چکیده

Abstract

As  the  demand  for  crude  oil  increases,  the  oil-producing  countries  try  to increase  production.  Enhanced  Oil  Recovery  (EOR)  techniques  play a  significant  role in improving  oil production.  Improved  or  smart  water  injection,  among  the  methods,  has higher  performance  due  to  its  low  cost.  Carbonated  smart  water  is  injected  to  improve smart  water  capabilities.  Dissolution  of  carbon  dioxide  in  water  will  change  chemical properties  of  the  injected  water  to  facilitate  wettability  alteration  from  hydrophobic  to hydrophilic  more  effectively.  Besides,  it  causes  swelling  and  changes  of  oil  density  and viscosity  by  transferring  from  the  aqueous  phase  to  the  oil  phase.  Adding  CO2  to  the smart solution can have other effects, expressed as dissolution and carbonate rock weight alteration, in addition to the wettability alteration on carbonate rock. In this communication, NaCl, KCl, Kl, MgCl2, CaCl2, Na2SO4, MgSO4, and K2SO4 were used to produce smart water, and CO2 gas was utilized to carbonate the water. Observational/visual  and  contact  angle  tests  were  then  carried  out  to  express  wettability alteration of carbonate rock with smart water and carbonated smart water. These observational tests clearly indicate the wettability alteration property of injected materials.  Carbonated  smart  water  exposed  to  rock  analysis  shows  that  Mg2+  ion  was higher in comparison with Ca2+ rate in tested carbonate rock. Therefore, we can say that the rock is a Dolomite one. Finally, by conducting tests on oil production imbibitions, we show that the smart water while utilizing the provided mechanism is capable of improving  the  oil  production  in  contrast  to  imbibitions  with  normal  water,  such  that  the imbibitions with smart water increases the production 33% more in contrast to production with initial formation water.
