DOWNHOLE FLOWMETER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18628906 titled 'DOWNHOLE FLOWMETER
The abstract describes an intelligent completion module with a flowmeter using electromagnetic acoustic transducer (EMAT) sensors and a flow control valve to measure flow rate and speed of sound in production fluid for reservoir management decisions. The flowmeter includes at least two EMAT rings with sensors in circular distribution for propagation or pulse-echo modes, with a single EMAT sensor in pulse-echo mode used for measuring holdups in segregated flow regimes.

Original Abstract Submitted
An intelligent completion module includes a flowmeter that uses one or more electromagnetic acoustic transducer (EMAT) sensors and a flow control valve. The flow rate and the speed of sound in the production fluid from a production zone is measured and used to make reservoir management decisions. The flowmeter includes at least two EMAT rings, including one or more EMAT sensors in a circular distribution which can be used in propagation or pulse-echo modes. In a segregated flow regime, a single EMAT sensor in pulse-echo mode is used to measure holdups of fluid components.
