Abstract
A two-phase fluid is metered by injecting a surfactant into the two-phase fluid, homogenizing the fluid and surfactant with either a porous medium or an orifice plate to form a pseudo-single phase fluid, and metering the pseudo-single phase fluid. In one embodiment, both the injection of surfactant and the homogenization with either a porous medium or an orifice plate occur within one foot of where the pseudo-single phase fluid is metered. In another embodiment, the surfactant is injected at a wellhead and the metering occurs downhole.
