Drilling & Completions

I used to be a pure red blooded driller. Red, the colour of fire and blood, associated with energy, war, danger, strength, power, determination as well as passion, desire, and love. And all of that hot emotions was for my passion to drill. I did not care about anything else other than well length, cost, time, and how great I was at selecting the right tool, using it and of course telling people about my accomplishments. And in Feb 2004, I reached the very pinnacle of being a drilling engineer. I drilled, single handedly (that shall go in my future memoirs), the longest well in Malaysia. At 6313mMD, I, the lead drilling engineer, held the Malaysian record for longest well ever drilled.


Unfortunately that intense self admiration and jubilation was short lived, when in a few weeks that record was broken by another operator. My ego deflated, my self worth diminishing by every mention of the other well's length, I banged my forehead whenever I thought of them who beat my record by a measly 50m. And of course, being a red blooded driller, the only lesson I learned was to just to drill longer next time. If I ever drilled another record breaking well, I will make sure I just put in some contingency shale drilling of about ~60m, so that I never get beaten again -_-

Sadly, I have never had a chance again, because since 2004, there have only been a handful of ultra ERD wells drilled. To put this into perspective, the longest well currently in Malaysia was drilled in 2014 to ~6700m, which is a laudable achievement, but exemplifies a slow progression over 10 years. As a driller, I feel that it is my responsibility to revive the interest in ERD and invigorate the passion for world class records which has since waned in the Malay Basin.


But now I've since gone to the Dark Side (Star Wars trademark), the side that bleeds hydrocarbon, I realise that my previous infatuation with drilling KPIs just seems so irrelevant in the grand scheme of things, when the oil business bottom line are production and profits, and doesn't really give a hoot on how long a well is. To stay profitable, and as reserves become even smaller and difficult to access, it has becomes an ever-more important to focus on looking at several concepts with enabling techniques, to be able to select the right solution to exploit hydrocarbons. As a driller, nothing is sexier and more elegant than suggesting extended reach drilling. While its the most straightforward option which allows the ability to explore and produce further and deeper, and minimise facilities installation, it does come with added risk and possibility of failure.


Any solution proposed requires capital expenditure. And capital expenditure proposals must be sufficiently specific to permit their technical and commercial justification, with sufficient risk assessment, for exploration and production operations, not just for the immediate fiscal year, but the life of the production sharing contract or field. In the economic phase of evaluation, oil management may find that it has more investment opportunities than capital to invest, or more capital to invest than investment opportunities. Whichever situation exists, oil management needs to resort to some economic criteria for selecting or rejecting investment proposals. Management’s decision in either case is likely to be based largely on the measures of financial return on the investment. In the current depressed oil price climate, how do we make extended reach drilling a viable option?


I won’t pretend that I’m an expert at economics like Wally in the Dilbert strip above, but let’s try to simplify the concept for the purpose of this article. Lets just say, all of the KPIs of a well, production, cost, schedule, IRR, ROI, terms of PSC, can all be rolled into a variable limit, the economic threshold of the project.


This chart represents the likelihood of costs in a normal Monte Carlo S-curve spread, where the cost of a project is typically quoted as the P50, with a range given for sensitivities. In layman's terms, the mid case is the P50 (50% chance having costs below that threshold) and P10 and P90 is the low and high side respectively. The range of costs are given so that the project can be carefully evaluated against the returns for any given scenario.


However, most projects focus on the most straightforward approach, which is trying to reduce base cost ('What we plan for' curve), in an attempt to get closer to the low side, and hope that nothing goes wrong to upset the cart and skew to the upside. To shift the whole S-curve downwards, the team will negotiate contracts, purchase cheaper tangibles/consumables, reduce the technology, and try to get the work done with a lean operation. However, as we lower down our price point, we will inevitably be introducing creep, compromising quality and safety. Post experiencing a trainwreck, the looming result is cost inadvertently passing the economic threshold ('What will actually happen' curve).

A prudent project manager should try to visualise, manage and contain all of the outcomes, trying to put a cap on the risk and exposure of the upside, while making the likelihood of meeting the P50 expectation more likely, even if it means increasing the mid-case, and forgoing a more aggressive P10 ('What we actually need' Green curve). To put it simply, don't lose the farm while trying to save every single dollar.

