PRD Interim – April 2021

MD Desk

Greeting to all my team – the start of our summer months has brought back the deadly virus that has been ravaging our world. I urge everyone to stay indoors after work and follow the protocols of washing your hands and wearing a face cover at all times. Like a meme said with pictures of the devastation caused by the pandemic looks like “we are in the Endgame now”. India has seen a massive spike in the COVID-19 cases even though there has been a good recovery rate. It is disheartening to see the loss of so many people.
I pray to God that everyone’s in relationship and collaboration with PRD, Our colleagues, Suppliers, Vendors, Stakeholders, and most importantly our customers are kept safe with the protection of the almighty, May all their families be protected as well. Amen

On a positive note – in the near future PRD rigs will be executing their massive Planned changes in terms of expanding our marketing efforts, with the appointment of our Sales and Service Head – Pan India we look to see that our product marketing a sales is lead by a strong-minded individual who is capable of expanding our growth exponentially in the market, the key factor here is the enhancement of our Customer satisfaction with a brand value-driven product environment.
Even on the global stage, we are having Challenges when comes to sales and marketing our team has made some massive changes in their structure to accommodate all sales, service, and Aftersales for better management and generation of more orders as there are many restrictions and policies in international travel which is making it hard for our team to consider a GTM as a strategy. So the team has made the necessary changes in terms of adapting to entry strategy in new markets with critically appointed Product enthusiasts who ensure that products are refined to their standards and operational practices, this also goes with our hyper customized Customers Service experience.
Wish everyone good luck and I continue to urge and insist everyone. To make these changes in your lifestyle to adapt to the new normal of the Pandemic situation.
A thousand May fall dead beside you, and ten thousand all around you. but you will not be harmed. – Psalm 91:7


Happy to inform all that our domestic sales has crossed the century mark in terms of units in the financial year 2020 – 2021 for various drilling applications.
This achievement is contributed by consistent efforts put by Domestic sales & service Team fully supported by Backend team.

Few Important Milestones
1. We delivered record no of 65.Nos of PRD HC 500M to DSI segment alone to domestic Customers.
2. Appointment of M/s. Adhi Vinayaga ELGI Dealer as our representative to cover aggregate TN and Kerala Aggregate market.
3. Launch of PRD GD4 Geotechnical Rig for Soil Investigation and supplied to L&T – High Speed Rail Project first time in India
4. New Branch opening at Khammam, Telangana – to cater DSI customers with on time spares support.
5. First to mount Autoloader Rig on AL BSVI Truck in India

We would like to thank our beloved chairman Mr. T.P. Thangaraj for his guidance and our Managing Director Mr. T.T. Paranthaman for his continuous encouragement and support to make the above achievement happening.
Let’s welcome the financial year 2021 – 2022 with more aggressive growth by improving our reach and support.


Emergency assembly point/safe assembly point is a location where workmen/staff/visitors can gather in an event of fire/leak/explosion or any other emergency event in a safe designated area. It is designed in such a way that it is 50 feet away from the factory and its buildings. It’s been designed according to ISO 7010 – E007 standards. The assembly point is influenced by the following factors, Size, Access, Backup, Location, Distance, Other dangers, etc., This assembly point is made for the benefit of the employees’ company such that no damage should occur to the people in case of any emergency. Drawings are the international common language for engineers whereas safety is the international common language for all people. An engineering marvel cannot be done without considering safety. Safe practices will lead to a sustainable environment. This kind of safe practice will lead the company to the next level and give hope to the employee of being in a safe environment which in turn gives a happy workday.

Paranthaman Exporters is happy to announce that an Emergency assemble point has been designated inside our premises in case of any incidents, our staff and workers are yet to be given training on evacuation to accommodate the safe and orderly process of evacuation. PRD aims to be certified under ISO 450001:2015 in the near future.
Kudos to our Factory Manager – Mr.UmaShankar and team for implementing the assembly.


