Shale gas revolution: helping to ensure global energy security

For 150 years, the modern oil industry has mainly developed high-abundance oil and gas enriched in reservoirs, namely conventional oil and gas. It has long been known that these oil and gas are formed and discharged from dark organic-rich shale-like strata, but there is still a considerable portion of oil and gas residues in the shale. Due to its low abundance and poor technical level, it has been difficult to develop economically. At present, the global proven shale gas reserves are 456 trillion cubic meters, mainly distributed in North America, Central Asia and other regions.

With the maturity of horizontal wells and fracturing as the core technology, and the significant cost reduction, shale gas has achieved large-scale development in the United States, and its natural gas production has been transformed from a decline of more than 30 years to a rapid growth. And in 2011 achieved an annual growth of 7.8%, with a production of 651.3 billion cubic meters. Data show that by 2012, shale gas production has accounted for 37% of the nation's natural gas supply. The International Energy Agency predicts that the United States will surpass Russia in 2015 to become the world's largest natural gas producer.

The surge in production has reduced US natural gas prices to around one-fifth. At the same time, the United States has also changed the status of imported natural gas in the past and began to consider export. The low gas price, in turn, caused producers to turn their rigs to their associated or symbiotic shale oil. As a result, US oil production fell to rise after 2008, and in the following three years, the annual growth rate reached 4.9%, becoming the world in the same period. Countries with the largest increase in oil production. By June 2012, US shale oil production reached 720,000 barrels per day (about 36 million tons per year), a year-on-year increase of 12.5%. The shale gas revolution has enabled the United States to see the dawn of energy independence. Many institutions are optimistic that around 2035, the United States will not only achieve net exports of natural gas, but also the dependence on foreign oil.

The success of shale gas development has raised people's understanding of various unconventional oil and gas potentials, not only ensuring the prospect of sustainable oil and gas development, but also promoting the renewal of petroleum geological basic theory and the rapid development of oil and gas exploration methods and technologies. People call it a quiet revolution. This revolutionary development from technological innovation shocked the world and changed the pattern of energy. From a vertical perspective, it improves the energy composition, and the relatively low-carbon oil and gas replaces the high-carbon energy, creating conditions for the transition to non-fossil energy; from a horizontal perspective, it promotes the transformation of oil and gas production to a more balanced multi-source supply, which is conducive to safeguarding Global energy security.
