During my first month as a young drilling engineer, I was sent for a hitch on a drilling rig at offshore Terengganu. My head was giddy with the vision of the awe I would receive upon stepping on to the semi, and impress people with my genius. After all, I had in my backpack my university TI82 graphing calculator, a thick company issued laptop, Excel pre-installed and I had made a point to read at least 1/3 of the Drilling for Dummies book during the weekend before. I entered the chopper cabin with hopes and dreams, and was sure that this was the start of an illustrious career.
Unfortunately, my earlier personal euphoria was gutted swiftly when I exited the chopper in a dazed stupor, trying to get my bearings on which was port and starboard, and wondering why nobody can just say left or right. Pointed to the briefing room direction by the HLO, I still managed to successfully go down the wrong set of stairs, while struggling to keep upright on non existent sea legs fighting against the rig sway. After finally being pushed impatiently by a fellow traveler to the right doorway, I sat gratefully in the front row through the safety induction, looking for the nearest waste paper basket in case my digested lunch decides to come up the wrong way. After the last presentation slide, I shook hands with the rig OIM and jolly old rotund medic, who then proceeded excitedly to show me locations of the galley, lifeboats and room. The images of the food being prepared in the galley, and the sight of tightly made top bunk in the four person occupied room, filled my mind with hopes for dinner and a deep slumber. Unfortunately those images were replaced with dread, when I was informed that actually my work shift had started. And like everyone else, especially as a newcomer, I would start my shift with the honour of meeting the drilling supervisor, aka the king of the rig, aka the company man.
Gingerly swaying in my shiny boots, I walked through the corridors and found the company man's office, eerily situated at the dimly lit end with the door half open. I knocked, and only silence greeted me. I knocked again, and a sudden bravado overcame my senses and I stepped in, because it occurred to me that technically, I was a company man too. Shifting to the middle of the room, my presence continued to go unnoticed by the man in charge. He was just sitting there on a rickety chair, gazing out to the rig floor through the smudged safety glasses and half opaque window. He looked very uncomfortable, hunched in filthy coveralls withered by what I assume to be continuous rig laundry and exposure to mud and sun, but he maintain his slouched posture in deep thought. I tried to calm my nerves and grunted a half swallowed "Hello, I'm Adrin, boss", and waited for him to respond. For another full 5 mins he continued his silent meditation, his deadlocked eyes just continued to stare into space. Then, his cracked lips moved ever so slightly, lisping the words no driller ever wants to hear, "We just stuck pipe". Unfortunately for me, I didn't know how dire a situation that actually was, and with the cheeriest voice I could muster, I said, "Oh good, then I can learn about what stuck pipe is!". He looked up and peered at me through his safety glasses, and gave me the most disgusted grunt. "You are here to learn, right? Then by all means, learn. Get your PPE, I'll show you what a stuck pipe is. I want you to figure out how to get free, and until you let me know how you are able to do that, or we free the pipe, you will spend your shifts on the rig floor. You will only come down for meals and safety meetings. Is that clear, whoever you say you are?".
Side note: Just for the benefit of non-drillers, during drilling operations, a pipe often with expensive bottom hole assembly (tools, or referred to as BHA) is considered stuck if it cannot be freed from the hole without damaging the pipe, and without exceeding the drilling rig’s maximum allowed hook load.
So there I was, first week offshore, already incurring the wrath of the company man, and already bought a front row seat on a stuck pipe event. The experience itself, is as interesting as the namesake, a pipe stuck, stationery and unmoving. Most days were spent with me spewing obvious solutions like "pull harder...let's try twisting it...let's pull now because maybe whatever has the pipe in its jaws has tired of holding on to it.." As time passed to days, and into the second week, I saw the mighty top drive pull and jar up and down on the pipe in futility, and over time people started to talk to it, hug it, curse at it, but most of the time stare at it. Somebody actually suggested that we slaughter a black chicken and drip the chicken's blood on to the stick up, but when I took the idea seriously and suggested it to town, I could still recall the cruel laughter on the other line and comments about how the contracting to buy the animal alone would take too long. What i learned though was, once a pipe is stuck, it generally stays stuck. The only recovery was to continue to work on the pipe until we received approval to cut the pipe as deep as we can, and pump cement across the tools downhole and leave it buried. As we had nuclear sources in the tools, it was only until the government gave the approval on the 10th day, could the attempts to free the pipe cease, and I saw wireline tools run to cut the pipe, and the recalcitrant pipe finally was freed without the tools downhole, and cement plugs pumped above the abandoned BHA, tools worth millions of dollars left for the next generation to unearth.
