Drill Pipe Under-Torque: The Devil in Disguise
Brandon Chesnut, Owner/President, E&M Supply Group LLC
Many of you have been there. It’s your first large-diameter bore with your new maxi drill rig. Part of the way through your first reamer pass, you can’t seem to break out the drill pipe connections. After some careful deliberation and some unspeakable prayers, out comes the rose bud; the connection is broken. You tell yourself not to screw them together so tightly next time, but next time around is worse. The rose bud is useless – prayers get more unspeakable, and out comes the welder’s torch. It’s a nightmare; downtime, increased operating expenses and an unhappy customer are just the beginning. The connections you were able to get apart are completely mangled (or “galled), and now you have almost an entire drill string that needs to be repaired. The intense heat has permanently embrittled the threads. Repairing them will only hide the devil within. This presentation will discuss under-torque and other contributing factors, and preventive measures to help mitigate those factors.

Where’s Your Bore Going?
Danny Crumpton, New Business Development/Technical Sales, INROCK
This presentation takes an interactive look at guidance tracking systems and addresses the many questions that arise. Do I need a gyro, steering tool or walkover? Do I buy, rent or sub out the guidance? Buying can cost big dollars depending on the rig. Then you have to consider a steer hand. Renting poses other questions: Do I hire a hand, train, or contract out the hand and buy the equipment? If subbing out, who should you call, and what are their experiences and responsibilities? Do they have a good track record? Can you work with them? Do they have knowledge to back up their claims? How experienced are they?

With INROCK since 1998, he started out as a guidance engineer, and then was the guidance manager for North and South America for over 10 years. He has been involved in developing new products for the HDD industry since 1993.

Latest Generation of HDD Maxi Rigs
James Pfeiffer, Area Sales Manager-Pipeline Equipment; and Jeremy Stenslie, Chief Engineer-Cutting Tools; Herrenknecht Tunnelling Systems USA
HDD has become one of the most popular trenchless installation methods for pipeline river crossings worldwide, with distances commonly of more than 10,000 feet. Rig manufacturers are constantly improving systems to match the needs of contractors and engineers. Protecting the environment is also a key criterion. Rigs are stronger and more powerful, which is especially beneficial for intersect installations, and the use of the new HDD tooling generation like full-face hole openers and downhole jet pump systems. Smart data processing and logging systems make it easier to control the entire operation. They also enable the engineers and owners to quality control the process and use data for future references. Remote diagnosis systems reduce downtime and help operators even in remote locations to identify potential problems quickly. This presentation will review the key aspects of the latest HDD generation of maxi rigs, including an exemplary intersect installation in the U.S.

Currently he is North American sales manager for pipeline equipment at Herrenknecht, based in Stillwater, OK. He holds a bachelor’s degree in agriculture from Oklahoma State.

Jeremy Stenslie has worked for Herrenknecht Tunnelling Systems USA for 10 years. He started out working in the shop doing shipping and receiving, and is now the chief engineer of cutting tools for North and South America. He holds a bachelor’s degree in mechanical engineering from Washington State University.

Torque and Drag: Common Causes of a Preventable Problem
Larry Hereford, Operations Manager Southern US, M-I SWACO-HDD
Torque and drag are common problems in the HDD industry. Rotation gets tight, you can’t put weight on the bit or reamer, and penetration slows down. The operational risks involved are significant: stuck drill pipe or product line, twisting off, lost tooling, and the environmental risk of inadvertent returns when the hole starts getting restricted and tight. Torque and drag are just the symptoms, not the cause. Treating the symptoms won’t stop the problem from occurring. This presentation will focus on identifying the causes of torque and drag. It will discuss how to use drilling fluids to attack the cause, preventing torque and drag altogether or minimizing its impact. It will also discuss the operational, environmental and financial impact.

larry-herefordLarry Hereford has worked for M-I SWACO since 2006, managing drilling fluids and designing drilling programs on hundreds of HDD projects, from simple road bores to 11,000-ft pipeline installations. He is considered a subject matter expert on all types of water-based muds, and an expert at Schlumberger on solids control and drilling waste management for HDD and other industrial operations.
