locations were clustered by distance, resulting in wellhead clusters ranging from 1-24 wellheads (Figure ). The wellpad and wellhead cluster facility types represent a wide range of complexity, from a single wellhead far from any other facility, to integrated wellpads including 1-4 wells, to wellhead clusters of 2-24 wellheads distant from other well pad equipment. Across all facility types, ECMC wellhead reports provided metadata for 7,041 facilities (56%).
