This report summarizes the final results of a project conducted by Grand Resources, Inc. entitled ?Enhanced Oil Recovery by Horizontal Waterflooding?. This work was conducted over a three-year period beginning in September 2002. The objective of the project was to conduct a field test of a horizontal waterflooding process for the recovery of additional oil from a low permeability shallow Bartlesville sandstone reservoir in northeast Oklahoma. Recovery from conventional primary and secondary recovery operations has been low, leaving a considerable resource available for an improved oil recovery process.
