8 DECEMBER 2025 WorldWide Drilling Resource® The Un-Comfort Zone II by Robert Evans Wilson, Jr. Propaganda has Logical Fallacies if You Look Close Enough Over the past couple of years I’ve seen this bit of propaganda show up periodically on social media: “When my child hits another child with a stick, I don’t blame the stick, but I still take the stick away.” Now, we all know this isn’t about sticks, but taking it literally, I’d like to share the following stories: In the spring of 2008, a nine-year-old boy hit my nine-year-old son with a baseball bat just before a Little League game. They were on opposing teams and were warming up before a game. In the spirit of rivalry, both teams were yelling back and forth in a typical grammar-school sing-song fashion, “We're gonna win and you're gonna lose.” Suddenly, a boy who was taking batting practice went into a rage and ran into the crowd of my son’s team swinging his baseball bat and hit my son on the shoulder. Immediately, a dozen or so adults intervened, the bat was taken away from the boy, and he was led away. No one else reacted and the episode did not escalate. My son was okay and went on to play in the game. Remarkably, nothing was done to discipline the kid who hit my son. I was pretty upset by that. The kid was out of control, and no one did anything to let him know what he did was wrong. He was their team's star player, and known to be the best batter on the team. By age nine, a boy should know better than to hit anyone with a baseball bat, and should know how to regulate his anger, and should know jeers of rivalry are not the same as bullying. At a minimum, he should have had to sit out that game as punishment; instead he was allowed to play! My son went on to pitch in that game. When the out-of-control boy came up to bat, my son threw his first pitch very close to the boy’s head. “Chin Music” as they call it in baseball because you can hear the sizzle coming off the seams when it passes close by your head. He did not throw to hit the boy, but to scare him into thinking he might be seeking revenge. It worked. The boy stepped way back in the batter’s box to avoid getting hit by my son’s fastball pitches. My son then threw three successive strikes right over the plate, getting the opposing team’s star batter out. It was the only consequence that boy had to suffer for hitting my son with a bat. I was proud of my son for delivering the lesson so well. Too bad the other boy’s coaches or parents couldn’t have done the same for him. Three years later, my son aged out of Little League, and we never saw that kid again. A few years ago, I read in a local newspaper how that boy, at age 23, died from a heroin overdose. While I grieved for his parents, I couldn’t help but wonder if the boy's life might’ve turned out differently had he been made to face the consequences of his actions earlier in life. No, the baseball bat wasn't to blame; it was the boy’s lack of a moral compass. When I was a child of about eight years old, I was playing quietly alone in my yard on one side of a stream. Five or six boys showed up on the other side of the stream. They were led by the neighborhood Scut Farkas (the redheaded bully from the movie A Christmas Story), who was at least two years older than me. He started throwing rocks at me, and the other boys quickly joined in. I was hit by several rocks, but stood my ground and started throwing rocks back at them. One of the rocks I threw hit the bully in the forehead and drew blood. He ran home crying. A few minutes later, his mother showed up and started yelling at me. My mother came out of the house, and told the bully’s mother that her son started it, and deserved exactly what he got. The bully’s mother was silenced and left. I was never prouder of my mother than in that moment. I never saw the bully again even though he lived just two doors down from us. No the rocks weren’t to blame, and the one I threw didn’t defend me by itself, I did that, but I was grateful I had some rocks to defend myself with that day. Now let’s deconstruct the original propaganda: “When my child hits another child with a stick, I don’t blame the stick, but I still take the stick away.” This is a False Cause fallacy because it implies that removing the stick removes the problem without addressing the behavior of the child, which is the true source of the problem. This is also a False Dichotomy or False Dilemma fallacy because the statement sets up an either/or scenario, which limits the listener to two options when many others likely exist. The false dichotomy is you either blame the stick or you remove it, but it is implied that removing the stick is the correct solution. This is misleading because it offers only two choices, and again ignores the person wielding the stick and his or her motivation. This statement is also guilty of the logical fallacy of Begging the Question, also known as Circular Reasoning. The statement implies that sticks are inherently bad and should be removed, but it does so without explaining why sticks should be treated differently than other objects. This form of argument assumes the conclusion (sticks must be removed to reduce hitting) as part of the argument itself. It’s circular reasoning because the statement assumes removing sticks solves the problem of hitting without providing any evidence or reasoning to prove why removing sticks would be an effective solution. Finally, this statement is also guilty of the logical fallacy of Oversimplification. It oversimplifies the issue by focusing on the stick rather than the underlying causes of the hitting. The statement suggests removing the stick solves the problem, but it ignores the real problem, which is: Why the child was hitting another. The hidden agenda here is that all sticks should be removed from society so they can never be used by anyone ever again to hit someone or, for that matter, be used for any legitimate purpose such as self-defense. Feel free to replace the word “stick” with the name of any type of weapon. Robert Robert is an innovation/change speaker, author, and consultant.

