What are the Drilling Techniques Used in Ice Core Sampling?

Drilling on land has its counterpart. If drilling work is to be carried out on a blanket of ice, an ice core drilling process can be employed. There are several drill techniques currently used for this purpose considering the fact that drilling through solid ice is a pretty arduous task. 

Most ice drilling projects involve getting through the oldest ice. Hence, drilling through the ice to reach its core, near the ice divide, is done. Ice divides are usually located at some distance, far away from the ocean and research bases.

For purposes of education on this subject, here are some of the employed drilling techniques used in ice drilling. 

The Hand Auger

Of all the drill systems available in the industry today this, by far, is considered by those involved in the business as the simplest and the lightest of them all. It is capable of collecting 74 mm diameter core from the surface of 10-meter firn (firn – this is a phase between ice and snow). The drill itself consists of an ice-cutter containing a drill head that takes on the job of drilling into the firn. The core barrel, responsible for holding the core intact upon pulling to surface, connects the rods so they will extend to a depth of at least 10 meters. 

The entire system can be held inside 2 relatively easy-to-carry boxes, each box weighing about 80 kg. This allows for easy deployment with, say, a small aircraft. 

The drill will cut away a ring off the firn while rotating, and by virtue of the natural gravity, it will descend deeper and deeper. And as it goes deeper, it will fill the central cavity with an unblemished firn core. The operator can pull the core barrel up to the surface when it is already full. After 15 “runs”, it will have a total of 10 meters long and 74 mm diameter firn core would have been brought to the surface. The cores, upon completion, will be fitted together, labeled, measured. Later on, they will be packed inside custom ice core boxes, ready for shipping back to a lab for further analysis.  

The Shallow Drill 

In terms of their sizes, a shallow drill system is considerably heavier, larger, and more complex. Deploying a complete setup, together with spares, tools, and a power generator system, everything will weigh around 800 kg. The weight is estimated to go around 10 times the hand auger. You can place a shallow drill on 2 Nansen sledges and it can be towed using a ski-doo. A small plane also can be used if you want to transport them to what can be considered as less accessible drill locations.  

Much like the hand auger, this type of ice drilling system collects at least a minimum of 74 mm diameter core, starting at 2 meters below the ground surface. As for the descent, it would be a maximum of 350 meters down. 

We qualify this drill technique for ice core as an electromechanical drill, raised and lowered by an electrical winch. The surface’s tilting tower will help in easing drill handling and core extraction.  

As for the drill head and core barrel, they share a certain level of similarity to the hand auger on this aspect. However, the core barrel is usually contained within another outer core barrel, but this will never rotate, though, while drilling work is in progress. Vertical grooves found lining the outer core and thick spirals on the outside significantly help in transporting the chippings of drilled ice to the core barrel top part. From here they will be contained inside a plastic insert at the top of the core. The drilled core segments measure up to 1 meter in length.  

Success in ice core drilling lies in the effective use of known drilling techniques. The most widely used ones took several decades to develop and were built based on the experience, knowledge and hard work of many people. Different kinds of drills may be required when working on varying drilling depths since conditions are likely to change with respect to depth through the ice cap.  

Why It Is Important to Keep A Machinery Maintenance Log?

Every business, no matter which sector it belongs to, depends on the use and capacity of the equipment. The downtime or unavailability of devices prospects to time wastage and possibly lost product sales. This is exactly why taking excellent care of the machine should be a high priority.

Nevertheless, it can be challenging to be sure that all these vital assets are maintained and inspected as frequently as necessary. It’s essential to keep a machinery maintenance log for many reasons.

Why is Machinery Maintenance Log A Must?

1. It raises the resale price of the equipment

Proper upkeep and tracing of the gear upkeep log help the equipment of yours to work in optimum condition. Keeping a record also attests to be helpful when you opt to upgrade your current gear with the latest versions.

What specifically impacts the resale choice for a customer is learning regarding the care place into the gear by the prior owner. Keeping data of repairs as well as maintenance assists to outline a clearer image for the customer about the interest offered to the property to always maintain it in the very best feasible condition.

Keeping a revised product upkeep history may seem complex. Nevertheless, the equipment tracking program makes it easy and simple. It will keep putting in specifics of each and all your gear goes through, therefore maintaining the repairs and maintenance files updated on all of the occasions.

