Tight oil "is coming"

"Shale gas revolution" wave has not in the past, "tight oil revolution" concept and wind and sky. April 30 this year, the International Energy Agency (IEA) in Paris, France held the IEA World Energy Outlook 2013 oil seminar theme is "tight oil revolution in the future." "Tight oil" is a new cutting-edge concept, but its essence is the original of several  unconventional gas  types collectively. IEA for "tight oil" is defined is: "Use of horizontal drilling and multi-stage hydraulic fracturing from shale or other low-permeability oil reservoirs mined." In recent years, along with the massive success of the North American tight oil extraction such previously neglected unconventional oil resources have become involved in the national oil industry competing hot area. United States: "tight oil revolution" as an important pioneer in energy, tight oil exploration and development in the United States and Canada, was a huge success, and its production has increased dramatically reversed the downward trend in oil production region. From 2008 onwards, the U.S. domestic oil production increased production mainly from tight oil.frac proppant Tight oil production rapid growth drivers since 2008 in the application of unconventional drilling technology and reservoir fracturing technology continues to progress and improvement. In 2011, U.S. oil production for the first time directional wells over gas production, the number of horizontal wells over vertical wells. Ceramic proppant2015 U.S. tight oil reached 75 million tons annual output in 2020 reached 150 million tons, accounting for domestic oil production 1/3. Tight oil revolution for the United States to bring positive impact is far more ease domestic oil supply and demand, more far-reaching political implications is the release of U.S. energy security and geopolitical pressures. In recent years, the U.S. dependence on foreign oil has dropped to 45% from 63%, the Middle East oil imports by the U.S. line gradually marginalized. This is the IEA as well as paying attention to all the countries worldwide shale oil of the important reasons.
