PRD Interim – Nov 2021


Dear folks, November was a good start to the end of the year. We have struggled and have come out of the flying colors yet again. As we all know the struggle, the chase, and the victory is not yet achieved. We are waiting for us to climb the summit and cement ourselves at the top. Hope we reach there by end of the year. The Summit being achieving our Targets and cementing in your Strategy.

The markets have become very competitive especially in the water well segment. In all markets, there is as urge of Indian drilling companies venturing into other profitable drilling territories. This creates instability in the regions, where the unorganized Indian driller as a new entry to start driving low-cost drilling rates and unethical practices. We are trying new strategies to help us ring-fence our market share. We have started building locally made cabins for these particular sectors. We are going back in our development currently but yet moving forward to protect our market interest in this water well sector.

In the global front, we have successfully completed the validation of our new rig. We have planned an eventful launch in Australia in the following months which will help to push our brand and technology into the global market. Kudos to all our team in collaboration for the successful output. I can guarantee the team with confidence that the PRD WW18 will be a huge success in the Australian Market and other developed countries. All we need is good service and reliable performance from the machine.

During the month of October, there was a plan to organize a training program for compressor engineers across all our branches. This plan was executed on 5th October as the 1st service training in the ELGi compressor for Regional Service Engineers.

As you know that PRD Rigs has established an extensive service network across Africa. This means that we need to constantly improve our services with constant improvement in the products especially in the compressor sector as we move from the B2B series to the compressor PG series. To enhance the services reliability, our PRD service team headed by Mr. Karthikeyan organized this training in collaboration with the ELGi service team.

Two representatives from ELGi team Mr. Gopinath – Service Engineer and Mr. Sampath from Aftersales gave 2 hours of extensive training on the compressor model importantly the difference in the compressors. This was well received by our service technicians and engineers worldwide. One of the key features was explained the new water yield kit in the PG series of compressors. This was the new feature that was introduced by ELGi which enabled the compressors to maintain their drilling efficiency even during high water yield in drilling, the setting, function, and work was explained.

The training was attended by Mr. Sathish from Kenya, Mr. Manikandan – Operation Head from Ghana, Compressor Service Engineer Mr. Suresh and Compressor Service Technicians, Mr. Gokul from Guinea, and Mr. Kalai Kumar from Sri Lanka. Kudos to the team for the arrangement and execution.


Air core drilling uses three-bladed steel or tungsten drill bits to bore holes into unconsolidated ground and is used when safe and clean removal of sample material is paramount. Air core drilling is an inexpensive method of exploration drilling that can be employed when safe removal of sample material is paramount. Where possible, it is preferred over RAB (Percussion rotary air blast drilling) drilling and unlike the diamond drilling method, which withdraws a small diameter core of rock from the orebody, air core drilling is much faster and more cost-effective.

As the name suggests, air core drilling relies on compressed air to flush cutting samples out of your drill holes. This enables the safer collection of samples without unnecessary damage to the surrounding area and results in a more effective analysis sample.

Where is Air Core Drilling Applied?
 Air core drilling is a valuable method of drilling for organisations looking to reduce the risk of sample cross-contamination. It’s commonly used in first-pass exploration drill programs on unconsolidated ground, with an optimal depth of up to 300 meters.

Advantages of Air Core Drilling
Air core drilling has clear advantages over other drilling methods.
–  It eliminates the need for casting holes. 
– It provides a more representative sample of material. The nature of the expulsion of the materials provides samples that are easier to analyze. 
– Delivers safer sample removal. Due to its reliance on compressed air injection, air core drilling involves less damage to the samples, when compared with blast drilling.
– Boosts efficiencies and reduces costs. Air core drilling is an efficient method for removing material. It enables real-time sample collection, which speeds up drilling rates, resulting in reduced field costs. Air core drill rigs are also lighter in weight than other rigs, meaning they’re quicker and easier to transport.
– Less chance of cross-contamination. As compressed air is used to flush the cuttings through the inner tube, there is less sample pollution than other methods.

Disadvantages of Air Core Drilling
While there are many advantages to air core drilling, it also comes with disadvantages when compared to other methods of drilling.
– Air core drilling can be slower. While air core drilling is considered more efficient, the drills typically operate at a slower speed than other methods, making the drill   process itself slower.
– Depth limited. Depending on a number of variables but predominantenly available air pressure, air core drilling is usually limited to depths of 50-120m.
– Fresh rock penetration limited. While air core drilling is able to drill through cap rock at the top of a hole using a hammer or tri-cone roller, air core drilling is usually unable to penetrate fresh rock.

What’s The Diff­erence Between Air Core Drilling and RC Drilling? While the equipment used in air core drilling and RC drilling is similar, the mechanisms involved are different, so each is useful in different situations. Both involve the use of compressed air to flush out samples. However, air core drilling is ideal where unconsolidated ground is present. RC drilling on the other hand, uses the added element of concussive force to power the drill bit, pulverising the rock in its path. This makes RC drilling ideal for harder ground. RC drilling is also typically able to achieve greater depths, and better-quality samples, than other types of drilling.


The third unbundling is reshaping entire industries, as businesses break down enormous operating structures into smaller, more agile and innovative units. Right now, a third unbundling is underway in every industry from entertainment to enterprise, where the world’s most innovative businesses are increasingly being led by the desire to serve customers quickly and conveniently – directly to their mobile phones, TVs and wearable devices. Globalization’s Next Big Thing: Globalization’s Third Unbundling The three-cascading-constraints narrative plainly admits the possibility of a third unbundling, if face-to-face costs plunge in the way coordination costs have since the 1990s.

Two technological developments might provoke such a plunge. Really good substitutes for people crossing borders to share “brain services” is the first. Such technologies, known as “telepresence,” are not science fiction. They exist today but they are expensive. The second would be the development of really good substitutes for people traveling to provide manual services. This is called “telerobotics” and it involves people in one place operating robots that perform tasks in another place. Telerobotics exists, but it is still expensive and the robots are not very flexible.

Despite the benefits of 21st-century globalisation, salaries and wages are much higher in rich nations and there are billions of people who would like to earn those wages. They are, today, unable to do so since they find it hard to get into the rich nations. If technology opens a sluice gate that allows these people to offer their labour services in advanced economies without actually being there, the impact on jobs could be dramatic. The relaxation of the face-to-face constraint may materialise via telepresence and telerobotics, as labour is made mobile by robots allowing people to offer their services remotely. In a nutshell, the next radical change in globalisation is likely to involve workers in one nation undertaking service tasks in another nation. Hotel rooms in Oslo could be cleaned by robots controlled by Philippine-based workers. Security guards in US shopping malls could be replaced by robots driven by someone sitting in Peru. The possibilities are only limited by the imagination.
