Alpha VS/R Wet-Gas Flowmeter Applications & Features

Applications

• Optimize gas and condensate production. The direct measurement of produced hydrocarbon gas and condensate allows for implementation of optimization strategies and monitoring the results in real time. Examples include identifying condensate banking and ultimately improving gas recovery. Weatherford offers a full range of production monitoring equipment, analysis and optimization software, control logic and artificial lift systems. Weatherford has implemented production monitoring and optimization systems on more than 100,000 wells worldwide.
• Production allocation. The flowmeter provides real-time hydrocarbon production data from each well for material balance calculation and allocation.
• Monitor water encroachment. The Alpha VS/R meter yields instantaneous water content measurements and can be used to detect initial water onset. The Red Eye multiphase water-cut meter has been demonstrated to measure water levels down to 0.25 barrels of water per million standard cubic feet of gas.
• Optimize injection of hydrate and corrosion inhibitors. Accurate real-time measurement of water can be used to optimize injection of costly hydrate and corrosion inhibitors. Furthermore, the Alpha VS/R is the only meter that can differentiate methanol (or other common hydrate inhibitors) from water and condensate. This is critical if the measurement is downstream of the hydrate inhibitor injection point.

Features

The Alpha VS/R flowmeter is fully integrated. It maintains a database of all fluid and setup parameters and reports real-time flow rates at line and standard conditions both on the touch panel display and digitally over Modbus®. No additional external equipment is required for operation. The flow computer provides storage of PVT properties of up to 16 wells for installations downstream of a test header or multi-port selector valve. The compact, in-line design is minimally intrusive with low pressure drop and no scheduled maintenance requirements. Pressure taps can be straight through or fitted with remote seals to guard against plugging. The low power consumption and high ambient temperature rating make it suitable for solar panel power and desert applications. It is designed for Class I, Division 1 hazardous locations.