If you are planning to justify a new technology, a new technique, or a risky proposition such as extended reach drilling, there are 5 key elements that you need in your proposal, to emulate the 'What we actually need' green curve:


Key 1: Collaborate and Build the knowledge of your team: Collaborate as much as possible internally, and externally with partners, host government, increase data trade transactions, and engage professional networks in order to learn as much as you can on the venture you are undertaking. In this environment, you will be pleasantly surprised that others might actually be interested to learn from you to. In my previous life, I was part of an assurance team, called upon by our partner in Western Australia to look at their concept work. They were down to two options, where they were weighing a 10km ERD well versus a subsea development, where the costs of subsea were 50% higher. The upside costs presented by the drilling team for the ERD looked reasonable, with their P90 costs about a wash with the subsea well. So on paper, ERD looked to be the right selection. However, the Drilling Manager confessed that despite the economics and his attempt to show the risks, he believes that his team does not have the capability to carry out the work, in other words the drillability due to the capability was questionable. The ERD well was dropped in favor of the subsea well, and everybody agreed that was the right call, because regardless what the evaluation on paper shows, there was no confidence in the team that was to carry the work out. Pity.


Key 2: Cap your upside costs: Gone are the days when people say, "A well is going to cost what its going to cost". Have savvier contracts, such as with lump sum capped, performance incentivised, meterage measured or even turnkeyed contract. We should no longer be dependent on time based contracts, just because the supplier says so. Determine the cost structure which fits your project and design your contracts to meet what is required


Key 3: Increase your execution reliability: This doesn't mean not having problems. What it means is being able to deliver what you promised. So if the design is complex, and on average non productive time is high, design the lower complexity aspects of the project to absorb the possible problems that you will eventually have. Sometimes you have to accept that your planned costs would have to be higher to increase reliability. Justify the increase and plan for success, but be ready for failure.


Key 4: Have contingency plans for everything, even failure of your base plan: It goes without saying that risk assessments are the support system for a project, but without closing out and implementing any of the mitigation plans, the risk assessment are just a waste of time. An always think of what would happen if the primary plan fails? Do you have a fall back plan to still retain value or limit exposure? An alternative target, perhaps? A ready for deployment sidetrack assembly?


Key 5: Increase the value statement of your design: During detailed design, a D&C team often gets carried away on focusing too much on 'getting the job' done versus remembering why the job was done in the first place. Reaching an objective is just the means to extract the value from the project. Design the well in order to increase the returns on the project, and increase the economic threshold. Drill better wells, which doesn't necessarily mean drilling longer or more wells.

Hopefully the keys above will assist the reader in creating more palatable ERD proposals. Every single project, every single team, and every single company will have a different approach in creating value, but I do hope that maybe in some minute way, I managed to jog some life back into excitement about drilling and ERD in Malaysia. Stay savvy, people.

Average U.S. construction costs for solar and wind generation continue to fall

According to 2018 data from the U.S. Energy Information Administration (EIA) for newly constructed utility-scale electric generators in the United States, annual capacity-weighted average construction costs for solar photovoltaic systems and onshore wind turbines have continued to decrease. Natural gas generator costs also decreased slightly in 2018.

From 2013 to 2018, costs for solar fell 50%, costs for wind fell 27%, and costs for natural gas fell 13%. Together, these three generation technologies accounted for more than 98% of total capacity added to the electricity grid in the United States in 2018. Investment in U.S. electric-generating capacity in 2018 increased by 9.3% from 2017, driven by natural gas capacity additions.

The average construction cost for solar photovoltaic generators is higher than wind and natural gas generators on a dollar-per-kilowatt basis, although the gap is narrowing as the cost of solar falls rapidly. From 2017 to 2018, the average construction cost of solar in the United States fell 21% to $1,848 per kilowatt (kW). The decrease was driven by falling costs for crystalline silicon fixed-tilt panels, which were at their lowest average construction cost of $1,767 per kW in 2018.

Crystalline silicon fixed-tilt panels—which accounted for more than one-third of the solar capacity added in the United States in 2018, at 1.7 gigawatts (GW)—had the second-highest share of solar capacity additions by technology. Crystalline silicon axis-based tracking panels had the highest share, with 2.0 GW (41% of total solar capacity additions) of added generating capacity at an average cost of $1,834 per kW.

