Oil and gas extraction systems use pipelines and valves with specific functions for each zone. Among the valves are the so-called choke valves, which adjust the pressure drop so that the flow is optimal. In the present work an adjustable orifice cage and sleeve type valve was studied by means of a computation fluid dynamics. The objective is to obtain the mass flow rate through the valve when the pressure differential is set and compare the result with data from a production report. For the simulation it is assumed that: a) The gas present is negligible; b) The mixture is a single homogeneous fluid whose properties were approximated by historical data from similar wells; c) The flow is stationary. A mass flow result was obtained with a relative error of 9,7%, so the value is considered to be representative of reality.
