ABSTRACT:
The invention is a method of recovering hydrocarbons from an underground formation by employing a modified 5 spot or 9 spot well pattern which contains a substantially vertical central well and four substantially horizontal wells, each having one end located relatively near the center of a substantially rectangular well pattern and the other ends located relatively near each of the corners of the well pattern. Preferably, the well pattern will also contain four substantially vertical corner wells located approximately at the four corners of the substantially rectangular modified 5 spot or 9 spot well pattern.
