Abstract:
Methods and systems are provided to enhance recovery of hydrocarbons from a formation by altering wettability at a surface of the formation towards more water-wet. One method includes: providing a formation; providing an aqueous stream for injecting into the formation; adding a reducing agent to the aqueous stream; and injecting the aqueous stream with the reducing agent into the formation to alter a surface charge of the surface of the formation to become more water-wet to enhance recovery of hydrocarbons from the formation. The reducing agent is responsive to characteristics of the formation, characteristics of brine of the formation, and characteristics of hydrocarbons of the formation. Also provided is a method to select a brine composition to be injected into a formation to alter wettability at a surface of the formation towards more water-wet to enhance recovery of hydrocarbons from the formation.

Claim (Index 5):
The method of  claim 3 , wherein the uncertainty analysis comprises Design of Experiments, Karhunen-Loeve transform, Principal Component Analysis (PCA), sensitivity analysis, or any combination thereof
