An oil revolution is taking place in the US West and Mid-Continent
While the blockbuster plays in states such as Texas and North Dakota make the biggest headlines for increases in US crude oil production, there's no denying that developments in other states together add up to significant gains. Just like the other plays, many of these involved the technological advances of horizontal drilling and multi-stage hydraulic fracturing. The US map shown here indicates how widespread horizontal drilling has become.
Oil statesAfter North Dakota and Texas, there is a significant tier of states where crude oil production is increasing on a steady basis (See Figure 1). Six states in the western half of the US combined have increased US oil production by about 240,000 barrels per day (b/d) since early 2007. These include:
- Oklahoma – Crude oil production has risen about 70,000 b/d from January 2007 through February 2012 (the latest available from the Energy Information Administration).
- Colorado and New Mexico – Each saw increases of about 50,000 b/d over that period.
- Utah and Kansas – Each had 30,000 b/d increases.
- Wyoming – While Wyoming's net gain over the period was just 10,000 b/d, the state has seen a steady increase of twice that figure since bottoming out in mid-2009.
