Depending on the meter - If you install it up-side down it will spin in reverse. How do I know? Well once in a big rush I put on in that way, and got a call from the poco to put it back the right way....
Never heard of generation from an oil well, but hey, anything is possible. Weather or not this was the intent is a question that looms for me, as it is drawing on the up-stroke. There may be actually something wrong here - the motor may be generating unintentionally.....
