Another HDD Intersect Record Set

By Jeff Griffin, Senior Editor | January 2014, Vol. 69 No. 1

“WHC did a fantastic job of keeping all the pipe on rollers as we pulled it back into the hole,” said Simon. “Pullback took 25 hours, including two hours to make pipe repairs.”

Ranger has wide experience completing long bores using the intersect method, but the procedure always is a complex undertaking.

“We were successful because of the knowledge and years of experience of Ranger’s key personnel,” said Simon. “Surveyors, drillers and our superintendents did a fantastic job, always attentive to every detail and committed to safety. There always are many things that can go wrong on these types of crossings, and completing an intersect on the first try as we did on this project is not common at all.”

For their work on the project, Simon cited contributions of superintendents Barry Nailing, James (Tiny) Matlock, Cory Baker, Steve Martin and Colt Benson, along with driller Jody Utz.
“Keys to making the successful intersect,” Simon explained, “were careful planning, including taking the initiative of performing soil sample investigations to determine the best soil layer for the intersect point, and being able to have several check coils throughout the drill path. We maintained very good hole conditions. We had a mud program designed by DCS for this drill and used two of DCS Fluid Solutions’ mud engineers during the entire project.”

Muddy geography

The geography of the location also contributed to difficulties during the course of the project.

“Rig areas on both sides had very soft and muddy conditions,” Simon said. “It was difficult to back trailers and vacuum trucks down the long, narrow board road constructed on the entry side. At the exit point, we had problems pushing out the last 120 feet of drill pipe and bit due to the very soft ground conditions on the surface. A large exit pit had to be dug with sheet pilings in order to finally get our drill bit out of the ground. Although we were near only rural roadways, traffic control was needed due to the quantity of vacuum trucks and pipe trailers that were required.”

A Quanta Services company, Ranger was established in 1993 and specializes in horizontal directional drilling installations beneath waterways, congested areas, highways and environmentally sensitive areas. In addition to directional drilling, Ranger employs a broad range of construction methods. Ranger crews have successfully completed projects in some of the most difficult geological conditions in the United States.
