... Abstract The work comprises the set of lab corefloods of the displacement of water by CO 2 from sandstone cores. Previous experimental studies investigated the effects of water evaporation, Rock Dry-out, viscous fingering and Fines Migration with respect to permeability damage during CO 2...

... will migrate into others, either by accident or design. Injection into saline aquifers outside of structural traps, where residual trapping may be dominant and uncertainties about plume migration are greater, may be especially prone to migration across boundaries. If CO 2 being injected into one licence...

... ). Abstract Short-term gas migration during the cementing process has been a challenge in the oil and gas industry. During the curing process, the cement slurry will slowly lose its hydrostatic pressure allowing gas from the formation to enter the annulus. The ideal cement should generate gel structure...

... Shallow gas has been one of the major challenges in petroleum exploration and production during the well construction process. The issue of shallow gas migration through cement was initially raised in the 1960s during the cementing of gas storage wells ( Tinsley et al., 1980 ). Since then, many...

...-cycle migration Introduction Significant concentration of CO 2 in some part of the prolific basins off the coast of Sarawak, offshore Malaysia is being regarded as one of major challenges (even showstopper) for field development, current production, as well as future exploration projects. High...

... Abstract In common practice, gravel pack completion is beneficial as sand control in a typical unconsolidated sandstone reservoir. However, with poorly sorted sand grains, fines migrate and deposit at the gravel-pack matrix, causing permeability reduction and hence, decreasing well productivity...

... Abstract High heterogeneity and small pore throat characterize the mineral compositions of complex reservoirs. The evaluation of the effectiveness of reservoir space, the detailed evaluation of the rock structure, and the evaluation of fluid occurrence and migration all determine...

...) is a phenomenological function in the model, which can be determined from the inverse-problem solution using the fines-migration test data. However, it can be estimated using a simplified geometry of porous space, by torque balance of attaching and detaching forces exerting on the particles attached to the rock surface...

... Abstract During the last two decades, low salinity waterflooding as a part of more general varying water composition has become a promising EOR method. Nevertheless, the physics mechanisms of extra oil recovery by low salinity waterflood are not clearly understood. Yet, fines migration...

... in the slug mode allows drawing the following conclusions: Induced formation damage by low salinity water injection with consequent fines migration has two competitive effects on oil recovery from heterogeneous reservoirs, it diverts injected water into unwept area resulting in sweep enhancement...

... The 3D mathematical model for fines-assisted waterflooding has been presented by Zeinijahromi et al. (2013) . The main assumptions are the mobilization of fines by low-salinity water due to the weakening of electrostatic forces between the particles and the rock, the migration of fine particles...

In petroleum industry the more important is permeability reduction, so the data on pressure drop measurements during fines migration are available. Therefore, in the present paper...

... Abstract A new mathematical model for flow towards the well during water production from geothermal reservoirs accounting for fines mobilization, migration and clogging of production well is developed. Treatment of the well discharge data from geothermal reservoir A (Australia) exhibits good...

... Abstract Migration of fine particulates and/or scale formation is known to plug up etched channels or pore spaces in proppant packs, causing production decline in wells that have been acidized or completed with high-rate water packs or frac-packs. The removal of such damage caused by plugging...