Moreover, well-documented maintenance raises the worth of the old gear as in comparison to other used gear which does not have any maintenance records. In order to capitalize on resale value, consistent and complete history of anything, such as fix schedules, use logs, and upkeep records, is important. The records help increase the buyer’s trust in the seller’s assets.

2. This saves the initial costs

Having a comprehensive equipment upkeep log tells you once the time is best to change the machine. This, in turn, will help money is saved by you. The information which is gathered through time unveils displays of disappointment, spending, and fix.

Let us think a piece of gear is likely to break down every two weeks. Such costs $2500 per season to restore. Rather than tossing money away on the maintenance of its, it is going to be much more cost-effective to merely change that computer for $4000. This is not to mention, purchasing a brand-new device is going to come with equipment improvement along with a completely new warranty, therefore reducing costs as well as tools breakdowns.

On the flip side, with gear maintenance program you may also learn that upkeep is a great deal cheaper than really replacing the entire equipment. The lack of appropriate maintenance captures can lead to regular unexpected downtimes. Such downtimes will inevitably end up in skipping due dates, stopping the lines of production and holding employees idle.

In addition to all that, you also must spend technician’s overtime for such unpredicted disaster and the additional cash for immediate delivery of parts.

3. This identifies the trends across makes, versions, or components

The gear upkeep log throws some light on the typical trends in your gear across styles, elements, makes, workers and other things. The information on gear upkeep log tracked through a maintenance management formula spotlights which models and makers of specific equipment incur probably the lowest price per hour of possession.

On the other hand, there could be a portion of the exact same design of a machine that requires constant substitution after a comparable selection of mileage or hours. By doing this you can expect the replacement or maybe fixes are likely to be needed at the same period for the exact same design of gear approximating its benchmark.

The insight can assist businesses to understand the components which are essential in order to do repairs and replacement before any gear failure.

What Does Drill Rig Companies Look Into First When They Buy New Drill Rigs

According to the top global drill rig companies, drill rigs and proper drilling equipment are paramount to success in the oil mineral exploration drilling business. They are considered essential and must-haves, otherwise you will not be able to win in your drill project bids. And even if you win bids, you won’t have the means to complete your contracts. Since no amount of money is getting to your business coffers, you will realize that you would be struggling with the financial aspect of your business. 

Investing in a new drill rig can be qualified as a big, major decision to make. There are a handful of factors and variables that are likely to be impacted by this. But before you proceed, there is one important question that you need to deal with. “Am I going to make money with this drill rig? Or no?”. 

A reliable and dependable operations manager knows which of your valves, engines, or assemblies need immediate replacement. Usually, they also have an accurate idea of how much it would cost to rebuild the drill rigs in a fleet. If the amount of money to be used for the rebuilding process is in close range to the money one needs to shell out to buy or acquire a new drill rig, a full-blown audit should be underway, too. 

This will necessitate proper and thorough inspection of the drill rigs as well as an assessment of various spare parts that are in stock. Not to mention also is checking or validating maintenance records to obtain a more accurate cost comparison to get a drill rig working again.  

So here are some of the important things one needs to look into first before making any decision to buy any drilling rig for sale Australian products. 

New Technology

If your current drill rig is quite old, deciding to buy and acquire a brand new drill rig will give you a chance to drill more productively in the coming years. It is a fact, and this one’s not necessarily disputable, that newer drill rigs are more productive giving you more reliable uptime. In addition to all that, they also come packed with a handful of built-in safety features. This last one is in complete contrast to older rigs, though. 

With the current mine safety requirements that the authorities are imposing in the minefield exploration industry, a brand new rig will help you become compliant to those newly rolled out requirements where an older drill rig will just fail in. Sometimes this may even cost a drilling contractor the elusive contract award.  

Reliability

oil rigs

Used and much older drill rigs are more prone to breakdown more often, which is in contrast when you have much newer rigs instead. If downtime is a usual event in your drilling projects, it would be detrimental to your hard-earned contracts for drilling projects. 

