Abstract

The invention is a method of recovering hydrocarbons from an underground formation by employing modified 7 spot well patterns which contain six substantially vertical corner wells forming a substantially hexagonal well pattern and six substantially horizontal wells located within the hexagonal well pattern running between each of the vertical corner wells and the center of the well pattern. Preferably, the modified 7 spot pattern will also contain a substantially vertical central well located relatively near the center of the substantially hexagonal well pattern. Another embodiment contains six substantially vertical corner wells forming a substantially hexagonal well pattern, a substantially vertical central well and six sets of three horizontal wells, each set of three horizontal wells forming a substantially Y-shaped pattern.