11 DECEMBER 2025 WorldWide Drilling Resource® A Tunnel Boring Machine Named Emily Adapted from Information by High Speed (HS2) A tunnel boring machine (TBM) is much more than an underground drill; it’s essentially a subterranean factory. These massive machines carve their way through the earth, erecting walls lined with large concrete segments and securing them into place with grout, all while advancing to form the next section of the tunnel. Operating around the clock, they are engineering wonders, yet they remain unseen by the public eye. The TBM Emily is one of four utilized for the construction of the Northolt Tunnel in London - an eight-mile passage designed to transport HS2 trains from Old Oak Common Station to the fringes of the city. Following a longstanding tradition, the machine was named after Emily Sophia Taylor, who played a pivotal role in founding the Perivale Maternity Hospital in 1937, before becoming Ealing’s first female mayor in 1938. During the subterranean journey, TBM Emily excavated an impressive 868,000 tons of clay and installed 17,514 concrete segments. However, the success of the TBM is not solely dependent on the machine itself; a complex logistics operation is essential for its continuous advancement. To maintain a steady flow, concrete segments are stockpiled at the tunnel entrance. A fleet of specialized vehicles, designed with cabs at both ends to navigate the tight confines of the tunnel, transport these heavy segments to the TBM. As the tunnel stretches longer, the efficiency of this logistical chain becomes increasingly vital. Onboard the TBM, a dedicated crew of approximately 17 individuals oversee various aspects of the tunnelling operation. Their responsibilities include steering and maintaining the machine, installing the concrete rings, and ensuring a watertight seal through grouting. They are aided by a ground control team stationed aboveground, who continuously monitor progress and collaborate with the tunnelling team to adjust speed, as well as pressure, based on varying ground conditions. Recently, engineers at the Green Park Way site celebrated a milestone as they lifted the first section of TBM Emily from the ground, marking the successful completion of her three-mile journey. Following this achievement, the decommissioned TBMs are being extracted from the tunnels, disassembled, and sent back to their manufacturers, where some components will be repurposed for new machines.

As part of this project, a sheet pile retaining wall was installed providing permanent support for the section of the stadium built below ground level. To reinforce the wall, anchors and walers were incorporated by drilling holes through the sheet pile and into the underlying soil. However, during installation, the anchor points were not completely sealed, resulting in gaps allowing soil to escape through the wall. If not addressed, this issue posed a risk of developing voids and compromising the structural stability of the wall. To ensure the retaining wall’s integrity throughout the construction phase and prevent soil migration, Lincoln Company LLC was contracted to seal the anchor penetrations. This repair required a quicksetting material capable of creating a robust seal behind the sheet pile, resistant to the pressure of the surrounding soil. Crews excavated some of the nearby soil to provide adequate space for the sealing material to establish a backstop. Terrathane™ 24-010, a high-performance dual-component polyurethane system from NCFI Geotechnical Polyurethanes, was selected due to its rapid expansion and effective sealing properties. Once injected, the foam functioned like a cork, securely anchoring itself behind each opening to prevent further soil loss and potential water infiltration. The polyurethane injection effectively sealed all anchor points, stopping soil intrusion and safeguarding the area behind the wall from the risk of void formation. By promptly and efficiently addressing the issue with Terrathane™ 24-010, the project team ensured the structural integrity of the retaining wall remained intact, allowing the stadium construction to proceed without interruptions. This solution provided lasting durability without necessitating any disruptive excavation or reconstruction efforts. GEOTECH

