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.
It is a cylindrical valve with either a ball or flapper closing mechanism. It is installed in the production tubing and is held in the open position by a high-pressure hydraulic line from surface contained in a 6.35 mm (1/4") control line that is attached to the DHSV's hydraulic chamber and terminated at surface to a hydraulic actuator. The ...
Petroleum engineering is a field of engineering concerned with the activities related to the production of hydrocarbons, which can be either crude oil or natural gas. [1] Exploration and production are deemed to fall within the upstream sector of the oil and gas industry.
A 7 + 5 ⁄ 8 in (190 mm) production casing is set at a depth of about 15,000 ft (4,600 m) and a 5 in (130 mm) production liner set to TD. Probably, this well required a high mud weight at the bottom of the hole and cementing the 7 + 5 ⁄ 8 in (190 mm) casing at TD would have resulted in too much pressure and lost circulation. If lost ...
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 ...
Vessel sizes can be up to 14 to 19 feet (4.27 to 5.79 m) diameter and up to 30 feet (9.14 m) long. Vessels on Gulf of Mexico deepwater installations are 12 to 14 feet (3.66 to 4.27 m) diameter and 60 to 70 feet (4.27 to 21.34 m) long. [4] The number of stages of separation depends on: wellhead pressure; the gas/oil ratio
A production separator is used to separate the produced well fluid from a well, group of wells, or a lease on a daily or continuous basis. Production separators can be vertical, horizontal, or spherical. They can be two-phase or three-phase. Production separators range in size from 12 in. to 15 ft in diameter, with most units ranging from 30 in ...
