Drilling & Completions

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.

Leveraging Synergies Created by the Convergence of Operational and Engineering Technologies and Digitalisation, Can Deliver Significant Savings for Energy Companies

Pioneering technology expert tells ADIPEC Energy Dialogue up to 80 per cent of plant shutdowns could be mitigated through combination of advanced electrification, automation and digitalisation technologies


Greater use of renewables in power management processes offers oil and gas companies opportunities to create efficiencies, sustainability and affordability when modernising equipment, or planning new CAPEX projects

Abu Dhabi, UAE – XX August 2020 – Leveraging the synergies created by the convergence of electrification, automation and digitalisation, can create significant cost savings for oil and gas companies when making both operational and capital investment decisions, according to Dr Peter Terwiesch, President of Industrial Automation at ABB, a Swiss-Swedish multinational company, operating mainly in robotics, power, heavy electrical equipment, and automation technology areas.

Participating in the latest ADIPEC Energy Dialogue, Dr Terwiesch said up to 80 per cent of energy industry plant shutdowns, caused by human error, or rotating machinery or power outages, could be mitigated through a combination of electrification, automation and digitalisation.

“Savings are clearly possible not only on the operation side but also, using the same synergies between dimensions, you can bring down the cost schedule and risk of capital investment, especially in a time when making projects work economically is harder,” explained Dr Terwiesch.

A pioneering technology leader, who works closely with utility, industry, transportation and infrastructure customers, Dr Terwiesch said despite the increasing investment by oil and gas companies in renewables and the growing use of renewables to generate electricity, both for individual and industrial uses, hydrocarbons will continue to have an important role in creating energy, in the short to medium term.

“If you look at the energy density constraints, clearly electricity is gaining share but electricity is not the source of energy; it is a conduit of energy. The energy has to come from somewhere and that can be hydrocarbons, or nuclear, or renewables.” he said.

Nevertheless, he added, the greater use of renewables to generate electricity offers oil and gas companies the option of integrating a higher share of renewables into power management processes to create efficiencies, sustainability and affordability when modernising equipment, or planning new CAPEX projects.

The ADIPEC Energy Dialogue is a series of online thought leadership events created by dmg events, organisers of the annual Abu Dhabi International Exhibition and Conference. Featuring key stakeholders and decision-makers in the oil and gas industry, the dialogues focus on how the industry is evolving and transforming in response to the rapidly changing energy market.

With this year’s in person ADIPEC exhibition and conference postponed to November 2021, the ADIPEC Energy Dialogue, along with insightful webinars, podcasts and on line panels continue to connect the oil and gas industry, with the challenges and opportunities shaping energy markets in the run up to, and following, a planned three-day live stream virtual ADIPEC conference taking place from November 9-11.

An industry first of its kind, the online conference will bring together energy leaders, ministers and global oil and gas CEOs to assess the collective measures the industry needs to put in place to fast-track recovery, post COVID-19.

