Concrete structures repair results in substantial economic and environmental issues. So, new technologies able to increase concrete lifetime are being developed. Among them, the self-healing mechanisms, which can be improved by using polymers. Thus, three different materials are synthesized to act as self-healing systems. They are: (I) cross-linked gelatin mixed with CaCO 3 (the self-healing agent); (II) a core-shell system based on the material I layered by poly(hydroxypropyl methacrylate); and (III) a second core-shell structure based on the material I covered with poly(vinyl alcohol). Cross-linking and grafting are performed using glutaraldehyde. Fourier-transform infrared spectroscopy (FTIR) proves the structure obtaining. Thermogravimetric analysis and differential scanning calorimetry prove that the materials show thermal properties that allow their use in concrete applications. Swelling degree shows that all materials swell when in contact with water. Granulometry shows the materials are mostly in the millimeter scale. Last, an aqueous media release test shows that the three tested systems did not liberate significant amounts of CaCO 3 . Therefore, both the gelatin and gelatin + polymer systems can protect the healing material, avoiding the release of the self-healing agent before the concrete cracking takes place.

“…Mainly for applications focused on infrastructure, underwater materials, and construction in general. [ 55–58 ] Thus, this single procedure for the preparation of a self‐healing agent is very auspicious, mainly because it allows to obtain quickly, efficiently and affordably, self‐healing materials that can significantly improve the living conditions of the neediest populations, especially in countries developing countries, where the saving of resources must always be pursued.…”

Insofar the cost of repairing concrete structures reaches the trillions of dollars, new technologies, such as concrete self-healing, are investigated continuously. Consequently, the main objective of this work is on the production of a cheap and easy-to-make material, which can be used in large-scale applications, besides presenting similar results as other ones more complex systems. In brief, a core-shell system is produced and investigated as a self-healing agent. Aiming this, a mix of gelatin and sodium silicate (Na 2 SiO 3 ) is used as the core, while poly(vinyl alcohol) (PVA) is the glutaraldehyde crosslinked shell. The obtained materials are characterized using several techniques, such as Fourier transform infrared spectroscopy (FTIR), as well as, thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). FTIR proves the obtaining of the proposed system. In turn, TGA and DSC showed that the material could endure real-life applications. Also, granulometry tests show that the obtained materials are mostly in the micrometric scale. The Na 2 SiO 3 release is especially tested in aqueous media, proving the core-shell system swells, releasing its active agent. Thereby, the obtained results allow concluding that the presented core-shell material is useful to the self-healing applications.

“…The work of Noshi, et al (2018) and Noshi et al (2019) made an excellent attempt using machine learning and data analytics to identify possible factors that may have been responsible for casing failure. They employ artificial neural network (ANN) and python coding, descriptive and predictive analytic to process casing failure in Granite Wash Play of Western Anadarko basin.…”

This paper focus on factors attributing to casing failure, their failure mechanism and the resulting failure mode. The casing is a critical component in a well and the main mechanical structural barrier element that provide conduits and avenue for oil and gas production over the well lifecycle and beyond. The casings are normally subjected to material degradation, varying local loads, induced stresses during stimulation, natural fractures, slip and shear during their installation and operation leading to different kinds of casing failure modes. The review paper also covers recent developments in casing integrity assessment techniques and their respective limitations.The taxonomy of the major causes and cases of casing failure in different well types is covered. In addition, an overview of casing trend utilisation and failure mix by grades is provided. The trend of casing utilisation in different wells examined show deep-water and shale gas horizontal wells employing higher tensile grades (P110 & Q125) due to their characteristics. Additionally, this review presents casing failure mixed by grades, with P110 recording the highest failure cases owing to its stiffness, high application in injection wells, shale gas, deep-water and high temperature and high temperature (HPHT) wells with high failure probability. A summary of existing tools used for the assessment of well integrity issues and their respective limitations is provided and conclusions drawn.
