7 AUGUST 2021 WorldWide Drilling Resource® Industry Announcements Numa introduced a new range of Casing Ring Bit Systems for simultaneously drilling and casing vertical or horizontal holes in piling, foundation, anchoring, geothermal, and other casing applications. It is a complementary product to Numa’s highly successful Super Jaws® Overburden Bits and Impact Ring Bit Systems®. This Casing Ring Bit System consists of a pilot bit, casing shoe, and heavy-duty ring bit and is available in a wide range of sizes for drilling holes 16-48 inches in diameter. The design is highly configurable with options for both drill-through and nondrill-through applications requiring the installation of casing into bedrock. The system also boasts the ability to handle overburden and/or hard rock conditions using either conventional or reverse circulation DTH hammers. Some of the many benefits of Numa’s Casing Ring Bit Systems include: jReduces cost with same pilot bit used with multiple ring sizes jCleans holes efficiently through large flushing slots jAble to be used in vertical and horizontal applications jEliminates carbide issues locking into pilot jProvides simple lock design to better engage and disengage from ring “We are pleased to announce the addition of Numa’s Casing Ring Bit Systems to our product line,’” said Numa President Ralph Leonard. “This advancement is yet another example of Numa’s rock-solid reputation for designing dependable drilling products that deliver in mission-critical, harsh applications.” Deep Foundations Instituteannounced the winner of the 2021 DFI Outstanding Project Award as the team of Stantec - engineer; Ames Construction - general contractor; Case-Bencor JV (Keller) - foundation; Missouri River Energy Services - owner; Rembco Geotechnical Contractors - grouting; and Schnabel Geostructural Design & Construction - anchor. The team is being recognized for the ingenuity of their design in modifying Red Rock Dam on the Des Moines River in Iowa into a hydroelectric facility. Among the geotechnical and other challenges the Red Rock team overcame was constructing a new intake channel, penstocks that carry water to the turbines, and a power house directly adjacent to the existing dam’s spillway. To maintain the dam’s integrity during construction, extensive water- and earth-retention systems, prescriptive construction staging, and a robust dam safety surveillance program were used. The U.S. Army Corps of Engineers’ facility near Pella, Iowa, now provides up to 55 megawatts of clean, reliable power to surrounding communities. The key foundation elements and excavation features included diaphragm walls, deep excavations, and treatment of solutioned gypsum deposits. Environmental Monitoring by Thomas Kwader, Ph.D., P.G. Owner, Qwater Well Developer and WorldWide Drilling Resource® Hydrogeologist Beware - Local Governments Banning Private Domestic Wells I have worked as a professional hydrogeologist for more than 45 years. I have been involved in developing large-scale water supply systems, cleanups of contaminated groundwater, the design of numerous wells, and have been a proponent for the protection of groundwater. One of the most upsetting and illogical political policies of late is various governmental authorities prohibiting private homeowners from drilling private wells on their own property for personal use and consumption. The underlying reason for “outlawing” these private wells is so water supply authorities can force all users to hook up to their water supply systems, forcing the private homeowner to pay for and maintain the authorities’ water systems based on their personal consumption. These supply systems are awfully expensive to install and require the costs passed down to the consumers to pay for the capital cost of the systems. It is difficult for the governmental agency to argue the required is for the “protection of the groundwater resources” as large-diameter production wells may actually be detrimental to the groundwater and surface water resources. In some cases, local residents were unaware these rules were passed without a “vote” or ample advertising of the proposed rule outlawing new private wells. Although advertising of these proposed rules may be required in local newspapers, some are buried, published in holiday editions, use small print, and take advantage of the fact many people no longer receive print media. So the notices go virtually unnoticed until in effect. We, as members of the well drilling and groundwater communities, need to be aware and speak up if we become aware of self-serving actions against the rights of homeowners to drill and use natural groundwater. Contact your local well drilling and groundwater associations immediately if you become aware of proposed laws or rules to restrict the use of private wells.

