So there only needs to be a bit of concrete in a smaller structure that exceeds bunker-busting bomb specs and 'funnels' (?) the natural gas to a tank or a bladder?

Are there existing methods for capturing methane from insufficiently-capped old wells?

Are the new incentives/fees/fines enough to motivate action thus far in this space?

OpenAPI is one way to specify integrable APIs. An RDFS vocabulary for this data is probably worthwhile; e.g. NASA Earth Science (?) may have a schema that all of the state APIs could voluntarily adopt?

Presumably the CophenHill facility handles waste methane? We should build waste-to-energy facilities in the US, too

FWIU Carbon Credits do not cover methane, which is worse than CO² for #ActOnClimate

Natural gas isn't stored on site, it needs to be piped to the nearest plant to be processed and put into a sales line. Capturing methane from insufficiently capped old wells would not be economic in most cases. If a company was called out on it, they would just go dump more cement in it to make sure the gas is contained. 90% of the time, wells that are plugged are plugged well, the ones that aren't and are just abandoned maybe leak only 1-5 thousand cubic feet per day - nothing worth doing anything about (to the company financially). Fines typically mean nothing to E&P with where they are now - though some have gotten clever about it - example being North Dakota keeps flaring down by whatever you are flaring you have to cut your oil production in some proportionate manner (oil is the more desired product) - though that was rescinded during the last big price down turn and am not sure if that is back in effect. To your statement about APIs - that is one thing the oil industry is terrrrrrible with. Our data collection and cleaning is abysmal. I agree with your statement, and I would be all for it, but E&P companies can't even get their own production numbers right - a good example is if you check out the fracfocus database where companies volunteer up their fracturing job compositions. Generally it is useful, but the people who input the data, similar to who would probably be handling this can barely spell and data cleaning would be a nightmare. waste to energy facilities are great, and there are some interesting things out in the oilfield but, like everything else, there needs to be more financial incentive for companies to build them/use them.

So, in 2022, it's cheaper to dump concrete than to capture it, but the new fines this year aren't enough incentive to solve for: capture to a tank and haul, build unprocessed natural gas pipelines, or process onsite and/or fill tankers onsite?

How long should they wait to up the methane fee if it's not enough to incentivize capping closed wells?

It is totally cheaper to dump some cement (it is mostly gel with a topping of cement). To P&A older wells maybe runs $12-25K (assuming, like, a 5-8k ft. depth conventional well)...and I may be running a little high on that number. That gets a small truck out there with a small crew to pull tubing and dump alternating layers of cement and gel (cement goes on the top and across formations that would be ground water bearing). Fun fact, if you have to go back into an abandoned well and you come across red cement at the top, that is indicative of someone losing a nuclear based well tool in there and to call someone before going further. A typical 7.5-10k foot lateral unconventional well (horizontal wells) down that way will run about $7-8 million depending (and 6 wells on average on a well pad), but aren't really the issue, but just giving you some numbers to sort of show that fining someone $100K for something serious isn't that big an expense and not really a deterrent. Natural gas lines are always a big deal to oil and gas companies - if you build it they will come. Most space in pipelines for operators is spoken for before they even dig the first trench.

Options:

A. Privately and/or Publicly grant to P&A wells

    ($25k+  * n_wells)
  + ($7-8m+ * m_wells)

B. Build natural gas pipelines that run past those well sites (approval,)

C. increase the incentives/fines/fees

Shouldn't it be pretty easy to find such tools with IDK neutron detection and/or imaging at what distance?
