Definitions
- the subject of the present invention is an improved procedure for injecting and transporting particles, in particular microorganisms, in a natural porous medium.
- the oil recovery techniques used effectively lead to the extraction of a maximum of 35 to 40% of the crude oil contained in a tank.
- the improved recovery techniques consist in extracting all or part of this residual oil, in particular by sweeping the area with water, aiming either to modify the properties of the oil in place, or to modify the properties of the water. sweeping by increasing its viscosity by adding water-soluble organic polymers or by attenuating the repulsio phenomena between water and oil by adding surfactants.
- polymeric or surfactant compounds used in these various types of process can be either synthetic, manufactured by chemical route, or natural e for example manufactured by microbiological way by using microorganisms, bacteria in particular, likely to transform by metabolization of suitable carbonaceous substrates , such as sugars or hydrocarbons.
- European patent application No. 073 612 illustrates the use of mixtures of the xanthan biopolymer and surfactants of the polyglycol type to control the mobility of the solution.
- in-situ production naturally depends on the selection of the appropriate strains capable of developing in the environment of the reservoir, but also on the capacity to send to destination, that is to say the formation to be treated, the microorganism without over the long distance to be traversed, it is blocked in an area with low permeability or that on the way, it encounters a stimulating growth substrate which causes its multiplication and / or the production of compounds creating a plug which can , for example, lead to clogging of the injection well.
- the success of such a process therefore depends very much on the quality of the migration of cells within porous media which exhibit significant variations in porosity and permeability. This major difficulty certainly explains why this type of process has rarely been used by the petroleum industry and essentially as a final solution, in the event that the well is ultimately intended to be closed.
- the object of the invention is to overcome this drawback by proposing means promoting the transit of particulate suspensions, especially bacterial, in natural porous media.
- the subject of the invention is a process for injecting and propagating solid particles of small dimensions in a natural porous medium, characterized in that, in a first step, said medium is conditioned by sweeping by means of a balanced aqueous solution containing at least one hydrocarbon-based compound chosen from water-soluble or water-dispersible polymers and anionic surfactants, then, in a second step, a plug of solid particles suspended in a balanced aqueous medium is injected into said medium and containing in addition at least one hydrocarbon compound chosen from water-soluble or water-dispersible polymers and anionic surfactants and in a third step, said particle plug is pushed by a suitable aqueous medium.
- At least one hydrocarbon compound chosen from water-soluble or water-dispersible polymers and anionic surfactants will be added to the thrust medium.
- the hydrocarbon compounds used during each of the different steps may be the same or different. Their nature is independent of the solid particle injected and propagated.
- the method of the invention is applicable to the injection and propagation within porous media of suspensions of small particles, called micron particles, that is to say of which the average diameter is less than or equal to about 10.10 ⁇ 6 m.
- the choice of particles to inject will depend on the specific application envisaged. These particles may be of natural and / or mineral origin, for example, bentonites, clays or latex. They may be formed in a preferred application of the process by bacterial cells capable of producing in situ compounds allowing suitable treatment of the porous medium where they are implanted.
- viable, non-pathogenic bacterial cells are used as particles, which are used under non-proliferative conditions.
- bacterial cells will be, for example:
- aqueous solutions or media used in the process must be balanced.
- balanced is meant, in the present application, an aqueous solution or medium compatible with the water of the porous medium to be treated, which can be achieved, for example, by adding to said medium or solution of the main salts of the porous medium to treat.
- the presence of salts within the suspension is important for a specific propagation of the particles injected within the porous medium. Indeed, it avoids the mobilization of clays or any other colloidal particle present in the porous medium and moreover, it preserves the integrity of the transported particles, in particular if they are bacterial cells, by limiting the phenomena of swelling osmotic. It is important that the fluid injected is compatible with the chemical nature of the porous medium treated.
- the ionic composition of the fluid will be for example that of a reconstituted reservoir water, comprising MgCl 2 , 6H 2 0; CaCl 2 , 2H 2 0; K 2 S0 4 ; Na 2 S0 4 ; FeS0 4 , 7H 2 0; NaCl. It may be, in certain cases, very simplified and involve only a single salt (NaCl) or a mixture of two salts NaCl and CaCl 2 , the proportion of which can be varied according to the nature of the porous medium to be treated.
- the hydrocarbon compound used during one of the steps may be an anionic surfactant which will be used alone or in admixture with other anionic or nonionic surfactants.
