Abstract
A method and a system for accessing a target fluid in a formation of an oilfield are provided. The method involves acquiring physicochemical property information of a portion of the formation, determining a type and a concentration of a chemical agent based on the physicochemical property information of the portion of the formation, and applying the chemical agent at the portion of the formation to provide a chemical action, where the target fluid is released at the portion of the formation responding to the chemical action.
