... conducted through CFD techniques to evaluate the effects of various parameters on ECD, particularly useful for planning of MPD wells. Friction pressure losses and cuttings concentration are two crucial components of ECD. A lot of experimental and theoretical research works were performed to study...

... permeability modifier chemistries at various concentrations under different saturation conditions. The RPM was applied into a brine saturated core – to assess its water "shut-off" properties and into an oil saturated core – to assess its formation damage potential. The effectiveness was assessed from comparing...

..., temperature, and acid concentration, the blended stimulation fluid performed very similarly in the presence and absence of the additive in terms of PVBT and Time to BreakThrough (TBT), showing that the stimulation fluid's performance was not hampered by the presence of the additive. However, while post-test...

... both detrital and authigenic particles are detached. The pressure drop across the overall core and the concentration of the fine in the produced fluid have been measured. We have derived equations for authigenic-fines detachment using the beam theory and the von Mises failure criteria to obtain...

... at lower concentrations, the active ingredient reacts with rock minerals. A damaged dolomite core was also treated, and the results showed that the removal of Barite-based scale can be achieved even in the presence of native calcite or dolomite minerals. Also, it is found that wormholing can be only...
