Abstract: A vertical miscible recovery process for the recovery of oil from an oil-bearing reservoir wherein a miscible slug is established ''''in-situ,'''' at the crest of the oil column or at the gas-oil interface by the separate and simultaneous injection of a stream of the light constituents and a stream of the heavy constituents comprising the miscible slug, followed by the injection of a driving fluid to displace the slug and the reservoir oil downward thru the reservoir.

Abstract: A method of treating underground formations, especially those containing clays or clay-like materials which are sensitive to fresh water, to desensitize the clays so they will not swell or disperse on contact with fresh water. The treatment consists of contacting the clay-containing formation with solutions which accomplish the electroless deposition of metal on the clay particles. Optionally, the formation can be resin coated prior to electroless plating.

Abstract: A miscible flood process for the recovery of hydrocarbons from a hydrocarbon-bearing reservoir having a gas saturation in which a hydrocarbon solvent that has first contact miscibility with the reservoir hydrocarbon liquid is injected into the reservoir and which is thereafter followed by a drive fluid to move the previously injected solvent thru the reservoir, thereby displacing the reservoir hydrocarbons to a production well from which they are produced.

Abstract: A miscible flood process for the recovery of hydrocarbons from a hydrocarbon-bearing reservoir having a gas saturation is effected by the injection of a hydrocarbon solvent that is conditionally miscible with the reservoir hydrocarbon liquid and which is thereafter followed by a drive fluid to move the previously injected solvent thru the reservoir, thereby displacing the reservoir hydrocarbons to a production well from which they are produced.