- the total concentration of surfactants will generally be between 10 ⁇ 5 mole.l “1 and 10 " 1 mole.l “1 and preferably between 10 ⁇ 5 and 10 ⁇ 3 mole.l " 1 .
- concentration of the surfactant in the aqueous medium will depend on the choice of surfactant and the geochemical nature of the formation to be treated: pH and salinity of the formation in particular.
- the concentration of surfactant, and the total quantity to be injected will depend on the salinity of the formation water, that is to say its content of alkaline cation and its content of alkaline earth cations.
- the salinity is due to a high concentration of alkaline cation, the quantity of surfactant necessary for the process will be relatively less important than in the presence of alkaline-earth cations.
- anionic surfactant it is possible to use, for example:
- - soaps from fatty acids such as sodium or potassium salts of 10 -C 24 saturated or unsaturated fatty acids or derivatives of aminocarboxylic acids such as sodium N-lauryl sarconisate, - sulphates and sulphated products such than alkaline alkyl sulfates of the sodium laurysulfate type: polyoxyethylenated fatty alcohol sulfates, polyoxyethylenated alkylphenol sulfates, polyoxyethylenated arylalkylphenol sulfates, - phosphoric esters of oxyethylenated derivatives such as polyoxyethylene fatty alcohol phosphates, polyoxyethylenated alkylphenol phosphates, polyoxyethylenated arylalkylphenol phosphates, alkali sulfonates such as C 4 -C 30 alkyl sulfoesters of the sodium dialkylsulfosucc
- the hydrocarbon compound used during one of the stages may be a water-soluble or water-dispersible viscosifying polymer of high molecular weight.
- the presence of this polymer makes it possible in particular to stabilize the suspension of particles.
- viscosifying polymer of high molecular weight is meant a polymer having a mass greater than 500,000 daltons and preferably between 1 and 10 million daltons. This polymer must be insensitive to the action of bacteria which may be present.
- polymers which can be used in the process of the invention include: synthetic polymers such as partially hydrolyzed polyacrylamides, acrylamide-acrylic acid copolymers, acrylamide-acrylate copolymers, salified polyacrylates, salified polymethacrylates , partially hydrolyzed polyacrylonitriles, sulfonate polystyrenes, sulfonated styrene-maleic anhydride copolymers, etc.
- - biopolymers such as xanthan, scleroglucan, dextran, polyhydroxybutyrates (PHB), mannans, pullulan, curdlane, ., cellulose derivatives: carboxymethylcellulose (CMC), hydroxypropylmethylcellulose, carboxymethylhydroxy-ethylcellulose ..., natural polymers: gum arabic, alginates.
- the polymer content of the aqueous injection medium will generally be between 10 and 5000 pp and preferably between 50 and 450 ppm.
- the preferred polymer of the process of the invention will be a polyacrylamide (PAA), partially hydrolyzed.
- the degree of hydrolysis will generally be between 10 and 70% and preferably between 15 and 35%.
- the aqueous medium for injecting the particles during the second stage will comprise, alongside the salts, a mixture of water-soluble or water-dispersible polymers and of anionic surfactant.
- the contents of the aqueous injection medium polymers and surfactants will be analogous to those described above for the processes using the surfactant or the polymer alone.
- the quantity of particulate suspensions, in particular bacteria, to be injected must be commensurate with the pore volume to be treated. In the case of the treatment of an oil deposit, these will be high permeability zones which generally represent at most a few% of the total volume of the porous medium.
- the quantity of suspensions to be injected will take into account this pore volume to be treated, as well as, to a certain extent, the pore volume of the transit zone, that is to say, the distance separating the injection zone from the area to be treated.
- the quantity of particles to be suspended is generally between 10 5 and 10 particles per cm 3 .
- an aqueous fluid containing the hydrocarbon compounds without the particles is injected, then an aqueous injection medium containing all of the elements, the total amount of surfactant and / or of polymer must be sufficient to ensure good conditioning zones' through which the particle suspension must pass.
- the total volume of the aqueous fluid solution used for the first two stages will rarely exceed 30% of the total volume of the porous medium and will often be less than 20% of this volume, the amount of hydrocarbon compound will be optimized according to the specific surface of the porous medium.
- the volume of the suspension injected during the second stage will generally represent between 10 and 50% of the volume injected in the first stage and will generally be between 2 and 10% of the pore volume total porous medium.
