Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 13 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Bredariol: IEA estimates global flare combustion efficiency at 92%, not industry-claimed 98%
“We at the International Energy Agency estimate that the combustion efficiency of flares globally is at around 92%. That's a much lower number than what you might hear from the industry. They will often refer to 98%, but it's in line with several scientific stu…”
Bredariol: Most global flaring sites are within 20 kilometers of existing pipelines
“When we look at, you know, the 8000 or more flaring sites across the world. And we take into account existing pipelines, demand centers, and other characteristics. The majority of these sites could probably use a connection to a pipeline. Many of these are act…”
Bredariol: US gas flaring increased 20% in 2023, primarily in Permian Basin
“In the United States, flaring increased by about 20% last year, and most of this increase came from the Permian Basin.”
Bredariol: Rapid production decline disincentivizes gas pipelines at unconventional oil wells
“Unconventional Oil wells, they produce relatively small volumes of associated natural gas, and they produce it for a relatively short amount of time. The volume decreases quite rapidly, as does with oil, right? And so they don't have, the operators don't have …”
Bredariol: 2023 global gas flaring exceeded Norway's total annual natural gas production
“So we have about a hundred and fifty billion cubic meters of natural gas being flared last year. These are the latest data from the World Bank. And if you want a comparison point, Norway's natural gas production was about a 120 billion cubic meters. So we flar…”
Bredariol: Global flaring emissions exceed all international flights combined
“Considering a global warming potential for methane of 30, that's in a hundred years timeframe, that would be over five hundred million tons of CO₂ equivalent. That's more than all international flights last year. And it's just a bit below all the CO₂ emissions…”
Bredariol: Nine countries account for 75% of global gas flaring
“For over decades, Gas flaring around the world is concentrated in nine countries. That's Russia, Iran, Iraq, the United States, Venezuela, Algeria, Libya, Nigeria, and Mexico. If we look at data for last year, these top nine countries were responsible for abou…”
Bredariol: Most oil facilities run on diesel replaceable by on-site natural gas
“If you look at the industry as a whole, most of the facilities are running some amount of diesel generation, and that could be replaced by natural gas.”
Bredariol: Offshore flare mitigation is essentially limited to LNG
“All of those options are more on the table for onshore. Maybe offshore you can do LNG, but otherwise all of those options are kind of off the table.”
Bredariol: Small-Scale GTL and Gas-to-Methanol Face Cost Disadvantages Versus CNG and LNG
“Gas to methanol and gas to liquids in general, they are much more expensive projects. I would say that in general, just as broad lines, it will certainly depend on the details of the project. You would go from Mini-CNG to Mini-LNG to GTL. In terms of prices. S…”
Bredariol: Continuous routine flaring accounts for roughly 70% of flared gas
“So maybe two thirds or 70% of all flared volumes are these continuous flares that are operating every day and are essentially a way to get rid of this associated gas.”
Bredariol: Most Flaring Volume Comes From Middle-Sized Flares
“If you look at kind of the general distribution of flares, most of the volumes are in what you might call middle-sized flares, but there's a large contingent which is small flares. And then it's where the economics might become a bit more challenging.”
