Instead of using estimated based on what you think the equipment should take up, perhaps you should take a look at the google maps link your sibling posted, and zoom into some oil wells (the cleared land lots) and use the measurement tool (right click) to get the area of some of them (which it shows if you create an enclosed area). I just measures three, with the following square footage: 443k sq ft, 338k sq ft, 164k sq ft. Each lot looks to have multiple wells, but there's a lot of just cleared empty land for each lot, so I suspect you're being very optimistic on your assessment of how much land is used for each well. The study cited may be overestimating also, but they cite their sources (even if they aren't explaining exactly where they get well land use amount from), so perhaps there's an explanation buried deeper in there.
