    摘要: 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.

    摘要: A method for recovery of hydrocarbons from a subterranean reservoir by operating adjacent injector producer well pairs under conditions of steam assisted gravity drainage (SAGD) with a lateral drainage well between and substantially parallel to them; the lateral drainage well is operated under conditions of intermittent steam injection and alternating oil, water and gas production; NCG is co-injected with steam into both the injector wells and the lateral drainage well at selected intervals, and in selected quantities in order to control the steam saturation of the SAGD steam chamber and the rise of the steam chamber, and to encourage lateral fluid communication between the adjacent well pairs and the LD well; controlling gas injection and production in order to control the rise of the steam chamber to improve production of oil; operating the well pairs and the LD well under conditions of a steam chamber pressure that is initially and briefly high to establish a steam chamber, but thereafter may be reduced to as low as 200 kPa; operating this low pressure SAGD in reservoirs that are at low pressure, due to factors such as depleted gas caps, regional geology, lack of cap rock, thief zones, or other low pressure zone or loss zones.

    摘要: A method for recovery of hydrocarbons from a subterranean reservoir is described. Adjacent injector producer well pairs are operated under conditions of steam assisted gravity drainage with a lateral drainage well between them. The lateral drainage well is operated under conditions of intermittent steam injection and alternating oil, water and gas production. NCG is co-injected with steam at selected intervals and in selected quantities in order to control the steam saturation of the SAGD steam chamber and the rise of the steam chamber, and to encourage lateral fluid communication between the adjacent well pairs and the LD well to control the rise of the steam chamber.
