Measuring Methane Emissions

The American gas industry faces growing pressure from investors and customers to prove that its fuel has a lower-carbon provenance to sell it around the world. That has led the top U.S. gas producer, EQ , and the top exporter, Cheniere Energy to team up and track the emissions from wells that feed major shipping terminals. The companies are trying to collect reliable data on releases of methane—a potent greenhouse gas increasingly attracting scrutiny for its contributions to climate change—and demonstrate they can reduce these emissions over time.

“What we’re trying to really do is build the trust up to the end user that our measurements are correct,” said David Khani, EQT’s chief financial officer. “Let’s put our money where our mouth is.” Natural gas has boomed world-wide over the past few decades as countries moved to supplant dirtier fossil fuels such as coal and oil. It has long been touted as a bridge to a lower-carbon future. But while gas burns cleaner than coal, gas operations leak methane, which has a more potent effect on atmospheric warming than carbon dioxide, though it makes up a smaller percentage of total greenhouse gas emissions.

Investors, policy makers and buyers of liquefied natural gas, known as LNG, are rethinking the fuel’s role in their energy mix …Those concerns, pronounced in Europe and increasingly in Asia, are a problem for LNG shippers, as some of their customers signal plans to ease gas consumption over time…Nearly every industry now faces some pressure to reduce its carbon footprint, as investors focus more on ESG—or environmental, social and governance—issues and push companies for trustworthy emissions data. But the pressure has become particularly acute for oil-and-gas companies, whose main products contribute directly to climate change.

The companies and researchers plan to test drones, specialized cameras that can see methane gas, and other technologies across about 100 wells in the Marcellus Shale in the northeast U.S., the Haynesville Shale of East Texas and Louisiana, and the Permian Basin of West Texas and New Mexico. EQT has said it would spend $20 million over the next few years to replace leaky pneumatic devices, which help move fluids from wells to production facilities and water tanks, with electric-drive valves, executives said. They expect that will cut about 80% of the company’s methane emissions. The company also began exclusively using electric-powered hydraulic fracturing equipment last year.