Forecast Highlights

  • The August Short-Term Energy Outlook (STEO) remains subject to heightened levels of uncertainty because mitigation and reopening efforts related to the 2019 novel coronavirus disease (COVID-19) continue to evolve. Reduced economic activity related to the COVID-19 pandemic has caused changes in energy demand and supply patterns in 2020. Uncertainties persist across the U.S. Energy Information Administration’s (EIA) outlook for all energy sources, including liquid fuels, natural gas, electricity, coal, and renewables. The STEO is based on U.S. macroeconomic forecasts by IHS Markit, which assume U.S. gross domestic product declined by 5.2% in the first half of 2020 from the same period a year ago and will rise from the third quarter of 2020 through 2021.
  • Daily Brent crude oil spot prices averaged $43 per barrel (b) in July, up $3/b from the average in June and up $25/b from the multiyear low monthly average price in April. EIA expects monthly Brent spot prices will average $43/b during the second half of 2020 and rise to an average of $50/b in 2021.
  • U.S. regular gasoline retail prices averaged $2.18 per gallon (gal) in July, an increase of 10 cents/gal from the average in June but 56 cents/gal lower than at the same time last year. EIA expects that gasoline prices will gradually decrease through the rest of the summer to reach an average of $2.04/gal in September before falling to an average of $1.99/gal in the fourth quarter. Forecast U.S. regular gasoline retail prices will average $2.23/gal in 2021, compared with an average of $2.12/gal in 2020.
  • EIA expects high inventory levels and surplus crude oil production capacity will limit upward price pressures in the coming months, but as inventories decline into 2021, those upward price pressures will increase. EIA estimates global liquid fuels inventories rose at a rate of 6.4 million barrels per day (b/d) in the first half of 2020 and expects they will decline at a rate of 4.2 million b/d in the second half of 2020 and then decline by 0.8 million b/d in 2021.
  • EIA estimates that demand for global petroleum and liquid fuels averaged 93.4 million b/d in July. Demand was down 9.1 million b/d from July 2019, but it was up from an average of 85.0 million b/d during the second quarter of 2020, which was down 15.8 million b/d from year-ago levels. EIA forecasts that consumption of petroleum and liquid fuels globally will average 93.1 million b/d for all of 2020, down 8.1 million b/d from 2019, before increasing by 7.0 million b/d in 2021. Reduced economic activity related to the COVID-19 pandemic has caused changes in energy supply and demand patterns in 2020.
  • EIA estimates that global liquid fuels production averaged 91.8 million b/d in the second quarter of 2020, down 8.6 million b/d year over year. The decline reflects voluntary production cuts by the Organization of the Petroleum Exporting Countries (OPEC) and partner countries (OPEC+), and reductions in drilling activity and production curtailments in the United States because of low oil prices. In the forecast, the global supply of oil continues to decline to 90.4 million b/d in the third quarter of 2020 before rising to an annual average of 99.4 million b/d in 2021.
  • EIA estimates that U.S. liquid fuels consumption averaged 16.2 million b/d in the second quarter of 2020, down 4.1 million b/d (20%) from the same period in 2019. The decline reflects travel restrictions and reduced economic activity related to COVID-19 mitigation efforts. EIA expects U.S. oil consumption will generally rise through the end of 2021. EIA forecasts U.S. liquid fuels consumption will average 18.9 million b/d in the third quarter of 2020 (down 1.8 million b/d year over year) before rising to an average of 20.0 million b/d in 2021. Although the 2021 forecast level is 1.6 million b/d more than EIA’s forecast 2020 consumption, it is 0.4 million b/d less than the 2019 average.
  • EIA has lowered U.S. crude oil production estimates for 2020 by 370,000 b/d from the previous STEO. EIA expects crude production to average 11.3 million b/d in 2020 and 11.1 million b/d in 2021, down from 12.2 million b/d in 2019. Recently released EIA data show that average monthly U.S. oil production for May was 1.2 million b/d lower than the July STEO forecast, indicating more extensive production curtailments than previously estimated. Also, EIA’s August STEO assumes that the Dakota Access Pipeline will remain operational. A U.S. District Court ordered on July 6 the temporary closure of the Dakota Access Pipeline beginning in early August. A U.S. appeals court has overturned the lower court decision, allowing the pipeline to remain running while further litigation proceedings continue.
  • In July, the Henry Hub natural gas spot price averaged $1.77 per million British thermal units (MMBtu). EIA expects natural gas prices will generally rise through the end of 2021 but the sharpest increases will be during this fall and winter when they rise from an average of $2.11/MMBtu in September to $3.14/MMBtu in February. EIA expects that rising demand heading into winter, combined with reduced production, will cause upward price pressures. EIA forecasts that Henry Hub natural gas spot prices will average $2.03/MMBtu in 2020 and $3.14/MMBtu in 2021.
  • EIA estimates that total U.S. working natural gas in storage ended July at about 3.3 trillion cubic feet (Tcf), 15% more than the five-year (2015–19) average. In the forecast, inventories rise by 2.0 Tcf during the April-through-October injection season to reach nearly 4.0 Tcf on October 31.
