In the petroleum industry, a field is a large area of land where coal, oil, or gas is found. Three conditions must be present for oil reservoirs to form: a source rock rich in hydrocarbon material buried deep enough for subterranean heat to cook it into oil; a porous and permeable reservoir rock for it to accumulate in; and a cap rock (seal) or other mechanism that prevents it from escaping to the surface. Within these reservoirs, fluids will typically organize themselves like a three-layer cake with a layer of water below the oil layer and a layer of gas above it, although the different layers vary in size between reservoirs.

The typical oil field resembles a small self-contained city in the midst of a landscape with many drilling rigs and/or the pump jacks known as "nodding donkeys" because of their bobbing arm. More than 40,000 oil fields are scattered around the globe – on land and offshore. The largest are the Ghawar Field in Saudi Arabia and the Burgan Field in Kuwait, with more than 60 billion barrels estimated in each.

Development of a field includes the location, drilling, completion, and equipment of wells necessary to produce the commercially recoverable oil and gas in the field.

Oil and gas production necessarily are intimately related. However, the naturally occurring hydrocarbons of petroleum are not only liquid and gaseous but may even be found in a solid state, such as asphaltite.

Where gas is produced without oil, the production problems are simplified because the product flows naturally throughout the life of the well and does not have to be lifted to the surface. However, there are sometimes problems of water accumulations in gas wells, and it is necessary to pump the water from the wells to maintain maximum, or economical, gas production. The line of demarcation between oil wells and gas wells is not definitely established. Most gas wells produce quantities of condensable vapours, such as propane and butane that may be liquefied and marketed for fuel. The more stable liquids produced with gas can be utilized as natural gasoline.

The common methods of producing oil wells are (1) natural flow; (2) pumping with sucker rods; (3) gas lift; (4) hydraulic subsurface pumps; (5) electrically driven centrifugal well pumps; and (6) swabbing.

However, most wells are not self-flowing and various lifting methods must be employed. Approximately 90% of the wells made to produce by some artificial lift method in the United States are equipped with sucker-rod-type pumps. In these the pump is installed at the lower end of the tubing string and is actuated by a string of sucker rods extending from the surface to the subsurface pump. The two common variations are mechanical and hydraulic long-stroke pumping units. Other lifting mechanisms are the gas lift, hydraulic subsurface pumps, swabs, bailers and jet pumps.
