... of the formation. Because of the problems of permeability anisotropy and permeability contrast of low and high permeable zones, most of displacing agents are injected into the high permeable zone. When the displacing agent is produced from production well, the displacing efficiency is extremely ineffective...

... zones, the invasion is progressing heterogeneously while drilling and acidizing; for less permeable zones, the invasion caused by drilling might not be completely overtaken by acid stimulation. The study demonstrates the importance of drilling and well completion duration in invasion progress across...