Pictured: A picture I found online on how other crews help start the well process with prayers or Pooja. I hope that the flowers and belief did help this particular rig stay trouble free.
If there is anything that the oil fields ingrain into a man, it's humility. We can try to predict what will occur, be ready with an assortment of fallback plans and equipment, and try to avoid certain conditions that might lead to catastrophe. Unfortunately in drilling, we deal with the unknown. The mystery of the unknown is more prominent in exploration or appraisal drilling, but even in development mode, the formation drilled can throw us a curve ball. Every single meter drilled have different characteristics, but challenges for every single meter cannot be addressed with real time changes, at least not with the technology available now. Apart from managed pressure drilling technology, all wells are drilled with normalised planned parameters, tools, fluids and practices, and the mode is always progressing while avoiding catastrophe. But when stuck pipe occurs, while we can likely deduce that its most likely caused by a deviation, a practice that went wrong, we cannot expel the notion that there is the element of the unknown that the sentences the pipe to its final grave.
For non-drillers, I often explain a stuck pipe as an earthquake catching our tools. Indeed the simplified metaphor covers the likely causes of stuck pipe. Formation movement, debris, collapse, ruptures, key seats, pressure differentials are what the common man associates earthquakes with, albeit on a much larger scale. Unfortunately, more often than not, a stuck pipe is notched to a mistake made by the drilling crew. But drilling crews are also human. Training, drills, procedures, data analytics and supervision are all available for the driller and crew to make decisions, but just like our normalised parameters, they are often unable to predict and react easily for every single meter drilled. Thus a stuck pipe event will still remain a real catastrophic event, that until our technology catches up with real time response of equipment with real time inflow of data, we will have to put our faith on the team with the right attitude and knowledge to keep us out of trouble.
However, a stuck pipe event still remains a commercial event. While it does introduce its safety risks with possible flow inside the pipe due to trapped pressure, there are many other drilling incidents that are far worse, often involving immediate injuries, explosive events and death. While any stuck pipe event often brings me back to the memories of my youth, standing across an unmoving stub, full of despair, I would take a hundred stuck pipe events before I would go through the ordeal of having casualties under my watch. Our focus on performance and continued diligence in trouble shooting should never falter, and make we have less stuck pipes in our careers, but more importantly we all stay safe and return to our homes unhurt.

Anthony Rizzo Players Can't Sit On Bench According to a report from the Chicago Sun-Times, the world-famous Anthony Rizzo Phrase "Zombie Rizzo" has been told to never be used again. Of course, this is not the first time that the Zombified Chicago Cubs' first baseman has made headlines this year. A year ago, "Rosebud" was the catchphrase that he coined for himself. Also, there is Anthony Rizzo Shirts that come in his name. Now that the Cubs are World Series Champions, Anthony Rizzo is on his way to superstardom. He is leading the World Series in several categories, including hits, runs, home runs, RBI's, OBP, and SLG. Also, he's on track for a staggering year in hits, RBI's, and total bases, all while being second in home runs.
The Cubs Phenom
This season the Chicago Cubs are over 3.5 million in earnings from the local broadcasts alone. The Cubs could lose a good deal of local revenue if they fail to get back to the World Series. But the local revenue is not the biggest factor in the Cub's success. A large part of their success comes from two of their most popular players, third baseman Kris Bryant and first baseman Anthony Rizzo. These two players are now the favorites to win the MVP awards this year, especially if the Cubs are able to stay on top of the wild card standings. A Look at Rizzo Anthony Rizzo is often compared to his college teammate Andrew McCutchen. Both players have performed well at the plate.
The wood pellet mill, that goes by the name of a wood pellet machine, or wood pellet press, is popular in lots of countries around the world. With all the expansion of "biomass energy", there are now various production technologies utilized to convert biomass into useable electricity and heat. The wood pellet machines are one of the typical machines that complete this task.
