As we come to the end of 2013, it’s a good time to reflect on some of the biggest resources stories of the year. One that immediately comes to mind is the U.S. energy resurgence and its tremendous effect on oil (NYMEX:CLF14) and gas (NYMEX:NGF14).

Only a few years ago, we were contemplating the supply constraints facing the petroleum industry, as many major oil fields around the world were declining in production. Now, with thedisruptive technology in shale oil and gas, we may be looking forward to decades of drilling.

Two charts clearly illustrate the incredible growth in oil and gas. While there are many shale areas around the U.S., there are a few notable hot beds of activity. Regarding the domestic production of tight oil, most of the growth has been in the Eagle Ford area that’s outside of San Antonio, Texas, the Bakken formation in Montana and North Dakota, and the Permian basin in West Texas.

At the beginning of 2011, the selected shale areas shown below were producing less than 1 million barrels of tight oil per day. Now, production is nearing 2.5 million barrels per day.

Shale gas in the U.S. has also taken off in recent years, with the Marcellus shale in Pennsylvania and West Virginia, Haynesville in Louisiana and Texas, and Barnett in Texas contributing to the majority of the growth, according to the U.S. Energy Information Administration (EIA). Since 2010, natural gas production among the many shale areas jumped from under 10 billion cubic feet per day to about 27 billion cubic feet per day.
