- Emissions Reporting Tool for Oil & Gas Industry


Since the early 2000’s, the American Petroleum Institute (API) has sponsored the SANGEA software tool for the oil and natural gas industry to quantify greenhouse gas (GHG) emissions and standardize emissions reporting. The information from SANGEA is used for API GHG benchmarking studies, industry climate change reporting, as well as for submissions to address federal GHG emission mandatory reporting for the petroleum industry.

Regulatory changes, including mandatory reporting requirements for GHG emissions, prompted API to sponsor a major overhaul of the software including current calculation methodologies. API selected Trinity Consultants/T3 to update the software including these functionalities:

  • Apply the API Compendium 2009 for GHG emission calculation methods
  • Incorporate the U.S. EPA Mandatory Reporting Rule (MRR) Subparts C, P, W, and Y to comply with U.S. regulatory reporting requirements
  • Store source parameters and operating data through established procedures
  • Calculate direct and indirect GHG emissions as well as criteria pollutants with embedded emission factors and equations
  • Track energy consumption and normalizes emissions on a production basis (e.g., ton GHG/bbl of product)
  • Report GHG emissions to comply with regulatory requirements and/or to track corporate performance metrics

SANGEA can also be used to track energy consumption and estimate criteria pollutant emissions.

SANGEA calculates and compiles GHG emissions and energy usage data from exploration and production, gas processing, refining and marketing, petrochemicals, transportation, electricity consumption, manufacturing, coal mining, and other activities.

The desktop database program has a user-friendly interface that can be used to manage various types of sources throughout a large entity to address corporate and/or regulatory reporting requirements. In order to build a solution that would promote long-term software usability and easy maintenance, the new product was migrated from its previous spreadsheet-based application to stand-alone software in Microsoft .NET framework with Access database files for storing source information.

In addition to being user-friendly, SANGEA improves usability with these features:

  • Enter data using setup wizards
  • Create, delete, and edit sources quickly
  • Import/export data manually or use batch transfers
  • Organize data and information by fuel, sources, or activities
  • Copy source parameters from an existing file

SANGEA provides calculation methodologies in various modules that are grouped based on API’s Compendium 2009 and corresponding subparts of the U.S. EPA’s MRR for GHG emissions. Two GHG reporting protocols with numerous source types are integrated into one software tool. The following table shows the source “modules” available in SANGEA.

The software also includes U.S. EPA AP-42 emission factors for criteria pollutants, which enables users to quantify emissions for both GHG and criteria pollutants.

Under each module, wizards help users set up emission sources and multiple calculation methods without referring to the methods in the protocols. The software guides users to specify source parameters that are needed for GHG emissions calculations and/or reporting requirements. These source parameters are stored in the software source database for future emission inventory reports.

SANGEA also offers a “User Defined Sources” module under the API Compendium protocol that allows users to define sources that are not already established in the two protocols of the SANGEA reporting system.

Multiple locations can be created under one SANGEA working file. This allows companies to report emissions by business operating groups, geographical regions, or regulatory reporting entities.

The software tool incorporates more than 20 reporting formats, including emission calculations, detailed monthly source emissions, API summary, MRR summary, Subpart W, Subpart Y, and others.

T3 was launched in 1995 when Trinity Consultants, an international leader in environmental consulting, responded to client needs by focusing on the specialized area of EH&S management solutions. Today T3 is an industry leader with a rare mix of EH&S professionals and IT experts. This powerful combination gives T3 unmatched capability in applying technology to solve industry’s EH&S information management challenges.