16 DECEMBER 2025 WorldWide Drilling Resource® An Upgraded Wastewater Treatment Plant for SURF Adapted from Information by the Sanford Underground Research Facility (SURF) SURF recently completed a significant renovation of its wastewater treatment facility in South Dakota, paving the way for many more years of pristine water flowing into local streams. For almost four decades, a collection of large cylinders, each comparable in size to a semitruck trailer, has been slightly turning in pools of moving water at SURF. Known as Rotating Biological Contractors (RBCs), these cylinders play an essential role in the wastewater treatment process at SURF. Inside the RBCs resides a specialized group of microbes that effectively decompose pollutants in the water passing through the plant. This system has served both the former Homestake Mine and SURF, successfully treating tens of billions of gallons of water since its inception in the 1980s. However, this year, the RBCs will be decommissioned to make way for more advanced water treatment technology. The innovative biotechnology used at SURF for water purification originated in the Black Hills nearly half a century ago. In the 1970s, chemists from the Homestake Mining Company identified a specific set of microbes capable of breaking down the contaminants present in mine tailings and the underground water pool. Homestake was a pioneer in utilizing these microbes for water treatment, leading to a global revolution in wastewater management that saw technology being adapted and improved over time. SURF is set to replace the outdated RBCs with a Moving Bed Biofilm Reactor (MBBR). Instead of relying on large rotating cylinders to support microbial life, the new system utilizes tens of thousands of small plastic disks that swirl through aerated pools, creating an effect akin to massive bubbling hot tubs. The construction process faced various challenges, including the careful decommissioning of the existing system and the excavation necessary for the new setup. “This has been a challenging project, and it’s turned out very successful. We had a huge job in removing the old RBCs and then safely excavating down to put this new MBBR basin in place. There were absolutely zero injuries during the construction of this MBBR plant,” said Todd Hubbard, a Senior Mechanical Engineer at SURF who led the construction of the MBBR. With the upgraded system soon to be operational, SURF is well-equipped to uphold rigorous water quality standards well into the future. “This plant allows us to meet all of our discharge permits and discharge it down to Whitewood Creek, which is a cold-water fishery. So, water treatment is very critical and crucial to protect this waterway,” said Hubbard. “Anybody that goes down to the creek and decides to drop a line and do a little flyfishing, those trout will be there for them in the decades to come.” Photo courtesy of Stephen Kenny WTR See us at Booth 2915 Groundwater Week 2025 in New Orleans [Overheard] Husband: I’m going clubbing tomorrow.

17 DECEMBER 2025 WorldWide Drilling Resource® In Memoriam Darrell Eugene Clark (1961~2025) Darrell Eugene Clark left this life on October 26, 2025, after a short illness. He spent his entire life in Grand Ridge, Florida, where he built a loving family and grew a thriving business. During his school years, Darrell was active in many organizations, but truly excelled in the Future Farmers of America (FFA) program, earning the Florida FFA State Agribusiness Award. He was often “checked out” of school to help his dad, Mack, run Clark’s Well Drilling - a business built on integrity, perseverance, and service to others. He often told stories of those early days on the rig, when equipment was old and comfort was scarce. One bitter January morning he recalled driving a rig without a windshield - his hands so cold he had to keep switching them on the wheel, warming one while driving with the other, his eyes watering from the icy wind. Even then, he pressed on. Those long days beside his father laid the foundation for a work ethic and determination that would define his life. Darrell built on what his father had started. Many people who knew him said Darrell was always resourceful and one of the best fabricators around. He accomplished many things in his lifetime and did them all in what his family lovingly called “The Darrell Way.” One of his proudest achievements came in recent years when he and his sons successfully drilled a 30-inch well in Orange Beach, Alabama. Unbeknownst to at the time, it would later be recognized as the largest public well in the state. His life was defined by hard work, deep faith, and a love for family and the simple joys of life. Whether drilling wells, tuning up a Ford, or sitting quietly in a Kansas deer stand, he lived with purpose and gratitude. Those who knew him will remember his easy laugh, steady presence, and unwavering devotion to the people he loved most, and all who knew him have their own stories to share. His legacy lives on in the hands of his children, the hearts of his grandchildren, and the countless lives he touched. Darrell is survived by his loving wife, Pam; his children Brint (Meghan), Trint (Kennessee), and Nikita (Chris). His greatest joy came from being “Big Daddy” to his grandchildren Mackinna, Ella, Jeremiah, Myla, and Nehemiah, who brought endless happiness to his days. Bud Benjamin Bachelder (1941~2025) Bud Benjamin Bachelder