... Mature Fields face a number of challenges associated with formation damage, such as emulsions, organic deposits, inorganic scales and fines migration. Chemical stimulation has been one of the most used techniques for the removal of formation damage due to good results of past workover jobs...

... and quantify the influence of production parameters on both fines migration and water production. The data obtained during the previous stages were properly combined to generate a comprehensive formation damage model. Nodal system analysis, material balance, reservoir fluids characterization, and mineral...

... Fines migration occurs within the pore network of sandstone formations, thus it is critical to understand what minerals line the ppore spaces of a reservoir rock. Physico-chemical reactions are dominated by fines triggered by their extremely high surface area:volume ratio. For example, Illite has...

... damage which, as proven, is due to fine migration. Flow tests and the mineralogical analysis of some cores from the area have shown that there is a high content of clay particles such as kaolinite and "Mixed Layer" illite, which have a very special characteristic: they move through pores. When...