Total U.S. wind capacity additions increased 18% from 2017 to 2018 as the average construction cost for wind turbines dropped 16% to $1,382 per kW. All wind farm size classes had lower average construction costs in 2018. The largest decreases were at wind farms with 1 megawatt (MW) to 25 MW of capacity; construction costs at these farms decreased by 22.6% to $1,790 per kW.

Natural gas
Compared with other generation technologies, natural gas technologies received the highest U.S. investment in 2018, accounting for 46% of total capacity additions for all energy sources. Growth in natural gas electric-generating capacity was led by significant additions in new capacity from combined-cycle facilities, which almost doubled the previous year’s additions for that technology. Combined-cycle technology construction costs dropped by 4% in 2018 to $858 per kW.

Fossil fuels account for the largest share of U.S. energy production and consumption

Fossil fuels, or energy sources formed in the Earth’s crust from decayed organic material, including petroleum, natural gas, and coal, continue to account for the largest share of energy production and consumption in the United States. In 2019, 80% of domestic energy production was from fossil fuels, and 80% of domestic energy consumption originated from fossil fuels.

The U.S. Energy Information Administration (EIA) publishes the U.S. total energy flow diagram to visualize U.S. energy from primary energy supply (production and imports) to disposition (consumption, exports, and net stock additions). In this diagram, losses that take place when primary energy sources are converted into electricity are allocated proportionally to the end-use sectors. The result is a visualization that associates the primary energy consumed to generate electricity with the end-use sectors of the retail electricity sales customers, even though the amount of electric energy end users directly consumed was significantly less.

The share of U.S. total energy production from fossil fuels peaked in 1966 at 93%. Total fossil fuel production has continued to rise, but production has also risen for non-fossil fuel sources such as nuclear power and renewables. As a result, fossil fuels have accounted for about 80% of U.S. energy production in the past decade.

Since 2008, U.S. production of crude oil, dry natural gas, and natural gas plant liquids (NGPL) has increased by 15 quadrillion British thermal units (quads), 14 quads, and 4 quads, respectively. These increases have more than offset decreasing coal production, which has fallen 10 quads since its peak in 2008.

In 2019, U.S. energy production exceeded energy consumption for the first time since 1957, and U.S. energy exports exceeded energy imports for the first time since 1952. U.S. energy net imports as a share of consumption peaked in 2005 at 30%. Although energy net imports fell below zero in 2019, many regions of the United States still import significant amounts of energy.

Most U.S. energy trade is from petroleum (crude oil and petroleum products), which accounted for 69% of energy exports and 86% of energy imports in 2019. Much of the imported crude oil is processed by U.S. refineries and is then exported as petroleum products. Petroleum products accounted for 42% of total U.S. energy exports in 2019.

The share of U.S. total energy consumption that originated from fossil fuels has fallen from its peak of 94% in 1966 to 80% in 2019. The total amount of fossil fuels consumed in the United States has also fallen from its peak of 86 quads in 2007. Since then, coal consumption has decreased by 11 quads. In 2019, renewable energy consumption in the United States surpassed coal consumption for the first time. The decrease in coal consumption, along with a 3-quad decrease in petroleum consumption, more than offset an 8-quad increase in natural gas consumption.

EIA previously published articles explaining the energy flows of petroleum, natural gas, coal, and electricity. More information about total energy consumption, production, trade, and emissions is available in EIA’s Monthly Energy Review.

Nord Stream 2: Democratic Ideals or Business Reality

It was an innocuous set of words published in a newspaper in Germany on Sunday. “I hope the Russian do not force us to change our position on Nord Stream 2”, the German Foreign Minister Heiko Maas was quoted as saying. A day after that, Angela Merkel also issued a single sentence: “The German Chancellor agrees with the Foreign Minister’s comments from the weekend.” Simple words with a bold message. And potentially devastating consequences.