8 AUGUST 2021 WorldWide Drilling Resource® by Tim Rasmussen The old Stadeli 22W rig was sitting in the road with a broken frame . . . In the morning, they met at the shop and talked about what they had to do to fix the broken frame of the truck the rig was mounted on. It was obvious they needed to jack up the truck, get it somewhat straight, make some temporary repairs, then try and make it to the highway and to town. Edgar said there was a good mechanic in San Luis he knew and that he would try to get him to come out, give advice, and help them. The men began gathering the tools they might need. Four large screw jacks and the hydraulic shop jack, various pieces of steel, some large tow straps, the cutting torch, and various wrenches, bolts, and anything else they could think of they might need. They put all of it in two of the pickups and headed out to the rig truck. One the way, Edgar stopped and picked up Neldo, a 70-year-old man from San Luis who owns a heavy truck repair shop. He is a skillful mechanic with a lot of experience. He also had a few pieces of truck frame they put in the pickup. When they got to the truck, they talked it over again and Neldo agreed with the plan. They carefully jacked up the truck until it began to look level. They decided to patch the cracked frame member. They did not want to weld on it much, so they fashioned a patch from one of the frame pieces they brought, cut holes with the cutting torch, and bolted it back together as best they could. By the time they finished it was dark again, so they slowly and carefully drove the truck a few feet at a time to a more level spot about 50 feet away where they could get off the road a little. They secured the truck and went back home. The next morning, they drove back to the truck, examined it carefully, then drove gingerly to the highway. Once on the smooth road, they had no problems making it to Neldo’s shop. They left it there. Neldo lifted the rig off the truck, replaced the frame from behind the cab back, replaced the rig onto the new truck frame, and got the truck back on the road and ready for work. The total cost of the repair was about $1500 USD.

11 AUGUST 2021 WorldWide Drilling Resource® The Difference Between Safety Helmets and Hard Hats by Nicole Baker, Sales and Customer Training Manager, HexArmor® Head protection is a big deal on the job, but when given two choices - a safety helmet or a hard hat - what should you reach for? Hard hats are more commonly known to workers and have been around for over 40 years. Over the past four or five years, the traditional design has transitioned to a safety helmet. This is good news as the safety helmet brings much-needed upgrades - including better protection and fit - to one of the most used PPE (personal protective equipment) pieces on the job. The concept behind this kind of head protection isn’t new; it’s been around for years in the sporting world. In fact, the same protection methods used in mountain climbing, biking, and other sports have been worked into the safety helmet design, with some featuring better side impact protection and a more secure and ergonomic fit for the wearer’s head. These upgrades offer better functionality and comfort for head protection used on the job just like it does for sport-lovers and athletes. How to select the proper safety helmet. First, remember, the purpose of head protection in any safety program is to mitigate and/or eliminate hazards and exposure to injury while on the job. Being at risk for a head injury is dependent on your work environment and its associated hazards. Oftentimes, workers must wear protection even when there is no apparent sign of danger. So, when choosing your head protection, take time to understand exactly what you need. Start by referencing OSHA (Occupational Safety and Health Administration) regulations for your industry to understand the type of head protection required. Is work being done at extreme temperatures, around electrical hazards, or at-height? These answers will point you in the right direction. Lastly, ensure the head protection you choose meets the ANSI Z89.1 standard for OSHA compliance. Additional factors should also be considered. The suspension system is a critical piece of the safety helmet; does the safety helmet fit properly and feel comfortable? Do you require use of accessories, such as hearing protection, face shields, or respiratory equipment? If so, make sure they are compatible with the safety helmet. Depending on the manufacturer, you can find protective options with new and improved technology to help increase performance and comfort on the job, such as a 6-point suspension system, permanent antifog face shields, and memory foam earmuffs. Any further questions regarding how to properly select the right safety helmet for you can be answered by a safety helmet manufacturer who is experienced in helping companies find their ideal safety solution.

