Rigging up the Wireline

Rigging up the Wireline

And, I am back, with one hell of an experience. During May-June 2010, or rather ending yesterday, I was a Summer Intern or a Vacation Trainee at the Rajahmundry base of the Wireline segment of Schlumberger.

For the yet to be introduced, Rajahmundry is a place in coastal Andhra Pradesh, India. It is the place, along with Kakinada from where the oilfields of the Krishna-Godavari(KG) basin are operated. ONGC has a base here too.

And, Wireline is basically sending a bundle of sensors, called "Tools", the bundle being called "Tool-String", down an oil-well to find out the parameters of the well.

So, a lot of things happened, which i had never imagined would ever happen in my life. The prime points being working in a shop-floor of one of the most happening industries of the world. Visiting an oil rig, at the mouth of the Godavari, and making a temperature measurement box which is being used for the operations.

To begin with, i'll give you a list of the things which I did in the first 6 days : - Washed a set of oil-covered tools with a big water gun, applied grease on giant screws, cut through 2 inches of wood with a hacksaw, lifted 70kg cylinders, stood 3m from a radioactive source, used an iron spanner on a giant magnetic tool and got it stuck to the tool :D, pushed 150 kg trolleys all around the shop floor, wore 3 layers of clothing + a helmet + woollen gloves + thick safety glasses out in the sun at 45C, Got into a huge Renault truck, scrubbed large cylindrical tools, de-rusted king-sized bolts, helped debug a 12-foot long circuit board.

So, i bet you must have got an idea :)
Anyways, afterwards, this seemed to be totally normal. The most common thing done was connecting tool strings for the engineers to simulate, check and calibrate. It was really awesome to work with such big things.

Fortunately I had the company of one of my friends, and dep-mate, Debotosh. Was great, helping each other at times of need :)

And, a visit to an Oil Rig was simply one great learning experience.
In the wireline segment, the rig operation is basically sending a tool string down to the well. For that, 2 pulleys are attached to the rig. One at the rig-floor and the other at a height of about 300 feet! This is called a Rig-Up. It was just awesome to see the pulley going up and the tools being sent down. And, again observing from the control unit, how the cable-drum was being controlled. :)

During the rig visit, got the chance to ride on the Schlumberger truck, custom-made by Renault. We were probably on one of worst roads of India, deep inside the villages of AP, and it was really smooth. Even the seats had air suspension in them!!
I also saw my first ever HIMYM episode, at the rig, on the engineer's lappy, inside this truck, waiting for a crate of explosives to arrive!

Must say, an experience of a lifetime :)

The next part, was making a project. For certain tools, the engineers have to cool it down with liquid CO2 before sending it down the well. So, my job was to locally make a temperature measurement box. Not the simple circuits we use in labs. But, one rugged, shock-proof, weather-proof, humidity-proof temperature measurement box! Trust me, that was one hell of a job. And, fortunately, i could design and complete it within a period of 4 weeks!

Apart from all that, made a lot of friends. Met people from across the world!

In fact, to list out the nationalities I met :- Lebanese, Iraqi, Jordanian, Egyptian, Japanese, American, Mexican, Indonesian and of course Indian :P.

What do they actually want?

The last post was a bit hasty. But, this one will be in more detail.


The question right now we face is, how do we tackle this whole situation? The continuous terrorist attacks occurring in our country, every few months have left a scar on everybody's mind, a dent on the country's ideology. After all, who is carrying out all this? And, what do they really want?

The answer to "who" is obviously the terrorists, the Mujahideen, the radical islamic terrorists. Apparently they are termed as "Indian Mujahideen". And, obviously, help and support from people across the western border is always there.

After all, what do they really want? What will they get by doing such acts of cowardice? If they really want to fight, they can simply come up and face the army, and take over the country. But, apparently that's not what they want. They hide from the forces and carry out blasts in the middle of busy market places. That may be because they want to show that they are the "hidden killer". They probably want to terrorize the minds of the people. But, such terrorism remains only till the news channel shows up, and it is forgotten. And, in the end, what will they achieve by terrorizing our minds? They can't topple democracy by doing this!


Do they want what they fondly call "Azad Kashmir"? Well, they need to face the 1.3 million strong Indian army and other military forces for that. Doesn't seem to be feasible. So, in the end, what do they want??


Do they have a message to convey each time they carry out an attack? Do they want to derail the so called "peace process"? Do they want war between the two neighbours? What will they get by that? The word "peace" never comes into mind when dealing with pakistan. What will they get if there is a war? Will they get the satisfaction that "something" is happening? Will they see Jihad in that? There have already been 4 wars, 1947,1965,1971 and 1999. All have been fruitless on their side. Is it their anger of humiliation in these wars which is showing up in these attacks?

The question remains unanswered. We can only estimate and speculate. Nothing else. I would love to hear comments on this.

