Petroleum stocks bounced back with a moderate rise – April 28

In the recent Energy Information Administration petroleum report, there is an analysis of the shift in the US oil production that has been rising for the past couple of years, after it had been declining in the last couple of decades. In 2009 the oil production increase was mainly due to the deepwater development in the Golf of Mexico, while the 2010 increase is mostly due to the rise in horizontal drilling programs and other shale formations.

Here is a summary of the EIA petroleum report about crude oil price and petroleum stocks for the week ending April 22nd:

Part of this rise is due to the increase in U.S. Ending Stocks of Crude oil by 0.57% or 6.1 million barrels– reaching 1,089.6 million barrels.
