Carry has some interesting theories on this. If we suck it up commercially from wells, it won't seep to the surface etc.

It could be any of the above... the old mechanic who taught me much of what I know had a specially set aside corner in his yard where he poured & then buried motor oil. A high water table would force something like that to the surface.

BTW, check your deed for any strange "mineral rights" clauses-- a house I bought years ago for The Front Porch ( one of my stores ) had a specific clause which meant that any oil, gas, or valuable minerals were not mine, but reverted to the former owner. Didn't mean a damn thing in practice, since no such deposits existed, but the seller was covering all his bases.
