oil rig machinery

The artwork depicts an oil rig machinery, commonly known as a nodding donkey or pumpjack. It is a type of machine used to extract petroleum from the ground. The machinery is set against a backdrop of a grassy field and blue sky. The main components of the oil rig machinery are the horse head, the walking beam, the pitman arm, and the wellhead. The horse head is the large, triangular-shaped piece of metal that sits at the top of the rig. The walking beam is the long, horizontal piece of metal that connects the horse head to the pitman arm. The pitman arm is the shorter, vertical piece of metal that connects the walking beam to the wellhead. The wellhead is the pipe that connects the oil rig machinery to the underground oil reservoir.
