Many things go into getting the most life out of your mud pump and its components — all important to extend the usage of this vital piece of equipment on an HDD jobsite. Some of the most important key points are here. The long and the short of it is to use clean drilling fluid and you will extend the life of your pumps expendables and downhole tooling, and keep up with your maintenance on the gear end of your pump. Avoid pump cavitation at all times. Read More

18. Drilling Fluids Critical to Successful HDD Jobs

Times have changed, and contractors now realize the importance of drilling mud

Jim Watland has been working in the horizontal directional drilling (HDD) industry for 26 years. But he acknowledges that it wasn’t until several years ago that he realized the importance of drilling fluids.

After “learning the hard way,” as he puts it, drilling mostly with water and occasionally a bit of polymer mixed in, he’s adopted modern drilling fluid practices. The results are night and day for the 15 HDD crews he oversees. Read More

16. Cobbles and Boulders: No Problem!

KS Energy Services recently completed a project that combined a rough and inconsistent terrain with subzero temperatures, two factors that made this project a challenge for the contractor. The project — which consisted of five crossings over 8,200-plus ft — took place in Janesville, Wisconsin, and involved relocating a steel natural gas pipe due to bridge repair work to the I-39 corridor. This project marked the first foray for KS Energy into the maxi drill HDD market and purchased a Prime Drilling 500,000-lb rig to handle the second of the five crossings. Read More

15. Trenchless Shines on Daunting Underground Overhaul Project in Halifax

Halifax Water, no stranger to cured-in-place pipe (CIPP) renewal projects, completed a successful pilot project along approximately 460 m of the easiest to access portion of Northwest Arm Trunk Sewer to test the feasibility of using CIPP on this large diameter trunk sewer. Halifax Water knew that trenchless was the best alternative, given the narrow linear easement and the location of the pipe a stone’s throw from the water’s edge. Of the $23 million, approximately $18.5 million was the trenchless renewal portion — including cleaning, assessment and post-installation inspections. Read More

13. Avoiding a Deep Freeze: Tips for Horizontal Directional Drilling in Winter

Sitting at my desk and looking at the beautiful fall colors out my window, I can only think of one thing: “When will the first snow fly?” Being a permanent resident of the great white north, this is inevitable. For the horizontal directional drilling (HDD) industry, it signals higher labor costs, lower production rates, frozen fingers, toes, hoses, pumps and a boon to the -40C windshield washer fluid industry. Knowing that you will be sending drilling crews out in this weather, being prepared is key to keeping the drill turning. Keeping a careful eye on the temperatures at this time of year is a priority.

12. A Brief History of Directional Drilling: The Birth and Development of the HDD Market

Martin Cherrington does not have a Wikipedia page explaining how he is an inventor of the original equipment and process that eventually revolutionized an entire facet of construction. But when trying to encompass the history of horizontal directional drilling, it’s only appropriate to start with the man who many veterans of the trade have come to recognize as the father of HDD. Horizontal directional drilling is an idea Cherrington first conjured up in the early 1960s when he was working for a utility installation company in Los Angeles. Read More

11. Rock Solid — Or Is It?

When you are told something is “solid as a rock,” that’s usually a good thing, understanding that you will know whatever that something is, that it will last. For a horizontal directional driller, that phrase takes on a whole other meaning, usually leading to a lot of questions. What kind of rock is it? What’s its psi? Is it layered with multiple rock formations? Whether it’s sandstone, cobble, gneiss, limestone or boulders, all these questions (and many more) are critical to the contractor successfully completing a bore on time and on budget. Read More
