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 ...
Regularly, for example once a month per well, the flow from one and only one selected well is led into the test separator for determining well flow rate for the selected well. [3] The separator divides the flow from the well into the streams of individual products which typically are oil, gas and water, but may include natural-gas condensate ...
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.
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 ...
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 ...
The well fluids at the wellhead are at high pressure. Production pressures of greater than 23,000 pounds per square inch (1,600 atm) are not uncommon, but typically are lower than this. [ 2 ] The high pressure is reduced at the choke valve to typically 7 to 30 bar at the separator, although the first stage separator could operate at higher ...
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 ...
