DEEP LAKE DIVE

摘要

Using just a single pull, Laney Directional Drilling has completed a 3,344m installation of 152m diameter steel gas main under one of Texas' most important strategic reservoirs. The Texas based HDD services specialist used two custom built LDD-750 drilling rigs to drill the pilot hole by the intercept method. They drilled from both the east side and the west side of the lake simultaneously until both pilot bits were in the same hole. The pilot hole assemblies were then tripped out to the west side of Lake Houston, making one continuous drill pipe string.