Let us take ourselves back to pre-1989 periods. Governed by Zia-ul-Haq, he was the man who brought all Mujahideen into pakistan, and called them to fight, against the Soviets and against India. His efforts in building up the Jihadi infrastructure has bore fruit, and terrorism is there everywhere around. He might have had a different vision than what is happening in the present day. He was a military General and a dictator, chief of the Pakistan military. He was one of the angered generals for sure. He was the one who pushed Islamic militancy into Pakistan. And, started a proxy war! Wait a minute,....Proxy War?? That was the time when militants were being trained for pushing the Soviets out of Afghanistan, and thanks to the Cold War era, he received a lot of funds from the US. That was used for training the Mujahideen, to fight a religious war against the Soviet Union. And, as Wikipedia says, the war left deep scars on Pakistan. It initiated and spread the Kalashnikov culture. Rather, the AK-47 culture. It is estimated there are 20 million fire-arms in Pakistan, out of 160 million people. Just imagine, every eighth person having a fire-arm! And, then, the pakistan army diverted the Mujahideen towards the Indian side, and hence the rise in Islamic terrorism in the late 90s.


Well, the conclusion is that the present day Jihadis have Pakistan Army and ISI backing. Now, lets take a look at the situation afresh.

In most countries, the State has the Army. But, in Pakistan, the Army has the state, as is visible from the repeated coups. That means, the army functions independent of the state functioning, rather, the army controls the state functioning. Put in simple words, the proxy war continues, but now against India.


Fast forwarding to the present day, politicians claim that the terrorists want to derail "peace talks". Well, the peace talks are being done with the Pakistani elite, who either have no relation with the army, or are simply their puppets. The probability of the latter being much higher.

So, the people who are attacking us, are also the people who are accepting "peace talks". And, as has been seen in the past 2 decades, it will as obviously be broken, because the anger and attitude of the Pakistan army cannot be contained by simple "democratic talks"!

And again, we come back to the question, what do they actually want?

The people accepting "peace talk" proposals are the same people derailing them. So, where are they heading to? Are they in a make-break game, and get the joy of killing a certain number of civilians? Or, are they upto a War?

Well, pakistan army is one army which has been scarred by the wars with India before. They might be wanting revenge.


It is still totally unclear, after all, what do they actually want?

Haven't we had enough??

I wouldn't like to say much.

But, I would be glad to allow the statistics to say it out.

December 2001 : New Delhi, Parliament, 12 dead.

September 2002: Akshardham,34 lives.

Aug 2003: Mumbai, Gateway of India,46 dead.

October 2005: New Delhi, Day before Diwali,3 Bombs, 62 Dead.

December 2005 : Bangalore, IISc campus, 1 killed, 4 injured.

March 2006: Varanasi, 2 bombs, Train Station and Sankat Mochan Temple, 20 dead.

July 2006: Mumbai, 7 Bombs, Local Trains, 200 dead, 700 injured.

September 2006: Malegaon, MH. 2 bombs, 30 dead, 100 injured.

February 2007: Samjhauta Express, 2 bombs, 66 dead.

May 2007: Hyderabad, 1 bomb, 11 dead.

August 2007: Hyderabad, 2 bombs, 32 dead.

October 2007: Ajmer, Ajmer Sharif Shrine, 2 dead.

May 2008: Jaipur, 8 bombs, 65 dead, 150 injured.

July 2008: Bangalore, 2 killed.

September 2008: New Delhi,26 dead.

November 2009, Mumbai, 173 Dead

February 2010, Pune, 8 dead and counting

Adding up the above numbers, it comes up to 764.

The case is not about simply the numbers. After all, how long can we sit like stones and practise restraint? How long? How long can we just stay back like a coward and practise non-violence and ahinsa?? How long? Did it have any effect in the past 60 years? NO!! How long can we be a "peaceful" country and get our own citizens killed at the hands of terrorists across the border.

Continuing what I mentioned, the case is not about the numbers, it is about how much we have been blown apart. The militants have reached right at the heart of the country's financial capital, at the cradle of the most sacred Hindu city, at the seat of the most sacred Islamic shrine, at the most revered Educational Institution,at the nodal point of the country's democracy, at the busiest market places, at all places where normal people go.

After all, how long can we keep facing the blows and continue with some crap, which the politicians fondly called "peace talks"?

If our innocent people are being killed, why do we sit silent and keep watching? And why do we still have cricket diplomacy with the killers? Why do we still keep on employing the method of "peace talks" which has repeatedly failed over the last few decades, when we know that they are obviously going to be broken???

The country seriously needs a revolution.

ROBOTIX 2010 : Of Standards, Difficulties and Numbers

Well, we have another year of ROBOTIX, Tenth year that is. We started out to push ROBOTIX as a platform to promote free thinking among the engineering fraternity and let technology break free from the chains of department labs and examination halls.

To be honest, all my expectations were fulfilled in this particular ROBOTIX. There have been 9 ROBOTIXes before this one. What change have we achieved? As has been explained by several of the cordis, alums and very recently by Golu, we have achieved a lot.

