Natural Gas Engine : McClintock  

You would be wrong. They don't do that anymore. The gas is produced with the oil. The casing is tied into the production system and separated at the tank farm. Oil and water separated with the gas going to gas plant and oil out the last or tank farm to transport to refineries. Water to disposal wells.

This is cheaper than running electrical infrastructure for the entire lease.

A big enough company and undepleteded gas reserves would build a co generation plant and then electrify the field.

Description says "arrow" engine.

@@elonmust7470 it’s definitely an Ajax engine. It’s probably a 7 1/4 x 8 or model EA-30. 30hp. These are two cycle engines. Arrow C series engines are four cycle. Arrow does make two cycle engines, but they have two cylinders.

@Elon Must it's an Ajax engine.

Arrow would be Fairbanks Morse clone.AL B.

Yeah, I'm calling it an Ajax. A guy in western PA has really nicely restored one that he shows.

Honda Montesa

I thought so just as I hit the send key! Thanks for the reply.

If they could find it....

I'm wearing a helmet, eye protection and hard toe boots, carry a methane detector and keep and eye out for rattlesnakes. I've worked on active drilling rigs, both on and offshore, around production equipment, using high explosives and radiation, and coping with high pressures and flammable fluids and gases. It _is_ dangerous being around big moving pieces of metal. I've been too close to two blowouts. Thank you for your concern! Most people around here use natural gas from these wells to heat their homes, cook their food and generate electricity, so it would be counterproductive to damage equipment, and readily detected.
