Kirk Walton Limbach: Downhole upgrading of oils. Philip H Von Neida, March 18, 2004: US20040050547-A1

Oils present in oil reservoirs can be upgraded by high temperature cracking through the injection of oxygen into the reservoir and combusting the oils to generate heat. By employing injection wells and production wells, the oxygen may be placed into the reservoir increasing the flux of oxygen presen ...

Ramakrishnan Ramachandran, Kirk Walton Limbach, Shuen Cheng Hwang: Enhanced oil recovery. Philip H Von Neida, February 27, 2003: US20030037928-A1

A method for enhancing the recovery of oil from underground formations is disclosed. A gas mixture which contains greater than 50% by volume carbon dioxide, the remainder being an inert gas, is injected in the underground formation to lower the oil viscosity and surface tension and increase the oil ...
