“…Smart cements are, by definition, multifunctional materials that exhibit specific responses toward a specific stimulus and react in a measurable, reliable, and reproducible manner (Bogue 2012). Additionally, these particles have a significant influence on the mechanical performance of OWCs based on various factors (Zolotarev et al 2013): can be reinforced by the specific nanomaterial employed and can also make the composite piezoresistive and therefore self-sensing by taking advantage of their good electrical properties (e.g., electrical current density capabilities of CNTs of 4 ϫ 10 9 A/cm 2 ), allowing the composite to be capable of sensing strain, stress, cracks, and damage (Mangadlao et al 2015).…”

Annular sealants are used as static barriers to avoid fluid communication in-between zones and provide proper isolation of the different formations as well as support and protection to the casing. Therefore, the sealant can have a direct relationship to wellbore integrity. Data suggest more than 4 million hydrocarbon wells have been drilled globally; interestingly, some datasets indicate well integrity failure is highly variable (1.9 to 75%).Historically, sealants have been characterized for short-term placement properties up to the point at which the sealant is pressure tested and a log is performed to establish if the annulus is properly sealed. However, as hydrocarbon resources are becoming gradually depleted in easy-to-recover environments, harsher conditions are more common. Additionally, stimulation and enhanced oil recovery (EOR) techniques involving high-pressure and high-temperature (HP/HT) cycles during the entire well life pose significant challenges to the sealant's integrity.Sealant integrity issues can result in very high remediation costs, reduction of hydrocarbon production, and in some cases, loss of the well. All of these can lead to an increased cost per barrel of oil equivalent (BOE). During the last few decades, in view of the drastic changes in drilling conditions toward more challenging environments, the industry has opted for a sealant design approach, which considers all of the events that occur throughout the entire life of the well and their effects on integrity of the sealant and wellbore. This approach can be successful by employing analytical tools, which allow for synchronizing all of the different events and/or operations occurring during wellbore construction (from drilling to abandonment) with the different elements that encompass the wellbore architecture (geometry, formations, casing, and sealant). The use of these tools' forecasting capabilities can result in data-led decisions that allow operators to construct wellbores more efficiently and with more confidence, which should ultimately help reduce production costs.This study focuses on illustrating an analytical tool for predicting the sealant's performance in both onshore and offshore cases throughout the life of the well and determining how this affects wellbore economics in the long term. Moreover, this paper discusses how sealants have evolved from conventional Portland cements to elastic-, foamed-, glass-bead-extended cements, and epoxy-resins based on wellbore integrity predictions performed by analytical tools. The impact of nanomaterials in converting cement/ sealant systems into multifunctional and/or smart materials capable of self-sensing specific stimuli (i.e. stress, strain, etc.) is also shown.

“…This work continues the cycle of studies, devoted to the study of solubility diagrams in systems, containing simultaneously water-soluble nanoclusters-light fullerenols-C 60 (OH) n or C 70 (OH) m , tris-malonates C 60 and C 70 , (bis-, tris-and octo-) adducts of light fullerenes and rare earth salts (Sm 3+ , La 3+ , Gd 3+ , Y 3+ ), actinoids (UO 2 2+ , and some transi-tion and s-metals (Cu 2+ , Na + ). Here are references to articles that studied the solubility of fullerenol C 60 (OH) 24 or mixed fullerenols, based on it (for example, fullerenol-d) [1][2][3][4][5][6][7][8]. Solubility diagrams in systems with rare earth elements were quite similar: They did not form new compounds, the diagrams consisted of two branches: As a rule, long branches of crystallization of fullerenol crystal-hydrates and short branches of crystallization of rare earth salt crystal-hydrates.…”

The solubility in triple water-salt systems containing NdCl3, PrCl3, YCl3, TbCl3 chlorides, and water-soluble fullerenol C60(OH)24 at 25 °C was studied by isothermal saturation in ampoules. The analysis for the content of rare earth elements was carried out by atomic absorption spectroscopy, for the content of fullerenol—by electronic spectrophotometry. The solubility diagrams in all four ternary systems are simple eutonic, both consisting of two branches, corresponding to the crystallization of fullerenol crystal-hydrate and rare earth chloride crystal-hydrates, and containing one nonvariant point corresponding to the saturation of both solid phases. On the long branches of C60(OH)24*18H2O crystallization, a C60(OH)24 decreases by more than 2 orders of magnitude compared to the solubility of fullerenol in pure water (salting-out effect). On very short branches of crystallization of NdCl3*6H2O, PrCl3*7H2O, YCl3*6H2O, and TbCl3*6H2O, the salting-in effect is clearly observed, and the solubility of all four chlorides increases markedly. The four diagrams cannot be correctly approximated by the simple one-term Sechenov equation (SE-1), and very accurately approximated by the three-term modified Sechenov equation (SEM-3). Both equations for the calculation of nonelectrolyte solubility in electrolyte solutions (SE-1 and SEM-3 models) are obtained, using Pitzer model of virial decomposition of excess Gibbs energy of electrolyte solution. It is shown, that semi-empirical equations of SE-1 and SEM-3 models may be extended to the systems with crystallization of crystal-solvates.
