Site-specific Site Configurations for thousands of sites in a basin would require detailed information for every site, which requires significant effort and engagement from site operators; this not scalable for widespread usage. However, every production facility is not uniquely designed. Operators use common 290 designs across many sites, often modifying the facility size by replicating one separation train design to match the number of wells connected to one facility. Further, each revision of production site designs typically reflect regulations in effect at the time of design, coupled with the latest in production process technology. After construction, production facilities are infrequently modernized in a major way. Therefore, while there are thousands of sites in a basin, the site configuration of most sites can be categorized into a 295 relatively small number of prototypes which capture the facility design in sufficient detail for highly accurate temporal simulation of emissions.
