Cenovus Reports Success With Airborne Lasers in Fight Against Emissions

In the search for leaks, more oil and gas companies are making the argument that ground-based inspections cannot compete with aerial surveys.

Cenovus Energy and Bridger Photonics this week highlighted their use of an emergent airborne-based methane monitoring technology that has helped “make sizable reductions” in the oil and gas company’s emissions.

The nod of approval comes nearly 2 years after the Calgary-based operator first partnered with the US-based technology developer in a pilot project to identify methane emissions across its conventional oil and gas production sites.

Bridger Photonics specializes in the use of light detection and ranging (LiDAR) sensors that are mounted on small aircraft to generate 3D maps of oil and gas fields. These maps are used to pinpoint the leaks and to quantify the methane concentrations found above the surface.

Cenovus turned to the LiDAR technology as part of a voluntary program overseen by the Alberta Energy Regulator called the Alternative Fugitive Emissions Management Program, or Alt-FEMP.

Cenovus and Bridger Photonics did not share details on the volume of reductions achieved thanks to the Alt-FEMP pilot. But in regulatory filings, Cenovus said the approach should result in about 200 MMcf fewer annual methane emissions—fugitive and vented—compared with Alberta’s default regulatory approach.

“Using the Gas Mapping LiDAR technology to identify methane emissions has enabled us to make sizable reductions. However, we still have more work ahead of us as we take meaningful action to reduce our overall greenhouse-gas emissions,” said Sean Hieber, emissions management engineer for Cenovus, in a statement on the partnership.

Cenovus, which is aiming to achieve net-zero greenhouse-gas emissions by 2050, has previously pointed out that traditional regulatory programs on methane monitoring require ground-based surveys. Though effective, the operator cites the ground-based methods as more costly and time-consuming than aerial surveys which enable far more sites to be assessed over the same period of time.

With multiple aerial surveys performed each year, one of the program's priorities has been to use the data to identify Cenovus' top 10% emitting locations and quickly follow up with site-specific emission reduction action plans.

In its latest sustainability report from March, the Albertan operator lists the LiDAR pilot as a successful component of its wider program that reduced methane emissions in 2021 by 520,000 metric tons compared with 2020 levels. Cenovus and Bridger Photonics will complete the final round of their 2-year pilot in December.

Bridger Photonics has worked for several other North American operators including large US shale producers Devon Energy and Chesapeake Energy. Last year, ExxonMobil received the first-ever approval from the US Environmental Protection Agency to use Bridger Photonics’ LiDAR techniques in lieu of using ground crews to inspect its onshore facilities by hand to identify methane leaks.

Williams Exec Says More Industry-Led Certified Natural Gas Initiatives Needed to Build ‘Common Currency’

 

By Jacob Dick  October 20, 2022

U.S. industries will need more independently certified natural gas to reach climate targets, Williams’ Brian Vogt, director of new energy ventures, said, but first, companies have to build trust in low-carbon fuels.

Vogt said a lack of transparency and established measures in the certified natural gas space have left investors and international LNG buyers skeptical as shareholders pressure companies to establish environmental, social and governance (ESG) goals.

Natural gas firms need more data to back up claims about the role of U.S. gas as key to lower carbon emissions, but a consistent scale and language that customers can use to understand why they should place value on independently certified gas, Vogt said.

“There is a common phrase: ‘we don’t have the data,’” Vogt said at LDC Gas Forums’ Gulf Coast Energy Forum. “We have to get a common platform, common sense and common currency process in place.”

In the absence of federal regulations or policies to build infrastructure for a central certified gas platform, Vogt said the responsibility – and the opportunities that come with it– will fall to industry. He pointed to the progress Williams has tracked in the industry over the past two decades, as natural gas volumes in the United States have ballooned while emissions have fallen thanks to voluntary reduction efforts.

Tulsa-based Williams’ pipeline network handles about 30% of U.S. natural gas volumes. It recently signed a partnership with PennEnergy Resources LLC to increase certified natural gas supplies from the Appalachian Basin. It also has partnerships to move certified natural gas in the Haynesville Shale with Quantum Energy Partners.

Now, it is creating pilot programs to further track and verify gas that enters its pipeline network. Developed in partnership with Context Labs, Vogt said the pilots are designed to break away from the issues causing confusion and doubt over current verification methods.

“There has always been a question about what standard or label makes sense to use,” Vogt said. “We think using the data is what makes sense.”

Context Labs’ Rebeca Quintanilla, global head of origination, said her company specializes in creating data systems at scale, but the end result is focused on creating something customers can use to verify a company’s claims.
“There are only so many tools to reduce Scope 3 emissions as a utility,” Quintanilla said, referring to the indirect emissions associated with products or fuel a company may use in their business. “Creating a market mechanism and a common currency is really the only way to enable end users to have that choice and knowledge.”

Vogt said Williams first applied its program to its Haynesville assets. U.S. natural gas demand is expected to grow more than 19 Bcf/d by 2031, with more than 12.9 Bcf/d coming mostly from liquefied natural gas projects in Louisiana and Texas, according to data from Wood Mackenzie.Williams recently sanctioned the Louisiana Energy Gateway, a 1.8 Bcf/d system designed to move Haynesville supply to industrial markets and for export.
