Inter-particle and molecular forces are of most important forces\r<br />affecting fines migration. Investigating the impact of these types of forces\r<br />requires information about electrical properties of constitutive component and\r<br />Nano-sized solids. Surface potential is a well-known parameter, which can be\r<br />used to measure aforementioned forces. The force balance among electrical,\r<br />gravity, drag and buoyance forces tracing on a particle can be estimated using\r<br />fluid properties and physical properties of reservoir such as surface\r<br />potential, pore size distribution and fine size distribution. The task is to\r<br />set these forces at conditions that fine migration does not take place. This\r<br />paper investigates the impact of several parameters that could influence\r<br />pertinent forces. Effect of ionic strength of flowing fluid is taken into\r<br />account to evaluate Debye length that determines double layer forces. The\r<br />impact of injection rate on a parameter named erosion number is also studied. The results of this study show that how introducing salts and\r<br />injection rate can affect stability of fines on their locations.
