Oil industry in the context of "Extraction of petroleum"

A sucker rod is a steel rod, typically measuring between 7 and 9 metres (25 and 30 ft) in length, with threaded ends at both sides. It is used in the oil industry to connect the surface components with the downhole components of a reciprocating piston pump in an oil well. The pumpjack, which is the visible above-ground drive for the well pump, is linked to the downhole pump at the base of the well through a series of interconnected sucker rods. Sucker rods are also available in fiberglass, typically manufactured in lengths of 37 1/2 feet and diameters of 3/4, 7/8, 1, and 1 1/4 inch. These rods feature metallic threaded ends, female on one side and male on the other.

The surface unit transfers energy from the prime-mover to the sucker rod string to facilitate well pumping. It achieves this by converting the rotary motion of the prime-mover into the reciprocating motion required by the sucker rod and reducing the prime-mover's speed to a suitable pumping rate. Speed reduction is managed through a gear reducer, while the rotary motion of the crankshaft is transformed into oscillatory motion using a walking beam. The crank arm connects to the walking beam via a pitman arm. The walking beam is supported by a Samson post and saddle bearing. The horse head and bridle ensure vertical pull on the sucker rod string at all times, preventing bearing movement above the stuffing box. A combination of the polished rod and stuffing box is employed to maintain an effective liquid seal at the surface.

Awjila (Arabic: أوجلة, Italian: Augila) is an oasis town in the Al Wahat District in the Cyrenaica region of northeastern Libya. Since classical times it has been known as a place where high quality dates are farmed. Since the Arab conquest in the 7th century, Islam has played an important role in the community. The oasis is located on the east-west caravan route between Egypt and Tripoli, Libya, and the north-south route between Benghazi and the Sahel between Lake Chad and Darfur. In the past, it was an important trading center. The people cultivate small gardens using water from deep wells. Recently, the oil industry has become an increasingly important source of employment.

Al Khor (Arabic: الخور, romanised: Al Khawr) is a coastal city in northeast Qatar, located 50 kilometres (31 mi) north of the capital Doha. Considered one of Qatar's largest cities, it is the capital city of the municipality of Al Khor and Al Thakhira. Dating back to the 18th century, it is one of Qatar's oldest settlements. The name of the city, meaning creek in Arabic, emerged because the original settlement was built on a creek. Until the mid-1900s, it was known as Khor Al Shaqiq.

Originally a fishing and pearling village, much of Al Khor's recent growth has been due to its proximity to Qatar's northern oil and natural gas fields and to Ras Laffan Industrial City. Along with the neighbouring Al Khor Community, it hosts a large number of oil workers. Al Khor Island, an important archaeological and tourist site, is northeast of the city. It was also the venue for the opening game of the 2022 FIFA World Cup.

The petroleum industry in Azerbaijan produced about 33 million tonnes of oil and 35 billion cubic meters of gas in 2022. Azerbaijan is one of the birthplaces of the oil industry.

The State Oil Company of the Republic of Azerbaijan (SOCAR), a fully state-owned national oil and gas company headquartered in Baku, is a major source of income for the Azerbaijani government. The company is run opaquely through complex webs of contracts and middlemen, which non-government watchdog organizations say have channeled revenues to the country's ruling elites.

Produced water is a term used in the oil industry or geothermal industry to describe water that is produced as a byproduct during the extraction of oil and natural gas, or used as a medium for heat extraction. Water that is produced along with the hydrocarbons is generally brackish and saline in nature. Oil and gas reservoirs often have water as well as hydrocarbons, sometimes in a zone that lies under the hydrocarbons, and sometimes in the same zone with the oil and gas. In geothermal plants, the produced water is usually hot. It contains steam with dissolved solutes and gases, providing important information on the geological, chemical, and hydrological characteristics of geothermal systems.Oil wells sometimes produce large volumes of water with the oil, while gas wells tend to produce water in smaller proportions.

As an oilfield becomes old, its natural drive to produce hydrocarbons decreases leading to decline in production. To achieve maximum oil recovery, waterflooding is often implemented, in which water is injected into the reservoirs to help force the oil to the production wells. In offshore areas, sea water is used. In onshore installations, the injected water is obtained from rivers, treated produced water, or underground. Injected water is treated with many chemicals to make it suitable for injection. The injected water eventually reaches the production wells, and so in the later stages of water flooding, the produced water's proportion ("cut") of the total production increases.
