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you have to cut your oil production in some proportionate manner (oil is the more desired product) - though that was rescinded during the last big price down turn and am not sure if that is back in effect.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.
