JANUARY 2017 | DATA-DRIVEN OIL FIELDS | EPMAG.COM 34 AUTOMATION Automating GHG Reporting Procedures Solutions to automate data collection, integration and reporting can save producers time and money. By Hong Qin, Paul Glaves and Jonathan Chen Wood Group T he U.S. Environmental Protection Agency (EPA) has contin- ued to tighten its reporting requirements for greenhouse gas (GHG) emissions data from onshore natural gas producers. Under its 40 CFR Part 98 mandatory reporting rule, producers are required to report true, accurate and complete emissions to the best of their knowledge. Since the methodology for calculations is mandated in the rule, quality of the input data is critical for a compliant outcome. GHG rules continue to change Recent addendums to the regulations have made them more onerous and exacting. Subpart W, which included any annual emitter of more than 25,000 metric tons of carbon dioxide equiv- alent (CO 2 e), has added gathering lines and booster stations to the processing, production and storage aspects of the industry. First data submission under this rule was required in January 2017. Further, Subpart OOOO (Quad O) has also been added to address restrictions on specifi c VOC sources including com- pressors, leak detection equipment, storage vessels and hydraulic fracturing equipment at the wellhead. The volume of data collected as required for rule compliance is enor- mous. As an example, a major operator reporting on a single a southwestern U.S. geographic asset of approximate- ly 9,000 well sites had more than 1.2 million data points annually, or more than 130 per well site. The problem is more than just volume The gathering of the information usually falls on the producer's envi- ronmental group which is most often overwhelmed by this labor-intensive activity. In addition to the sheer vol- ume, the data has been tracked by separate functional groups for their own purposes. These disparate pieces of information might in- clude equipment inventory, well production data, operating in- formation related to engine run times or non-system data includ- ing well fl owback events from hydraulic fracturing or workovers. Historically, the environmental group personnel relied on spe- cially purposed macro-driven spreadsheets for accumulations. This function fi rst had to be tailored to address differences in terminology and formats used by various departments throughout the orga- nization. Even when standardized, the output results were usually incomplete, inconsistent and delayed. Quality assurance to totally compliance with regulations was sorely lacking. Furthermore, other than for mandated regulatory reporting, the information provided little value to the operation of the asset or its overall management. The automated solution The producer enlisted a centralized data warehouse and busi- ness logic software as the initial part of its solution to automate the collection, integration and reporting, all with an emphasis on quality assurance and usefulness to management.
