Description

METHOD FOR OBTAINING AN ASPHALTENE PARTICLE DISPERSING ADDITIVE FIELD OF INVENTION The present invention relates to methods for obtaining asphaltene particle dispersing additives, more particularly to a method for obtaining an asphaltene particle dispersing additive. BACKGROUND OF THE INVENTION Currently, drilling through unconsolidated sands in heavy and extra-heavy oil reservoirs presents a challenge in the development of new technologies for oil well cleaning. This is primarily due to the physicochemical characteristics of heavy crude, which result in low well cleaning efficiency and cause the oil to adhere to drilling tools, affecting the rate of penetration (ROP) and increasing torque values ​​during drilling. It should be noted that the use of dispersant additives in the oil industry is quite common due to accretion, which is the addition of matter to a body, increasing its volume. Anti-accretion additives are designed to inhibit the adhesion of bitumen, or heavy crude, to the metal surface, as well as to help mitigate the agglomeration of drill cuttings.Anti-accretion additives contribute to improving the rate of penetration (ROP) and reducing non-productive time (NPT). The use of conventional synthetic systems has shown significant failures in oil well cleaning. Therefore, it is important to achieve high-efficiency oil extraction. To achieve this greater efficiency, various chemical products, materials, and processes are constantly being studied to improve oil extraction performance. Synthetic dispersant additives are chemical products used to reduce the incompatibility of asphaltenes with organic solvents, thereby facilitating their incorporation into the environment or natural degradation.However, currently available dispersant additives are often toxic to the environment, require complex and expensive production methods, which impacts the final cost to the consumer. Furthermore, existing dispersants are ineffective in long-reach deviated oil wells and in depleted or low-productivity reservoirs. One of the solutions proposed in the prior art related to dispersants is described in US patent 8628626, which relates to a method for preparing a terpene-based solvent comprising the steps of: a) obtaining at least one terpene-based solvent; and b) mixing the terpene-based solvent with a solvent extender comprising a microemulsion of: i) a mixture of dibasic esters selected from the group consisting of dialkyl methylglutarate, dialkyl adipate, dialkyl ethylsuccinate, dialkyl succinate, dialkyl glutarate, and any combination thereof; ii) at least one surfactant selected from the group consisting of a terpene alkoxylate, an alcohol alkoxylate, and any combination thereof; and iii) water; to form a rinseable mixture, wherein the rinseable mixture is capable of cleaning a contaminated substrate.However, the solvent described uses tribological or lubricity reactions, which are not effective in clearing pipe blockages caused by poor hole cleaning. For its part, document US20200377809 refers to a heavy crude oil additive comprising a naphtha and a pyrolysis oil. The additive further comprises at least one terpene, one or more citrus isolates, and one or more nonionic surfactants. The method for preparing the heavy crude oil additive comprises: a) adding at least one component selected from the group comprising a terpene, one or more citrus isolates, and one or more nonionic surfactants to a pyrolysis oil to form a first additive; b) adding the first additive to a naphtha to form a second additive; and c) adding the second additive to the heavy crude oil. However, the heavy crude oil additive does not alter the crude oil's gravity or the phenomena associated with viscosity reduction. Another example is document US10544355, which describes a method for treating a formation crude oil well comprising injecting an emulsion or microemulsion into the formation crude oil well to stimulate the displacement of residual aqueous treatment fluid by the formation crude oil and increase formation crude oil production from the well. The emulsion or microemulsion comprises water, a terpene, and a surfactant. The surfactant comprises a fatty acid polyglycol ester having 6 to 24 carbon atoms and 2 to 40 ethylene oxide units, and the terpene has a phase inversion temperature greater than or equal to 43°C. However, the described method is not efficient in long-reach deviated well drilling because accretion is greater due to the agglomeration of rock cuttings. In accordance with the above, there is a need to develop a method for obtaining an asphaltene particle dispersant additive with high dispersion effectiveness in heavy crude oil and even in long-range deviated wells. OBJECTS OF THE INVENTION Considering the background of the prior art, it is an object of the present invention to provide a method for obtaining an asphaltene particle dispersant additive that allows obtaining a dispersant with high dispersion effectiveness in heavy crude oil and even in long-range deviated wells. Furthermore, another object of the present invention is to provide a method for obtaining an asphaltene particle dispersant additive that uses environmentally friendly and economical reagents. Another object of the present invention is a method for obtaining an asphaltene particle dispersant additive that has a synergistic effect on inhibiting accretion caused by nano-aggregates of asphaltene macromolecules present in heavy crude oil. Another object of the present invention is to provide a method for obtaining an asphaltene particle dispersant additive with improved solubility and thermal properties that allow for an improvement in the anti-accretion activity of the dispersant. Furthermore, another object of the present invention is to provide a method for obtaining an asphaltene particle dispersant additive that can be used in water-based drilling fluids (WBDF). Finally, it is an object of the present invention to provide a method for obtaining an asphaltene particle dispersant additive that does not interfere with other components of the drilling fluid. These and other objects are achieved by a method of obtaining an asphaltene particle dispersing additive in accordance with the present invention.

