Sentence examples for pulsed injection from inspiring English sources
On the other hand, the advantage of intermittent and pulsed injection of water was apparent.
These were continuous (constant rate), intermittent, and pulsed injection of water.
The differential pressure fluctuated significantly during intermittent and pulsed injection of water (Fig. 10).
(3) During pulsed injection of water, unbalanced formation pressure was caused, and the swept volume was expanded, and consequently the highest oil recovery increment was achieved.
