Extraction of petroleum in the context of "Oil drilling"

The petroleum industry, also known as the oil industry, includes the global processes of exploration, extraction, refining, transportation (often by oil tankers and pipelines), and marketing of petroleum products. The largest volume products of the industry are fuel oil and gasoline (petrol). Petroleum is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, synthetic fragrances, and plastics. The industry is usually divided into three major components: upstream, midstream, and downstream. Upstream regards exploration and extraction of crude oil, midstream encompasses transportation and storage of it, and downstream concerns refining crude oil into various end products.

Petroleum is vital to many industries, and is necessary for the maintenance of industrial civilization in its current configuration, making it a critical concern for many nations. Oil accounts for a large percentage of the world's energy consumption, ranging from a low of 32% for Europe and Asia, to a high of 53% for the Middle East.

A pollutant or novel entity is a substance or energy introduced into the environment that has undesired effect, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts). Pollutants result in environmental pollution or become of public health concern when they reach a concentration high enough to have significant negative impacts.

A pollutant may cause long- or short-term damage by changing the growth rate of plant or animal species, or by interfering with resources used by humans, human health or wellbeing, or property values. Some pollutants are biodegradable and therefore will not persist in the environment in a long term. However, the degradation products of some pollutants are themselves pollutants such as DDE and DDD produced from the degradation of DDT.

Al Wahat or The Oases (Arabic: الواحات Al Wāḥāt, English: The Oases), occasionally spelt Al Wahad or Al Wahah (English: The Oasis) is one of the districts of Libya. Its capital and largest city is Ajdabiya. The district is home to much of Libya's petroleum extraction economic activity.

BP p.l.c. (formerly The British Petroleum Company p.l.c. and BP Amoco p.l.c.; stylised in all lowercase) is a British multinational oil and gas company headquartered in London, England. It is one of the oil and gas "supermajors" and one of the world's largest companies measured by revenues and profits.

It is a vertically integrated company operating in all areas of the oil and gas industry, including exploration and extraction, refining, distribution and marketing, power generation, and trading.

Enhanced oil recovery (abbreviated EOR), also called tertiary recovery, is the extraction of crude oil from an oil field that cannot be extracted after primary and secondary recovery methods have been completely exhausted. Whereas primary and secondary recovery techniques rely on the pressure differential between the surface and the underground well, enhanced oil recovery functions by altering the physical or chemical properties of the oil itself in order to make it easier to extract. When EOR is used, 30% to 60% or more of a reservoir's oil can be extracted, compared to 20% to 40% using only primary and secondary recovery.

There are four main EOR techniques: carbon dioxide (CO₂) injection, gas injection, thermal EOR, and chemical EOR. More advanced, speculative EOR techniques are sometimes called quaternary recovery. Carbon dioxide injection, known as CO₂-EOR, is the most common method. In this method, CO₂ is injected into a depleted oil field and is mostly left underground.

Rio Grande do Norte (UK: /ˌriːuː ˌɡrændi duː ˈnɔːrti/, US: /- ˌɡrɑːn-/, Portuguese: [ˈʁi.u ˈɡɾɐ̃dʒ(i) du ˈnɔʁtʃi] ) is one of the states of Brazil. It is located in the northeastern region of the country, forming the northeasternmost tip of the South American continent. The name literally translates as "Great Northern River", referring to the mouth of the Potenji River.

The state is divided into 167 municipalities and the capital and largest city is Natal. The state has 410 km (254 mi) of sandy beaches and contains Rocas Atoll, the only atoll in the South Atlantic Ocean. The main economic activity is tourism, followed by the extraction of petroleum (the second largest producer in the country), agriculture, fruit growing and extraction of minerals, including considerable production of seasalt, among other economic activities. The state is home to 1.7% of the Brazilian population and produces 1% of the country's GDP. In 2017, the murder rate rose by 655%, making Rio Grande do Norte the state with the highest murder rate in Brazil: 63.9 per 100,000. But since then, it has experienced a gradual decline, dropping 6 percentage points in 2023 to 21.65.