passed away on October 3, 2025, at the age of 84. Born in Rabbit Lake, Saskatchewan, Canada, in 1941, he grew up on the family farm. His early working days were spent on a horse-powered drill rig, learning the grit and precision that would define his career. He married Dorothy and moved to Assiniboia, in 1966, where he later co-owned and operated Anderson Water Well Drilling. He worked long, hard days, but pride in his work was always evident. In 1979, they relocated Anderson Drilling to Prince Albert, where it operated until 1986. From 1987 to 2007, Bud and Dorothy turned their compassion toward a new calling when they opened their personal care home, then pouring their life into over 80 seniors. Together, they built a life rooted in hard work and service to others. Bud was also a talented welder, skilled at using a lathe, a capable mechanic, and a master of all things yard and home maintenance. His property was a reflection of his care and pride, with every tree trimmed, every patch of grass tended, and every tool had its place in his garage. In Bud’s mind, everything was fixable or could be rebuilt, from motors to go-carts. He never hesitated when someone was in need. Whether it was fixing a neighbor’s engine, mending a broken fence, or lending a listening ear, Bud was eager to offer a hand - not for recognition, but because that’s who he was. To his family, Bud was a source of wisdom and calm. He led by example, teaching that integrity is shown, not spoken; humor lightens even the heaviest load; consistency builds a good life. Preceded in death by Dorothy, Bud is survived by his daughters Cindie (Cory) and Susan; his brother Glen (Sheila); grandchildren Benjamin (Laurel), Joshua (Becca), Emilie, Samuel (Payton), and Jessica; as well as great-grandchildren Hunter, Alexei, Edward, Adeline, and Colter. The management and staff of WWDR extend their condolences to Darrell’s and Bud’s family and friends. Lest we forget . . . Let the WWDR Team honor your loved one with their own special place in WorldWide Drilling Resource® magazine, rather than just a one-liner. It is truly an honor for us.

18 DECEMBER 2025 WorldWide Drilling Resource® Groundwater Analysis Continues at Nuclear Testing Site Adapted from Information by the U.S. Department of Energy Efforts to document groundwater contamination caused by historic nuclear testing conducted in Nevada continue as the Environmental Management (EM) Nevada Program started drilling wells in a remote stretch of the Nevada National Security Site (NNSS). Drilling on the Pahute Mega region began earlier this spring, reaching a final depth of 2570 feet belowground before moving on to a second well and deepening an existing third well. Groundwater will be collected from all three wells for contamination analysis and compared with computer modelings. “The drilling supports future closure of the final groundwater corrective action unit at the NNSS,” said EM Nevada Program Manager Rob Boehlecke. “To do so, we need hard data. The goal is to demonstrate the reliability of our groundwater contaminant transport model results and provide confidence that the model results can support decisions leading to closure.” Between 1951 and 1992, the government carried out 928 nuclear tests at the NNSS, with roughly 90% of the tests being detonated underground. In 1989, the U.S. Department of Energy Office of Environmental Management was assigned to documenting the extent of groundwater contamination caused by the tests and determining where the contaminated water is headed, as well as the flow rate. Over the years, there have been several groundwater initiatives at the NNSS. In 2016, Frenchman Flat was the first groundwater corrective action unit EM closed. The Yucca Flat groundwater region was brought to closure in 2020. The same year, the Rainier Mesa and Shoshone Mountain groundwater corrective action unit reached closure three years ahead of schedule to the result of $5 million in federal savings. In 2023, after extensive scientific analysis, the EM Nevada Program reached what is known as the model evaluation stage for the final groundwater corrective action unit of Pahute Mesa. The current drilling campaign included extensive planning carried out by EM Nevada Environmental Program Services contractor Navarro Research and Engineering. Navarro Field Operations Manager Brian Haight said protecting workers has been the top priority for the team since day one. “There has been a lot of effort focused on both safety and using the newest technology,” Haight said. Navarro worked with subcontractor Premier Drilling to use a top drive drill rig system, which reduces the need for manual labor on the rig. “We are extremely happy with the progress made. We are confident that the wells will produce quality data to support closure at Pahute Mesa,” Haight concluded. Drilling at the first site.

