Abstract
A method for enhanced hydrocarbon recovery from a subsurface formation includes drilling and completing a plurality of laterally spaced apart wells through the formation so as to enable interference between adjacent ones of the plurality of wellbores. Fluid comprising surfactant is injected into the formation through at least one of the wellbores after an end of primary recovery from selected ones of the plurality of wellbores to initiate secondary recovery of hydrocarbons from the formation.
