[ Below is a post by Art Berman which I found interesting because I’m concerned about whether enough diesel can be made in the future to keep trucks running. Light tight “fracked” oil is better at making plastics and gasoline than diesel fuel. Tar sands need natural gas or light oil additions to thin the tarry asphalt enough to get through pipelines to refineries to be further refined with light “fracked” oil, hence the happy marriage of light oil and tar sands.
But can their marriage last? TransCanada is betting oil prices will go much higher and faster than most forecasts anticipate and that the volumes will be there by the time that the Keystone pipeline is built. Canada would like to build the this pipeline to make sure any expansion of tar sands can deliver them for blending with tight oil.
But Berman questions the longevity of the tight oil plays, since production from both the Bakken and Eagle Ford plays is declining and Permian tight oil production growth has slowed.
U.S. ultra-light oil production is a central component of the global supply dilemma. When tight oil output is high, some fraction can neither be refined nor exported and simply adds to inventories.
An oil crunch surely is coming a few years from now, causing oil prices to rise dramatically. New E&P project investments are being deferred at a time when production from developed fields is accelerating. Improved production efficiency now will just further accelerate reserve depletion and make the decline rate steeper later. Meanwhile, new field discoveries are at the lowest level in decades and their average reserve size has gotten smaller.
The risk for the Keystone XL is that much higher prices will collapse the global economy before new projects can fill the pipeline and pay out the investment.

Art Berman. February 3, 2017. The Keystone XL Pipeline: A Risky Bet on Higher Oil Prices and Tight Oil. artberman.com
The Keystone XL Pipeline (KXL) is a bet on much higher oil prices several years from now. It will take at least $85 oil prices to develop the new oil sand projects needed to fill the pipeline.
It is also a bet that U.S. tight oil output will continue to grow and will need heavy oil to blend for refining. Both bets are risky.
A Bet On Higher Oil Prices
It was not until prices exceeded $70 per barrel in 2005 (December 2016 dollars) that oil sands expansion began to accelerate (Figure 2). Since then, production has almost doubled from 1.3 to 2.4 mmb/d and cumulative production has increased from 5.4 to 10 billion barrels.
By comparison, the Bakken and Eagle Ford tight oil plays have each produced 2.4 billion barrels. The Permian horizontal tight oil plays–Spraberry, Wolfcamp and Bone Spring–have produced less than 1 billion barrels.*
In 2015, oil prices averaged only $43 per barrel. No new oil sand projects have been sanctioned since oil prices collapsed in 2014 although 3 pilot projects have been approved since prices moved into the $50 per barrel range. Approval is not the same as sanctioning and these 3 projects together would add only 35,000 b/d.
It seems unlikely that new greenfield projects will be sanctioned until oil prices move much higher (Canadian heavy oil (WCS) trades at a 25% discount to WTI). Assuming that prices stabilize in the $50 to $60 range, it is reasonable that pilots may evolve into brownfield expansion projects over the next year or two.
The Canadian Association of Petroleum Producers estimates that annual oil sand production will grow 128,000 b/d until 2021 and then, grow more slowly at 59,000 b/d. If all of that new oil were going to KXL, it would not reach capacity for about 10 years. But other pipelines are already approved for expansion and will probably get much of the oil before KXL is completed.
TransCanada’s bet, therefore, is that oil prices will move much higher and more quickly than most forecasts anticipate and that the volumes will be there by the time that the pipeline is built.
Light Oil and Heavy Oil
U.S. tight oil plays produce ultra-light oil. Almost all of it is too light for refinery specifications. That means that it must be blended with heavy oil in order to be refined and that is why there is demand for Canadian heavy oil.
The Keystone XL Pipeline is, therefore, a bet that tight oil plays will continue for several decades.
Similarly, Canadian viscous, heavy oil must be diluted with ultra-light oil to move through pipelines. Because of that, Canada is the biggest importer of U.S. light oil.
The U.S. imports almost 3 times more oil from Canada than from Saudi Arabia (Figure 3). Imports from Canada are roughly equal to the amount from Saudi Arabia, Venezuela, Mexico, Colombia and Iraq combined.
The average U.S. refinery is designed for 31° API gravity oil but 80% of domestic crude oil is more than 30° and 70% is more than 35° API gravity so it must be blended with heavier oil before it can be refined (Figure 4). The Keystone Pipeline carries oil that is approximately 22° API so the fit with lighter U.S. oil is perfect.
The increasing percentage of ultra-light oil (>40° API) after 2011 shown in Figure 4 is because of the growth of tight oil plays. More than 95% of tight oil is greater than 30° API and these plays now account for more than half (52%) of U.S. output.
