API SANGEA Version 5.2 GHG Emission Calculation Software Features New Enhancements

  • May 13, 2025

American Petroleum Institute (API) and Trinity Consultants are pleased to announce the release of API SANGEA™ Version 5.2. SANGEA is the electronic greenhouse gas (GHG) emissions calculations tool for the natural gas and oil industry, designed to assist petroleum and natural gas companies with estimating, managing, and reporting GHG emissions. It can also be used to track energy consumption and criteria pollutant emissions as well. Version 5.2 incorporates the following enhancements, fixed issues, and known issue:


Enhancements

  • New Venting Source Type: Added support for the Improperly Functioning Separator Dump Valve as a venting source, in accordance with the 2021 API Compendium. Emissions from this source can be estimated using either emission factors or equation-based methods.
  • Methane Flashing Loss Emission Factors: Incorporated updated methane flashing loss emission factors for crude oil storage tanks, based on the 2021 API Compendium
  • Fuel Gas Composition Import/Export Tool: Introduced a tool that allows users to import and export volume gas composition data for multiple fuel gases simultaneously, improving workflow efficiency
  • “Re-Calculate All” Button for Fuel Gas: Added functionality that enables users to re-calculate properties for multiple fuel gases in one action, using volume gas composition data
  • Updated Reporting for User-Defined Sources: Modified reporting behavior so that all user-defined source types are now reported individually, rather than grouped by module
  • Automatic Database Version Updates: Implemented automatic version control for Microsoft Access database files used in SANGEA, including a notification pop-up to inform users of updates
  • Security Updates: Applied security-related enhancements. These updates do not affect calculations nor the user interface. However, users who do not upgrade to this latest version will be unable to use the license release and unlock functionality moving forward, so it is crucial to update your software today to Version 5.2 if you have not yet.
  • End User License Agreement (EULA): Integrated the API SANGEA EULA into the installation process. Users must accept the license agreement before proceeding with installation.

Fixed Issues

  • Resolved an issue where certain mud degassing source types were not appearing as expected
  • Fixed a stability issue that caused SANGEA to crash under certain system environments when exporting reports

Known Issue

  • An error may occur when users copy an existing source and then attempt to change its source type within the copied source. To avoid this, create a new source instead of copying. For assistance, please contact the Support Team at: support@trinityconsultants.com
