what is a choke in petroleum engineering Choke valves are flow control devices mainly used in oil and gas industries during production of crude oil from an oil well These valves typically control
A device incorporating an orifice that is used to control fluid flow rate or downstream system pressure Chokes are available in several configurations for both fixed and adjustable modes In internal combustion engines with carburetors a choke valve or choke modifies the air pressure in the intake manifold thereby altering the air fuel ratio entering the engine Choke valves are generally used in naturally aspirated engines to supply a richer fuel mixture when starting the engine Most choke valves in engines are butterfly valves mounted upstream of the carburetor jet to produce a higher partial vacuum which increases the fuel draw

A choke holds a back pressure on the well fluids controlling the expansion rate of the gas It is useful for optimizing natural gas lift in oil wells with sufficient gas to flow naturally or in some Petroleum Production Engineering A Computer Assisted Approach By AM Ghalambor Chapter 5 Choke Performance 5 1 Introduction Wellhead chokes are used to limit production rates for
Placing a choke at the wellhead means fixing the wellhead pressure and thus the flowing bottom hole pressure and production rate For a given wellhead pressure by calculating A choke valve is a type of flow control valve that is used to regulate the flow of fluids such as gases or liquids in a pipeline Choke valves are typically used in the oil and gas industry to control the flow of well fluids such

The real essence of modelling choke performance is to give petroleum engineers the latitude to optimise the field operating conditions and predict the oil and gas flow rates that In this paper by using basic concepts of fluid mechanics it is shown that the rate of two phase flow through a choke generally depends on the pressure drop across the choke besides other factors by deriving a global
Wellhead chokes are used to limit production rates for regulations protect surface equipment from slugging avoid sand problems due to high drawdown and control A wellhead choke controls the surface pressure and production rate from a flowing well Chokes usually are selected so that fluctuations in the line pressure downstream of the choke have no