12 AUGUST 2021 WorldWide Drilling Resource® Horizontal Directional Drilling by Ronald B. Peterson Drilling Products Specialist, Mountainland Supply Company I would like to be able to never make a mistake, but unfortunately I am not. There is no way to sugarcoat it and make it any more palatable. In my WWDRJune 2021 article Artesian Flows, I reversed the numbers on pressure per foot of hydrostatic head. The correct relationship is 2.31 feet of head equals 1 psi of pressure. I apologize for the error. To complete the correction of the error, 3 feet of head would be 1.3 psi. At 50 feet, it becomes .026 psi per foot. You would need to raise the drilling fluid (mud) weight to 8.8 pounds per gallon to control that pressure of artesian flow. However, the increase of the fluid weight as a result of solids entrainment in the mud while drilling would more than likely accomplish your goal and make any further action unnecessary. Thanks Britt, Don, and David for letting me know about my mistake. I apologize to you all for any confusion this may have caused. Increase of drilling fluid weight as a result of drilling operations will control most minor artesian situations. Every situation is different and may have more than one potential solution. Always act quickly, evaluate the situation, and use the solution that is the most effective, the fastest, and the least expensive. Now that’s out of the way, let’s get on with this month’s discussion “Horizontal Directional Drilling.” Horizontal directional drilling (HDD) is still advancing a hole in the ground; however, the hole is horizontal instead of vertical. The fluid properties and the testing procedures are the same in horizontal drilling as in vertical drilling. Calcium or hardness and pH are still critical to know and adjust for. Filtrate or water loss and filter cake are still critical properties. The test procedures are basically the same, but the desired properties are different. Assuming we have good makeup water because we have tested and verified it, we need to use soda ash to adjust the calcium content and raise the pH as necessary. We then need a bentonite product designed with properties for horizontal boring. We need polymers to achieve desirable filtration control properties and stabilize active formation clays and shales. In very fragile formations, we may also need a lost circulation control material. Viscosity is still resistance to flow or a measurement of the thickness of the fluid, and can be a necessary evil. In vertical drilling, hole cleaning is achieved through velocity. If the velocity is insufficient, we simply raise the viscosity. When the solids-laden fluid reaches the surface, we want the solids to settle out in the pits. If the solids settle out in the pits, won’t they also settle out in a horizontal borehole? If you raise the viscosity to correct this situation it can be counterproductive. We know viscosity is resistance to flow, and we are trying to maintain flow. We are also very close to the surface, so the ground is very fragile. High-viscosity fluid plus high solids content results in reduced flowability. Reduced flowability means more pressure will be required to move the slurry. High viscosity causes high circulating pressures. High circulating pressures tend to break things and cause frac-outs and/or humps in streets, highways, and driveways. This is never good. We need to carry the cuttings by building different properties related to viscosity. These properties are yield point and gel strengths. Different bentonite products have different properties because they are designed for different drilling disciplines. Rather than depending on settling of solids in the pits to clean the drilling fluid, we now depend on solids removal equipment. Suspension is critical in HDD. Any recirculated solids need to be kept in suspension while in the borehole so they do not settle out and close off the bore. High solids content will cause additional wear on all of the circulating system components. If the borehole is deep enough and there is formation fluid present, there may be a need to be concerned with hydrostatic head. Very rarely, if ever, is a higher fluid density at the pump suction necessary in a horizontal borehole head. If higher hydrostatic head is needed, use properly designed weighting agents to achieve it. Remember, high-density fluids also require more pressure to flow. Gels are the tendency of the fluid to set up when idle. They need to be able to become fluid again when disturbed. This ability is referred to as fragile gels. The buildup of solids is not as much of a problem in a sacrificial fluid system, but it may be a major problem if recirculating or recycling the fluid. Sand content is every bit as critical in a horizontal borehole as in a vertical borehole for the same reasons. Remember, equivalent circulating density (ECD) is a combination of the hydrostatic head and the pressure required to move the fluid. Fracture gradient is the pressure at which the circulating pressure exceeds the strength of the formation. If the ECD exceeds the fracture gradient, you will have a frac-out or inadvertent flow to the surface, or into a stream, and/or an undesirable hump in an inconvenient location. Gels and viscosity, while related properties, are not the same. A thick fluid may not suspend cuttings, but a thin fluid can be designed to suspend cuttings. In horizontal drilling, flowability is the major concern. There is a popular statement that at the end of the bore if the fluid will flow, the product will go. We have only briefly scratched the surface on HDD fluids. If you have any questions on horizontal directional drilling fluids or if you have another topic you would like addressed, please contact Michele (below) and she will get your question to me.

