Flow measurement is perhaps of greater importance to the oil and gas industry than it is to any other industry and a good understanding of the metering process remains central to the efficient production of hydrocarbons. For example, interwell allocation, custody transfer, gas flaring and produced water discharge all require metering. The reasons for flow measurement vary from quality control, revenue calculation to environmental regulation. The required accuracy of flow measurement varies with application from better than 1% for fiscal metering, up to 10% for environmental regulation.
The diverse applications within the oil and gas industry call for a wide range of metering technologies with Coriolis mass, ultrasonic and turbine meters finding widespread application. Production plant presents a complex environment for flow measurement, platform space will always be at a premium and many meters are installed in situations that are far from ideal.
Typical oil & gas applications include: fluid loss and leak detection; process gas flow; cooling water flow monitoring; hydraulic fluid flow sensing in blow-out prevention; fiscal or custody transfer metering; measuring produced water discharge.
