For the week ending March 23, 2012, U.S.working rigs declined by 16. The majority of these were gas drilling rigs (-11), versus oil (-4).
From the graph to the right, you can see the trend in gas rigs dropping off as persistently low natural gas prices has made drilling for dry gas uneconomical in most plays. Oil rigs now make up 2/3 of working U.S. rigs. This time of year, last year, oil rigs didn't even make up half.
YoY oil rigs are up 54%, while gas rigs are down 25%.
Major State Variances
We can see operators shifting rigs to more oily regions, like the Bakken and Eagle Ford, and out of gassy plays like in the Barnett and Haynesville.
This is putting pressure on margins of drilling service companies.
