There was a nice article on the Horizontal Wolfcamp published by Oil and Gas Investor magazine. It's worthwhile reading for those interested. Here is a link to the article which is located on Approach Resources website: "Horizontal Wolfcamp"
Also, Energen released their Q1 2012 results last week. Here are a couple of comments from James T. McManus, II, the company's Chairman and CEO:
"As you know there is growing excitement about the horizontal Wolfcamp and
Cline potential in the Midland Basin. We currently are participating as a
non-operated partner with Laredo in the horizontal Wolfcamp well near our
Glasscock County acreage, the early results are encouraging and we’re pleased to be getting some
data points that will help us to better assess the potential on our acreage."
"We also are closely monitoring Cline activity in the Midland Basin,
obviously, a success of either this plays on our acreage could impact our future
drilling plant in the Midland Basin."
