Unconventional Hydrocarbon Resources

The world energy demand is increasing rapidly with consumption of 100 million barrels of oil per day. The modern world is trying to shift towards cleaner energy, including renewable energy sources, however, the fossil fuel demand continues to increase due to its immense uses in everyday life as well as in all industry sectors. Petroleum products ranging from toothpaste to smartphone, transportation, etc. are part of modern life. The different countries are using different energy mix, including oil, natural gas, coal, hydroelectricity, nuclear, solar, tidal, wind, and many more. Despite many energy sources, gap between the energy demand and supply is increasing day by day due to increasing human population. The term ¿unconventional resources¿ refers to the hydrocarbon deposits requires improving technologies to develop at a commercial scale, for example: unconventional resources are shale gas, shale oil, tight oil, tight gas, heavy oil, shales, gas hydrates, and coalbed methane. Unlike the conventional reservoirs, the unconventional reservoirs are huge in volume but there are lot of challenges to explore those resources.
