The Well Innovation's Rotating Control Valve is a hydraulic remotely-controlled rotational valve used for regulating hydrocarbon production, or water injection in reservoirs.
The main advantage of the Rotating Control Valve is a Rotating Sleeve
that incorporates a system of stationary spring-loaded tungsten carbide inlays in an outer sleeve and a rotating solid tungsten carbide inner sleeve providing a metal to metal erosion resistant seal.
The inner sleeve is fitted with holes that line up with the corresponding holes in the inlays, according to the position of the inner sleeve, to provide adjustable flow areas or a closed valve, as required.
The Qualification Test consisted of 200 cycles simulating one operation per month over 15 years. The test cycles, involved operating the valve from fully closed, to fully open, and back to fully closed.
The valve was able to seal after 100 tons of sand had been flowed through at an average flow rate of 16,500 bpd and was also tested as an injection control valve with 90 tons of sand flowed through at a rate of 12,000 bpd.
