What is the difference between well and reservoir?

That block of oil bearing rock is what we call a reservoir. A lot of people use the term reservoir and oilfield interchangeably but both mean a piece of ground containing oil bearing rock. To get the oil out of the rock you must drill a hole down from the surface into the oil bearing rock, That hole is called a well.

What is oil well reservoir?

A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations.

How many oil wells are in Nigeria?

Nigeria has a total of 159 oil fields and 1481 wells in operation according to the Department of Petroleum Resources. The most productive region of the nation is the coastal Niger Delta Basin in the Niger Delta or “South-south” region which encompasses 78 of the 159 oil fields.

What are the different types of oil reservoirs?

Reservoirs can be divided into gas, condensate gas, volatile oil, conventional oil, high pour-point oil, and heavy oil reservoirs in accordance with the properties of reservoir fluids.

What is unconventional reservoir?

An unconventional reservoir consists of an ultra tight source rock, trap and seal containing organic rich matter that has reached thermal maturity without migration.

What comes out of an oil well?

Oil generally comes out of the well mixed with water and, often, small amounts of natural gas. Similarly, natural gas often comes out of the ground mixed with water vapor and other gases. The remaining oil, gas and water mixture goes into a heater/treater unit.

How deep is a Texas oil well?

The average Texas oil well is 900 feet deeper again – but this is quite literally just scratching the surface. Hydraulic fracturing reaches depths ranging from 5,000 feet to 20,000 feet. Now consider the average depth of the ocean – 12,430 feet – and you’re beginning to get an idea of scale.

What is the difference between an oil well and gas well?

Gas and oil well are similar to each other and the name is coined on the basis of fluids produced by them however, while drilling a well in a gas expected zone, one has to keep in mind the high pressure that could be exerted by the gas which is generally, comparatively less in case of oil.

What is an oil field?

An oil field is a tract of land used for extracting petroleum, otherwise known as crude oil, from the ground. Although some contest the exact origin of oil, most consider petroleum a fossil fuel created from dead organic material often found in ancient seabeds thousands of meters below the surface of the earth.

What is conventional oil and how is it obtained?

The term “conventional oil” refers to oil obtained by this method. 2b1 Consulting explains that after these oil fields have been significantly depleted, the well’s natural pressure might drop to where it cannot extract more oil. In this case, water or gas injection can be used.

How is oil extracted from oil fields?

Oil fields are dotted with a variety of extraction equipment which includes drilling rigs, offshore platforms, pump jacks, and more. There may also be exploratory wells probing the edges, pipelines to transport the oil elsewhere, and support facilities.
