RBN Energy: the science behind shale exploration; Apache, CLR in the Anadarko -- a very nice article covering a lot of bases, including an update on the Kansas and Oklahoma Anadarko, the science behind the exploration, and an overview of some of the more prominent operators in the Anadarko --

The Anadarko basin is similar to the Permian Basin in that it contains multiple layers of oil-bearing formations that can be exploited by drilling at different depths  The Anadarko is not a “new” oil and gas basin but has already been extensively and successfully exploited for decades using conventional vertical drilling technology. Apache and other producers are now exploiting these proven assets using new horizontal drilling and hydraulic fracturing technology. But the effort is directed towards extracting known resources at the least cost in a systematic manner.
