Abstract

This patent describes a process for the recovery of oil from a petroleum reservoir by improving steam sweep efficiency during steam-flooding, wherein a foaming agent is added to divert steam to unswept zones and the reservoir is penetrated by at least one injection well and at least one production. It comprises injecting steam and a surfactant solution comprising the foaming agent into an injection well, while concurrently and separately injecting an additional amount of liquid water into the injection well to generate a foam and thereby increase the pressure at the injection well; and recovering oil from a production well.

Steam foam surfactants enriched in alpha olefin disulfonates for enhanced oil recovery

Patent Borchardt, J; Lau, H

This patent describes a process for recovering oil from a reservoir penetrated by at least one injection well and at least one production well. It comprises displacing through the reservoir a steam form-forming mixture of steam and an olefin sulfonate surfactant, the olefin sulfonate surfactant containing at least about 25 wt % olefin disulfonate wherein the olefin sulfonate surfactant is derived from olefins with carbon numbers in the range of about 16 to 28; and recovering displaced hydrocarbons from the production well.

Alkali-enhanced steam foam oil recovery process

Patent Lau, H

This patent describes a process in which steam and steam-foaming surfactant are injected into a subterranean reservoir for displacing a relatively acidic oil toward a production location. An improvement is described which consisits of: injecting into the reservoir, at least as soon as at least some portion of the steam is injected, (a) a kind and amount of water soluble, alkaline material effective for ion-exchanging multivalent ions from the reservoir rocks and precipitating compounds containing those ions and for causing the aqueous liquid phase of the injected fluid to form soaps of substantially all of the petroleum acids in themore »« less
Method for foam emplacement in gas flooding for enhanced oil recovery

Patent Shang, Chou

A method is described for generating foam by improving the sweep efficiency of gas and steam floods by reducing the permeability of higher permeability thief zones of an oil bearing subterranean reservoir having heterogeneous and/or fracture permeability and being penetrated by at least one well, said method comprising: (a) injecting a controlled quantity of a first foam-forming surfactant into an injector well of said reservoir having at least one of said higher permeability zones to presaturate said reservoir; and (b) co-injecting controlled quantities of a gas and a subsequent foam-forming surfactant into the same injector well of said reservoir somore »« less
Sequential detection foam process for enhanced oil recovery

Patent Wall, R

This patent describes a method of enhanced recovery of oil from a petroleum reservoir. It comprises injecting into the reservoir an oil-mobilizing agent comprising a gas and a surfactant, which agent is capable of mobilizing oil present in oil-bearing formation in the reservoir, in an amount sufficient to reduce the oil concentration in the oil-bearing formation; stopping the injection of the oil-mobilizing agent; and injecting into the formation steam and an alpha-olefin sulfonate dimer surfactant or an alpha-olefin sulfonate surfactant sufficient to form a foam in areas of reduced oil concentration and thereby divert steam from the areas to areasmore »« less
Steam enhanced oil recovery method using dialkyl aromatic sulfonates

Patent Danzik, M

This patent describes a method of enhanced recovery of oil from a petroleum reservoir during steam injection into the reservoir. It comprises: periodically injecting steam and an anionic surfactant into the reservoir from a known depth interval in a well to form a foam in the presence of residual oil in high stem permeable channels of the formation, the anionic surfactant including an effective amount of an alkyl aromatic sulfonate component having average molecular weight of from about 400 to about 600 and comprising at least 2 alkyl groups wherein one alkyl group is linear comprising from about 8 tomore »« less
