Patent ID: 11860149
Assignee: SAUDI ARABIAN OIL COMPANY
Field: Measurement (Instruments)
Classification: CPC E  G | IPC E  G

Claim 2:
3. The system of claim 1, wherein in response to determining to utilize the direct approach the logic causes the system to perform at least the following:
calculate a change in pressure from potential energy (ΔpPE) as follows: ΔpPE=pdownstream−pupstream−ΔpF−ΔpKE, wherein pdownstream refers to pressure at a downstream portion of the pipe, wherein pupstream refers to pressure at an upstream portion of the pipe, wherein ΔpF refers to the change in pressure resulting from friction, wherein ΔpKE refers to a change in pressure resulting from kinetic energy; and
estimate water-cut from the following equation: ΔpPE=(1−WC)gohTVD+WC gwhTVD, wherein go refers to a gravity of oil, wherein gw refers to a gravity of water, wherein hTVD refers to a total vertical depth difference between measurements.
