Significant CO2 concentration increases are predicted to contribute greatly to long-term global warming and related climatic instability, resulting in unforeseeable natural disasters, glacier melting, and extreme weather patterns. These difficulties may be solved by successfully collecting CO2 in order to achieve a cost-effective and environmentally sustainable balance between CO2 emissions and utilization. Due to the absence of a current evaluation of state-of-the-art advances in projected carbon utilization methods, it is vital to present an accurate and timely explanation that demonstrates a thorough comprehension of such sophisticated techniques. Given the critical role of carbon consumption in carbon management, it is necessary to analyse the overall picture. To overcome this gap, our study will investigate the benefits of CO2 recycling in a number of industrial processes, including enhanced oil recovery (EOR), fuel and chemical conversion, mineralization, and biological conversion. The objective of this study is to integrate current research in carbon management through analysis of its application in areas and methodologies such as increased petroleum recovery, CO2 conversion to value-added fuels and chemicals, mineralization and biological conversion to value-added products.

While performing various steps for exploration and exploitation of geothermal resources, the applications of geochemical methods are pivotal for reservoir characteristics evaluation. It is used concurrently with geological and hydro-geological appraisals to supplement available information regarding the prospectively of the region of investigation at the relatively low cost compared to geophysical methods or drilling. Temperature range of 40 °C to 47 °C is demonstrated by the study area comprising of several thermal water manifestations. Studies from existing wells and surveys have suggested the presence of a sizable low enthalpy geothermal resource in the field. One of the most prominent uses of geochemical sampling is the determination of subsurface temperatures using Geothermometry. In this study, commonly accepted concepts of cationic and Silica Geothermometry have been applied to understand conditions in the reservoir. Interpretation of the data has given us some input on the reservoir characteristics like reservoir temperature, mixing process and multiple fluid origins. In Dholera geothermal field for determination of variation in hydrochemical facies and understanding of the advancement of the hydrochemical forms, the current research additionally imagines the significance of graphical portrayals like Piper chart, Scholler and so forth individually. The seawater intrudes the composition of water shows the reservoir. The physio-chemical properties of the water also influence exploitation strategies.

Abstract Due to soaring demand for universal energy, industry forced to look forward in either expand the limit of conventional energy resources or to look at other possibilities such as renewable energy resources and unconventional hydrocarbon resources. The challenges might be figured out by revolutionary technological developments in the energy sector by science and technology. The industry needs splendid technological breakthroughs in the energy sector to push the final frontier of conventional energy resources. Owing to its superior particle size and properties, nanotechnology can likely of moving far that current energy supply by introducing new technologies. The exact exploitation and manipulation of matter at measurements of (1–100) nanometres have revolutionized many sectors, including the petroleum sector. The upgrade in nanoscale organized materials represents one of the fascinating, inventive viewpoints bringing innovative advances in numerous industries. The charge of oil extraction is under heavyweight, and it becomes increasingly difficult to legitimize it when the gross price of oil is powerless and depressing. There is a universal belief that nanotechnologies can be to produce new, more valuable nanomaterials to oppose these technological limitations. Many research endeavours are being coordinated towards the opening of immense and diverse advantages of nanotechnology in the oil and gas industry. The research experts have experienced the utilization of different nanoparticle types and sizes. Nanoparticles show exceptional properties because of their large surface area and highly activated particle surface. The nanotechnology can be performed at a different scale in petroleum engineering from exploration, drilling, cementing, reservoir, completion, production, and processing and refinery in each stage. This paper intends to give a concise thought of the significant uses of nanoparticles, their potential advantages, associated economic and technical challenges, and solutions.
