Abstract

The different physical and mechanical aspects of the processes leading to the formation damage caused by the movement and the entrapment of the suspended particles and the scale formation were studied. Permeability decline was affected by various parameters, i.e., solid particle concentration, flow rate, and the initial permeability of the porous medium. The high rates of permeability damage occurred under conditions of high concentration of solid particles, small ratio of solid particle size to the mean diameter as well as low flow rates in low permeability porous media. Low permeability porous media were more sensitive to permeability damage caused by solid particles invading pore spaces than high permeability porous media. Solid particles initially present in the porous medium performed an important role when the water is injected into porous media. The phenomena of the invasion of solid particles into a porous medium were simulated by the use of a phenomenological mathematical model. The model was capable of simulating invasion of solid particles through the porous medium. This model could predict the trend of permeability damage due to the invasion of solid particles. The modeling results demonstrated a close agreement with experimental data. The radial model predicted permeability reduction in radial porous media. The injection rate had a significant effect on the permeability reduction. The amount of solid particles that were carried by the injection water into the porous medium was another important factor. This is an abstract of a paper presented at the SPE International Symposium and Exhibition on Formation Damage Control (Lafayette, LA, 2/20-21/2002).
