Production casing is the final casing string set in a well and usually reaches from the surface to Target Depth (TD). The type of casing used depends upon the different conditions in the well. Commonly, production casing sizes range from 4 + 1 ⁄ 2 in (110 mm) to as large as 9 + 5 ⁄ 8 in (240 mm). It is the last string cemented in a well ...
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 ...
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).
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 ...
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.
API 6A, 20th Edition, October 2010; Specification for Wellhead and Christmas Tree Equipment; ISO 10423:2009 Wellhead and Christmas Tree Equipment; In general well heads are five nominal ratings of wellheads: 2, 3, 5, 10 and 15 (×1000) psi working pressure. They have an operating temperature range of −50 to +250 degrees Fahrenheit. They are ...
