Sentence examples for swept zone from inspiring English sources
The primary focus is to quantify the oil entrapment behind the swept zone and investigate the pore-level steam propagation and chamber growth.
All these require in-depth analysis of the problem at the pore scale to account for the residual oil saturation (Sor) in the swept zone.
The simulated oil entrapment behind the swept zone as well as the temperature distribution throughout the medium are in good agreement with the experimental datasets.
The modelling showed that permeability decline in the water swept zone, caused by the alteration of the injected water composition and induced fines migration, may be able to improve waterflood performance by delaying water breakthrough and reducing the water cut.
Other studies revealed an even higher avoidance rate during nights due to a flight altitude well above the rotor swept zone (Reichenbach and Grünkorn 2011).
Many authors stated that adverse weather conditions can lead to a decrease in flight altitude of migrating birds, causing them to enter the rotor swept zone (e.g., Aumüller et al. 2011; Coppack et al. 2011; Hüppop et al. 2006).
The residual oil saturations in gas swept zones have been found to be quite low.
It is injected to reduce thief zone permeability and then divert displacing fluid into poorly swept zones.
Composed of one surfactant, a traditional foaming agent generates stable foam with gas or air to block high-permeable swept zones and to improve the sweeping efficiency without significantly improving displacement efficiency.
Mobilization and re-capturing of the reservoir fines may give rise to reduction of the permeability in water swept zones, which subsequently leads to the diversion of water flow from the initially more permeable layers to the less permeable ones.
In the experiments of three parallel sand packs, the HSF foam generated with surfactant GINF-1/air could block the large pores and improve sweeping efficiency, and the ULT foam generated with surfactant LINF-2/air could improve the displacement efficiency in swept zones after water flooding.
