    Abstract: Heavy petroleum may be recovered from an underground formation by in situ combustion followed by injection of a hydrocarbon, which may be produced petroleum which thermally decomposes into light, low viscosity liquids that readily flow toward producing wells and petroleum coke which deposits on the reservoir formation, thereby providing fuel for another in situ combustion and repeating the cycle of operation until substantially all of the immobile, heavy petroleum is converted into a low viscosity liquid and/or gas.

    Abstract: A petroleum recovery method employing a mixed solvent for use in formation in contact with and over-laying a substantially water saturated porous formation which is prone to bottom water coning. The mixed solvent density is less than the density of water and greater than the density of the formation petroleum, and has a boiling point less than the boiling point of the formation petroleum. The solvent is injected into the formation near the petroleum-water interface and the mixture comprising solvent and petroleum is recovered from production wells. The solvent may be separated from the produced petroleum-solvent mixture by distillation and recondensation for reinjection into the formation.

    Abstract: A novel method of secondary recovery of oil from subterranean reservoirs is provided wherein a fluid is used to drive the oil in the reservoir to production wells. This driving fluid is a mixture of water and colloidal silica. The driving fluid has a mobility ratio relative to the oil in the reservoir such that the driving fluid will maintain a flat face against the oil being driven to production wells and thus a high sweep efficiency of the reservoir will result.

    Abstract: Hot fluid may be injected into a subterranean hydrocarbon reservoir with little heat loss through the casing walls on the way down to the injection zone by placing tubing inside the casing of an injection well and injecting a hot fluid or vapor into the tubing and a cold fluid into the annulus between the tubing and casing.
