Enhanced oil recovery |
| abstract |
A process for petroleum recovery from an underground deposit by injecting hydrogen-rich gas in the absence of added hydrogenation catalysts into the underground deposit, the gas and deposit being at temperatures of less than 300 DEG F., maintaining the hydrogen-rich gas in contact with the petroleum at temperatures of less than 300 DEG F. for a time sufficient to reduce to desired levels viscosity and sulfur content of the petroleum by reaction with the hydrogen followed by recovery of the petroleum from the underground deposit. One embodiment is specifically set forth injecting carbon dioxide into the underground deposit after the reaction of the petroleum and hydrogen to increase the petroleum mobility ratio and to utilize both the hydrogen and carbon dioxide produced by partial oxidation of produced petroleum at the well site and resulting in as low as down to about 20 percent of the original oil in place remaining in the reservoir. |
