Completion The process by which a finished well is either sealed off or prepared for production. Condensate A liquid mixture of pentane and heavier hydrocarbons that is recoverable from a gas well through a separation system. Crude oil A mixture of hydrocarbons that existed in the liquid phase in natural under ground reservoirs and remains liquid at atmospheric pressure after passing through

Clean up of Crude Oil-Contaminated Soil This method is a relatively simple physical process of cleaning up crude oil contaminated soils. SVE involves the use of a specially designed system to remove volatile conta-minants (e.g. crude oil) from the soil in vapour form (Kosky and Jones 1995). The process of SVE is carried out by applying a vacu-um through a system of underground wells which
PRODUCTION OF CRUDE OIL-DRILLING PROCESS . ABSTRACT. The tremendous (large) demand of some petroleum fractions in our modern world today has drive some professionals (experts) in oil sectors into exploration and drilling operation which is aimed at locating the mineral oil deposit and extracting it from beneath the earth surface with aid of
Oil drilling sites can either be developed onshore, i.e., on land, or offshore, i.e., on the ocean floor, depending on the presence of crude oil beneath. Gas oozes, oil seeps, and crater formations as a result of gas leak are the most obvious signs of presence of oil in a particular region. Many factors come into play in the process of identification of a potentially attractive site for oil
crude oil production has been rapidly increasing in the past few years, partly due to favorable geology and the ease of leasing, rising by 3.0 million barrels per day (mbd) between FY2010 and FY2014, causing the federal share of total U.S. crude oil production to fall from 36.4% to 21.4%.
Drilling a well to extract crude oil is a complicated process, but it is the only way to confirm the extent and existence of the oil beneath the earth crust. After initial exploration in activities sites preparation begins. The type of rig system to be used whether rotary or cable, is determined when the drilled well is completed and turned into a production facility. Capable of bringing a
In 2005 the Oil & Gas sector included 498,454 oil wells and 398,161 gas wells in operation. The sector employed 1,381 rotary rigs for drilling new wells.4 The United States is the world’s third-largest petroleum producer and second-largest natural gas producer.5 When crude oil, associated natural gas, and formation water arrive at the wellhead, operators must separate them before further
Crude oil is formed when large quantities of dead organisms are buried underneath sedimentary rock and undergo intense heat and pressure. Petroleum is recovered mostly through oil drilling.
Heavy crude oil cannot be extracted through standard drilling mechanisms. A number of different strategies including the use of steam and chemicals have been devised to make heavy crude oil more liquid and thus more amenable to pumping.
– Crude oil is one of the cheapest liquids on the planet – This is the problem when you want to talk about alternative fuels – Energy independence = if we grow enough corn, make enough ethanol,
Shale oil involves both vertically and horizontally drilling processes whilst crude oil through only vertically drilling process. Horizontal drilling is a drilling process in which the well is turned horizontally at depth.
OIL DRILLING. INTRODUCTION In January 2001 alone, the United States produced an estimated 181 million barrels of crude oil and imported 273 million barrels from other countries.
Upstream activities involve exploring for crude oil deposits and the production of crude oil. Examples of firms that would belong in the upstream segment of the industry include companies that own rights to drill for oil (e.g., ExxonMobil) and companies that provide support services to the drilling segment of the industry (e.g. Halliburton).
The process begins by drilling to the bottom of a fresh water aquifer The drill is then retracted and pulls the loose rocks and sediment to the surface to be discarded (i.e., drilling muds). Surface casing (steel piping) is inserted into the bore hole to protect freshwater aquifers by creating a physical barrier between the aquifer and drilling materials.

APPLICATIONS OF NANOTECHNOLOGY IN OIL AND GAS
Emulsions of crude oil and water can be encountered at many stages during drilling, producing, transporting and processing of crude oils and in many locations such as in hydrocarbon reservoirs, well bores, surface facilities, transportation systems and refineries
In searching for oil and gas, exploratory drilling usually results in “dry” wellsthat are plugged and abandoned. When an oil or gas reservoir is discov- ered, development wells arethen drilled to extract the oil orgas. More than 70,000 exploration and development wellswere drilled annually in the mid-1980s, although drillingactivity decreased sharply in 1986 and has remained depressed (99

The extraction process for oil sands is quite different from drilling due to the high viscosity of this extra-heavy oil. Rather than using drills, crude oil is extracted from oil sands through
Crude oil production on federal lands, particularly offshore, is likely to continue to make a significant contribution to the U.S energy supply picture and could remain consistently higher than previous decades depending on the level of total U.S. crude oil production.
Nanotechnology can be used to improve the drilling process and oil and gas production by making it easier to separate oil and gas in the reservoir. Nanotechnology can make the industry
Extracting crude oil normally starts with drilling wells into an underground reservoir. When an oil well has been tapped, a geologist (known on the rig as the “mudlogger”) will note its presence.
