AbstractThe different mechanisms leading to permeability damages due to particle deposition are analyzed under various situations relevant for oil production. The analysis is based on the relative importance (of the forces involved in the various deposition processes.In this way, different deposition regimes, characterized by the values of a few non-dimensional numbers, are defined. Among the major parameters, some are conventional and usually considered, such as particle and pore sizes, flow rate, particle concentration and suspending fluid viscosity.However, other parameters, which are often ignored, such as particle and pore shape and roughness, particle-particle and particle-pore wall interaction energies as well as pore surface physiochemical heterogeneity play an even more important role. In all cases, the regime determines deposition kinetics and the location~'here particles are deposited inside porous structure. As a consequence, determining both the deposition regime and the mechanism of permeability damage involved are prerequisites before any attempt to model and to predict permeability reduction. Due to the complexity of practical cases, experiments must be carried out to define the regime and the values of the major References and illustrations at end of paper parameters used as input in a suitable formation damage model.Comparisons between model predictions and experimental results obtained under well-controlled conditions show the cases where presently the permeability damage modeling is reliable.

Pore-Scale Investigation of Micron-Size Polyacrylamide Elastic Microspheres (MPEMs) Transport and Retention in Saturated Porous Media

“…The main forces acting on these MPEMs include the driving force of fluid ( F df ) and supportive force of pore-throat walls ( F s ), as shown in SI Figure S7. Increasing the MPEM particle size, MPEM concentration, and fluid velocity and the smaller elasticity are related to increased plugging. , This plugging mechanism is similar to the Jamin effect of bubbles. The similarity lies in the fact that they both can produce an additional flow resistance.…”

Effects of Fines Migration on Well Productivity During Steady State Production

“…From Eq. (11) it follows that the form of Darcy's law for oil flux under the presence of connate water accounts for the permeability damage due to the attached and strained particles (Nabzar et al, 1996;Chauveteau et al, 1998;Mojarad and Settari, 2007;Rousseau et al, 2008)…”

Asphaltene Deposition Preference and Permeability Reduction Mechanisms in Oil Reservoirs: Evidence from Combining X-ray Microtomography with Fluorescence Microscopy

“…Table lists the major existing permeability reduction models due to asphaltene deposition. The earlier correlations suggested between permeability and time, flow rate, flooding agent volume, or asphaltene saturation were based on empirical or ideal models − and verified primarily by core flooding experiments. Minssieux performed flooding experiments on several types of porous media using crudes with asphaltene contents from 0.1 to 6% and measured the quantities of the asphaltene via RockEval analyses.…”
