A method includes drilling a first, non-vertical wellbore in a first direction. The first wellbore includes a first heel section residing at a first production zone of a subterranean formation and a first toe section downhole of the first heel section and residing at a second production zone of the subterranean formation. The first wellbore defines a first central axis defining a first plane. The method also includes drilling a second, non-vertical wellbore in a second direction opposite the first direction. The second wellbore defines a second central axis defining a second plane substantially parallel to the first plane. The second wellbore includes a second heel section residing at a third production zone opposite the first production zone and a second toe section downhole of the second heel section and residing at a fourth production zone opposite the second production zone to help prevent pressure interference between the wellbores.

Drilling wellbores in a multilayered reservoir

A method for artificially recharging a target reservoir in a geological formation using powered water injection from a local source aquifer in the geological formation. The method comprises detecting chemical properties of water in the source aquifer, determining whether the water in the source aquifer is compatible with water in the target reservoir based on the chemical properties, activating an electrical submersible pump (ESP) positioned between target reservoir and the source aquifer to inject water from the source aquifer into the target reservoir, detecting downhole pressure, temperature and water flow rate conditions at the ESP, and controlling a rate at which the ESP injects water using the downhole pressure, temperature and water flow rate conditions.