14 AUGUST 2021 WorldWide Drilling Resource® Ant Behavior Improves Horizontal Directional Drilling Design Compiled by the Editorial Staff of WorldWide Drilling Resource® Trenchless technology has increased in demand due to the need for utility conveyance under multiple obstacles, such as highways, waterways, railroads, and other manmade or natural structures, as well as quicker and less invasive methods of installation, one of which is horizontal directional drilling (HDD). Engineering a successful HDD project requires calculations, analysis, and evaluation of feasibility, design, budget, and risk. Because the subsurface is unseen, it poses a set of challenges to underground infrastructure design. Subsurface investigations are performed to determine the underlying geology, and this is dependent on the type of infrastructure to be installed. Thanks to the lowly ant, optimization of HDD has become a more informed, efficient process. Some of today’s optimization techniques to streamline the decision-making process during HDD design involve a look at ant colonies and how they “learn” the best pathway to a food source. Analysis of a colony of ants, a swarm population, reveals a remarkable collective intelligence. Developed as one of the artificial intelligence (AI) disciplines, swarm intelligence (SI) derived inspiration from studying the collective behavior of insects and animals. In Ant Colony Optimization (ACO), the ant searches for food in a random manner until the food source is found. Returning to the colony, the ant leaves a pheromone (a chemical ants produce) trail based on the quality and quantity of food. The colony eventually responds to the strongest presence of pheromones leading to the food, which is usually the shortest, most advantageous route. As English Writer Richard Jefferies said, “It would seem that the ant works its way tentatively, and observing where it fails, tries another place and succeeds.” ACO, a step-by-step computational procedure within SI, is a technique using probabilities for finding optimal paths based on collection information. In application, multiple operations considering several variables are run to determine the optimal drill path, similar to how ants communicate pheromone signals repetitively to the whole colony. Real data from HDD projects help implement ACO. Actions of expert HDD professionals, mechanics of drilling simulations, historical data from drilling logs, and simulation data are used to generate decisions resulting in efficient drilling. The drill path is optimized by continuous ACO implementations, setting the depth of the alignment and its entry and exit angles as the design parameters. This ensures a minimal, less costly drill path and avoids collapses or instability. As an advanced tool providing more rapid feasibility and analysis of HDD projects, ACO results in more rigorous designs and ultimately, lower cost and risk. DIR

This new law includes a national strategy for landslide hazards, risk reduction, and response, including landslide hazard stabilization. There are several methods for slope stabilization to mitigate landslides, one of which is soil nailing. Soil nails transfer tension and compression loads and are passive anchoring components without free length and prestressing. These structural elements are used for reinforcing the ground/rock mass to stabilize slopes and reduce the chances of landslides. Each soil nail consists of a high-strength steel bar inserted deep into the slope in a drilled borehole. A highstrength mixture of grout is used to bond the soil nail into the borehole. Pumped into each borehole, the cementitious grout sets each nail, pinning back a small section of the face. Multiple soil nails are installed in a regular pattern to fully stabilize the slope, creating a composite mass similar to a gravity wall. High-tensile steel netting installed over the soil nails, along with a bearing plate attached to each nail to hold the mesh in position, prevents material between soil nails from slipping out. Advantages of soil nailing include versatility and a smaller environmental footprint. It is easy to shore along irregular curves and surfaces. Installation methods can be modified according to constrained access. When space for shoring is limited, especially for tall retaining