Wood pellet mills turn raw materials such as sawdust, straw, or wood into highly efficient biomass fuel. Concurrently, the entire process of converting these materials in a more dense energy form facilitates storage, transport, and make use of on the remainder of any value chain. Later on, you will find plans for biomass fuel to replace traditional fuels. Moreover, wood pellet machines supply the chances to start many different types of businesses.
What Is A Wood Pellet Mill?
Wood pellet machines are kinds of pellet machines to process raw materials including peanut shells, sawdust, leaves, straw, wood, plus more. Today the pellet mills can be purchased in different types. Both the main types include the ring die pellet mills as well as the flat die pellet mills. Wood pellet mills are designed for processing many different types of raw materials irrespective of size. The pellet size is very simple to customize with the use of a hammer mill.
The Benefits Of A Wood Pellet Mill
- The gearboxes are made of high-quality cast iron materials which provide excellent shock absorption and low noise. The wood pellet mills adopt a gear drive that makes a better efficiency in comparison with worm drive or belt drive. The gear drive setup really helps to prevent belt slippage while extending the lifespan in the belt drive.
- The equipment shell includes reinforced ribs and increased casting thickness, which significantly enhances the overall strength of those mills, preventing the breakage in the shell.
- The rollers and die are made of premium-quality alloy steel with 55-60HRC hardness.
- These mills adopt an appropriate wood-processing die-hole structure and die-hole compression ratio.
- The electric-control product is completely compliant with CE standard-os.
- The Emergency Stop button quickly shuts along the mill if you are up against an unexpected emergency.
How To Maintain A Wood Pellet Mill
- The belt tightness ought to be checked regularly. If it is now slack, it needs to be tightened immediately.
- The equipment should be situated in a nicely-ventilated area to ensure the temperature created by the motor can emit safely, to extend the lifespan of your machine.
- Before restarting the appliance, any remaining debris has to be cleared from the machine room to reduce starting resistance.
- Oil must be filled regularly to every bearing to market inter-lubricating.
- To ensure the cutter remains sharp, check this part regularly to prevent unnecessary damages for any other part.
- Regularly inspect the cutter screws, to make sure the bond involving the knife and blade remains strong.
- The machine should take a seat on an excellent foundation. Regular maintenance of your machine will prolong the complete lifespan of the machinery.
It was shaping up to yet another dull OPEC+ meeting. Cut and dry. Copy and paste. Rubber-stamping yet another monthly increase in production quotas by 432,000 b/d. Month after month of resisting pressure from the largest economies in the world to accelerate supply easing had inured markets to expectations of swift action by OPEC and its wider brethren in OPEC+.
And then, just two days before the meeting, chatter began that suggested something big was brewing. Whispers that Russia could be suspended made the rounds, an about-face for a group that has steadfastly avoided reference to the war in Ukraine, calling it a matter of politics not markets. If Russia was indeed removed from the production quotas, that would allow other OPEC+ producers to fill in the gap in volumes constrained internationally due to sanctions.
That didn’t happen. In fact, OPEC+ Joint Technical Committee commented that suspension of Russia’s quota was not discussed at all and not on the table. Instead, the JTC reduced its global oil demand forecast for 2022 by 200,000 b/d, expecting global oil demand to grow by 3.4 mmb/d this year instead with the downside being volatility linked to ‘geopolitical situations and Covid developments.’ Ordinarily, that would be a sign for OPEC+ to hold to its usual supply easing schedule. After all, the group has been claiming that oil markets have ‘been in balance’ for much of the first five months of 2022. Instead, the group surprised traders by announcing an increase in its monthly oil supply hike for July and August, adding 648,000 b/d each month for a 50% rise from the previous baseline.
The increase will be divided proportionally across OPEC+, as has been since the landmark supply deal in spring 2020. Crucially this includes Russia, where the new quota will be a paper one, since Western sanctions means that any additional Russian crude is unlikely to make it to the market. And that too goes for other members that haven’t even met their previous lower quotas, including Iraq, Angola and Nigeria. The oil ministers know this and the market knows this. Which is why the surprise announcement didn’t budge crude prices by very much at all.
