Feasibility Study on Downhole Gas–Liquid Separator Design and Experiment Based on the Phase Isolation Method

Applied Sciences, 2021
As oil exploitation enters its middle and late stages, formation pressure drops, and crude oil degases. In production profile logging, the presence of the gas phase will affect the initial oil–water two-phase flowmeter’s flow measurement results.

Numerical Simulation and Holdup Prediction of Oil-Water Two-Phase in Low Yield Shale Oil Near Horizontal Wells

Cejing jishu
The production of shale oil wells is typically low, and logging instruments such as the flow scanning imager (FSI) may exhibit poor turbine response in low-production wells, leading to measurement deviations and reduced interpretation accuracy.
