ABSTRACT:
A method for drilling a plurality of wellbores for producing an oil and/or gas field to the maximum extent with the least number of wellbores wherein at least two longitudinally extending drilling zones are established spaced apart and essentially parallel to one another and drilling alternate longitudinally spaced apart curved wellbores from said drilling zones, each curved wellbore extending toward the producing formation and the opposing drilling zone, each curved wellbore being straightened out and thereafter following a predetermined producing formation until the wellbore reaches the vicinity of the opposing drilling zone. A plurality of the alternating longitudinally spaced wellbores are employed along a pair of drilling zones and a plurality of pairs of drilling zones can be employed. The resulting series of wellbores can be employed to carry out an enhanced oil recovery process by using part of said wellbores as injection wells and part of said wellbores as producing wells.
