The drilling rigs are complexes of mobile equipment which can be moved (onshore and offshore) from one drill site to another, drilling a series of wells. In rotary drilling the rock is bored using a cutting tool called the bit, which is rotated and simultaneously forced against the rock at the bottom of the hole by a drill string consisting of hollow steel pipes of circular section screwed together. Offshore drilling is the process of extracting petroleum from reserves located beneath the Earth's oceans instead of reserves located on the mainland. Offshore oil rigs have developed greatly over the past years, and have become gigantic structures that house hundreds of people at a time. Offshore drilling has additional constraints of the depth of water, climatic conditions and the remoteness from the logistical base. The main difference between onshore and offshore drilling is related to the way in which the rig is supported. For the most part, offshore drilling requires the same equipment as onshore drilling. A rig, a drillstring with a drillbit at the end, and a turntable are the essential equipment for drilling. (Along with a power source and the drilling mud that facilitates drilling by cooling and lubricating the drillbit). Onshore oil production drilling, holes down into the earth surface to reach the oil below without the trouble of deep water between the platform and oil. The ground has a solid base in nature so, the drilling structures and areas are well-stacked directly on the soil. The facts are that onshore production is a process that produces fabulous results for the oil and gas industry. The reason for this is that resources are just more plentiful on land. Currently, 70 percent of the world’s oil and gas comes from onshore sites, with 30 percent being produced offshore. Even though offshore sites can be a source for fuel, there is clearly a method between the two that is more reliable. There are two main types of onshore drilling. Percussion, or ‘cable tool’ drilling, consists of raising and dropping a heavy metal bit into the ground, effectively punching a hole down through the earth. Cable tool drilling is usually used for shallow, low pressure formations.

Everyone talks about fracking, but that's only one step of a larger process. Check out and access roads—are built, setting up the land for the next step: drilling.

Oil well drilling continues to slightly outpace gas well drilling. similar purposes such as the study of sedimentary basins (7 holes), geothermal processes (4), This may involve drilling additional wells. Various processes are used to prolong the productive life of an oilfield and production in the UK. Primary recovery occurs 1 Apr 2010 What happens during the drilling process?

Onshore drilling accounts for 70 percent of the worldwide oil production. Onshore oil production requires the drilling of deep holes down into the earth’s surface to reach the oil below, much like offshore drilling but without the difficulty of deep water between the platform and the oil. The process begins by drilling a hole deep into the earth. To do this, a long bit attached to a "drilling string" is used. The bit varies in diameter from five to 50 inches. After each section is drilled, a steel pipe slightly smaller than the hole diameter is dropped in and often cement is used to fill the gap. Once the hydraulic fracturing process is completed, production can begin, oil and gas can flow from the well bore and the fracturing fluid can be recovered. During initial production of the well, about 25-75% of the fracturing fluid is recovered.

Once a company identifies where oil or gas is located, plans begin to drill an Drilling is the final stage in the exploration process. on whether the drilling is for onshore exploration or offshore.

Onshore land drilling rigs include functions like product manufacturing, examination, assessment of oil gasses and wells of different kinds. The wells can be vertical or horizontal ranging from 1200 meters to 5000 meters in depth. In short, onshore drilling refers to drilling deep holes under the earth’s surface whereas offshore drilling relates to drilling underneath the seabed. These drilling methods are used in order to extract natural resources – usually oil and gas – from the earth. Offshore well drilling is a process of drilling a hole in the ocean floor for extraction of natural resources. It is a challenging part of the exploration and development process that is carried out in several stages.
