| Abstract: | The recent developments in understanding the wettability alteration caused by drilling fluids and related factors and the mechanisms involved are summarized in this review paper.The wettability characterization for reservoir rocks is introduced. The effects of drilling fluids and their chemical additives,inorganic ions,pH values, and pressure on the wettability are analysed.The formation damage due to the wet- tability reversal induced by drilling fluids is discussed,mainly from the correlation of wettability with oil/water permeabilities and with oil recoveries.The approaches and measures to prevent and overcome this kind of formation damage are also prese- nted. |
| Keywords: | Wettability Wettability Reversal Formation Damage Reservoir Rocks Relative Permeability Oil Recovery Drilling Fluid |