Drill pipe sticking and recovery
–  Causes of stuck pipe/rods
– Differential pressure sticking
– Key-seat sticking
– Recovering stuck pipe

Causes of stuck pipe/rods
Getting the drilling tools, drill rods, or pipe stuck in the hole is a fear that most drillers share. Getting stuck leads to much lost drilling time as efforts are made to free the stuck tools. The forces exerted can lead to drill string failures. The problem then becomes more complex with a ‘stuck fish’ in the hole.
Often the driller is warned of impending sticking by:
– increasing drag as the drill string is raised or lowered
– increasing torque
– vibration during drilling.

These increases in resistance to drill string movement are indicators of a developing problem. Stuck tools surely represent a problem. But they are also an indicator or a result of the actual downhole problem. The real problem to be addressed is the deteriorating shape, cleanliness, or stability of the hole. Downhole problems that can result in stuck tools fall into two groups:

Fluid problems:
The wall cake building characteristic of drilling fluid can allow thick sticky wall cakes to build up. This can be caused by using a mud weight higher than that required. Hydrostatic pressures may then act to hold the tools in the wall cake

Mechanical problems:
There are many ways of forming  a mechanical bind between the walls of the hole and the drill string:
– pulling into a key-seat that has formed in a dog-leg in the hole
– cuttings or cavings building up a solid wad around the string
– problem formations swelling or otherwise moving into the hole, and running the tools into an undersized hole
– running the tools into the bottom of the hole or into a ledge and distorting the tools
– cementing the drill string and ‘burning in’ a diamond bit

Three mechanical problems are depicted above:
1. Cuttings or cavings have formed a wad around the string in the hole.
2. Bit cutters have spread out after impacting the hole bottom for some time.
3. The bit has become wedged in an undersized hole or mud ring.

As illustrated, downhole problems that lead to a stuck drill string are always worse when the hole is crooked or not vertical:
In inclined holes, when mud cake lines the hole, the drill string can become stuck if it presses into the mud cake on the low side or bottom of the hole wall, and a casing failure may result.
In crooked or dog-leg holes, a drill string can become caught below a bend, causing problems. The risk increases with the severity of the dog-leg. In this situation it is difficult to pull the string because of friction against the wall at the bend.
When drilling in ‘crooked hole country’, a driller may have resign himself to having some bends in the hole. He should therefore concentrate on reducing the curvature and avoid sharp bends or dog-legs.
Good drilling practices, frequent mud testing and treatment, and close monitoring of the cuttings and fluid return will allow the driller to recognise early indicators of downhole problems. The driller is then in a position to prevent the problems developing or he is able to solve them quickly, before the drill string becomes stuck.


Space is getting messy. The amount of debris orbiting the Earth keeps growing each year, disrupting satellites and occasionally putting astronauts in harm’s way.

Space junk has been a growing problem for years as human-made objects such as old satellites and spacecraft parts build up in low Earth orbit until they decay, deorbit, explode or collide with other objects, fragmenting into smaller pieces of waste.

New Effort To Clean Up Space Junk Reaches Orbit
Space startup Astroscale has launched ELSA-d, the demonstration mission for its End-of-Life Services by Astroscale (ELSA) technology, which aims to dock with, and then safely remove, orbital debris. Astroscale’s demonstrator package includes two separate payloads: a servicer that represents its future production spacecraft and a “client” satellite that’s meant to represent the debris satellites it’ll be de-orbiting on behalf of customers in the future.

According to a recent report by NASA, at least 26,000 of the millions of pieces of space junk are the size of a softball. Orbiting along at 17,500 mph, they could “destroy a satellite on impact.” More than 500,000 pieces are a “mission-ending threat” because of their ability to impact protective systems, fuel tanks and spacecraft cabins.
And the most common debris, more than 100 million pieces, is the size of a grain of salt and could puncture a spacesuit, “amplifying the risk of catastrophic collisions to spacecraft and crew,” the report said.
According to NASA, cleaning up space — and addressing the risks associated with debris — depend on preventing the accumulation of more waste and actively removing it.
The development of other cleanup technologies has been underway for years. In 2016, Japan’s space agency sent a 700-meter tether into space to try to slow down and redirect space junk. In 2018, a device called RemoveDebris successfully cast a net around a dummy satellite.
The European Space Agency also plans to send a self-destructing robot into orbit in 2025, which the organization’s former director general has referred to as a space “vacuum cleaner.”
