Features. The standard oil drilling process is conducted by boring a hole between 5 and 36 inches into the earth. A drill string is used, which is a series of tubes put together that continue to dig deeper until oil is found. Derrick - support structure that holds the drilling apparatus; tall enough to allow new sections of drill pipe to be added to the drilling apparatus as drilling progresses. Blowout preventer - high-pressure valves (located under the land rig or on the sea floor) that seal the high-pressure drill lines and relieve pressure when necessary to prevent a blowout (uncontrolled gush of gas or oil to 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. The drilling rig works like an enormous electric hand-drill of which the derrick would be the body, the drill strings the drive and the drilling tool the drill bit. The most usual tool is an Remove the drill and insert casing pipe into the conductor hole. Casing pipe is a long metal tube inserted into the well to the depth at which the oil company believe oil can be found. Fill the space between the rock and casing pipe with cement. This will protect the water table, aquifers, Two main techniques are used to drill oil wells today. In horizontal drilling, the idea is to extract oil that happens to be oriented in a mostly sideways direction in relation to the ground. This is the situation most commonly observed in rock shale because of the way the rock itself forms (it tends to fracture sideways under high pressure). To surmount these obstacles, petroleum companies have invested billions into the development of offshore drilling and offshore oil platforms. The first of these platforms was constructed in 1897 at the end of a wharf in California. In the years to follow, oil prospectors pushed out into the ocean,

Such is the hazardous nature of the oil industry. Offshore drilling (i.e. the process of extracting petroleum from rock formations under the ocean floor) is high-risk at Articles, news, products, blogs and videos covering the Drilling & Production market.

31 Jan 2011 Crude oil is a liquid mixture of hydrocarbons, which are chemical compounds that consist of hydrogen and carbon in varying amounts. By drilling 25 Nov 2009 The “through-tube rotary drilling” method is designed to allow oil companies to drill a new well through the “production tubing” of an older well. In 2008 alone, the United States produced an estimated 4.9 million barrels of crude oil per day and imported 9.8 million barrels per day from other countries [source: U.S. Energy Information Administration]. This oil gets refined into gasoline, kerosene, heating oil and other products. To keep up with our consumption, oil companies must constantly look for new sources of petroleum, as well as improve the production of existing wells.

How to Drill an Oil Well. Drilling an oil well is a massive project that requires multiple teams of workers and very deep pockets. But money and manpower aren't enough. Before beginning, there will be permits and proposals to fill out,

As the drill bit is pushed into the well, drilling fluid or "mud" is pumped through the drill pipe and into the well. The drilling fluid lubricates the drill bit and brings the clippings from the bit back to the surface. Drilling. A drilling rig bores a hole down through the dirt and rock to the oil reservoir. This hole is usually between 5 and 36 inches wide. The drill itself is pushed down by the weight of the heavy metal piping above it, which pumps down drilling fluid called "mud.".
