Handling of drilling mud on the project site has increasingly become a critical issue from an environmental standpoint. This issue of Trenchless Technology takes a close look at mud use, recycling and disposal. The principal drilling mud manufacturers include Baroid Industrial Drilling Fluids, CETCO, Wyo-Ben, and M-I Swaco. Each one of these companies will tell you that drilling fluids are critical for these reasons: creating borehole stability, suspending cuttings or spoils and carrying the spoils out of the borehole. The bottom line is you cannot have a successful HDD, auger boring, or microtunneling project without the use of drilling fluids. Excessive drilling fluids that come to the surface are referred to as "inadvertent returns." This has been the subject of most of the boring contractor meetings in the last couple of years. The constant concern is the reaction to these returns from the state and federal environmental agency officials. Considering all of these environmental concerns, one would think that drilling mud is really bad stuff. But, I would like to point out that drilling mud (bentonite clay) is used in many products that we use personally every day. For example, it is in toothpaste, laxatives, facial cream, fruit juices, ointments, and it is used as a clarifying agent in wine and vinegar. When you consider these examples, it is surprising there is so much environmental emphasis on properly handling drilling muds. As you will see in reading this issue's cover story, disposing of drilling fluids can be quite costly for a project. Thus, in recent years mud recycling systems have gained greater importance. So be sure to read this article and develop your own opinion on drilling fluids. NASTT's 2019 No-Dig Show This year 's NASTT No-Dig Show is being held in Chicago, March 17-21. The venue is the Donald E. Stephens Convention Center in Rosemont, just outside of Chicago, which is close to Chicago's O'Hare Airport. I have been at the Donald E. Stephens Convention Center; and it is a nice and accessible facility. Chicago is so convenient to all of North America that attendance is looking to be very strong. The show will kick off with an exciting breakfast on Monday, March 18, with motivational speaker Jody Urquhart. The NASTT Educational Fund Auction that evening will feature a reception and large silent auction. Of course, the exhibit hall opens Monday, March 18, and there are more than 160 technical presentations during the show. Tuesday, March 19, continues with more exhibit time and technical presentations. Plus, there is the annual Gala Awards Reception & Banquet Dinner that evening. Wednesday continues with some of the same great technical sessions and more exhibit hall hours. The show closes out with a rousing luncheon on March 20. Please don't forget these major aspects of the show: 1. Presentation of the 2018 Trenchless Technology Projects of the Year at the Kick-Off Breakfast 2. Presentation of the 2019 Trenchless Technology Person of the Year at the Kick-Off Breakfast 3. Chairman's awards presented at the Gala Awards Reception & Banquet Dinner 4. Special forums Monday and Tuesday on Direct Pipe, Advanced Pressure Pipeline Condition Assessment and Innovative Products. Please check the show website at nodigshow.com for details regarding the agenda. Importantly, be sure to register before Feb. 8 to take advantage of the early bird registration discount of $100. Great trenchless success in 2019, Bernard P. Krzys Publisher BY B E R N A R D P. K R Z Y S D R I L L I N G M U D
