HAS YOUR SHIP SAILED? H Is your company suffering because . . . It appears most of us are in a cocoon state these days; not sure whether to turn right or left ~ move forward or backward. So actually, since that is NOT the way HUMAN BEINGS live, we aren’t living at all. We are existing and doing nothing, waiting for someone else to do something - perhaps that will get us all moving again? “Well, I gotta tell ya” . . . as my dear friend John says (and yes, John, you know who you are) . . . That ain’t getting you anywhere and YOUR LIFE is whiling away while the few of us who are actually doing and moving are trying to get you to understand - NO ONE ELSE WILL DO ANYTHING FOR YOU. YOU GOTTA DO IT FOR YOURSELF . . . No, the Government will not! Remember in the proverb, “If you teach a man to fish, you feed him for a lifetime”. And even before all this mess started, we weren’t dependent on anyone but ourselves. To me that felt good. We were helping others learn how to plant crops, raise cattle, hogs, chickens, etc. - Why? So they could live as HUMAN BEINGS and not as second, or even third class citizens. TO BE CONTINUED . . . April issue. TIME OUT FOR A COST-SAVING TIP courtesy of TBTC (Teddy Bear Timber Corporation) To get the best bang for your buck, if you are doing a home improvement project and only need a half-sheet of sheet rock; when you go into your box store, look for a damaged sheet that will work in the area you need it in. Then take it to the front counter and ask if you can get a discount for the damaged section. This way you are helping out the store by removing a damaged product and you are getting what you need by being able to use most of the sheet. The rest is waste. But remember, you were going to have to throw the rest of a good sheet away and would have had to pay for what you were throwing away.

7 MARCH 2022 WorldWide Drilling Resource® Teams Create Tools to Address Geothermal Challenges Adapted from Information by the U.S. Office of Energy Efficiency & Renewable Energy The U.S. Department of Energy announced finalists of the American-Made Geothermal Manufacturing Prize, a competition designed to advance geothermal energy technology using 3D printing. Harsh conditions such as high temperatures, high rock strength, and corrosive working fluids in geothermal environments require specialized tools and materials. Manufacturing innovations can address some of these fundamental challenges while helping lower costs, enhancing production, and increasing the reliability of geothermal energy to bring affordable power to more Americans. “This prize will incentivize entrepreneurs and innovators to develop more cost-effective methods and materials to overcome the challenges of working in a geothermal environment,” said Principal Deputy Assistant Secretary for Energy Efficiency and Renewable Energy Kelly Speakes-Backman, who announced the finalists at a live event. “Our focus on rapid prototype development will accelerate geothermal innovation, resulting in more geothermal power generation across the nation . . .” The prize engages America’s energy incubators, investors, universities, national laboratories, and others to harness rapid advances in 3D printing for tool design, fabrication, and functionality. Advancements in 3D printing, also known as additive manufacturing, can be leveraged to support the manufacturing needs of the geothermal industry, helping to improve performance and reduce costs and production time. Teams have been participating in a series of progressive competitions for a total prize of $4.65 million in cash and other incentives. As part of Make!, the third of four contests, semifinalists fabricated prototypes and presented them to a panel of expert reviewers. This contest followed the Ready! and Set! contests, where teams developed impactful ideas and began demonstrating their design’s promise. Five teams were selected to move on to the Geo! contest, the prize’s final stage. The finalists are: a Team Baker Hughes (Houston, TX): Baker Hughes is developing high-expansion packers with additive manufactured backup rings. With an inventive, interlocking petal design, these backup rings will improve the zonal isolation in both open and cased geothermal wells. a Team Downhole Emerging Technologies (Houston, TX): Downhole Emerging Technologies is developing an innovative alternative to traditional packer systems. The retrievable, all-metal packer system is designed specifically for high temperatures, extreme pressures, and corrosion experienced in geothermal wells. a Team PLUGS (Morgantown, WV): PLUGS is developing a sparger system using high-pressure air for artificial lift, which replaces traditional electric pumps. The technology addresses maintenance issues experienced by existing pump technologies due to harsh geothermal conditions. a The Bit Guys (Morgantown, WV): The Bit Guys is developing an air hammer drill bit with carbide cutter retention technology that tackles drilling-related challenges in geothermal environments. Basement rock is notoriously difficult to drill through and this bit technology addresses both the strength and temperature requirements for geothermal drilling. a Team Ultra-High Temperature Logging Tool (Houston, TX): Ultra-High Temperature Logging Tool is developing a technology using a labyrinthian heat sink to reduce thermal emissivity and increase exposure time of temperaturesensitive electronic components. The technology solves limitations around maximum temperature rating and lifetime of electronics in logging and measurement tools. As part of the Geo! contest, these finalists will manufacture an advanced functional prototype and field test it using partner facilities. Teams will receive feedback from experts to help them refine their prototypes. Ultimately, the work conducted by these contestants will result in innovative uses of 3D printing to discover new advanced manufacturing solutions for the geothermal industry. TheAmerican-Made Geothermal Manufacturing Prize launched in January 2020 and is supported by the Geothermal Technologies Office and the Advanced Manufacturing Office in partnership with the National Renewable Energy Laboratory and Oak Ridge National Laboratory. WWDR featured winners of the Ready! contest in the February 2021 issue. High-pressure, high-temperature ultra expansion packer by Baker Hughes.

