The Oil Production Greenhouse gas Emissions Estimator (OPGEE) is a life cycle assessment (LCA) tool that is used to measure greenhouse gas (GHG) emissions from the crude petroleum processes including production and transportation. The system boundary of OPGEE assessments span well-to-refinery from the initial exploration to the arrival at the refinery.

Description
The Oil Production Greenhouse gas Emissions Estimator (OPGEE) is a life cycle assessment (LCA) tool that is used to measure greenhouse gas (GHG) emissions from crude petroleum processes including production and transportation. The system boundary of OPGEE life cycle assessment of GHG spans well-to-refinery from the initial exploration to the arrival at the refinery gate.

Development
Under the leadership of Adam R. Brandt at Stanford University's School of Earth, Energy & Environmental Sciences, researchers developed the Oil Production Greenhouse gas Emissions Estimator (OPGEE) an open-source oil-sector carbon intensity (CI) modeling tool.

Usage
California air regulators use OPGEE to "estimate emissions from different crudes that California imports or produces as part of the state's low-carbon fuel standard.

Masnadi et al used the OPGEE for their 2018 Stanford study.
