RBN gives us this overview of the various API grades of crude now coming on stream. The changes pose problems for some refiners, yet the incentive to accommodate the opportunity of these super light grades, is tremendous. We should see some announcements through this year, as the supply dynamics of sourcing these domestic crudes as feed stocks, overcomes the inertia embedded in previous assumptions about supply. what was previously built, can now be seen in retrospect, as decisions based on different supply profiles, largely formulated under the terms of peak oil and the internationals schemes to enable the malfeasance of oiligarchs.

Charge of the Light Brigade – Turner Mason Assesses the Onslaught of Light Sweet Crudes
published by Rusty Braziel on Sun, 06/16/2013 - 17:10
According to a new study just released by Turner Mason titled “North American Crude and Condensate Outlook” (NACCO), U.S. crude oil production could nearly double between early 2012 and 2022. At least that is the Study’s “high case” production scenario. That is very good news for U.S. refiners. Perhaps less good is the fact that 80% of the volume growth is light sweet crude, super-light crude, or even lighter condensate. How will refiners digest all of this light crude and what impact will the growing supply have on price differentials? What will the surge of light crude mean for waterborne and Canadian heavy crude imports? Today we start a two-blog series that will examine some of the findings of TM&C’s “2013 North American Crude and Condensate Outlook” (NACCO).
We’ve looked at this issue before when we reviewed last year’s study in Turner Mason and the Goblet of Light & Heavy. We described the ‘dumbbelling’ of crude oil supplies in North America: On one end of the API spectrum, U.S. crude getting much lighter and on the other, growth in Canadian imports will be almost exclusively heavy. The previous report also explored the implication for product yields, gasoline and distillate exports, the capacity logjam at Cushing, and the impact on refinery capacity, recognizing that there was a lot of uncertainty hanging over the market.
Some of that fog of uncertainty has lifted over the past few months and the 2013 NACOO pulls recent market developments into an updated view of the crude oil market. We now know that U.S. crude oil production is coming on much faster and much lighter. We know that the Brent vs. WTI differential has already narrowed due to increasing capacity between Cushing/West Texas and the Gulf Coast. And we know that crude-by-rail is here to stay. In the paragraphs below we’ll look at these issues in more detail.
All of these crude supply issues are examined in TM&C’s 2013 North American Crude and Condensate Outlook”, For more information, visit www.turnermason.com or call 877-327-7676.

U.S. Crude Oil Production Growth
The graph below in Figure #1 shows TM&C’s ‘high case’ U.S. crude oil production growth forecast for six key crude grades. The bars show the growth in light sweet crude oil production from a 2012 base. This category includes ‘classic’ light sweet in the green bars (31-42 degrees API), super light sweet in orange bars (42 – 55 degrees API) and condensate in gray bars (55 degrees API or higher). Growth in these three grades is expected to be 4.4 Mb/d from 2013 to 2020, with 65% of the increase coming from light sweets, 25% from super lights, and 10% from condensates. The growth rates for super lights and condensates over 2012 are 185% and 200% respectively.
U.S. light sour and heavy grades are projected to grow, but not nearly as fast as the light sweets. The medium sour category shows the most significant growth (24 – 31 degrees API, =1.0 % sulfur; dark brown area), increasing by about 80%. Light sour (31 – 42 degrees API, =1.0 % sulfur; light brown area) grows by 50%. Growth in U.S. heavy crude oil is insignificant.

