The inhibition of anionic surfactant retention phenomena in an oil reservoir, especially in a carbonate-based or argillaceous reservoir, by the use of at least one compound corresponding to the formula R&#x2014;O-(A)m-H, in which R is a hydrocarbon-based group comprising from 6 to 40 carbon atoms, A is a hexose or pentose unit, and m is a non-zero number ranging from 1 to 10, is described herein.

Alkyl polyglucoside desorbents for enhanced oil recovery

Provided is a process of enhanced oil recovery from an oil reservoir of an underground formation by using a compound of formula (I) to inhibit the phenomena of retention of anionic surfactants within an oil-bearing reservoir, such as a carbonate or clay reservoir: R&#x2014;O&#x2014;(&#x2014;CH&#x2014;CH(&#x2014;CH)&#x2014;O&#x2014;)&#x2014;(&#x2014;CH&#x2014;CH&#x2014;O&#x2014;)&#x2014;H, wherein: R is a hydrocarbon-based group comprising from 6 to 40 carbons; m ranges from 0 to 20; n is greater than m and ranges from 5 to 40.

Desorbants for enhanced oil recovery

An enhanced oil recovery method using injection of aqueous polymer solutions into the reservoir rock, includes the stages of: injecting a first aqueous solution of non-associative hydrophilic polymers into the reservoir in a predetermined proportion so that they adsorb on the reservoir rock; and then injecting a second aqueous solution of associative polymers into the reservoir for oil recovery, with limited adsorption considering the adsorption of the non-associative polymers of the first solution.

Enhanced oil recovery method using associative polymers

The invention relates to an enhancing oil recovery method by injecting into a subterranean oil formation an aqueous flooding fluid comprising at least one injecting galactomannan polymer substituted by at least one sulfonation agent. The invention also relates to an flooding fluid having better injectivity properties than existing flooding fluids.

Flooding fluid and enhancing oil recovery method

The present invention relates to a method of treating porous and permeable underground formations or cavities of reservoir rock or sand foundation type. The method consists in injecting a liquid composition comprising microgels into the formations in order to reduce the production of water, gas or sands, and/or for zone abandonment.

Method of treating underground formations or cavities by microgels

The present invention relates to an optimized method for modelling flows in a geological hydrocarbon reservoir, comprising injecting an aqueous polymer solution to sweep the hydrocarbons, determining a relationship between a parameter linked with the mobility reduction of the solution in the reservoir and the water saturation, and accounting for this relationship in a flow simulator to achieve modelling.
