Abstract
A method of recovering hydrocarbons from underground formations by employing a modified inverted 5-spot well pattern, which comprises drilling four substantially horizontal wells located along each of the four sides of an inverted 5-spot vertical well pattern, injecting an oil recovery fluid through the central injection well, producing hydrocarbons and other fluids through the vertical corner production wells, ceasing production through the vertical corner wells, and producing hydrocarbons and other fluids through the horizontal wells.