  • EIA expects that total U.S. consumption of natural gas will average 82.4 billion cubic feet per day (Bcf/d) in 2020, down 3.0% from 2019. The largest decline in consumption occurs in the industrial sector, which EIA forecasts will average 22.0 Bcf/d in 2020, down 1.0 Bcf/d from 2019, as a result of reduced manufacturing activity. The decline in total U.S. consumption also reflects lower heating demand in early 2020, contributing to residential and commercial demand in 2020 averaging 12.8 Bcf/d (down 0.9 Bcf/d from 2019) and 8.8 Bcf/d (down 0.8 Bcf/d from 2019), respectively.
  • U.S. dry natural gas production set an annual record in 2019, averaging 92.2 Bcf/d. EIA forecasts dry natural gas production will average 88.7 Bcf/d in 2020, with monthly production falling from its monthly average peak of 96.2 Bcf/d in November 2019 to 82.7 Bcf/d by April 2021, before increasing slightly. Natural gas production declines the most in the Permian region, where EIA expects low crude oil prices will reduce associated natural gas output from oil-directed rigs. EIA’s forecast of dry natural gas production in the United States averages 84.0 Bcf/d in 2021. EIA expects production to begin rising in the second quarter of 2021 in response to higher natural gas and crude oil prices.
  • EIA estimates that U.S. liquefied natural gas (LNG) exports will average 5.5 Bcf/d in 2020 and will average 7.3 Bcf/d in 2021. EIA expects that U.S. LNG exports will decline through the end of the summer as a result of reduced global demand for natural gas. U.S. exports of LNG in July 2020 averaged 3.1 Bcf/d, which is about the same as in May 2018, when the available liquefaction capacity was about one-third of the current capacity. Declines in global natural gas demand associated with COVID-19 mitigation efforts, high natural gas storage inventories in Europe and Asia, and an on-going expansion in LNG liquefaction capacity have contributed to natural gas and LNG prices reaching all-time historical lows. Low international prices have affected the economic competitiveness of U.S. LNG exports and have led to numerous cargo cancellations, particularly at the Sabine Pass, Corpus Christi, and Freeport LNG export terminals. EIA expects LNG exports from the United States to remain low in the next few months. Based on numerous trade press reports, EIA estimates about 45 cargoes have been canceled for upcoming August shipments and about 30 cargoes have been canceled for September shipments.
  • EIA forecasts 3.6% less electricity consumption in the United States in 2020 compared with 2019. The largest decline on a percentage basis is in the commercial sector, where EIA expects retail sales of electricity to fall by 7.4% this year. Forecast industrial retail electricity sales fall by 5.8%. EIA forecasts residential sector retail sales will increase by 2.0% in 2020. Milder winter temperatures earlier in the year led to lower consumption for space heating, but that factor is offset by increased summer cooling demand and an assumed increase in electricity use by more people working from home. In 2021, EIA forecasts total U.S. electricity consumption will rise by 0.8%.
  • EIA expects the share of U.S. electric power sector generation from natural gas-fired power plants will increase from 37% in 2019 to 40% this year. In 2021, the forecast natural gas share declines to 35% in response to higher natural gas prices. Coal’s forecast share of electricity generation falls from 24% in 2019 to 18% in 2020 and then increases to 22% in 2021. Electricity generation from renewable energy sources rises from 17% in 2019 to 20% in 2020 and to 22% in 2021. The increase in the share from renewables is the result of expected additions to wind and solar generating capacity. EIA expects a decline in nuclear generation in both 2020 and 2021, reflecting recent and upcoming retirements of nuclear generating capacity.
  • EIA forecasts that renewable energy will be the fastest-growing source of electricity generation in 2020. EIA expects the electric power sector will add 23.2 gigawatts (GW) of new wind capacity and 12.9 GW of utility-scale solar capacity in 2020. However, these future capacity additions are subject to a high degree of uncertainty, and EIA continues to monitor reported planned capacity builds.
  • U.S. coal consumption, which dropped to its lowest point since April, totaled 95 MMst in the second quarter of 2020. EIA expects coal consumption to rise to a seasonal peak of 127 MMst in the third quarter but remain lower than 2019 levels through the end of 2020. EIA estimates that U.S. coal consumption will decrease by 26% in 2020 and increase by 20% in 2021. EIA estimates that total U.S. coal production in 2020 will decrease by 29% from 2019 levels to 502 MMst. In 2021, EIA expects higher demand and rising natural gas prices to a lead to a recovery in coal production of 12%, with a total annual production level of 564 MMst.
  • EIA forecasts that U.S. energy-related carbon dioxide (CO2) emissions, after decreasing by 2.8% in 2019, will decrease by 11.5% (588 million metric tons) in 2020. This record decline is the result of less energy consumption related to restrictions on business and travel activity and slowing economic growth related to COVID-19 mitigation efforts. CO2 emissions decline with reduced consumption of all fossil fuels, particularly coal (24.9%) and petroleum (11.6%). In 2021, EIA forecasts that energy-related CO2 emissions will increase by 5.6%, as the economy recovers and stay-at-home orders are lifted. Energy-related CO2 emissions are sensitive to changes in weather, economic growth, energy prices, and fuel mix.