9 MARCH 2022 WorldWide Drilling Resource® New Alliance for Geothermal Energy The Texas Geothermal Energy Alliance (TxGEA) advocacy group, created to advance geothermal energy in Texas, officially launched operations. This broad interdisciplinary group of entities is engaged in geothermal resource exploration, well drilling, plant construction, resource production, and markets creation. TxGEA includes representatives from the oilfield service sector, gas & oil operators, utilities, start-up companies working to advance geothermal relevant technologies, scientists and engineers from several Texas universities, and leading environmental organizations advocating Texas public policy solutions. The Texas energy sector has benefitted tremendously from a diversified energy portfolio which has included oil, natural gas, wind, solar, coal, and nuclear power. In addition to these, Texas has the opportunity to utilize undeveloped geothermal resources in the near-term to produce reliable and secure baseload electricity. Geothermal plants can operate 24 hours a day with a steady output, regardless of environmental conditions, and are not subject to the unpredictability and voltage swings other energy resources face. Geothermal plants can also ramp up or down quickly, adjusting to the changing needs of the power system and act as a flexible power source in addition to baseload. Barry Smitherman, past chairman of the Public Utility Commission of Texas and past chairman of the Texas Railroad Commission, who is guiding the formation of TxGEA said, “The rise of geothermal energy is coming at a pivotal time in Texas. The technological advances, coupled with energy market incentives and a supportive legislative and regulatory framework, will unleash tremendous geothermal energy potential, as well as position Texas as the global epicenter of next-generation geothermal innovation.” For a link to this website, visit this page at: worldwidedrillingresource.com www.starironworks.com 257 Caroline Street Punxsutawney, PA 15767 800-927-0560 • 814-427-2555 Fax: 814-427-5164 SERVINGTHECONSTRUCTION INDUSTRY Serving the Drilling Industry

12 MARCH 2022 WorldWide Drilling Resource® Hammers / Bits / Tooling by Ronald B. Peterson Drilling Products Specialist, Mountainland Supply Company This month, we will briefly discuss the downhole assembly, including hammers, bits, collars, and tooling; along with their interaction with drilling fluids. Fluids are by definition, anything that flows and takes the shape of its container. Fluids can be either gas or liquid. When drilling with a hammer, fluids are often simply air - although it is somewhat compressed. In hammer drilling, the fluid or air has multiple purposes. You need to have sufficient air to trip the hammer and make it strike the bottom of the hole firmly enough to cause it to fail or break and create cuttings. It then passes around the bit, cleaning the cuttings created by the hammer action - this is from the bottom of the hole to ensure the hole is clean so more cuttings can be created by future hammer blows. The air then has to move up the inside of the drill pipe fast enough so it can carry the cuttings with it to the surface. When drilling with a conventional bit, the air goes down the drill pipe, around the face of the bit, and up the annulus of the borehole. The air in this case actually has to have a higher volume to carry the cuttings up the hole, since there is typically more space in the annulus. This results in a need for larger volumes of air to clean the hole. When circulating the air up from the open hole at the volumes and speeds required, it can be very erosive to the borehole and cause borehole instability, so it works best if the borehole is very competent. There are two ways to clean the borehole - velocity and viscosity. One of the ways to reduce the amount of air required, is to make it thicker by adding a foaming agent and/or a polymer so it can better carry the cuttings out of the hole. This also reduces the potential erosion of the borehole. When drilling conventionally with a fluid, the basic ingredient used in water well drilling is water. Like air, there are still two ways to clean the borehole - velocity and viscosity. The water, just like the air, can be made thicker by adding the proper additives to it. This reduces the velocity of the fluid and helps maintain borehole stability. In reverse circulation, the drilling fluid goes down the annulus, around the face of the bit, and up the inside of the drill pipe. In conventional circulation, the fluid goes down the drill pipe and up the annulus. In either case, the fluid must cool and lubricate the bit, clean the bottom of the hole, and carry the cuttings back to the surface. In any case, the drill pipe will have lower velocity and the collars (bottom hole assembly) will have a higher velocity. This is simply a thumbnail sketch of the interaction of the hammers, bits, drill string, and bottom hole assembly. We will discuss more specifics in other articles. Feel free to contact me or your drilling fluids professional for more detail. Ron Ron Peterson may be contacted via e-mail to michele@worldwidedrillingresource.com WTR

