1. n. [Production Testing]
A fixed choke or a choke with an adjustable needle, sleeve or plate that can be changed to adjust the flow rate. The flow rate from a well is limited to conserve reservoir energy, decrease friction forces, improve production efficiency, and prevent development of conditions that can reduce ultimate recovery. A high rate of fluid can generate a drastic cooling effect near the wellbore with the precipitation of scales and paraffins as well as a reduction of the oil relative permeability because of an increase in gas saturation.
