The Environmental Partnership launched in late 2017 with 26 members. Within 12 months, it more than doubled in size to 58 members — including 32 of America’s top 40 oil and gas producers. Today, its members account for nearly half of America’s oil and natural gas production. The group focuses on cutting emissions of methane and other greenhouse gases known as “volatile organic compounds.” Without proper monitoring and maintenance, these gases can escape from drilling rigs and pipelines and contribute to global warming.
Even before the partnership formed, firms were spending millions to reduce their carbon footprints. Methane emissions have plummeted in America’s largest energy-rich basins, even as oil and gas production has spiked. But firms in the Environmental Partnership weren’t satisfied with that progress.
First, the partnership focused on updating outdated technology such as high-bleed pneumatic controllers. Pneumatic controllers regulate temperature, pressure and liquid levels at natural gas sites by opening or closing valves. To operate these valves, the controllers rely on pressurized natural gas. As their name suggests, high-bleed pneumatic controllers can release relatively large amounts of natural gas, along with methane and volatile organic compound byproducts, into the air.
The Environmental Partnership plans to replace all high-bleed pneumatic controllers in five years. And it’s well on its way to doing so. It replaced, retrofitted or removed more than 28,000 prior to 2018 and an additional 3,000 last year. As a result, nearly 40 participating firms don’t use high-bleed controllers at all.
Second, the partnership set out to curb methane leaks — which can sometimes happen as firms extract, store and burn natural gas. Methane is both a potent greenhouse gas and the main ingredient in natural gas. Participating companies conducted more than 156,000 surveys across 78,000 production sites, inspecting more than 56 million individual parts.
After thorough inspections and repairs, the Environmental Partnership found just 0.16 percent of industry parts contained leaks — and member firms repaired 99 percent of those in 60 days or less.
Participating firms also worked to better monitor liquid removal from natural gas wells. When too much liquid, mostly consisting of water, builds up within gas wells, firms manually direct the liquid to vents that bring it to surface. During that process, methane or volatile organic compounds can potentially escape into the atmosphere. Over the course of 2018, the Environmental Partnership oversaw more than 130,000 manual removals to ensure environmentally safe execution. Methane emissions from natural gas systems fell more than 14 percent between 1990 and 2017. The Environmental Partnership’s initiatives will undoubtedly cut these emissions even further.
Energy firms are weaponizing their data and tools for the common good. Let’s hope they keep up the fight in the war against climate change.
