The article mentions that the vehicles are run on either diesel or natural gas. Are you saying that the vehicles are specially designed to take gas right out of the ground or that the article doesn’t mention that the portable CNG trucks have to take their CNG to a secondary refiner before it can be used by the drilling company vehicles.