If there is a slowdown on your productivity, this will induce your costs to pile up. It will also affect your rig uptime contractual obligations and drill rig repair. A well maintained and properly operated drilling fleet fuel up your productivity, but it will also prevent you as a contractor from getting evicted or written off a drilling project contract or site.  

Availability

The oil refining market these days is improving well and good. This signifies that every one of us can expect to receive much longer lead times, regardless if you are rebuilding something else or plans on buying new.  If the market is low or in decline trend, anticipate that inventory would be higher and lead times would be reduced. 

While the market is catching up and the number of contracts increases, the inventory would be lower and plants would be more preoccupied in building more drill rigs, and finally, there would be more lead times. Ultimately, lead times would be varying with respect to the manufacturer. 

Why Consider Buying New Drill Rigs? 

Devote time in considering all the options that you have. Assess your current drill rig fleet and ponder upon everything you might need to get done so everything will be well maintained and updated to keep your competitive edge intact. 

Is your drilling rig taking advantage of recent innovations and developments? Is it on par with the latest safety standards? If you can with your own eyes that repair works outweigh the returns, it is high time that you consider updating your fleet. 

The primary reason why you should make it a goal to buy new equipment versus used equipment for your business, regardless if you are in the oil mine exploration sphere or not, is to improve your productivity levels, further enhance safety, and for long term reliability.  

Industrial Machine Repairs for Long Term Use

Preventive and regular industrial machine repairs critical to the productivity and lifelong of huge machinery. The large machine makes it possible for conventional industries to figure on an outsized scale. Agriculture and mining are some of the worldwide industries that might not exist in the present time at the dimensions they are doing without the utilization of giant machinery to help their operations.

Advantages of Industrial Machine Repairs and Maintenance

Preventive maintenance keeps the price of the machine. Keeping equipment in their best good working condition prolong their life and keeps workers safe. It also guarantees the availability of the machine.

Early discovery of problems lets repairs to be made before things worsen. Machines that do not have to be taken offline for massive repairs will prevent production disruptions. Regular inspection, as well as analysis, are often used to calculate and stop component failures which can create safety dangers and machinery interruptions.

Scheduled equipment overhauls and preventive maintenance can help lessen the possibilities of industrial machinery interruption and thus reduces the risks that engineers face in onsite repairs. Accidents within the work environment are also substantially reduced.

The following are some tips for large equipment maintenance.

1. Keep Daily Use Records and Supervise Operation

Industrial equipment may wear down or breakdown and these are usually worsened by untrained use. Keeping records of machine use and supervising daily operations could pinpoint when and where the machine is getting employed by inadequately trained operators.

A new because of supervising the processes of giant machinery through GPS. This device traces movement and documents it in digital records that are arranged to be easily recovered. Problems are often discovered early, then breakdowns are often prevented.

2. Keep a Schedule of Proposed Maintenance

Parts break down, and wear is unavoidable. Establish projections for the expected lifetime of all components and replace them on schedule. Part replacement must be done by knowledgeable technicians.

Bearings are crucial elements of heavy equipment and should be easily broken or worn. Bearing casings need to be maintained regularly including inspection for corrosion and wear and replaced when necessary. A maintenance log should even be kept making sure regular checks aren’t missed and conformity is measured.

3. Grease and Clean Regularly

Working large machinery needs daily maintenance. Some elements, especially the moving components in engines, as well as power trains need regular lubrication. Other elements, like bearings and hydraulic lifts, need to be monitored and greased at the first sign of need.

Contamination could cause machinery failure. Water could also be a serious source of rust. Lubrication inhibits corrosion. Preserving the seals and substituting the filters would assist to keep lubricants contaminant free.

4. Check and Observe Components for Any Wear and Damage

A planned upkeep schedule could predict component wear. Be sure to inspect components on a regular basis to observe wear and stop breakdown. Components that possess to urge replaced before schedule might be a sign of a much bigger problem that has got to be detected.

Check pulleys, belts, and chains for their alignment, as well as condition. Inspect the sprockets and gears for any cracks, broken teeth and misalignment.

5. Safeguard Machine During Storage

Big machines need to be kept under cover every time possible. Motors, mixers, turbines and other machines need to be rotated regularly. Inspect unused machinery for condensation, rust, and contamination. Do not forget to ascertain all lubricant types. Oil-mist lubrication could also be an honest resolution for the harmful effects of humid and warm environments.