A second aspect of the present invention relates to an asphaltene particle dispersing additive obtained by a method for obtaining an asphaltene particle dispersing additive in accordance with the present invention. In a preferred embodiment of the present invention, the asphaltene particle dispersing additive has a molecular weight of 103 g / mol. Preferably, the asphaltene particle dispersing additive has thermal properties that improve its anti-accretion activity. The thermal properties of the asphaltene particle dispersing additive may include a typical thermal decomposition temperature in a nitrogen atmosphere of 350°C and a glass transition temperature between 80 and 90°C. Additionally, the asphaltene particle dispersing additive exhibits complete solubility in ethylene glycol butyl ether over a temperature range of 20 to 150°C. The asphaltene particle dispersant additive obtained exhibits a higher glass transition temperature of between 80 - 90 °C in the main carbon chain structure, compared to limonene and pPinene alone. In a preferred embodiment of the present invention, the asphaltene particle dispersant additive is a poly(R+Limonene-co^Pinene). The present invention will be better understood from the following examples, which are presented for illustrative purposes only to allow a full understanding of the preferred embodiments of the present invention, without implying that there are no other unillustrated embodiments that can be put into practice based on the detailed description above. EXAMPLE 1 A test was carried out to exemplify the method of obtaining an asphaltene particle dispersant additive with R+limonene and βPryene in accordance with the present invention. In this example, the asphaltene particle dispersant was synthesized by cationic copolymerization using the ecocatalyst Maghnite-H'1. The catalyst was obtained by adding 150 mL of water, 30 g of montmorillonite powder, and 100 mL of a 0.5 M aqueous hydrochloric acid solution. The reaction was carried out at 50°C under constant stirring for 48 h. Figure 1 shows a schematic representation of Maghnite-H+. At the end of the reaction, the suspension was filtered, washed several times with distilled water until a pH of 7 was obtained, and then the Maghnite-H'1 was dried in an oven for 24 h at 100°C. Then, in a positive nitrogen atmosphere, 0.1 moles of R+ Limonene and 0.1 moles of βPine were added to a flask containing 10% w / w of Magnite-H+1 dissolved in CH2CI2; the polymerization reaction was carried out at -5 °C for six hours.Figure 2 shows a schematic of the asphaltene particle dispersant additive with R+limonene and β-Pyrene (BP) at a temperature of 5°C, for a time of 6 hours, and with 10% w / w of Magnnite-H+ 1 dissolved in CH2Cl2. The reaction mixture was then filtered, and the copolymer was precipitated in cold methanol, separated by filtration, and dried under vacuum. The resulting copolymer was a solid product. EXAMPLE 2 A test was performed to characterize the asphaltene particle dispersant additive obtained in example 1 of the present invention. For this test, asphaltene extractions were performed with n-heptane using an oil / solvent ratio of 1 g / 40 mL. The oil / solvent mixture was refluxed for 4 h, and the resulting solid was filtered and weighed. DLS measurements for average particle size and asphaltene distribution were performed on a Malvern 4700 instrument equipped with an argon laser (λ = 488 nm). For particle size measurement, 2 mL of the asphaltene dispersion in CH₂Cl₂ (1 and 2 mg / L) was added to a glass cuvette. The dispersion was then sonicated for 3 min at a frequency of 37 kHz and analyzed on the Malvern instrument. A similar procedure was performed for asphaltene particle dispersions in CH₂Cl₂ (2 and 4 mg / L). The asphaltene particle dispersant and the other asphaltenes were characterized by 1H NMR using a Jeol dual-channel NMR spectrometer and a 5 mm probe for the NP / FH liquid sample. The asphaltene particle dispersant and the asphaltenes were analyzed using a Nicolet iS50-Thermo Fisher Scientific FT-IR spectrometer. The asphaltene samples were mixed with 100 mg of dry KBr powder, then pressed with a die at a pressure of 10,000 to 15,000 psi until a clear, homogeneous disc was obtained. The disc was then analyzed using the FT-IR spectrometer. Figure 3 shows the transmittance measurement in the FTIR spectra of asphaltenes extracted from Mexican heavy crude oil, where their characteristic bands are observed. At 3600 cm1, a small peak is due to the stretching vibrations of OH and NH2; at 3080 cm1, the stretching vibrations of aromatic CH; the signal at 1600 cm1 is related to the aromatic stretching vibrations of C=C. The peaks between 2900 