Leveraging our deep expertise in satellite radar imagery, Ursa is able to provide reliable measurements – not extrapolations – across global supply chains day or night regardless of clouds or fog.
For example, when Ursa Cushing measurements are compared to the Energy Information Administration’s (EIA)Cushing numbers, Ursa’s measurements have a 99% correlation to storage, with a >85% accurate build/draw prediction. This allows users to more confidently use Ursa’s builds and draws at key terminals, like Cushing, to make smarter decisions at key times.
For week-over-week change, it is statistically reasonable to trust Ursa’s weekly change measurements within 500,000 barrels (bbls), in either direction. Ursa also monitors 340 of the most material terminals around the globe, totaling over 3.6 Billion bbls weekly.
Let’s focus in on a hypothetical trading scenario in Cushing.
Material Insights before API and EIA
As of October 8th, Ursa began publishing weekly Cushing measurements on Monday mornings at 9:30am EST. Prior to this date, we were publishing Cushing on Thursday mornings.
In comparison, the American Petroleum Institute (API) releases its weekly crude oil inventories report Tuesday afternoons at 4:30pm EST, and the EIA releases its weekly petroleum status report Wednesday mornings at 10:30am EST.
Clearly, timeliness and accuracy are key competitive advantages. As you can see in Figure 1 from the Ursa Portal, Cushing crude oil inventories hit 2018 lows of 23.4 million barrels in the summer and have since reversed course, increasing over 65% to 38.8 million barrels as of November month-end.

Refinery turnaround season and the WTI forward curve shifting from backwardation (when the future price for WTI is lower than the prompt-month price) to contango (when the future price for WTI is higher than the prompt-month price) were two fundamental contributing factors to this recent inventory swing.
Storage inventories typically rise during periods of contango since market participants are incentivized to place barrels in storage and wait until a later date to sell those barrels back into the market at a higher price.
Having a leading indication of such activity in Cushing is extraordinarily valuable when making trading decisions. In future blogs, we’ll take a closer look at the relationship between Cushing inventories and NYMEX WTI futures term structure, as well as its relationship to key Permian locations like Midland and Wichita Falls.
Taking a closer look at Cushing inventories over the last 6 weeks, Figure 2 indicates the fill percentage of Cushing inventories rose from 29.35% to 41.06% – an increase of 40% in just 6 weeks.

Suppose given the timely access to rising inventory measurements, coupled with a seasonality forecast entering refinery maintenance season, you have a bearish view on the market and decide to put on a short -100mb WTI crude oil futures position on Monday Oct 8th leveraging Ursa’s insights. In other words, going short 100 contracts, equivalent to 100,000 barrels.
Figure 3 indicates the timeliness and accuracy of Ursa’s Monday morning Cushing measurements as a leading indicator relative to API and EIA:

Let’s see how that short -100mb WTI crude oil futures position would have performed over this 6-week period.
Scenario 1

Ursa reported at 9:30am Monday Oct 8th a Cushing build of 2.40 million barrels, and as such you enter into a short -100mb WTI crude oil futures position at the close at $74.21/bbl. Eagerly awaiting API’s Tuesday afternoon release, API validates with a 2.30 million barrel build. Feeling confident, you eagerly await the EIA’s 10:30am report, which came right in line at 2.36 million barrel build. At the time of the EIA’s release, WTI was trading at $73.87/bbl, and you would have made a profit of $34,000 thus far.
One hour later at 11:30am, WTI was trading at $73.43/bbl – your position is yielding a $78,000 profit. Closing out your position at the close of business Wednesday Oct 10th at a price of $72.79/bbl, you would have realized $142,000 – not a bad return in 48 hours.
