The production liner has the same function as a complete string of production casing. A typical casing arrangement in a well is shown in the diagram below. In this case, the surface casing is set to a depth of about 3,000 ft (910 m). Two intermediate strings are set in this well — a 13 + 3 ⁄ 8 in (340 mm) string and a 9 + 7 ⁄ 8 in (250 mm ...
This refers to the portion of the well across the production or injection zone. The well designer has many tools and options available to design the lower completion (downhole completion) according to the conditions of the reservoir. Typically, the lower completion is set across the productive zone using a liner hanger system, which anchors the ...
Drill pipe (#16) is a joint of hollow tubing used to connect the surface equipment to the bottom hole assembly (BHA) and acts as a conduit for the drilling fluid. In the diagram, these are stands of drill pipe which are 2 or 3 joints of drill pipe connected and stood in the derrick vertically, usually to save time while tripping pipe.
Artificial lift is the use of artificial means to increase the flow of liquids, such as crude oil or water, from a production well. Generally this is achieved by the use of a mechanical device inside the well (known as pump or velocity string) or by decreasing the weight of the hydrostatic column by injecting gas into the liquid some distance down the well.
Petroleum production engineering is a subset of petroleum engineering. Petroleum production engineers design and select subsurface equipment to produce oil and gas well fluids . [ 1 ] They often are degreed as petroleum engineers , although they may come from other technical disciplines (e.g., mechanical engineering , chemical engineering ...
For an injection well, the target is selected to locate the point of injection in a permeable zone that may support disposing of water or gas and/or pushing hydrocarbons into nearby production wells. The target (the endpoint of the well) will be matched with a surface location (the starting point of the well), and a trajectory between the two ...
Well stimulation is a broad term used to describe the various techniques and well interventions that can be used to restore or enhance the production of hydrocarbons from an oil well. Hydraulic fracturing (fracking) and acidizing are two of the most common methods for well stimulation.
The right hand valve is often called the flow wing valve or the production wing valve, because it is in the flowpath the hydrocarbons take to production facilities (or the path water or gas will take from production to the well in the case of injection wells). The left hand valve is often called the kill wing valve (KWV).