and 2800 cm1 correspond to the stretching mode of the methylene and ethylene groups, and the band at 14505 cm1 is associated with the bending vibration of the alkyl groups (CH3 and CH2). Figure 4 shows an FTIR amplification spectrum of A) R+Limonene (dashed line), pPinene (dashed line), and biopolymer (black line), B) Amplification of the spectral region between 850 and 900 cm⁻¹ with R+Limonene (dashed line), βPinene (dashed line), and biopolymer (black line). The superposition of the FTIR spectra of R+Limonene, βPinene, and poly(R+Limonene-co^Pinene) is shown in Figure 4. The bands at 2950–2800 cm⁻¹ correspond to the stretching mode of the methyl groups; the CH bending modes of the methyl and methylene groups are observed at 1490–1300 cm⁻¹. The band at 1600-1700 cm1 associated with the C=C stretching vibration, and the bands attributed to out-of-plane bending vibrations of CH bonded to C=C (850-900 cm-1) show a significant decrease indicating that copolymerization took place. The elemental composition of the asphaltenes obtained from the heavy crude oil supplied by IMP® was also analyzed using X-ray photoelectron spectroscopy (XPS). Table 1 shows the elemental compositions of the asphaltenes obtained from the Mexican heavy crude. TABLE 1 Element Asphaltenes of Mexican Heavy Crude [%] Asphaltenes reported by Abdallah & Taylor [%] C1S 85.30 78.00 - 88.70 S2p 2.98 0.30 - 10.30 N1S 2.21 0.20 - 3.30 OIS 6.14 0.30 - 4.90 As can be seen in Table 1, the XPS analysis shows that the typical elemental composition of asphaltenes is in the range as reported by Abdallah, WA, & Taylor, SD (2007). Surface characterization of adsorbed asphaltene on a stainless-steel surface. Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms, 258(1), 213-217. https: / / doi.Org / 10.1016 / j.nimb.2006.12.171, for different asphaltene sources. Figure 5 shows in section A) 1H NMR spectra for poly(R+limonene-Ppinene) and in section B) selected protons for determining the comonomer composition. Figure 5A shows the 1H NMR spectrum of poly(R+limonene-β-pinene). The peak [6] at 0.90 ppm corresponds to the protons of the limonene methyl group, and the peak at 0.8 ppm to the protons of the pinene methyl groups. Using the ratio of the areas of these peaks, it was found that PB contains 66.7% R+limonene and 33.3% β-pinene (Figure 5B). EXAMPLE 3 A test was performed to verify the effect of the asphaltene particle dispersant additive with R+limonene and βPryene obtained in example 1 on asphaltenes in accordance with the present invention. For this test, asphaltene dispersions (1 mg / L, 2 mg / L, and 4 mg / L) and mixtures of asphaltenes and the asphaltene particle dispersant additive with R+limonene and β-Pyro in dichloromethane were prepared. The dispersions were filtered through membranes capable of removing particles larger than 22 µm and then subjected to ultrasound for 3 min at a frequency of 37 kHz. A quartz / glass cell was used for particle size measurement, and the analysis was performed using a MALVERN Dynamic Light Scattering (DLS) instrument (Zetasizer Nano Series) equipped with a red laser with a wavelength of 632.8 nm. For the stability tests of asphaltene dispersions (1 mg / L, 2 mg / L, and 4 mg / L) and mixtures of 1 mg / L asphaltenes with 1 mg / L, 2 mg / L and 4 mg / L concentrations of asphaltene particle dispersant were prepared with R+limonene and β-Pyrene in dichloromethane. The stability of the dispersions was determined using the Turbiscan Lab® instrument, which was calibrated with silicone and Teflon standards. A 2 mL volume of the dispersions was used, and sedimentation measurements were performed for 30 min at 25 ± 1 °C. Figure 6 shows the particle size distribution of the asphaltene nanoaggregates obtained by DLS with the asphaltene particle dispersant additive CH / CL·, where three distributions between 1.8 and 25 nm are observed. The distribution with the highest quantity of nanoaggregates has an average particle size of 4.1 nm. The size, shape, and stability of asphaltene aggregates can vary considerably with the crude oil composition. The size of the asphaltene aggregates separated from heavy oil tartar was determined by small-angle X-ray scattering (SAXS) and scanning tunneling microscopy (STM), yielding an average length of 10 nm and a wide particle size distribution range of 2.5 to 35 nm. The data obtained were processed in the Tursoft Lab 2.2.0.82 software, and the Turbiscan TSI Stability Index was obtained according to equation 1 (Eq. 1). Τ5Ι=ΣΣ\χ€αηί( / ΐ)-χεαηί-1( / ϊ)\ΙιΗ (Eq. 1) Where; H = height of the vial; Scani = scan you; Scani-1 = scan you-1 The Turbiscan Stability Index (TSI) is a parameter that can be used to estimate suspension