Oil field equipment can is a broad subject. I would like to explain some of the largest oil field equipment. the difference between a land rig and a off shore rig.

A land drilling rig can made up of a rig on wheels( one that is mobile under is own power and one that is set up with a group of people. Some land rig are very large. It can take up to 77 rail road cars to transport a land rig from one place to another. 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 1-2 million dollars. A land rig can be rented or leased the price for a small one can be just hundreds of dollars a day. While a large one can be as much as $29,0000 per day. A small rig total cost to buy, would cost around thousands of dollars. while a large one 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.

You see why their is a large ...

A land rig is a 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 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 complex of equipment that is used to penetrate the surface of the earth's crust.