Sometimes the Best Thing to do is Just Blow it Up by Britt Storkson Owner, P2FlowLLC Britt may be contacted via e-mail to michele@worldwidedrillingresource.com The Epoch Times newspaper recently published an article about a fellow who bought a brand new Tesla car and reported during the first 1500 miles the car worked fine. Then he started getting computer error codes and, after several trips to the Tesla dealer, the dealer recommended he replace the battery bank. As for how much was it going to cost, this Tesla owner was told: “At least $22,000.” Talk about sticker shock! On top of that, Tesla refused to pay the bill. So what’s a fellow to do when he buys the Mother of all Lemons? Take it out to a rock quarry, strap about 80 pounds of dynamite to it, and blow it to smithereens. Watch it here: https://www.youtube.com/watch?v=DG9Izqp6WWU We don’t know what component(s) failed on this car, but one of the common causes of electric car failure is internal disconnection of the battery cells. These cells are connected in series . . . meaning the “+” terminal on one battery is connected to the “-” terminal on the next battery, which doubles the voltage output while maintaining the same current (amperage) output. For example, the typical lead-acid car battery has six cells connected in series to deliver 12 volts. Any number of batteries can be connected in series to create a wide variety of voltage outputs, up to several hundred volts. The connections between batteries can be “tapped” to provide voltages below the final output simply by connecting a wire between the “+” and “-” terminals of the two batteries. To illustrate this, if you have a 12-volt lead-acid battery, it has six cells wired in series with each cell producing about 2 volts, so the sum total (6 cells x 2 volts) would be about 12 volts. Using a DC (direct current) voltmeter, if you test the voltage from the battery “+” terminal to the “-” terminal on the first cell, you will measure about 2 volts. Testing the voltage from the battery “+” terminal to the “-” terminal on the second cell will measure about 4 volts, and so on. One of the problems with this type of battery construction is it only takes one internal connection from battery to battery to disconnect or “open up” due to vibration, temperature cycles, a minor collision, or other factors - and the entire battery bank is toast. There can be small electrical loads from these “tapped” connections, but most of the time they are used for testing purposes. Each one of these “taps” can be input to a computer and the battery cell condition can be determined. It’s one thing to know there is a bad cell. It’s quite another to locate, remove, and replace the cell. The cost is often prohibitive and one does not know the condition of the other cells. There’s no sense spending time and money to replace one bad cell, only to have another cell fail a few months later. Electric vehicles are fine for certain applications, such as golf carts and light delivery trucks where they can be recharged every night, but the technology just isn’t there yet for “road ready” electric vehicles. Among other things, one can only store so much energy in a finite space and charging times are still measured in hours, not minutes like filling up the car with gasoline. Electric car costs are about ten times what a similar gasoline engine can deliver in terms of power and fuel economy - and that’s not counting repairs needed from time to time. There’s no sense in buying any vehicle that cannot be repaired in a timely and cost-effective manner. 14 MARCH 2022 WorldWide Drilling Resource®

