"This research included a series of experiments, using screen models to evaluate the strength of swollen gel particles. It also includes the study of PPG propagation and extrusion behavior through tubes of various internal diameters. The effect of the particle gel swelling ratio (depending on brine concentration), flow rate; and mesh size on the gel injection pressure and injectivity were studied. The results show that gel injection pressure depends primarily on the swelling ratio and the mesh size. However, the injection pressure does not increase significantly with injection rates, behavior consistent with the real-time injection pressure and injection rate change observed during practical gel treatments in oilfields. It also considered several factors that influence PPG behavior during extrusion and injectivity, including particle gel swelling ratio (brine concentration), and internal diameter of tube through which particle gel is injected. Effect of gel flow resistance factor on the tube internal diameter and the brine concentration of the PPG were also studied. Contrary to common understanding, experiential results have shown that the particle gel flow resistance factor increases as tube diameter increases. Particle gel injectivity decreases as the brine concentration increases and as the tube internal diameter decreases"--Abstract, page iii.
