The Oil and Gas industry has been one of the engines driving economic growth globally. From the first uses of oil as both medicine and fuel for lightning up to becoming one of the main sources of power worldwide, this industry has promoted drastic increases of income to nations, states and cities that found themselves lucky enough to have reservoirs below their surfaces. Surely, due to extreme technical complexities related to exploring and producing hydrocarbons (i.e. Oil and Gas), the governments of these very often relied on private companies support, hence, sharing with such entities a fair part of the economic benefit in exchange for its services. This industry, started with the first boom in the United States during the 19th century, represents today over 2 trillion dollars across the globe – an impactful amount under any evaluation – and that should still remain as this for the next few decades. We are indeed living in a world transitioning its energy sources away from fossil fuels, bucket which contains the hydrocarbons, but its demand will not halt suddenly. The recent perspectives from the most accredited sources, including energy companies, consulting companies and environmental NGOs, points that we are close to a hydrocarbon demand peak but still far away from cutting its importance in the world energy matrix. In fact, one can expect the Oil and Gas industry to remain extremely relevant, at least, until the end of this century. The rise of renewables, as solar and wind, and the advancement of technology, as vehicles electrification and batteries improvement, will not happen uniformly across the globe and many countries currently considered emerging, as the BRICS, will still rely on hydrocarbons to feed its economic growth. Hence, evaluating the future and different aspects of this industry, as done during this work, is of key relevancy.
