“…Considering all the experimental results, it should be emphasized that the core plugging effects observed with several asphaltenic crudes exhibit very similar trends, both in reducing permeability and accumulating in situ deposits with core damage results from the migration of fine-grained solid particles accompanying brine flow through the porous medium [18,19,20].…”

PERMEABILITY DAMAGE DUE TO ASPHALTENE DEPOSITION: EXPERIMENTAL AND MODELING ASPECTSThe flow properties of several asphaltenic crudes were studied at reservoir temperature in rocks of different morphology and mineralogy.The experiments performed showed a progressive reduction in permeability to oil during injection, varying in rate according to the system considered.The existence of organic deposits was verified by ÒRock-EvalÓ pyrolysis measurements made on sections of samples taken at the end of flow at different distances from the entry face. This technique enables the profile of the deposits to be quantified.The interpretation of the permeability damage experiments and their simulation are treated by comparing the asphaltenes in oil to colloidal particles in suspension, capable of being deposited at the surface of the pores and thus reducing the permeability of the porous medium. The first simulations were carried out using the ÒPARISÓ IFP particle damage model, which has recently been Se ha procedido al estudio de las propiedades de circulaci-n de varios crudos asfaltŽnicos a la temperatura del yacimiento de origen en rocas de morfolog'a y mineralog'a de distinta 'ndole.Las experimentaciones llevadas a cabo hacen resaltar una reducci-n progresiva de la permeabilidad al petr-leo durante el transcurso de la inyecci-n, m ‡s o menos r ‡pida segoen los casos.La existencia de sedimentos org ‡nicos se ha verificado mediante mediciones de pir-lisis "Rock-Eval" efectuadas mediante secciones de muestras extra'das al final de la circulaci-n fluida y a distintas distancias de la cara de entrada.

“…In such cases, Rege and Fogler [83] have shown that the higher the overlap between the size distribution of fines and that of pore constrictions, the higher is the extent of plugging and vice versa. Table 3 presents some qualitative results on whether plugging or other possible types of deposition would possibly occur as determined by the ratio of the size of fines to size of the pore constrictions [74,84].…”

“…The above three equations are adopted as the governing equations for the erosion within soils. The eroded soil particles can redeposited during their travel, but the redeposition process is ignored in this study since there is experimental evidence that redeposition can be ignored for small concentrations of soil particles in pore streams typical of natural subsurface systems (Gruesbeck and Collins, 1982;Reddi and Bonala, 1997). From an engineering viewpoint, it has been claimed that a consideration of redeposition may lead to an underestimation of soil erosion, which means that soil structures can be put at risk of deterioration.…”

About 50z of the world's dam failures are triggered by piping, which is a primary cause of embankment breaks. The phenomenon of piping results from the erosion of soil particles and their transport within a soil mass. In this paper, a numerical method is proposed to analyze the erosion within soils and the transport of eroded soil particles by adopting the concept of the erosion rate of soils. In such an analysis, the saturated-unsaturated seepage ‰ow of the pore liquid, the detachment of the soil particles from the soil fabric, and the migration of the eroded particles are taken into consideration, and the equations related to the conservation of the pore liquid and the eroded soil particles are numerically solved. This numerical simulation allows for the procurement of the temporal alteration and the spatial distribution of the porosity, the particle size distribution, and the concentration of the detached soil particles in the pore liquid, as well as the distribution of pore liquid pressure. The results have revealed that the method can reproduce the experimental data from previous studies on the internal erosion of soils and that it qualitatively predicts, from the numerical experiments, the typical development of piping within soils, such as soil blocks and embankments, as the solutions to the initial and the boundary value problems of the governing equations.
