Abstract
The flowpath for fluid injected into a hydrocarbon-containing subterranean formation for displacing hydrocarbons through the formation is determined by injecting a fluid into the formation through a wellbore, producing fluids from the formation through the wellbore, and measuring the percentage of injected fluid in produced fluids. A percentage of at least about 90% of injected fluid in produced fluids during production of about the first one-third of the total volume of injected fluid indicates that the primary flowpath is rock matrix.