It is, therefore, no surprise that 98% of the oil imported by the U.S. is heavy that is, less than 35° API gravity (Figure 5). The biggest sources of heavy oil other than Canada are Saudi Arabia, Venezuela and Mexico.
Production from Venezuela and Mexico is declining (Figure 6). Canada, Iraq and Saudi Arabia have strong production histories and are, therefore, more reliable long-term providers of heavy oil to the U.S. Canada has many advantages over other providers because of geographic proximity, supply security and price.
Venezuela has enormous reserves of heavy oil and declining production is mostly because of political and social instability. This could change but it is more likely that Venezuela’s problems will continue. Mexico’s production decline is more systemic because the country has not made a significant new discovery since 1980.
A Bet on Tight Oil
So far, so good for the Keystone XL Pipeline but what about the longevity of the tight oil plays?
Production from the Bakken and Eagle Ford plays is in marked decline and Permian tight oil production growth has slowed (Figure 7). This is despite record high numbers of producing wells in all 3 plays.
The Bakken and Eagle Ford plays have probably peaked based on remaining core area locations, generally poorer performance from recently drilled wells compared to older wells, and current rig activity. Assuming that oil prices recover to the $70 range in coming years, production should increase as more marginal locations become economically viable–just not to peak levels reached in 2015.
The Permian basin, on the other hand, should continue to grow for several years for all of the reasons that the Bakken and Eagle Ford will not. There are substantial areas in the Permian core that have not been fully developed. Well performance continues to improve and the horizontal rig count has increased 70% since mid-August to 243.
Most forecasts are optimistic about tight oil output. The EIA Annual Energy Outlook 2017 anticipates that tight oil production will decline in 2017 but recover to 2015 peak levels by 2019 (Figure 8). WTI oil prices are expected to be $64 per barrel then and slowly increase to $80 by 2025. Tight oil production will rise to 6 mmb/d by 2026.
Although the forecast seems reasonable, it assumes that 2016 was the oil-price floor and that prices will continue to increase. It also suggests that prices will not reach the $70 threshold for new oil sand projects for 5 years. Other forecasts like HSBC are more aggressive and anticipate mid-$70 WTI prices as early as 2018.
The Big Long
If the last few years since the oil-price collapse have taught us anything it is that prices are unlikely to move in one direction. Nor are they likely to conform to mainstream analyst views.
Markets have been driven partly by an expectation that prices must inevitably return to levels of at least $70 to $80 per barrel sooner than later. This belief has endured despite a persistent global supply surplus and outsized inventories. The long-anticipated OPEC deus ex machina was lowered onto the stage in late 2016 and markets responded enthusiastically. Yet WTI prices have not crossed $55 per barrel so far.
It is difficult to find supply-demand fundamentals support even for the limited price rally that began with the OPEC announcement. There may already be an expectation premium of $10-12 per barrel built into current prices. Yet markets don’t always follow fundamentals in the short term although they return to them eventually.
U.S. ultra-light oil production is a central component of the global supply dilemma. Permian basin companies are adding rigs like the boom days of 2011 to 2014 have already returned. When tight oil output is high, some fraction can neither be refined nor exported and simply adds to inventories. This occurs despite the best efforts of Canadian oil sand producers to bring as much heavy oil to the party as they can.
Oil consumption remains relatively weak in the U.S. This is disturbing against the backdrop of surging tight oil rig counts.
Consumption increased with very low oil prices in 2015 and early 2016 but not to the levels before the Financial Collapse of 2007-2008 (Figure 9). Most of the increase was from greater gasoline use and more refined products exports. Modestly increasing prices in 2016 dampened consumption suggesting that demand is highly price-sensitive.
This does not represent peak demand. All credible forecast anticipate oil-demand growth over the next decade or so, albeit at a slower rate. Instead, it reflects an economy weakened by excessive debt and changes in Federal Reserve Bank monetary policy after mid-2014.
These rather gloomy observations may explain TransCanada’s motivation to complete the Keystone XL Pipeline now. I’m talking about a long bet on oil prices.
Future supply constraints will become greater the longer new E&P project investments are deferred. At the same time, the decline of production from developed fields will be more pronounced. Improved production efficiency will further accelerate reserve depletion. Meanwhile, new field discoveries are at the lowest level in decades and the average reserve size of those discoveries has gotten smaller.
Oil prices will increase dramatically at some time in the next several years. That should lead to the next oil boom and the Keystone XL Pipeline will be there to provide heavy oil to U.S. tight oil plays.
There is little doubt that a supply crunch lurks in the future. The risk for the Keystone XL is that much higher prices will collapse the global economy before new projects can fill the pipeline and pay out the investment.
*EIA’s Drilling Productivity Report estimate of 4.8 billion barrels includes all conventional production in the counties in which the tight oil plays are located.
