.... It was reduced to 0.44 mg/gm in the presence of the polyacrylate about 56% reduction. The dynamic coreflood tests showed that retention can be reduced significantly by 50% - 70% in the presence of the sacrificial agent. This reduction in retention enabled quicker pressure stabilization, increasing injectivity...

.... For the 3D field-scale model, the findings showed that temperature reduction from mixing between injected and formation waters triggered H 2 S generation reaction and accumulation at the injector. Subsequently, it was observed that the front was moving till a breakthrough at the injector after almost 5...
