My question is what is the best choice of of type of water if we want to inject water to enhance the recovery, fresh water or salt water
Also I have another question,
If we decided to inject salt water in resrvoir is that will increase the salinity of aquifer ?
If so then is that will increase the salinity of prodeuced water with oil and hence it will increase the procedure for desalting process
since the concentration of salt in remaining water in oil will increase
Thank you .
