Sempra LNG Joins Methane Emissions Group US-based Sempra LNG said March 9 it has joined the Collaboratory for Advancing Methane Science (Cams), an industry-led consortium created to better characterise and understand methane emissions. The consortium, created in 2018 and administered by GTI, includes US majors Chevron and ExxonMobil, Norway’s Equinor, Anglo-Dutch major Shell, Pioneer Natural Resources and LNG developer Cheniere Energy. Its members “work collaboratively to provide actionable, transparent methane science to contribute to the understanding of methane emissions across the oil and gas value chain and inform mitigation strategies,” according to an email statement. The consortium’s first project was the Methane Emission Estimate Tool (Meet), an open-source model that simulates methane emissions from production and gathering facilities. Phase two of the Meet project will apply the tool to simulate areas of higher methane concentrations for Project Astra, a project led by the Center for Energy and Environmental Resources at the University of Texas that is creating a regional network of sensors to monitor methane emissions.
