Baker Hughes Incorporated –
Frac-Hook™ Multilateral System
Producing gas in tight shale formations often
requires major pumping investments.
Traditionally, a driller did not have many good
choices when fracturing a tight gas well. One
option was to simply pump frac fluid into the
open hole and hope for the best, which resulted
in frac fluid flowing mainly to the area of least
