Oil field equipment can consist of many things. I would like to explain some of the largest oil field equipment.A land rig and an off shore rig and the difference between the two.
A land drilling rig can consist of a rig on wheels(one that can be moved under its own power) and one that is set up with a crew. Some land rig are very large. It can take up to 77 rail road cars to transport a land rig from place to place. The cost to move one is very costly.

Trasportation of about 60 miles can easily cost $250,000. To move a large land rig from one continent to another can easily cost over 1 million dollars. A land rig can be leased or rented the price for a small rig can be just hundreds of dollars a day. While a large rig can be as much as $29,0000 per day. A small rig total cost to buy, would cost approximately thousands of dollars. while a large rig can easily be over 20 million dollars. The smaller rig can be just hundreds of horsepower will a large one can easily be over 3000 hp. The depth of a small rig is just a few hundred feet while a larger rig can easily drill over ten thousand feet.
It is very hard to give a price with out a lot of detail.
A drilling land rig is a oilfield equipment which produces holes (usually called boreholes) and/or shafts in the ground. Drilling land rigs can be massive structures housing equipment used to drill oil wells, or natural gas extraction wells. They test sub-surface mineral deposits, test rock, soil and groundwater physical properties. Drilling land rigs can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land not to be confused with marine-based structures (such as oil platforms, commonly called ‘offshore oil rigs’). The term “rig” therefore generally refers to the the total structure that is used to penetrate the surface of the earth’s crust.