What Makes Sonic Drill Different from Air Mud Rotary Drilling?

When embarking on a brand new project, selecting what type of drilling method to use, whether you should go for sonic drill or air mud rotary drilling, is a decision of an undeniable importance. Choosing the right drilling method to use is critical as it does have a direct impact on the overall outcome of a project. 

There are several things that you will need to factor in when making a decision on this aspect such as what your project goals are, the schedule you mind to be mindful of, and lastly, groundwater and geologic conditions you will be working in. 

drilling projects

If you are slated to take on drilling boreholes, or you are going to work on a more challenging geologic formation anytime soon, sonic drilling and rotary drilling are likely going to be your top choices. 

Yes, that is going to be a tough call when you don’t know exactly what makes them distinct from each other.  

Sonic Drilling and Rotary Drilling Types: How Do They Work?

In rotary drilling, the borehole is being advanced by virtue of impact energy. This normally originates from below or above impact ground hammer you’re using and melding them all together with the rotation intended to macerate the drill formation. As for the cuttings on the drill formation, you can eliminate them from the borehole using only circulating water or compressed air. 

If the ground working conditions you are dealing are unstable, bentonite, a type of additive, can be mixed into the water. By utilizing air, the cuttings can be blown toward the catchment and funneled to a settling pit using mud or water. After this, the cuttings will be recycled to the borehole again.  

In sonic drilling, the borehole is advanced using resonant frequency vibrations. By this measure, the drill bit formations can be fluidized. Sonic head vibrations at the drill string move quickly up and down, with an intense drill bit vibration. 

Resonant “sonic” frequencies around 50 – 200 Hertz are audible and thus can be managed so you can make them fit the formation type you are dealing with. 

Rotation is optional and may be included when already dealing with harder or more challenging, difficult geologic formations. Sonic drilling is the most ideal drilling method to use when you are working on a drilling project that involves difficult  or very challenging drilling conditions.  

The Advantages And Possible Disadvantages of Sonic Drilling

The advancement of the borehole in sonic drilling is somehow comparable to rotary. The method offers a high level of effectiveness even in the most difficult of drilling conditions like boulders, gravel,  landfill or fill. It also works well in softer formations such as weathered basalt and sandstone limestone. 

When it comes to drilling waste, sonic drilling is likely to produce 10% less to what can be normally expected to be produced by rotary drilling. The vibration that is usually identified with a sonic type of drilling will ease the removal of casing intended for grouting projects.

Also by utilizing air, borehole wall smearing is alleviated to a great extent for environmental and geotechnical sampling. 

The surrounding formation in sonic drilling worksite can be disruptive to surrounding rock or ground formations. It also runs the risk of inducing new fractures to start appearing on a hard, unconsolidated bedrock which may hurt the structural or aquifer testing. 

This is among the reasons why sonic drilling is not very much practical option to use when your drilling projects involve dealing with hard bedrock or shallow borings. 

Sonic drilling, much like any other drilling method there is, generates heat. There are many geologic conditions where this can bring about changes in the moisture conditions or texture of the rock formations. Fortunately, there is a workaround on this side effect, and that can be seen when you make use of drilling liquid. 

A Primer on Sonic Rig Drilling

Sonic rig drilling is more of a rotary vibratory drill. It is a powerful  drilling equipment highly reputed for its high drilling speeds and its various features and capabilities in completing tasks, which also includes continuous coring. This is one of the drilling tasks to which other equipment will be struggling with or will have much difficulty in dealing in handling, but not with sonic rig drilling.  

What you will have initially is give you an impression of it resembling traditional air rotary drill rig. If there is anything distinct between the two of them, it is going to point you to the drill head. In terms of size, it is much bigger when put side by side with a standard rotary head. The head here is critical considering the fact that it is responsible for holding the mechanism required in facilitating rotary motion. The same can be used also in describing the oscillator, it takes on the responsibility of generating high frequency force.

Besides being pushed down and rotated, the drill bit will vibrate in an up and down fashion. These forces melding together makes it all possible to carry out a drilling process. This kind of drilling proper will proceed in the most seamless manner through many different kinds of geological formations even different types of rock.  

