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.

Enhanced secondary recovery of oil and gas in tight hydrocarbon reservoirs

A method for creating a drainage network in a subsurface rock formation includes drilling a first plurality of wellbores extending laterally in a first direction. Each wellbore includes a main portion and an extension portion extending therefrom. A second plurality of wellbores is drilled laterally in a second direction substantially opposed to the first direction. Each of the second plurality of wellbores includes a main portion and an extension portion extending therefrom. The extension portions of the first plurality of wellbores are disposed adjacent main portions of the second plurality of wellbores. The extension portions of the second plurality of wellbores are disposed adjacent main portions of the first plurality of wellbores. Each main portion is hydraulically isolated from each associated extension portion. Each main portion of each of the first and second plurality of wellbores is stimulated.

Method for increasing fluid recovery from multiple lateral wellbores drilled through a subsurface formation

A method for drilling and completing multiple wellbores in a subsurface rock formation includes drilling a first wellbore along a first selected trajectory through the rock formation. The first wellbore is fracture treated and then abandoned. A second wellbore is drilled along a second selected trajectory through the rock formation. The second trajectory is laterally spaced from the first trajectory. The second wellbore is then fracture treated and abandoned. A third wellbore is drilled along a third selected trajectory through the rock formation. The third trajectory is disposed between the first and second trajectories. The third wellbore is fractured treated such that a fracture network extending therefrom hydraulically connects to fracture networks extending from the first and second wellbores.