15 MARCH 2022 WorldWide Drilling Resource® Tricone Bit Bearings Explained Adapted from Information by Bit Brokers International The bearings are what make the cones on a tricone spin. There are four common types of bearings - standard open roller, air-cooled roller, sealed roller, and sealed journal (friction) bearings. What is the difference between sealed bearing bits and nonsealed bearing bits in tricones? Well let’s take a look at each of the different types of bearings, and discuss some of the differences. Standard Open Roller Bearing - Standard Open Roller Bearings are bearings without a seal. This means the bearings are open to outside debris, which can enter through the cone. The advantage of an open bearing bit is that they are usually less expensive. They are ideal for drilling shallow holes, in the hundreds of feet. If drilling deeper holes with an open bearing bit, you will probably have to pull it out every couple hundred feet to clean out the debris in the cones to free them up. Air Cool / Air Blast Bearing - Air Blast Bearings are equipped on Air Circulation Bits. These bits have air passages that supply air to the bearings for cooling and lubricating the bearing, and for cleaning the bearing of drilling debris. Sealed Roller Bearing - Sealed Roller Bearings have some of the features of the nonsealed open bearings, but longer lifetime because the bearings are sealed with an O-Ring Seal. A lubrication and compensator system prevents leakage into the bearing system and stops the possibility of debris blocking the bearing, as well as leakage of grease. Sealed Journal Bearing - Sealed Journal Bearings have very good durability and wear resistance. Instead of rollers inside the cone there is a floating bushing. The bushing is usually made of special material that is highly resistant to heat and galling (surface damage). DIR

16 MARCH 2022 WorldWide Drilling Resource® In Memoriam Dr. Calvin Joseph Konya (1943~2021) Founding member of the International Society of Explosives Engineers (ISEE), Dr. Calvin Joseph Konya of Hartsgrove Township, Ohio, passed away November 28, 2021. Born in Cleveland in 1943, he was a four-year varsity basketball athlete for the West Geauga High School in Chesterland. After graduating, he attended the Missouri School of Mines, completing numerous degrees. His coursework included major research in the development of blasthole spacing methods based on stiffness ratio, which is used throughout the world today. During college, he worked as a waiter, farmed large plots of grapes to sell to local wineries, and tended a large assortment of bees to sell honey to local markets. Dr. Konya went on to teach at West Virginia University, then later formed the ISEE, reaching out to major leaders in the explosives industry. He served as the first ISEE president and executive director, volunteering for 13 years until the organization had enough funds to hire an executive director to grow its membership. During this time, he started his consulting practice, Precision Blasting Services, leaving the university when his company took off quickly. He couldn’t pass up the opportunity to develop and lead the Ohio State University’s mining engineering program when they approached him. Also serving as a national exchange scientist with his sponsor country being Hungary, Dr. Konya toured every mine in that country, helping them optimize blasting while conducting groundbreaking research in blast design. The results were published in numerous books and papers. Dr. Konya was an avid writer and loved to share the stories and concepts of blasting, contributing to over 150 publications such as journals, conferences, and trade magazines. He also wrote over a dozen books which have been translated into languages around the world. Dr. Calvin Konya is survived by his wife of 51 years, Eva; children Anthony, Judy, Eva, and Ashley; and grandson Triston. His many friends will miss his gentle, stoic, kind ways. Charles Jackson Miller The Florida Ground Water Association was saddened to announce the passing of longtime member Charles Jackson Miller on December 19, 2021. Born in Columbia County, Florida, he graduated in 1955 with the last class of the old Gainesville High School, where he ran track and was involved in student government. Charles then enlisted with the Navy, serving his country in Guantanamo Bay, Cuba, and Rota, Spain. In 1962, he married Catrina who was from Kingston-upon-Thames, England. After the Navy, Charles assisted his father in the family business, Miller Well and Pump, eventually taking the reins as owner-operator. He was proud of his 50-year perfect attendance at North Central Florida Water Well Drillers Association monthly meetings, later receiving a lifetime achievement award. Charles is survived by his daughter Fiona; sisters Roz, Marilyn, and Virginia (Michael); and extended family. Catrina preceded Charles in death in 2017. Lest we forget . . .

