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 form additional fractures in the formation. The first fluid may also increase a minimum horizontal stress in zones substantially surrounding the fractures emanating from the first wellbore and the additional fractures formed. A zone having a lower minimum horizontal stress 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 minimum horizontal stress zone. Hydrocarbons may be produced from the first wellbore and/or the second wellbore. A second fluid may be provided into the first wellbore after producing the hydrocarbons from the first wellbore.
