Water Injection Valve Characterisation

Red Spider Technology supplies the oil and gas industry with a range of down-hole products including seawater injection valves. In an initial study, Wilde CFD established an efficient valve characterisation methodology subsequently used to characterise a range of valve sizes.

The analyses were conducted using modules of ANSYS Workbench v11.0. Post-processing identified the fluid force on the poppet and hence fully open flow rate. The actual valve assembly comprises Red Spider’s valve, a lock of third party supply hence unknown geometry and a crossover piece. CFD gave the head loss associated with the valve: guidance was given on the estimation of pressure drop across the whole assembly.
