Definitions
- the present invention relates to the field of petroleum extraction, and more particularly to techniques known as enhanced oil recovery.
- a fluid is injected (re-injection of the water produced diluted or not, injection of sea or river water, or injection of gas, for example) into the hydrocarbon tank, with a view to exerting within the tank, an overpressure capable of entraining the oil towards the production well (s).
- a common technique in this context is the injection of water (also known as flooding or “waterflooding”), in which large volumes of water are injected under pressure into the reservoir via injector wells. The injected water entrains part of the oil it encounters and pushes it towards one or more producing wells.
- the surfactants usually recommended for EOR are typically anionic surfactants, generally of the sulfate or sulfonate type.
- anionic surfactants generally of the sulfate or sulfonate type.
- compositions useful for EOR which comprise particular sulfonates, namely internal ketones sulfonated in alpha of the ketone group, more precisely mixtures of mono-sulfonated ketones (c that is to say sulfonated on only one of the alpha positions of the carbonyl group) and di-sulfonated (sulfonated on both positions).
- the compositions of WO 2016/177817 are typically obtained by sulfonation of internal ketones.
- the “Mobility Reduction” (noted Rm), to which reference is made in the present description, is a well-known parameter in the field of petroleum extraction, and it is applied here to the injection of an aqueous solution surfactant.
- Rm aqueous solution of surfactant comprising at least one surfactant and an aqueous solvent medium (which can typically be water or brine)
- the value of the reduction in mobility is obtained from the Darcy relation: it corresponds the ratio between the value of the pressure drop measured during the injection of the aqueous solution of surfactants considered at a given flow rate (DR solution) compared to the value of the pressure drop measured, before injection of the surfactant solution, during the injection of the aqueous solvent medium without the surfactants (DR solvent):
- Q represents the flow rate of a fluid of viscosity h
- DR represents the pressure drop caused by the fluid flow
- k represents the permeability which can be defined as the hydraulic conductivity of the porous medium, which is expressed in Darcy (1 D "0.987 pm 2 ).
- the reduction in mobility Rm defined above corresponds to the effective viscosity of the surfactant solution in the porous medium and it is by definition greater than 1.
- a surfactant solution proves to be all the more difficult to inject as its value of Rm is high.
- An object of the present invention is to provide compositions based on sulfonated internal ketones, but not leading to this phenomenon of amplification of the reduction in mobility over time.
- the inventors have demonstrated an original technical solution: it turns out that the effect of increasing the reduction in mobility can be counteracted by using the internal sulfonated ketones together with a sufficient quantity of non-internal ketones. sulfonated.
- the work carried out by the inventors in the context of the present invention shows that, if non-sulfonated internal ketones are added to a composition based on sulfonated internal ketones, there is a limit value of the molar concentration of non-sulphonated ketones (defined by the ratio of the quantity of non-sulphonated ketones compared to the total quantity of sulphonated and non-sulphonated ketones), hereinafter called "limit molar concentration" such that:
- the reduction in mobility reaches a limit value after a short stabilization period, and the reduction mobility then remains substantially stable over time.
- the limiting molar concentration of non-sulfonated ketones can vary to a large extent depending on the sulfonated ketones and non-sulfonated ketones used.
- the limit molar concentration can be established experimentally by iteration, by testing a molar concentration of non-sulfonated ketones and by observing for this concentration the evolution obtained for the reduction mobility. If the reduction in mobility stabilizes, the molar concentration tested is greater than or equal to the limit ratio, otherwise it is lower.
- the limit molar concentration of non-sulfonated ketones for a given sulfonated ketone / non-sulfonated ketone system is typically greater than 10% (it is for example of the order of 15% for the composition of the example illustrative described in more detail at the end of this description).
- non-sulfonated ketones are preferably used as an additive, with a molar concentration of ketones not preferably less than 50%, typically less than or equal to 30%, or even 25 %.
- the subject of the present invention is the advantageous compositions identified by the inventors, namely the compositions of sulfonated internal ketones comprising non-sulfonated ketones in an amount greater than or equal to the limit value allowing stabilization of the reduced mobility.
- compositions comprising:
- (B) non-sulfonated internal ketones with a molar ratio B / (A + B), corresponding to the molar concentration of non-sulfonated ketones, which is greater than or equal to the limit molar concentration of non-sulfonated ketones from which a stabilization of the reduction in mobility is observed when injecting the mixture of said sulfonated internal ketones and said non-sulfonated internal ketones into a porous medium.
