| 20100200249 | GAS-ASSISTED PROCESS FOR IN-SITU BITUMEN RECOVERY FROM CARBONATE RESERVOIRS - A method for producing bitumen or heavy oil from a subterranean reservoir comprising a carbonate mineral solid matrix comprising injection or co-injection of a gas other than carbon dioxide, injection or co-injection of a carbon containing gas containing a relatively low amount of carbon dioxide, injection of steam providing bicarbonate/alkalinity, or increasing the subterranean reservoir pressure, such that the dissolution and re-precipitation of carbonates is suppressed thereby. | 08-12-2010 |