structures, soil nailing produces a much smaller footprint than laying back a slope. Typically, soil nails are installed with standard rotary highimpact drill rigs or Caterpillar® vibrators. More recently, a new hero of stabilization, GeoStabilization International®’s (GSI®) Soil Nail Launcher™, armed with their SuperNail®, employs its power to launch tendons of steel into the earth. Originally developed by the British military, the Soil Nail Launcher is a compressed air cannon which can accelerate a 1.5-inch-diameter, 20-foot-long steel or fiberglass tube to 250 miles per hour in a single shot. As these high-speed projectiles enter the earth, they generate a shock wave, causing the soil particles to deform (jump away) from the nail tip. The bars enter without significant abrasion or loss of exterior corrosion protection. Soil particles then collapse onto the bar in a relatively undisturbed state, yielding pullout capacities up to ten times greater than driven or vibrated rods or tubes, and increasing soil density in the nailed area. Launched soil nails can also be perforated to allow for horizontal drainage and pore water pressure relief. Usually mounted on a modified tracked excavator, the launcher can also be mounted on vehicles, long reach excavators, or crane basket frames. Weighing about two tons, it is portable and able to reach remote locations. With full articulation, it can work around overhead wires, underground utilities, and guard rail. The launcher’s mitigation partner, the advanced SuperNail can be installed faster than any other soil nail technology at over 250 20-foot nails per day. These can be used in collapsing holes, areas with voids, actively moving landslides, and at depths of up to 120 feet in soil, rock, or a combination of the two. Depending on the design services specified, anywhere from one to four layers of corrosion protection will guard the tensile element for permanent application. In very aggressive soil conditions or coastal environments, GSI can also use fiberglass instead of steel to construct the nails. Landslides are natural geological hazards, proving to be catastrophic for people and property in many cases. To counter these destructive scenarios, it is important to create stabilizing slopes which last longer and become part of the infrastructure. As engineers of soil nailing technology continue to innovate, these new advances hold great promise for landslide mitigation. Photo of Soil Nail Launcher courtesy of GeoStabilization International.

17 AUGUST 2021 WorldWide Drilling Resource® In Memoriam Gregory E. “Greg” Haupt (1953~2021) Gregory E. “Greg” Haupt of Auburndale, Wisconsin, passed away on Memorial Day, May 31, 2021. Born in 1953, he graduated from high school in 1971, then went on to get his associate’s degree in instrumentation form Mid-State Technical College in Wisconsin Rapids. He was co-owner, drill operator, and pump installer at Haupt Well & Pump Co., working there nearly his entire life. He was well-versed in the trade and thoroughly enjoyed the work he did. He was also an avid deer hunter, model train enthusiast, and loved working on projects around the house. Greg is survived by his wife Joyce; daughter Katie (Maria); son Jacob; grandson-on-the-way Leo; dog Frankie; and several brothers and sisters. Winslow “Win” Parker (1946~2021) The Florida Ground Water Association was saddened to announce the passing of former member Winslow “Win” Parker on June 7, 2021, in Lake Worth. He was born in Boca Raton in 1946. For a time, he was first mate on the fishing vessel Boca Jima. Win founded Parker Well Drilling in 1979, working there until he retired in 2018. Win leaves behind his wife Sandra; sons James and Marc (Kathy); daughter Julie (Steve); grandchildren Justin, Chelsey (Jeffrey), Kristen, Parker, and Aubrey; great-grandson Carson; sisters Maxine, Gail, and Charlotte; and brother Chuck. John W. Errington (1956~2021) The New Jersey Ground Water Association sent sad news that former Board Member John W. Errington passed away on June 7, 2021. John’s successful career at Duff Co. in Norristown, Pennsylvania, spanned 48 years. When occasionally talking about retiring, John would say he wasn’t suited for it, that he liked working. Maybe that’s because it didn’t feel like work to him. He even met his