摘要： A process for recovering oil from a subterranean reservoir in which a surfactant slug injected into the formation via an injection well is passed through the formation and oil is recovered via a production well penetrating the formation. In this process a tapered surfactant concentration slug is employed in which the surfactant concentraction is increased, either incrementally or gradually, during the slug injection time.

摘要： Disclosed is a petroleum recovery method for recovering petroleum from subterranean formations containing water having high salinity and/or divalent ion concentration, employing an aqueous surfactant-containing fluid which is designed to effect low surface tension displacement of petroleum in the formation in the presence of high salinity water. The improvement comprises injecting the total desired volume of surfactant in the form of a plurality of relatively small slugs of surfactant fluid, and alternatingly injecting similarly small pore volume slugs of fresh, low salinity solution of hydrophilic polymer. The total pore volume of surfactant-containing fluid injected is ordinarily from 0.01 to 1.00 and preferably from 0.20 to 0.50 pore volumes. This total amount of surfactant fluid is injected in from 2 to 15 and preferably from 3 to 6 separate discrete slugs.Each slug of surfactant fluid is followed by injecting a quantity of low salinity, relatively fresh water solution of polymer, e.g. of salinity less than about 10,000 and preferably less than 1000 parts per million total dissolved solids. The volume of each slug of lower salinity polymer solution is ordinarily from 0.5 to 5.0 and preferably 1 to 2 times the volume of the preceding surfactant fluid slug.

摘要： A process for recovering oil from a subterranean reservoir in which a slug comprising an aqueous polymer solution containing a small amount of surfactant injected into the formation via an injection well is forced through the formation and oil is recovered via a production well penetrating the formation. In this process the concentration of the surfactant in the slug of the aqueous polymer solution is tapered by increasing the concentration of the surfactant either incrementally, gradually or by any other convenient method during the slug injection time.

摘要： This invention comprises two steps for improving in situ combustion in shallow reservoirs: (1) use small well patterns preferably with injection to producing wells distance about 200 to 250 feet; and (2) after the front reaches a distance where the air flux is about 5 SCF/(ft.sup.2 -hr), or expressed another way, where the rate of frontal advance is about 0.4 ft/day, allow the air to "ride" on top of the pay zone while simultaneously water is injected at the oil-water contact below the air entry at the sand face of the injection well.

The improvement comprises injecting the total desired volume of surfactant in the form of a plurality of relatively small slugs of surfactant fluid, and alternatingly injecting similarly small pore volume slugs of fluid comprising fresh water, e.g. salinities less than 10,000 parts per million and preferably less than 1000 parts per million total dissolved solids, and having dissolved or dispersed therein an effective amount of a sacrificial agent such as a water soluble lignosulfonate salt. The total pore volume of surfactant-containing fluid injected is ordinarily from 0.01 to 1.00 and preferably from 0.20 to 0.50 pore volumes. This total amount of surfactant fluid is injected in from 2 to 15 and preferably from 3 to 6 separate discrete slugs. Each slug of surfactant fluid is followed by injecting a quantity of fresh water containing the sacrificial agent. The volume of each fresh water sacrificial agent slug is ordinarily from 0.5 to 5.0 and preferably 1 to 2 times the volume of the preceding surfactant fluid slug.

摘要： The invention process is a method of conducting in situ combustion in heavy oil or tar sand reservoirs wherein carbon dioxide is injected into the formation prior to, during, or prior to and during in situ combustion. The carbon dioxide may be injected concurrently with the injection of the oxygen-containing gas or the oxygen-containing gas and carbon dioxide may be injected in alternate slugs. The injection of carbon dioxide aids in situ combustion by lowering the viscosity of the oil, creating channels in the heavy oil deposits for the passage of the oxygen-containing gas and increasing the mobility of oil ahead of the combustion front.