17 MARCH 2022 WorldWide Drilling Resource® Pitcher Sampler - A Unique Tool for Soil Sampling Adapted from Information by Acker Drill Company Obtaining accurate soil samples in formations too hard for shelby samplers or too brittle, soft, or water sensitive for conventional core barrel samplers can be challenging. The Pitcher Sampler was specifically designed to overcome those challenges. Several years of successful application in virtually every type of “problem” formation prove this sampler not only saves time and money, but also provides exceptional accuracy. The Pitcher Sampler features: j A heavy-duty, triple ball-bearing hanger sealed four ways against drilling fluid to prevent freeze-ups and ensuring long, trouble-free service. j A spring-seated tube which means no more crumpled shelby tubes. Plus, no presetting or surface control is needed. j A sliding valve to direct drilling fluid. j No reaming is necessary, so your borehole remains the same size. j Drilling fluid can’t undercut the shelby tube and erode or contaminate samples even in softest materials. j No core lifter is needed to protect or retain sample. j Sample all materials of a hole - including soft rock - from top to bottom. j Tubes can be changed quickly. j Drill can be stopped, rod rechucked (even raised slightly) without breaking the core. Here’s how it works. As the sampler enters the hole, a sliding valve directs drilling fluid through the shelby tube to the bottom of the hole for thorough preflushing action. As soon as the shelby tube touches bottom, it telescopes into the cutter barrel closing the sliding valve which automatically diverts fluid to the annular space between the shelby tube and cutter barrel. For the remainder of soft formation sampling, drilling fluid can’t touch the sample, yet high fluid velocity is maintained at the cutting bit to clean the hole, delivering rapid cutter penetration. In softer materials, the shelby tube leads the cutting bit by as much as six inches to eliminate the chance of contact between the drilling fluid and sample. The amount of lead is determined by the material hardness. As the formation increases in hardness, the shelby tube telescopes into the outer barrel and compresses a spring which, in turn, exerts greater force on the tube providing adequate lead. In harder formations, the cutter may lead the shelby tube by as much as ½ inch to core out the sample. A sample loaded shelby tube can be removed, an empty tube attached, and sampler started downhole again within 45 seconds. There’s no fumbling, no danger of losing the tube screw. Hex-headed screw turns “in” to release tube; turns “out” to lock tube securely in place. ENV

18 MARCH 2022 WorldWide Drilling Resource® An Overview of Blasting Equipment, Methods, and Tools Adapted from Information by Global Road Technology A wide variety of tools and equipment are required for drilling and blasting. Traditionally, explosives were initiated by a fuse and ignitor cord which had a known range of burning speed, allowing miners to time the sequence of detonation of individual charges. This took place with very low accuracy. The latest technology in blast initiation uses a radio-controlled remote blast initiation system with a digitally encoded signal. These tools have the capability to initiate nonelectric shock tubes, as well as standard electric blasting caps. There are various types of detonators. Instantaneous and delayed electric detonators have been used for many years. They may be initiated by electric current from complex, main firing devices or from small portable devices called shot exploders. Modern methods of initiation blasting use shock tubes, which are nonelectric detonators capable of extremely accurate timing. Condenser blasting machines fire medium- and high-power detonators in a series. A NONEL® STARTER is an advanced electronic firing device for firing nonelectric detonators. Electronic firing systems offer detonator firing and electronic programming for complex, high-quality surface, underground, or demolition blasting operations. Tampers are used for placing charges in the drilled holes. Regulat ions and requirements for drilling and blasting are constantly changing as technology evolves. Measuring equipment employed before and after drilling and blasting is also catching the wave of change to the benefit of safety, health, and risk management. Before drilling takes place, there must be support tools for the firing and drilling plan design. Laser rock profiling systems are measuring devices which perform 3D rock face profiling to determine geometry and blasthole burdens, thus reducing incidents of flyrock, air blast, and excessive vibration. Laser profilers are also utilized to calculate theoretical distances for the face hole and drilling angles. After drilling, the measuring devices used offer a precise, quick means of checking the real deviation of the mining holes used before setting charges, which enables any firing incidents to be avoided. Laser profilers are used with software to create hole charge plans quickly and accurately on a hole-by-hole basis or for a whole row. Scattering risks are reduced considerably by using this measuring device. In addition, 3D laser technology provides information on total volume extracted, ore volume excavated, footwall waste dilution, hanging wall waste dilution, volume broken but not extracted (lockup), planned volume but not broken, ore development before stoping, and stope extraction design. The use of digital models contributes to the mining operation’s overall business model. The tools used in drilling and blasting operations contribute immensely to the success of operations. An integrated approach to technology and personnel is ideal. Choice of tools goes hand in hand with occupational health and safety. EXB

Driven by HydroVolve’s INFINITY engine, it uses percussive impulse energy to fracture rock ahead of the bit, enabling deep drilling into more extreme environments over longer periods. The GeoVolve HAMMER is a simple plug-and-play device which connects directly to the bit in any bottom hole assembly configuration. It is very simply powered by the flow of conventional drilling fluid, yet introduces a negligible pressure drop and no restriction to flow. It features an uninterrupted through-bore. Operating automatically and autonomously, it requires no complex surface control systems, and does not rely on compressed air or cross-flow fluid systems. GeoVolve is designed as a hostile service tool, and as such, is made without elastomeric seals for use in ultra hot well environments, particularly geothermal wells. HydroVolve is collaborating with several partners in both the gas and oil, and geothermal industries to fast-track development of the GeoVolve HAMMER.

