Abstract

A method of treating a subsurface formation with low permeability to increase total oil production from the formation is disclosed. The method may include providing a first fluid into two or more fractures emanating from a first wellbore. The first fluid may be provided at a pressure below a fracture pressure of the formation. The first fluid may increase a pressure in zones substantially surrounding a first fracture and a second fracture emanating from the first wellbore. A zone having a lower pressure may be located between these zones. Additional fractures may be formed from a second wellbore in the formation with at least one of the additional fractures emanating from the second wellbore and propagating into the lower pressure zone. Hydrocarbons may be produced from the second wellbore. A second fluid may be provided into the first wellbore before and/or after producing the hydrocarbons from the second wellbore.
