Drilling rig A drilling rig is a machine which creates holes in the ground. Drilling rigs can be massive structures housing equipment used to drill water wells‚ oil wells‚ or natural gas extraction wells‚ or they can be small enough to be moved manually by one person. They sample sub-surface mineral deposits‚ test rock‚ soil and groundwater physical properties‚ and also can be used to install sub-surface fabrications‚ such as underground utilities‚ instrumentation‚ tunnels or wells.

3.1 Drilling rigs and technologies 3.1.1 Introduction The term drilling indicates the whole complex of operations necessary to construct wells of circular section applying excavation techniques not requiring direct access by man. To drill a well it is necessary to carry out simultaneously the following actions: a) to overcome the resistance of the rock‚ crushing it into small particles measuring just a few mm; b) to remove the rock particles‚ while still acting on fresh material; c) to maintain

Oil Drilling Have you ever seen an animal covered in sludge‚ helpless and weak? Offshore oil drilling is one of our world’s biggest concerns. Offshore oil drilling is the discovery of finding oil or gasoline resources underwater. Usually the oil is found off the coasts of each continent and can also be found in lakes and small seas. Drilling for oil provides the energy to make fuels for cars and other machinery. Many different platforms can be used for offshore oil drilling such as drill ships

Offshore Drilling Does anything out weigh the importance of our planet’s health? You would be surprised by the number of people who look the other way when it comes to keeping the planet clean. Offshore drilling is just one of the major environmental issues that has existed for many years and still continues to be a problem. The topic of offshore drilling not only touches on environmental issues but also political‚ economic‚ and ethical issues. All of these tie into the huge debate over offshore

Offshore drilling began in 1847‚ in approximately fifty feet of ocean water on top of wooden piers. Since then we have went from having a rig on a wooden piers and a platform 200 – 300 feet in the water to‚ having drilling rigs that can walk themselves and drill at a curve. Within that timeline discoveries of both good and bad‚ devastating and innovative have been made on the subject of drilling oil in the middle of the ocean

everyone love swimming in the ocean and seeing all the pretty sea life? Some people do‚ and when people are offshore drilling they can cause a lot of problems if something goes wrong. The biggest concern by environmentalist is not a spill‚ but the pollution of the air and water‚ damage to the ocean bottom and debris that washes ashore from day-to-day operations of oil and gas rigs. Oil Drilling can lead to jobs being endangered‚ animals dying‚ and damaging the eco system. So many animals are dying because

but people seem to ignore the process of acquiring oil. Oil drilling is a dangerous and risky process. It runs the risk of contaminating the surrounding water and harming the organisms that live in it. The process also emits large amounts of carbon dioxide into the atmosphere. The Deepwater Horizon Oil Spill‚ better known as the BP oil spill‚ was a prime example of how oil drilling is an extremely harmful process. An explosion on the rig caused it to spill 60‚000 barrels of oil per day into the Gulf

On April 20th‚ 2010‚ an oil rig exploded in the Gulf of Mexico. As a result‚ approximately 4.9 billion barrels of oil poured into the gulf over the course of 87 days. This tragedy resulted in lives lost‚ both human and animal alike‚ and really brought the issue of off-shore oil drilling to attention. While some may believe that offshore oil drilling may seem like a harmless source of revenue for the United States‚ it is imperative that citizens realize that drilling does more harm than good.

DRILLING FLUIDS The key to making the rotary drilling system work is the ability to circulate a fluid continuously down through the drill pipe‚ out through the bit nozzles and back to the surface. The drilling fluid can be air‚ foam (a combination of air and liquid or a liquid. Liquid drilling fluids are commonly called drilling mud. All drilling fluids‚ especially drilling mud‚ can have a wide range of chemical and physical properties. These properties are specifically designed for