Utility-scale battery storage capacity continued its upward trend in 2018

Utility-scale battery storage systems are increasingly being installed in the United States. In 2010, the United States had seven operational battery storage systems, which accounted for 59 megawatts (MW) of power capacity (the maximum amount of power output a battery can provide in any instant) and 21 megawatthours (MWh) of energy capacity (the total amount of energy that can be stored or discharged by a battery). By the end of 2018, the United States had 125 operational battery storage systems, providing a total of 869 MW of installed power capacity and 1,236 MWh of energy capacity.

Battery storage systems store electricity produced by generators or pulled directly from the electrical grid, and they redistribute the power later as needed. These systems have a wide variety of applications, including integrating renewables into the grid, peak shaving, frequency regulation, and providing backup power.

Most utility-scale battery storage capacity is installed in regions covered by independent system operators (ISOs) or regional transmission organizations (RTOs). Historically, most battery systems are in the PJM Interconnection (PJM), which manages the power grid in 13 eastern and Midwestern states as well as the District of Columbia, and in the California Independent System Operator (CAISO). Together, PJM and CAISO accounted for 55% of the total battery storage power capacity built between 2010 and 2018. However, in 2018, more than 58% (130 MW) of new storage power capacity additions, representing 69% (337 MWh) of energy capacity additions, were installed in states outside of those areas.

In 2018, many regions outside of CAISO and PJM began adding greater amounts of battery storage capacity to their power grids, including Alaska and Hawaii, the Electric Reliability Council of Texas (ERCOT), and the Midcontinent Independent System Operator (MISO). Many of the additions were the result of procurement requirements, financial incentives, and long-term planning mechanisms that promote the use of energy storage in the respective states. Alaska and Hawaii, which have isolated power grids, are expanding battery storage capacity to increase grid reliability and reduce dependence on expensive fossil fuel imports.

Note: The cost range represents cost data elements from the 25th to 75th percentiles for each year of reported cost data.

Average costs per unit of energy capacity decreased 61% between 2015 and 2017, dropping from $2,153 per kilowatthour (kWh) to $834 per kWh. The large decrease in cost makes battery storage more economical, helping accelerate capacity growth. Affordable battery storage also plays an important role in the continued integration of storage with intermittent renewable electricity sources such as wind and solar.

Additional information on these topics is available in the U.S. Energy Information Administration’s (EIA) recently updated Battery Storage in the United States: An Update on Market Trends. This report explores trends in battery storage capacity additions and describes the current state of the market, including information on applications, cost, market and policy drivers, and future project developments.
