Flowmeter accounts for water entrained in produced oil
During oil-and-gas production, the recovered petroleum product is almost never pure; in most cases, it contains water or gas in some form. With traditional measurement methods, these impurities can lead to inaccurate measurement of net oil from the wells. This company’s patent-pending Complete Net Oil solution encompasses both the net oil-and-gas void fraction functionality. It uses precise mass flow and density measurements from the RotaMass Coriolis meter, which switches seamlessly between the two functions in the same meter with no disruption to production or measurement, says the company. The oil-to-water ratios are determined by combining internal algorithms with API oil density curves and the well’s unique produced-water properties. The Complete Net Oil solution is adapted to each unique well site, and is adjustable as the well changes and the field matures. This reduces inaccurate readings of oil from separators and leads to better realtime net oil measurement usinga single device. It is available with Modbus communication for easy integration with existing control, PLC and Scada systems. — Yokogawa Corp. of America, Sugar Land, Tex.