It started off in 2001, with a meagre participation, all in-house. The focus at that time was improvement of quality and quantity. Things were quite hazy and people were confused, but determined to make it grow. Growth meant two things, quality and quantity. Things went on till we had some 30 odd teams in 2004. Then in 2005, TRS entered a new phase. Enter Aneesh and Golu. TRS was officially formed and recognized under gymkhana. The concept of a "junta event" was introduced. For the unknown, "junta event" was one particular event which was relatively easy, and involved maximum people's participation, and sometimes entertained the on-lookers.

Year 2005 : That increased the participation to 220 teams in 2005, totally unexpected. That was the time when exponential growth in participation began, and it did begin with a roar. That meant more and more people were making bots. Taking the logic further, that meant that more people have started thinking freely. That was a positive sign and we started pushing for more participants.

Year 2006. Enter Anant Choube. While publicizing for ROBOTIX, we heard complaints from the colleges we visited that unfair measures were being used, with usual complaints like partiality etc. So, Anant made up his mind that ROBOTIX 2006 will be participant-friendly, and the participant will be rewarded for his effort. That was aimed at cultivating a good image of ROBOTIX among the general junta. We had something around 280 teams in 2006.

Year 2007 : Last year's participant-friendliness resulted in a surge in the numerical participation, with 550 teams coming to KGP for ROBOTIX 2007. Along with all this, the standard kept on improving, though not as fast as the numbers grew. This year saw some of the legendary events such as Grid Navigator, which became standards for the subsequent years.
Enter Aamir, the man who had pushed technicalities to a new zone.

Year 2008 : This is the year i saw ROBOTIX for the first time, an awesome experience. The numerical participation escalated to more than a 1000 teams! Honestly, the team seemed to be overburdened. The participation in the autonomous event Robo Relay was so large that it was termed as the first autonomous-junta-event! It was for the first time an event had a participation number as big as 350, as seen in Terra Ranger. The numbers were quite impressive, but there were several realizations which we had to wake up to. That was the year when we realized that there was no point in increasing the participation. We had to limit the participation. By then, we realized that we had the power to attract 1000 teams to KGP, whenever we wished. So, the focus was bound to change. The focus is now on technical advancements. Giving the people more challenging and real life problem statements in the field of robotics was our main task at that moment. Something similar was said when Aneesh visited the campus. My views on that can be viewed here. Something which Sassy pointed out, and felt bad about, was that it had become a certificate mela. People coming with simple differential drives and asking for certificates.

Year 2009 : We had come to a new phase. The focus now was on the quality of the teams. The quality of the robots they made. Simple differential drives were to be killed. A certificate policy was to be decided so that only the deserving teams get certificates. This changed a lot of things. The legendary 8Mile was introduced. Estimates said that the participation would decrease drastically. 8Mile was tougher than any other event our country had ever seen, or rather thought of. Honestly, it was unimaginably difficult. Next came 12 Doors Down, much tougher than last year's Robo Relay. Plus, the mechanical events were naturally tougher than those of last year. We were forecasting drastic reduction in the participation.
But, clearing away our fears, due to the simplicity of wEDGED and #mEsh, several teams arrived, with the number being at 800.


Year 2010 : Enter my batch. We felt that improvement of difficulties was imminent. Hoping that 8Mile would some day reach DARPA levels, we decided to continue with the legendary 8Mile, we elevated the difficulty and renamed it to 8MileX, to mark our 10th anniversary. We introduced the first ever underwater event, held in a swanky perspex tank, eXplore. As another first, we introduced the first ever 10-hr robot-making event, TribotX Championship. And, the previous two were probably the first ever manual non-junta events :D. Also, we introduced the first ever autonomous event requiring special mechanical skills, in other words, the first ever "mechatronic" event, Xtension. Along with all these, we had Xplode, where we experimented with metal detection with the metal embedded beneath a wooden surface.
Considering the difficulty of the events at present, it would be insufficient to call this as phenomenal! The participation numbers went down to something around 450 teams, but the standard improvement was extraordinary!

Apart from the standard, the event was totally chaos-free, felt immense happiness as a head. Commanding a fantastic team, where everyone put one's best, to make this possible, it was simply superb.

Also, something which I hadn't noticed, but pointed out by Golu, that all the events had some or the other significance with respect to the real-life problems faced by people. These turned out to be standard engineering problems. Things like automated vehicle guidance, mine detection and avoidance, instant bridge construction, underwater rescue and even material sorting; all were implied in the events.

We have started going on the path of technological improvements in ROBOTIX. I hope this is the beginning of a new phase, where old mindsets are replaced by new and radical ones, where people aren't afraid to think and aim high. Where Standards matter more than Numbers.

I personally feel we are treading in the right direction.

All I can do now is hope that the future batches will go in the right direction.

All the best to my dear sub-heads and members.

And, never forget, as Swapnil says :

eNJOY!!
