Reasons for internal and external valve damage are varied in the industry. Valve damage can occur due to irregular preventive maintenance, sand erosion, internal and external corrosion, improper materials selection, and/or due to operating the valve outside of its operating pressure and temperature ranges1. This paper will focus only on valve cavitation related damage, which happens on water choke valves. The main purpose of this paper is to demonstrate a trial installation of multistage choke valve technology in water lines that reduces high pressure drops across water injection choke valves. The trial test was conducted on two single-stage choke valves installed upstream of two water injection wellheads, which were completed in two different reservoirs. The selected single-stage choke valves were experiencing high noise and vibration levels where operators could barely meet the required water injection rate for each well. Different surface mitigation measures were evaluated to overcome this serious issue prior to conducting the trial installation of the multistage chokes. The field water injection system was studied from the water injection plant (WIP) where the water injection centrifugal pump (3000 psig) is located, through the water lines, fittings and valves all the way to the water injection wellheads. Results from the trial test show that implementing multistage choke valve technology can prevent high noise and vibration levels and allow the target water injection rate per well to be met.
