MULTI-PHASE CHARACTERIZATION USING DATA FUSION FROM MULTIVARIATE SENSORS

摘要

A method for determining a wellbore fluid phase includes receiving, from a first sensor, first fluid data (302, 304, 306) for a fluid flowing through a wellbore. The method also includes receiving, from a second sensor, second fluid data (310, 312, 314) for the fluid. The method further includes determining, based at least in part on the first fluid data (304, 306, 308), a first fluid property (1206). The method also includes determining, based at least in part on the second fluid data (310, 312, 314), a second fluid property (1208). The method further includes determining a relationship between the first fluid property and the second fluid property, the relationship based at least in part on respective evaluations of the first fluid property with respect to a first threshold and the second fluid property with respect to a second threshold (1210, 1212). The method includes determining, based at least in part on the relationship, a phase of the fluid (1214).
