Method of characterizing the flowpath for fluid injected into a subterranean formation
This patent describes a method of characterizing the flowpath for fluid injected into a hydrocarbon-containing subterranean formation surrounding a wellbore for displacing hydrocarbons through the formation. It comprises injecting fluid into the subterranean formation through the wellbore at a pressure below the formation fracturing pressure, wherein the injected fluid is capable of displacing hydrocarbons through the formation and is injected in a volume for displacing the hydrocarbons a sufficient distance from the wellbore to allow the flowpath to be characterized; producing fluids from the formation through the wellbore; and determining percentage of injected fluid in produced fluids for indicating whether the primary flowpath for fluid injected into the formation for displacing hydrocarbons through the formation is rock matrix or natural fractures.
