Abstract
A method for evaluating multiple wells using water chemistry analysis may include testing a parameter associated with a first sample obtained from each of the wells over a period of time prior to implementing the field operation of the well. The method may also include generating a baseline of the parameter associated with the first samples for each of the wells. The method may further include testing the parameter associated with second samples obtained from each of the wells during the field operation of the well. The method may also include determining a difference in the parameter between the baseline and results of testing the second samples for at least one of the wells, where the difference exceeds a threshold parameter value for the parameter, and where the difference includes a characterization of water saturation.