Working with Many Challenges Adapted from Information by Keller Amidst a construction boom in downtown Denver, Colorado, a new seven-story mixed-use building was erected on one of the final available lots adjacent to the Platte River. The project necessitated a 30-foot-deep excavation to accommodate two levels of planned underground parking. The subsurface conditions revealed a mix of fill and alluvium underlaid by claystone bedrock, with groundwater located 15 feet beneath the surface. The claystone bedrock demonstrated expansion and contraction properties similar to expansive clay when subjected to wet and dry cycles. Since the parking levels were situated below the water table, the Denver Building Code mandated the consideration of buoyancy effects in the design, necessitating a strategy to mitigate buoyancy challenges. Compounding these issues, the site was riddled with a complex network of underground utilities, which required adjustments to the design to navigate these constraints. Following a consultation on the geotechnical aspects, Keller was engaged to provide solutions for excavation support and deep foundations. Prior to the commencement of construction and excavation, temporary dewatering wells were installed to ensure a dry environment for the excavation support system and foundation work. To support the 30-foot excavation, 27,000 square feet of soldier piles and lagging were installed around the perimeter of the site. This shoring system was reinforced with two rows of tieback anchors, some extending up to 50 feet in length. Micropiles were selected as the optimal foundation solution to handle vertical compression loads from the structure, as well as tensile buoyancy forces. Utilizing 3D modeling, Keller was able to identify and avoid potential conflicts with existing utilities during the installation process. A total of 479 micropiles were installed, reaching 50 feet below the working grade and extending beneath the expansive bedrock layer. CONST GEOTECH

The well reached a true vertical depth of 15,765 feet and is anticipated to achieve a bottom-hole temperature of 520ºF (271ºC) following complete thermal equilibration. Remarkably, Fervo completed the drilling of the Sugarloaf well in just 16 days, making a 79% reduction in drilling time compared to the U.S. Department of Energy’s benchmark for ultradeep geothermal wells. During the drilling of what is now Fervo’s hottest and deepest well to date, the company set multiple performance records, including a maximum bit run length of 3290 feet, an average rate of penetration (ROP) exceeding 300 feet/hour at depths beyond 15,000 feet. These achievements broaden the potential for commercial EGS viability into significantly deeper and hotter environments, paving the way for deploying this technology beyond the western United States. An independent assessment by DeGolyer & MacNaughton, which involved a thorough review of Fervo’s drilling data, geological models, and production test outcomes, estimated the heat-in-place and reserves. The report indicates Fervo’s innovative EGS design can unlock thermal recovery factors between 50% and 60%, effectively tripling the amount of usable thermal energy reserves. It also confirms the Cape Station project area is capable of supporting over five gigawatts of development at depths of up to 13,000 feet, with the new Sugarloaf drilling results likely to enhance Cape’s resource potential even further. “Back in July 2020, we performed our first EGS field trials at reservoir temperatures of around 300°F [149ºC],” said Jack Norbeck, CTO and Cofounder of Fervo Energy. “In just a few years, we’ve developed innovations that enable our technology to operate reliably at temperatures exceeding 500°F [260ºC]. These drilling results demonstrate that Fervo is operating in the optimal geothermal conditions for large-scale commercial deployment.” As the demand for power in the U.S. surges, Fervo’s ability to harness firm, carbon-free energy from deep underground heat reservoirs positions the company as a vital player in the nation’s energy landscape.

Coleman, President and CEO of EFC, announced the commencement of vital drinking water and sewer improvement projects in the Village of Menands, amounting to $12 million. This initiative aims to upgrade aging pipelines to ensure the safety of drinking water and public health, protect the Hudson River, and foster a more resilient community. Funding for these projects comes from a mix of state, federal, and local sources, with nearly $5 million provided in state grants to help keep costs manageable for local residents while creating good-paying jobs in the Capital District. The Wastewater Resiliency Project is to mitigate environmental impacts and adapt to increased rainfall; the Village is set to replace around 10,000 linear feet of aging clay sewer pipes in the South End neighborhood. The enhanced infrastructure will: j Prevent groundwater and stormwater from overwhelming the sewer system j Alleviate pressure on the Albany County North Wastewater Treatment Plant j Reduce occurrence of untreated or partially treated discharges into the Hudson River during storms In parallel, the Village is addressing urgent drinking water infrastructure issues in the same area, where 80- to 90-year-old water mains have become unreliable, leading to frequent breaks and service interruptions. The Village plans to replace approximately 12,500 liner feet of water main and upgrade the interconnection with the Watervliet water system to provide a dependable backup water supply. This modernization will enhance system reliability, lower emergency repair expenses, and ensure a steady supply of clean drinking water for residents. Albany County Executive Daniel P. McCoy said, “Protecting our residents by making sure they have clean, safe drinking water is vital, and Governor Hochul understands that. Her commitment also recognizes that cost should not be a factor when it comes to safety. I want to thank the Governor, and all the partners at the local, state, and national levels for investing in this modernization of outdated pipes for water and sewer systems in the Village of Menands.” Beyond improving water quality, these projects will also create jobs in construction, manufacturing, engineering, and related industries. Completion of the projects is anticipated in 2027. WTR
