Abstract
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.