wife Sue at Duff Co. He was hired at the age of 16 to work in the warehouse, and over the years, he blossomed into a top salesperson, forging relationships along the way by treating everyone with respect and being fair. He was actively involved with his sons’ Cub Scouts, Little League, and Methacton Football. He enjoyed ballroom dancing with Sue, relaxing at the Jersey Shore, cruising, playing golf, and watching the Phillies. John will be greatly missed by Sue; sons John and Jason; brothers and sisters; many nieces and nephews; and the entire Team at Duff Co. Larry Dean Madrid (1960~2021) With heavy hearts, Madrid CPWG, Inc. announced the passing of President Larry Dean Madrid on June 18, 2021, in Lakeland, Florida. He was born in Colorado Springs, Colorado, and graduated from Colorado State University with a bachelor’s of civil engineering and a master’s in geotechnical engineering. He was greatly respected in both the engineering field and local business community. Larry was just as much an artist of music and photography, as an engineer. He served as the worship leader and choir director at Fellowship Baptist Church for over 30 years. He played guitar, wrote numerous songs, and loved to sing, both for the Lord and at community events. His rendition of The Star Spangled Banner was awesome. Larry is survived by his wife of almost 40 years, Connie; sons Andrew (Chelsea), Phillip (Danae), and Daniel (Kathryn); three grandchildren; brothers Thomas (Christine) and J.D.; sister Patricia (Edward); and many nieces and nephews. Madrid CPWG vowed to honor and continue the legacy Larry built. Lest we forget...

18 AUGUST 2021 WorldWide Drilling Resource® 000 & 50 sec pS a 5 ™ 8 tseFlli l rD e om Hn ow D de i e Wdl or W launnA nd ocec S eh t su eeS a t Through the Back Door! by Jim Kuebelbeck As a water dowser, I have amassed more memorable accounts over the years than I am able to relate within the pages of WWDR. Most memorable are accounts of the locating of satisfactory groundwater sources in areas where, after the drilling of numerous dry or unproductive water wells, drilling professionals, geologists, and hydrogeologists had determined that satisfactory groundwater sources were not likely to be encountered on the property. In these last resort situations, as a water dowser, it is quite satisfying to be able to locate good groundwater sources in the very areas where such supplies were thought not to exist. Although I am able to locate the most promising sites to drill a satisfactory water well on a piece of property, I am always reluctant to accept requests to locate irrigation wells for farmers and ranchers. I can locate the most promising drilling sites in these situations, but I have no control over the existing geologic structure beneath the surface. There can be a billion gallons of water below, but if the existing geology will not allow the free passage of water through it, the hundreds of gallons per minute needed for an irrigation well cannot be obtained. I always make this as plain as possible to the landowner, hoping they will not hire me. This often falls upon deaf ears, however, and I am hired anyway. Carol often tells me not to accept any more irrigation jobs, because “one of these times we'll probably get to a piece of property where the desired volume of water cannot be obtained, and the landowner will hate us forever!” So far this hasn't happened, but I know the day might be coming. Two Minnesota well drilling contractors called us recently and asked if we were willing to locate a site for irrigation wells on properties where they were unable to do so. I told them of Carol's advice to me about not accepting any more jobs for irrigation wells, but they wouldn't listen. We had worked for them in similar situations in the past, and Carol finally agreed to do “only two more” irrigation jobs! Both jobs turned out well, however (no pun intended). One of the sites we selected produced about 1000 gallons a minute, and the other site produced almost 2000 gallons a minute; but from now on, I think I'll let Carol handle all future irrigation requests! The statements and comments in this article are based on information and references believed to be true and factual. If you have any questions or comments, please forward them to me in care of WWDR.
