Horizontal drilling, I know for certain, has been going on for the last 15 years.
Not only am I in the industry, but I have leases in the Barnett Shale that incorporate horizontal drilling.
Fracking and horizontal drilling do not necessarily go hand in hand. They can, yes, but horizontal drilling is to fracking like cake is to frosting...a good cake needs no frosting, but a good cake is improved by frosting.....m
Hydraulic Fracturing and Steerable horizontal drilling have combined to make production from tight formations like the shale plays of Bakken, Eagle Ford, Permian Basin and several other economic to produce. Without the combination, not enough oil is produced to make significant economic investment in these plays.