The vast majority of the production growth – over 80% – comes from only four production fields: Williston Basin (Bakken), Permian Basin, Eagle Ford and the Gulf of Mexico. The light crude, super-lights and condensates come from the Williston and Eagle Ford, with the Permian also supplying significant volumes of the lighter crudes. The medium sour crude is mostly sourced from growing production from the Gulf of Mexico, which is clearly on the rebound.
Over the next few years, a significant portion of the light crudes and condensates will ‘charge’ into the Gulf Coast region, pushing out light sweet imports by the end of 2013 and then starting to back out light and medium sour grades. This will have a big impact on refinery economics and crude quality differentials that we will explore in part 2 of this blog series.
Canadian Crude Oil Production Growth
The quality of growing Canadian production is at the opposite end of the API gravity spectrum. Almost all of the increase making its way to the U.S. will be bitumen from oil sands. There are two sources for this material. The first is mining – actually digging the bitumen out and processing the oil sands to make bitumen crude, a super-viscous, 8 to 10 API crude that does not flow unless heated, diluted or upgraded. The second is steaming it out – pumping high pressure steam into the oil sands formation down one well so the bitumen will get hot enough to flow where it can be recovered by another nearby well. We’ve covered the bitumen market in a number of blogs including It's a Bitumen, oil - Does it go too far? and Crude Loves Rock’n’Rail – Heat It!
Canada’s numbers are big. Proven reserves are 173 billion barrels, which drastically exceeds U.S. proved reserves at 25 billion barrels, and ranks third in the world behind both Saudi Arabia and Venezuela. Approximately 98% of Canada’s reserves are oil sands.
That translates into equally strong production growth, as shown in Figure #2 below. There is another wrinkle to keep in mind when looking at crude from Canada. Most of the imports are bitumen, and most of the bitumen volumes come along with diluent. That means to get total Canadian imports (shipments) you must add together production plus the diluent volume that was added to make the shipments flow. It is that total shipment number that is shown in Figure #2, which is expected to increase at a 10% annual growth rate for 2013 before dropping to roughly a 5% annual growth rate for the rest of the decade. This represents a shipment increase up to 6.0 million barrels per day in Canada as a result of oil sands development by 2022.

Over the next decade the composition of crude shipped out of Alberta will change. Today the majority of crude shipped is conventional heavy, synbit (“synthetic” crude oil upgraded from bitumen to a 20 degrees API), and dilbit (bitumen + diluent). Growth in the future will be primarily in the form of dilbit. And that has the potential to do interesting things to the quality of the crude generally called Western Canadian Select, or WCS. As dilbit becomes a bigger piece of the WCS pie, the assay will shift towards the “dumbbell” dilbit – more heavy components and more light components with less in the middle. Thus refiners should expect to see increasing concentration of light ends, ‘straight-run gasoline’ (naphtha range material) and resid in WCS over the next decade with distillates drying up. Light ends (NGLs – butanes and lighter) will nearly double which could exceed the capacity of distillation units currently bottlenecked in their stabilization section. Increasing volumes of ‘straight-run gasoline’ will mean more low-octane gasoline blendstocks in a market where gasoline demand is declining. Distillates, a bright spot in the refined product markets will face declining supply. And at the heavy end of the barrel, super-heavy residual oil is expected to increase from 28% to 32%. That has the potential to exceed the capacity of refineries already running heavy crudes that max out capacity of their cokers (a refinery unit designed to process resid).
Charge of the Lights meet Dilbit
The implication of a higher percentage of dilbit in Canadian imports is that Canada’s heavy barrels don’t balance out the charging growth of the light crudes from the U.S. Because of the entrained diluent barrels, it makes the U.S. oversupply of ‘straight run gasoline’ even larger. It certainly makes you wonder about the pricing of WCS as more and more light ends pour into the market.
And there is one more little problem. If you add up all of the crude volumes in TM&C’s U.S. ‘high’ case and the outlook for Canadian imports, there is no way that U.S. refiners can absorb all of this crude oil without huge expansions. That seems to imply that the only way this scenario works is for the U.S. Government to start allowing the export of U.S. crudes to overseas (non-Canadian) markets. We’ll explore that scenario further in Part 2.

The Charge of the Light Brigade was a battle during the Crimean War. Lord Cardigan led the ill-fated light cavalry charge against Russian forces during the Battle of Balaclava on October 25, 1854. The poem "The Charge of the Light Brigade" by Alfred, Lord Tennyson was published just six weeks after the battle. |
