摘要： In a steam soak oil recovery process in a heavy oil reservoir which is susceptible to gravity override, improved results are obtained by injecting the steam in the form of a steam-foam-forming mixture which has a chemical selectivity for being more mobile within the reservoir in contact with the reservoir oil than in the absence of that oil.

摘要： Steam mobility-reducing capability of an olefin sulfonate-containing surfactant formulation for reducing the mobility of steam of a selected quality within a selected subterranean oil-containing reservoir is tested. Steam of the selected quality and a steam-containing fluid which has substantially the same quality containing the surfactant formulation, an electrolyte and a noncondensable gas upflow through columns of permeable porous mediums containing the reservoir oil. The mass flow rates through the columns are substantially equivalent to a selected flow rate in a near-well portion of the reservoir. Steady-state pressure within the columns are measured and the permeability reducing factor of the surfactant formulation is calculated from the pressure measurements.

摘要： In a viscous oil reservoir in which the stratification of the rock permeability is insufficient to confine steam within the most permeable strata, oil can be produced by forming and expanding a steam channel through which steam is flowed and oil is produced. Steam is injected and fluid is produced at rates causing a steam channel to be extended between locations that are horizontally separated. A foam-forming mixture of steam, noncondensable gas and surfactant is then injected into the steam channel to provide foam and a relatively high pressure gradient within the channel, without plugging the channel. A flow of steam-containing fluid through the steam channel is continued in a manner such that the magnitudes of the pressure gradient, the rate of oil production, and the rate of steam channel expansion exceed those which could be provided by steam alone.
