Abstract:
Methods of preparing an injection fluid for enhancing hydrocarbon recovery from a formation are described. A divalent salt is added to wastewater to form salinated wastewater. The salinated wastewater is tested for a shift in wettability. The salinated wastewater is tested for a change in oil recovery. The salinated wastewater is applied as an injection fluid. The shift in wettability is equal to or greater than a predetermined wettability differential value, and the change in oil recovery of the salinated wastewater is equal to or greater than a predetermined oil recovery differential value.

Claim (Index 19):
The method of  claim 14 , wherein the predetermined oil recovery differential value ranges between 3% and 5%.