stability. This parameter is a statistical factor, and its value is obtained as the sum of all processes occurring in the sample under study. A reduction in the TSI indicates increased system stability, meaning that sedimentation is slower. Figure 5 shows a graphical representation of A) TSI percentage versus time for three asphaltene dispersions in CH2Cl2; B) the effect of asphaltene concentration on the TSI parameter. Figure 7A) shows the TSI curves as a function of time for the asphaltene dispersions in dichloromethane. It can be observed that the TSI value increases with increasing test time and that sedimentation is faster with increasing asphaltene concentration. Figure 7B) shows the TSI value of the three asphaltene samples 30 minutes after the start of the test. Figure 8 shows a graphical representation of: A) the % TSI parameter as a function of time for asphaltene dispersions in CH2Cl2 containing different concentrations of the asphaltene particle dispersing additive according to the present invention; B) the effect of the BP concentration on the TSI parameter. When the asphaltene particle dispersing additive according to the present invention was added to the asphaltene suspension, the TSI parameter value decreased, indicating greater stability. This reduction was more significant as the amount of asphaltene particle dispersing additive with R+limonene and β-Riene added increased. Figure 6 shows that the TSI parameter decreased from 1.8 to 1.38.This increase in suspension stability (lower TSI value) is due to the addition of the asphaltene particle dispersant additive according to the present invention, which causes deagglomeration and helps prevent the aggregation of asphaltene nanoparticles. Polymeric dispersant additives have been used to prevent asphaltenes from agglomerating. To act as an agglomeration inhibitor or dispersant of asphaltene aggregates, these polymers must have polar groups that interact with the asphaltenes and aliphatic chains that aid in their solubilization in solvents. Limonene can be used as a dispersant to remove and prevent asphaltene precipitation. A drilling fluid additive has been patented that uses a terpene, preferably d-limonene or dipentene, and a mineral or vegetable oil in its formulation. The additive is mixed with a water-based drilling mud at a concentration of 1–8% by volume. The additive exhibits a higher penetration rate, high lubricity, and low toxicity.Using molecular dynamics simulations of asphaltene aggregation in supercritical carbon dioxide with and without limonene, it was found that the addition of limonene resulted in a significant decrease in aggregation compared to pure CO2. In this test, the asphaltene particle dispersing additive with R+limonene and β-Riene obtained in Example 1 was used to deagglomerate or prevent agglomeration of the asphaltenes. Figure 9 shows the effect of adding the asphaltene particle dispersing additive with R+limonene and β-Riene (BP) according to the present invention to the asphaltene dispersions on the particle size distribution. This figure shows that the distributions shift toward smaller sizes when the asphaltene particle dispersing additive with R+limonene and β-Riene according to the present invention is added to obtain concentrations of 1, 2, or 4 mg / L in the dispersions. It should be noted that the asphaltene particle dispersant additive with R+limonene and BP according to the present invention was obtained by cationic polymerization. Three particle size distributions of asphaltene nanoaggregates in CH2CI2 are observed between 1.8 and 25 nm. The addition of BP to asphaltene dispersions shifts the particle sizes toward smaller sizes, and the TSI parameter value decreases, indicating greater dispersion stability; this reduction becomes more significant as the amount of BP added increases. Because BP is produced from natural materials (terpenes), it does not have the hazardous effects of synthetic polymers. In accordance with the above, it can be observed that the method of obtaining an asphaltene particle dispersant additive with R+limonene and βRiene has been devised as a dispersant with high dispersion effectiveness in heavy crude and even in long-range deviated wells, it being evident to any expert in the field that the embodiments of the invention as described above and illustrated in the accompanying drawings are merely illustrative and not limiting to the present invention, since numerous significant changes in its details are possible without departing from the scope of the invention. Therefore, the present invention shall not be considered restricted except as required by prior art and within the scope of the appended claims.
