Wyoming Proposal to Curb Venting and Flaring Needs Work

By Jon Goldstein / Published: November 19, 2015

When operators pull oil out of the ground, it often comes up with copious amounts of natural gas. This “associated gas” can be captured and brought to market, creating an additional revenue source for operators. But if no gathering infrastructure or other methods of capture are deployed, operators either vent the gas to the atmosphere or burn it off with controlled flares. Venting results in the release of methane, a powerful greenhouse gas. Flaring results in troublesome emissions as well, including CO2 and hazardous air pollutants.

According to the Wyoming Oil and gas Conservation Commission (WOGCC), Wyoming’s oil and gas operators vented and flared more than five billion cubic feet of natural gas in 2014. Five billion cubic feet of gas that could be sold to generate taxes and royalties, heat homes and power machinery across the country, instead was wasted. Read More »

Jersey Utility to Use Methane Data Mapped by Google Street View Cars to Target Gas Line Repairs

By N. Jonathan Peress / Published: November 16, 2015

Regulators Bless Plans to Use Information Developed by Environmental Defense Fund and Google in $900M Pipeline Upgrade Program to Improve Safety, Reduce Waste and Cut Greenhouse Gas Emissions

New York and New Jersey, like many older communities in the US, have thousands of miles of old, leak-prone gas lines under their streets, some dating back to the late 1800s. Besides safety concerns, this leaking natural gas – which is mostly methane – is a potent greenhouse gas and a huge waste that’s ultimately paid for by utility customers. While major leaks posing immediate risk are typically fixed quickly, thousands of others can persist for months or years.

Until now, it’s been hard to measure the problem on a large scale, or to use that information to better focus on upgrades with the biggest benefit for the buck. Read More »

A Big Climate Opportunity for Mexico in Dealing with Methane Now

By Drew Nelson / Published: November 12, 2015

Mexico is getting good news today about a strategy it can use to help meet its 25% greenhouse gas reduction pledge by 2030. A new report conducted by energy research firm ICF International found that by using available and low-cost technologies, Mexico can cut 54% of its methane emissions from the oil and gas sector for less than one peso per ton of carbon dioxide. Not only does this keep a very potent greenhouse gas out of the atmosphere, methane is 84 times more powerful than CO2 in intensifying warming, but by capturing it, methane is the main ingredient in natural gas, Mexico wastes less energy.

The Mexican government showed leadership in recognizing the importance of reducing short-lived climate pollutants like methane in its climate pledge to the UN Climate Change Conference. And ICF’s study suggests that reductions in oil and gas methane emissions can be a valuable tool as Mexico considers how it will implement policies to meet its goal. Read More »

Recycling Wastewater from Oil and Gas Wells Poses Challenges

By Dan Mueller / Published: November 11, 2015

Each year, the oil and gas industry produces more than 800 billion gallons of wastewater. Coupling the massive volumes of wastewater generated over the life of the well and the millions of gallons of water needed to hydraulically fracture each well, it’s easy to see that oil and gas exploration and production is just as much a water issue as it is an energy issue.

With growing frequency, this huge volume of oil and gas wastewater – which contains hundreds of chemicals resulting from operations as well as underground water that is usually heavily laden with salt and naturally-occurring pollutants – is being recycled, and some groups are pushing for mandatory recycling policies. Sounds great. After all, recycling is good for the environment, right? Read More »

Cameras, Drones and Lasers: How They’re Tackling Oil and Gas Pollution

By EDF Blogs / Published: November 11, 2015

Dr. Jason Gu was still a graduate student when he developed the technology behind SenSevere, a start-up that creates laser-based gas sensors for use in heavy industry and power plants. Today, he’s working to apply this technology to methane emissions from the oil and gas industry, making him one of the many entrepreneurs developing solutions to tackle the problem. His fascination with innovation isn’t just making his clients more efficient—it may also be saving the planet.

The hidden cost of methane

Methane, the main component of natural gas, is a powerful pollutant responsible for a quarter of the global warming we feel today. The oil and gas industry releases 7 million tons of it into the atmosphere every year through emissions from oil and gas fields and associated pipelines, resulting in over a billion dollars’ worth of wasted American energy resources. And, toxic chemicals like benzene, a known carcinogen, can accompany methane emissions, posing a potential threat to public health.

“The industry is beginning to become more sensitized to the fact that methane is an aggressive greenhouse gas,” said James Armstrong, president of Apogee Scientific, a Colorado-based methane mitigation company. For more than 15 years, Apogee has manufactured a methane detection system that uses a vacuum and infrared sensors and can be mounted to trucks, ATVs and helicopters to identify leaks in the field. “If you find the leaks and repair them, you’re not only helping the environment…you’re extending the resource.” Read More »

Cutting Oil and Gas Methane A Key Pillar of Global Climate Strategy, Says IEA

By Drew Nelson / Published: November 10, 2015

Today, the International Energy Agency (IEA) released its latest World Energy Outlook, which projects how global energy systems will evolve between now and 2040 and estimates their relative impact on the climate. This annual report always offers important insight into where some of the world’s top experts see the global energy sector heading. But what’s particularly striking this year is its highlight on oil and gas methane, among other interesting conclusions.

The report confirms and builds on IEA’s findings from earlier this summer — that global emissions could peak by 2020 without slowing economic growth, and that reducing methane emissions from the world’s oil and gas industry is one of the fastest, biggest opportunities to make significant climate progress now.

In particular, the gas chapter includes this important takeaway:

“The oil and gas sector is the largest industrial source of methane emissions, a potent contributor to climate change. Outside North America, the absence of robust policy action in this area represents a major missed opportunity to tackle near-term warming. The available evidence suggests that a relatively small number of emitters may account for a large share of overall emissions, but tracking and fixing these leaks – which can be short-lived and intermittent – requires a systematic effort of measurement, reporting and monitoring, backed up by effective regulation.” Read More »
