... at the core outlet changes. It was observed by scanning electron microscope that there were fines on the fracture wall after the experiment. Analysis shows that fine migration is the main reason for the change of permeability under different injection-production pressure modes. gas storage flow...

... Recent experimental studies show that fines migration effect in sandstone rocks is more prominent at higher temperature. However, increased fines migration is generally attributed to temperature dependant zeta potential. In this study, laboratory studies were designed to investigate if mineral...

..., sand retention problem and low proppant coverage. This paper describes the actions to improve robustness of sand control, as well as the implementation of fines migration additives in order to improve the productivity. To date, a database of GP zones has been created. More than 25 new wells and more...

... and porosity of the matrix, can vary widely. Such variable petrophysical and compositional properties of sandstone formations can affect the severity of fines migration and the performance of acid stimulation treatments. To evaluate the effect of acid stimulation on petrophysical properties before and after...

... a critical shear rate, a plugging tendency is observed. This plugging is attributed to a damage mechanism called "bridging adsorption" in which stretched polymer macromolecules form numerous bridges across pore throats. At the same time, causes fine migration issue. In this study, the effects of fines...

... Abstract High formation damage, including that induced by fines migration has been reported in numerous geothermal projects. The attaching electrostatic forces acting on fines are weak at high temperatures if compared with drag and lifting forces, which detach the particles from grain surfaces...

... Abstract Formation damage in oil reservoirs as a result of fines migration is a major reason for productivity decline. Fines loosely attached to the pore surface are in the equilibrium with the pore fluids. These particles start to flow when the equilibrium state is disturbed which, may end up...
