A type of low-carbon energy source with abundant reserves and a high calorific value is natural gas. Compared to coal and oil, it is cleaner and more effective. One of the key strategies to lower carbon emissions worldwide is to increase the use of natural gas. The need for energy on a global scale has been rising recently. The energy recovered from conventional, renewable, or nuclear sources cannot, however, keep up with the enormous rise in demand for energy. Natural gas hydrate deposits, which are present all over the world, are a reliable supply of natural gas. Since they were originally discovered in the 1960s, natural gas hydrate deposits have been hailed as the most diversified source of energy, holding significantly more energy than both conventional and unconventional resources combined. In this chapter, various technologies to predict (geologic sampling and drilling, seismic prospecting, geochemical detection, and well logging) and extract (thermal properties, depressurization, chemical inhibitor injection, and gas displacement methods) natural gas from permafrost and oceanic natural hydrates are studied.
