Paper presented at the SPE Asia Pacific Oil and Gas Conference and Exhibition, October 23–25, 2018
Paper Number: SPE-192074-MS
...Introduction Abstract Numerical stability and precision are required when using simulations to predict Enhanced Oil Recovery processes and these can be difficult to achieve for Low Salinity Water Flooding (LSWF). In this paper we investigate the conditions that lead to numerical...

... is 30, the minimum flow measurement is 0.5m 3 /day, and measurement precision is 3%. The advantages of the swing-rod flowmeter include: high working pressure, low power consumption, compact structure, wide measurement range, convenient range adjustment and strong anti-interference ability. The Swing-rod...
