  7. Abstract:
  8. Nowadays, one of the most challenges in drilling and production engineering, is the formation damage caused by fluid filtration while drilling and completion operations. This damage would cause serious problems in pay zone and besides influencing the well performance during its life time – due to permeability reduction in near wellbore area- and cause economic expenses such as workover and stimulation operation. Therefore, considering the aspects of formation damage minimization during drilling and completion operations, the fluid selection for these purposes would be crucial. It requires the knowledge of interactions between these fluids and the reservoir rock. In this thesis, using the Lattice Boltzmann – as one of the noteworthy methods in computational fluid dynamics (CFD) – the movement of solid particles in porous media caused by flow induced forces was simulated. Besides, the permeability reduction in porous media caused by using fluids with solid particles as one of the aspects of formation damage has been investigated