In fact, there are only two countries within OPEC+ that have enough spare capacity to be ramped up quickly. The United Arab Emirates, which was responsible for recent turmoil within the group by arguing for higher quotas should be happy. But it will be a measure of backtracking for the only other country in that position, Saudi Arabia. After publicly stating that it had ‘done all it can for the oil market’ and blaming a lack of refining capacity for high fuel prices, the Kingdom’s change of heart seems to be linked to some external pressure. But it could seemingly resist no more. But that spotlight on the UAE and Saudi Arabia will allow both to wrench some market share, as both countries have been long preparing to increase their production. Abu Dhabi recently made three sizable onshore oil discoveries at Bu Hasa, Onshore Block 3 and the Al Dhafra Petroleum Concession, that adds some 650 million barrels to its reserves, which would help lift the ceiling for oil production from 4 to 5 mmb/d by 2030. Meanwhile, Saudi Aramco is expected to contract over 30 offshore rigs in 2022 alone, targeting the Marjan and Zuluf fields to increase production from 12 to 13 mmb/d by 2027.
The UAE wants to ramp up, certainly. But does Saudi Arabia too? As the dominant power of OPEC, what Saudi Arabia wants it usually gets. The signals all along were that the Kingdom wanted to remain prudent. It is not that it cannot, there is about a million barrels per day of extra production capacity that Saudi Arabia can open up immediately but that it does not want to. Bringing those extra volume on means that spare capacity drops down to critical levels, eliminating options if extra crises emerge. One is already starting up again in Libya, where internal political discord for years has led to an on-off, stop-start rhythm in Libyan crude. If Saudi Arabia uses up all its spare capacity, oil prices could jump even higher if new emergencies emerge with no avenue to tackle them. That the Saudis have given in (slightly) must mean that political pressure is heating up. That the announcement was made at the OPEC+ meeting and not a summit between US and Saudi leaders must mean that a façade of independence must be maintained around the crucial decisions to raise supply quotas.
But that increase is not going to be enough, especially with Russia’s absence. Markets largely shrugged off the announcement, keeping Brent crude at US$120/b levels. Consumption is booming, as the world rushes to enjoy its first summer with a high degree of freedom since Covid-19 hit. Which is why global leaders are looking at other ways to tackle high energy prices and mitigate soaring inflation. In Germany, low-priced monthly public transport are intended to wean drivers off cars. In the UK, a windfall tax on energy companies should yield US$6 billion to be used for insulating consumers. And in the US, Joe Biden has been busy.
With the Permian Basin focusing on fiscal prudence instead of wanton drilling, US shale output has not responded to lucrative oil prices that way it used to. American rig counts are only inching up, with some shale basins even losing rigs. So the White House is trying more creative ways. Though the suggestion of an ‘oil consumer cartel’ as an analogue to OPEC by Italian Prime Minister Mario Draghi is likely dead on arrival, the US is looking to unlock supply and tame fuel prices through other ways. Regular releases from the US Strategic Petroleum Reserve has so far done little to bring prices down, but easing sanctions on Venezuelan crude that could be exported to the US and Europe, as well as working with the refining industry to restart recently idled refineries could. Inflation levels above 8% and gasoline prices at all-time highs could lead to a bloody outcome in this year’s midterm elections, and Joe Biden knows that.
But oil (and natural gas) supply/demand dynamics cannot truly start returning to normal as long as the war in Ukraine rages on. And the far-ranging sanctions impacting Russian energy exports will take even longer to be lifted depending on how the war goes. Yes, some Russian crude is making it to the market. China, for example, has been quietly refilling its petroleum reserves with Russian crude (at a discount, of course). India continues to buy from Moscow, as are smaller nations like Sri Lanka where an economic crisis limits options. Selling the crude is one thing, transporting it is another. With most international insurers blacklisting Russian shippers, Russian oil producers can still turn to local insurance and tankers from the once-derided state tanker firm Sovcomflot PJSC to deliver crude to the few customers they still have.
A 50% hike in OPEC’s monthly supply easing targets might seem like a lot. But it isn’t enough. Especially since actual production will fall short of that quota. The entire OPEC system, and the illusion of control it provides has broken down. Russian oil is still trickling out to global buyers but even if it returned in full, there is still not enough refining capacity to absorb those volumes. Doctors speak of long Covid symptoms in patients, and the world energy complex is experiencing long Covid, now with a touch with geopolitical germs as well. It’ll take a long time to recover, so brace yourselves.
