DENVER -- WellDynamics has unveiled its HS interval control valve (HS-ICV), which is debris-tolerant and designed for high-pressure, deepwater environments characterized as severe operating conditions. According to the company, the HS-ICV enables deployment of SmartWell systems in more extreme environments.
The HS-ICVs flow trim ensures complete metal-to-metal seal integrity when exposed to heavy wellbore debris. A one-piece valve mandrel design eliminates the potential for wellbore debris to be trapped inside the tool and consequently prevent valve movement. The metal-to-metal flank seal also enables the valve to unload at a maximum differential pressure of 5,000 pounds per square inch (psi) and has been rigorously tested for seal integrity at both low and high-pressure differentials of up to 10,000 psi.
The valve can be used either in simple intervention avoidance applications or in more versatile advanced reservoir management choking applications. For the choking application, the HS-ICV can be accurately positioned using WellDynamics Accu-Pulse incremental positioning module; alternatively, in dry tree applications, it can be positioned using WellDynamics surface positioning technology. In either application, optional onboard position sensors track and provide real-time confirmation of the movement of the flow trim.
