USA Superior Energy Holdings, Inc. has witnessed a 200% plus increase in oil production from an existing oil well during recent testing. This is the result of a successful cyclic Nitrogen test of the Enhanced Oil Recovery (EOR) technology developed by USA Superior.
This testing consisted of injecting a volume of Nitrogen into existing perforations in a well. Prior to this test, the well was producing a small volume of fluids consisting of 5% oil and 95% water. For the first three days after the test, the well pumped 100% oil before the nitrogen pressure depleted, representing a sizeable increase in the oil capable of being produced from the same well.
These tests were conducted to measure and verify potential results USA Superior's research had shown could be expected when using the company's cyclical nitrogen injection EOR program. Cyclical nitrogen injection is where a gas (nitrogen) is injected into existing oil wells to re-pressurize the oil in formation. Within a brief period of time, this reenergized pressure diffuses about the well bore. It then allows the re-pressurized oil to produce back into the well bore. As oil production and pressure diminishes over a period of time, another cycle of nitrogen gas is injected into the well bore thereby re-pressurizing the remaining oil in the formation. These cycles of injection and oil production continue until no longer economic.
"We feel these results show the potential that a cyclic nitrogen injection program implemented across a field can produce," stated Randy Holifield, Field Supervisor of USA Superior Energy Holdings, Inc.
Third party engineering reports estimate that existing wells have only produced 5 to 10% of the oil in the ground from primary production with 90 to 95% of the remains to be produced through secondary and tertiary methods. USA Superior expects a cyclic nitrogen injection program, in addition to horizontal enhancements, to be able to produce an additional 15 to 30% of the oil still left in the ground.