22 MARCH 2022 WorldWide Drilling Resource® The “Idiots” Corner by “Billy Bob Smith” Retirement: Withdrawal, departure, leaving, starting over, ending. Here’s the official definition: “Retirement is the withdrawal from one's position or occupation or from one's active working life. A person may also semiretire by reducing work hours or workload.” Here’s my definition: “When you are tired of making other people rich, working long days and years to pay off your kid’s debt, or you finally get to do what you want to do with your life and not let everyone else tell you what you can and can’t, should or shouldn’t do, etc.” I had a more stupid definition, but I thought many of you might be looking forward to your final weeks, months, or year this year - so I would try and be respectful. Having said all this, what are some of the really dumb things people can’t wait to do in their retirement? Here are just a few of the most stupid ones I have seen, heard about, or actually witnessed: , Play Golf all day every day. Go fishing all day every day. Play bridge all day every day. , Watch TV all day every day. Do nothing all day every day. , As a Hallmark Movie Junkie - YEAH - I get to watch that channel’s movies all day every day. , Hanging out at nightclubs where younger folks are looking to hook up with the opposite gender - yeah right. , Volunteering at nursing homes to keep old folks happy and having fun. , How about becoming a wedding crasher? , Starting a new career as an actor or actress to star on a new “old folks” show. , Move to somewhere you have always wanted to live - Montana, New Hampshire, or even Florida. , Reconnect with high school or college friends you haven’t seen in years - if they’re still alive or even remember you. I’m sorry, I’m starting to feel older just writing this stuff down, so I’ll leave you with a final thought: If you retire, you are still alive, so don’t start acting like you are dead or in your teens. Think about . . .

24 MARCH 2022 WorldWide Drilling Resource® Fishing with a Downhole Camera Adapted from Information by Allegheny Instruments When a drill string or bit breaks while drilling a borehole, or a pipe, equipment, or tool falls to the bottom of the borehole, drilling needs to stop so the items can be fished out of the wellbore. Although there are several tools drill operators can use for fishing operations, using a downhole camera can help efforts to retrieve drilling equipment, tools, and pumps that have dropped to the bottom of a borehole. Allegheny Instruments’ GeoVISION™ Nano camera is the smallest diameter production borehole video inspection camera made today. It is only 3/4 inch in diameter and is designed for use in boreholes as small as one inch in diameter and at depths up to 2000 feet. The Nano camera can be lowered directly into the well, or through a small-diameter pipe if there are multiple obstructions in the wellbore. Based on the visual observations of the objects in the bore, proper tools can be employed to retrieve the lost items. Much like the scopes or cameras used by surgeons in delicate operations, the Nano camera can be used during the actual retrieval efforts - just remember to remove the camera before pulling out the lost items! It can also be used to diagnose problems in operating wells. In 2016, a small community in Vermont noticed the production rate of its gravelpacked well dropped by 50% overnight, requiring the pump to run nearly continuously to meet the water demand. To troubleshoot the well without removing the well pump, Tri-State Drilling & Boring of West Burke, used their Nano camera to visually assess the well condition. The video revealed the 10-inch well screen was twisted with the bottom portion of the well filled with pack material. The unique ability of inspecting the water well with a Nano camera helped solve the mystery behind the reduction in productivity. The Nano camera has standard NTSC resolution with an aspect ratio of 4:3. Illumination is provided by six high-intensity white LEDs. This camera is rated for use up to 1000 psi and can be used with light-duty, heavyduty, and deluxe winches. It can also be used with the Nano Auto Rotating Mirror to allow a side scan of the borewall. The Nano Auto Rotating Mirror can be set to rotate continuously or to rotate approximately 20 degrees, pause for a few seconds, and then continue rotating. This pause allows maximum resolution for recording video images. WTR You can use a downhole camera to inspect damaged well screen. Opportunity Knocking!
