Drilling rigs come in many different sizes. You can find the information here at Oilfield Equipment
Drilling rig is a specialized field. You have to have special equipment and specially trained employees. There are two types of drilling rigs, water based and land based. Oil rigs are huge. They have large mud pumps that circulate the slurry or drilling mud. The mud is sent down the drill pipe to the drill bit. This keeps the drill bit cool and removes the rock fragments as the well is drilled. which is used to hoist the drilling equipment. Other equipment is used to extract the oil or natural gas laterThe oilfield equipment used to extract the oil/natural gas come later}. Because of the remote locations of the rigs, a camp is required . All of can be considered part of the drilling operation.
Offshore oil rig construction needs to have everything. To get more information on Oilfield Equipment This includes a place to live to the oilfield equipment required to process the oil. A platform that is fixed is built on steel or concrete legs that are anchored directly into the seabed. The oil deck has space for oil rigs, oil production facilities and crew accommodations. A compliant tower is also a fixed structure. Platforms that can be semi-submersible have legs with that are supported by a pontoon structure under the water. The platform can be moved as need be. They are anchored by cable anchors when not being moved.
An oil rig on on shore would seem to be far more easier to make then one on the ocean. However every oil rig has the elements to work with. With the complexity of the building a rig, there are many hurdled. rigs were structures that did not move. The structures were built on site and were not removed when the well was drilled.Modern oil rigs are custom-built and are movable. Once the well is completed the rig will be moved to a new location. It can take weeks to move an oil rig as they have to be taken apart and moved. It takes time but is less wasteful then building derricks for every well.
Drilling rigs need to bore holes or tubes into the earth. The more elusive oil is the more effort is put into harvesting it. Deeper oil wells are dug requiring specialized equipment. The deeper the hole the more specialized the equipment. Having an oil rig does not just involve digging a well and pumping the oil out.
Jack-up rigs are the most common drilling platform. The structure is supported by long legs from the ocean floor. At the new site, The legs once again, are lowered to the sea floor. A tension-leg drilling platform can be moved using tether at each end. A Spar drilling platform has about 90% of its structure underwater. It is held up by a cylinder. It works under the same principle a buoy does. Each one of these oil rigs meets a different need or Pump Jack.
