Patent
·
OSTI ID:5784247
A method of recovering hydrocarbons from an underground formation by employing a modified 5 spot well pattern, which comprises: a substantially vertical central injection well located at approximately at the center of a substantially rectangular modified 5 spot well pattern; and four substantially horizontal production wells, each horizontal well having one end located relatively near the vertical central well and the other end located relatively near each of the four corners of the substantially rectangular well pattern. The wells are perforated so that at least 30 feet of distance exists between perforation intervals of different wells.
