Flow of oil and gas through chokes

Deportment of Chemical Engineering, University of Kuwait

 

ABSTRACT

 

A theoretical technique for the two-phase flow of oil and gas through wellhead chokes has been developed. This technique assumes non-critical and critical flow conditions through a knife edge orifice where the mass flow rate through the choke reaches a definite maximum as the downstream pressure is further reduced. The paper also investigates the pressure differential ranges where critical velocity or the maximum flow rates is attained. The technique is verified by actual measured field data obtained in oilfield operation. The purpose of this paper is to demonstrate the technique since it is believed that it will be of se to engineers in the field of oil and gas production in which measuring techniques are so difficult and expensive to carry out. It will be shown in the paper that the method is reliable and easy to apply.