The incident that hardened the hearts of Germany , which had become increasingly isolated over the issue of the Nord Stream 2 natural gas pipeline that connects Russia to Germany through the Baltic Sea, was the hospitalisation of Russian opposition leader Alexei Navalny. Airlifted to Berlin following a medically-induced coma, German doctors concluded that Navalny, who is no stranger to intimidation tactics by the Putin government, was the victim of the Novichok nerve agent. If that name sounds familiar, that’s because it made headlines in 2018 over the attempted assassination of former Russian spy Sergei Skripal and his daughter Yulia in Salisbury, UK. A lethal nerve agent developed in the 1970s in Soviet Russia, Novichok is among the deadliest poisons ever developed and is banned under the Organisation for the Prohibition of Chemical Weapons. The Kremlin, predictably, denies involvement in the alleged poisoning, dismissing the German allegations as untrue.

That this could be the straw that broke the Nord Stream 2 back is perhaps surprising. The Nord Stream 2 natural gas pipeline has survived many obstacles. Many, many obstacles. The sequel to the original 1,222km Nord Stream that was inaugurated in November 2011, Nord Stream 2 will add 1,230km more pipeline between Vyborg in Russia and Lubin in Germany, with nearly all of the entire 2,452km length already being laid. Championed by former German Chancellor Gerhard Schröder and inherited by Merkel, the Nord Stream pipelines were developed to meet Germany’s growing energy demand, as it moved away from burning coal and nuclear fission. However, it has attracted criticism from many quarters. From Germany’s neighbours including Poland, Denmark and Estonia concerned over the pipeline that passes through their waters. From the EU, concerned about making Germany too energy dependent from a ‘politically unreliable’ country. From the US, which has threatened and, indeed, imposed sanctions on companies involved in the project. Some would argue that the vociferous US involvement, championed by President Donald Trump is self-serving, meant to allow US energy exports to muscle in, but it still fits neatly into Germany’s Russian dependence issue.

Throughout all this drama, Angela Merkel has stood firm. She, and her centre-right party CDU, have supported Nord Stream somewhat unenthusiastically with the primary concerns being the business element. It will unravel Germany’s plans to become a natural gas hub, as it tries to drive an EU movement towards cleaner energy. Many of Germany’s largest companies,  include petrochemicals giant BASF and its energy arm Wintershall are also heavily invested in Nord Stream and the raw gas it will bring. It would also be a reputational risk to pull the plug on a project that is almost complete and set to be launched by the year’s end, and still leaves the critical question on how Germany will be able to address its energy deficit.

The business argument has overridden political concerns so far. But now a moral imperative has arisen through the attempted murder of Alexei Navalny, with his subsequent medical treatment in Berlin. This resonates in Germany particularly, since the country understands the historical consequences of authoritarian governments and the dangers it bring. The shifting of the political landscape, especially the rise of the Green Party has triggered a ferocious debate with high-ranking politicians from both the left and right calling for the project to be scrapped. Some are even arguing that Nord Stream 2 gas supply is no longer necessary, as the country’s energy requirements are now fundamentally shifting in a post-Covid 19 world.

If, and that is a very big if, the Nord Stream 2 is scrapped, that is at least US$9.4 billion down the drain and plenty more in collateral damage from peripheral activities. It will rock the boat when the usual Merkel instinct is to steady it. But the furore over an attempted assassination by one of the world’s deadliest methods no less, might be a stand that Germany is willing to take. After all, it knows first-hand the effects of an iron fist. Berlin has so far stood alone in advancing Nord Stream 2, even after the chorus of critics surrounding it grow louder and louder. If it were to kill the project, Germany could find plenty of supporters for that move and would be more than happy to offer themselves up as a role to scupper this ship. The options are varied, but one question remains that will influence the whole issue: how is Angela Merkel willing to go to take a stand over democratic ideals or business reality?

Market Outlook:

  • Crude price trading range: Brent – US$39-41/b, WTI – US$36-38/b
  • A second global acceleration in Covid-19 cases is hampering hopes that the worldwide economy will be able to return to normality by the year’s end, delaying the time it will take for crude demand to return to its pre-crisis level
  • With the summer driving season in the northern hemisphere coming to a close, US crude stockpiles are rising, driving down prices even though the US EIA raised its forecasts for 2020 to US$38.99 for WTI and US$41.90 for Brent
  • The downturn in prices was also driven by Saudi Arabia cutting its crude pricing for October sales by a larger-than-expected amount, especially for Asian shipments