The oscillator is one piece of hardware that will drive the hydraulic motor, utilizing as well its out of balance weights so as to come up with and generate sinusoidal forces. Eventually, of it will be relayed to the drill bit. The drill string, on the other hand, will contain all these alternating forces and can be made possible by incorporating air spring. 

Varying frequencies will go so as to come up with conditions that are suitable for operation. Generally speaking, this come anywhere in the range of 50 to 160 hertz or cycles per second. For purposes of having a reference, in other countries the current household conditions would be alternating at 60 hertz.  

This range of frequency is still within the vibration of sound, that level of sound frequency which the human ear can still perceive and hear. Hence, the coining of the term “sonic drill” for this particular kind of rotary-vibratory machine

The Advantages and Disadvantages of Sonic Rig Drilling  

In sonic drilling, the advancement of the borehole is synonymous to rotary.  It has never failed on giving good impressions that it will indeed work and will be even more effective under difficult drilling conditions such as gravel, boulder or landfill. It can also effectively handle softer formations including sandstone limestone or weathered basalt.  

If you will compare sonic drilling to rotary method, you will come to realize that it will only produce about 10% less volume of drilling waste. Vibrations that are being produced by sonic drilling promotes the casing removal for grouting tasks. Air can be used in aid of alleviating borehole smearing for geotechnical and environmental downhole sampling and testing.  

It is inevitable for drilling activities not to create vibratory motions and this can result in disruptions or disturbance to the rock formations surrounding it. There is also a good possibility that it would cause new fractures  to appear on the hard and tough bedrock. When scenarios like this take place, it is likely going to harm the aquifer or the structural testing would be put to compromise.  

But if your drilling project involves making shallow borings only, sonic rig drilling may not be the best drilling method you need to employ. The same thing can be applied when trying to drill through hard bedrock or into some other tough drilling conditions. 

The drilling heat which the sonic rig drilling generates is capable of altering contaminant conditions, texture and may also have significant impact on moisture levels. However, it is comforting to know that  this side effect can be alleviated with the help of drilling fluid. 

You need to put on some protection on your sense of hearing the moment that   generation of sonic vibrations commences. Failing to do so or by becoming oblivious of this run the risk of exposing your ears to damage.  

Air Compressor Repairs and Choosing the Right Parts

An air compressor is a very powerful kind of machine that in this high-tech world is being utilized by people from different industries. It plays a great role in the lives of furniture makers, auto mechanics, etc. While compressed air is very important for heavy-duty tasks that will otherwise need great manpower, a compressor machine will need regular maintenance in order to ensure the right operation.

 

Just like with any other piece of equipment, it too can fail through time. There can be different reasons for its failure, like a problem with its motor, pressure, lubricant supply, etc. Such an issue should easily be remedied or else, you have to face air compressor repairs that can be very costly.

As soon as an air compressor stops to work and will require repair, you need to choose the right parts to use. The right repair parts would ensure that it will operate efficiently. Below are some tips in choosing the right parts.

They Need to Be Energy-Efficient

When buying parts for air compressor repairs, you will have the chance to purchase those that are energy-efficient. Since industrial air compressors make use of so much energy, you can expect higher energy bills. You may reduce this while maintaining efficiency in the facility by choosing energy-efficient parts like air compressor motor, vacuum pump, air compressor pressure switch, and variable speed drive.

 

The Should Match the Size of the Air Compressor

The air compressor parts that you need to choose should be appropriate with the use and size of your machine. You should not choose a bigger air compressor tank or an air compressor vacuum when you just have a smaller unit, or else, you will be overwhelmed with its system and usage or more energy than what is necessary. Also, you need to choose parts that correlate to the main use of the air compressor. An industrial compressor needs to have the most energy-efficient parts.

Don’t Just Opt for the Less Expensive Parts

In most cases, price is a big issue and many people just opt to settle on the least expensive options. But this should not be the case when it comes to air compressor parts. If you want your machine to function efficiently, then don’t just settle for what is affordable. Keep in mind that you will be getting what you pay for.

 

When it comes to parts, always choose the best quality ones. They need to be durable and reliable. Also, you need to buy air compressor parts from a reputable manufacturer and dealer that offers the best quality parts.
