Power plants in Saudi Arabia burned an average 0.4 million barrels per day (b/d) of crude oil in 2018 directly for power generation, the lowest amount since at least 2009, the earliest year that data are available from the Joint Organizations Data Initiative (JODI, Figure 1). According to the JODI data, compared with all other countries, Saudi Arabia burns by far the largest amount of crude oil directly for power generation. Between 2015 and 2017, Iraq used the second-largest amount of crude oil for power generation (over 150,000 b/d on average), but has significantly reduced its direct crude burn since then.
During the summer months, Saudi Arabia typically experiences an increase in electricity consumption as domestic demand for air conditioning rises. Saudi Arabia relies on crude oil and other fossil fuels, such as petroleum products and natural gas, for power generation. Saudi Arabia’s direct crude burn reached a record high during the summer of 2015, averaging 0.9 million b/d from June to August. In comparison, direct crude burn in the summer of 2018 was 41% lower at 0.5 million b/d.
Despite continued, steady increases in both population and electricity consumption, Saudi Arabia managed to reduce its reliance on crude oil for power generation by increasing the use of other energy sources, such as natural gas and fuel oil. Most of the natural gas that Saudi Arabia produces is associated gas, which is natural gas produced along with crude oil from an oil well. In recent years, however, nonassociated natural gas production has increased. The Wasit gas plant reached its full operating capacity of 2.5 billion cubic feet per day (Bcf/d) in 2016. The plant was built to process nonassociated gas, which it is currently processing from the Hasbah and Arabiyah offshore gas fields, both of which began production in 2016. Saudi Arabia is investing in more natural gas processing capacity, including the construction of the Fadhili gas plant, which will be able to process nonassociated natural gas from both on- and offshore fields. The Fadhili gas plant is expected to be completed by the end of 2019 with a capacity of 2.5 Bcf/d. Consumption of natural gas in Saudi Arabia has steadily increased, averaging 10.6 Bcf/d in 2017, the latest year for which data are available (Figure 2).
In addition to natural gas, Saudi Arabia has also been using fuel oil as a partial replacement of crude oil in power generation. High-sulfur fuel oil is a relatively cheap petroleum product that can be used to fuel marine vessels and can also be used for power generation. However, because of environmental concerns and competition with other fuels, fuel oil consumption has been generally declining in most regions in the world. In Saudi Arabia, however, fuel oil consumption rose 25% between 2015 and 2018 to 0.5 million b/d on average, according to JODI data. Some trade press reports indicate that one potential side effect of the upcoming changes to the sulfur limits in marine fuels in 2020 is that the stranded high-sulfur fuel oil could be sent to Saudi Arabia to further replace crude oil in power generation.
With less crude oil directly being used for power generation, more crude oil is available for domestic refining and exports. For many years, Saudi Arabia has been working to increase its domestic refinery capacity. Saudi Arabia is able to process 2.9 million b/d of crude oil domestically, which will rise further after the startup of the 400,000-b/d Jazan refinery, which may come online in 2019. Because of its refinery additions, Saudi Arabia has been able to process more of its crude oil domestically. Crude oil refinery runs averaged roughly 1.8 million b/d in 2009 and subsequently rose to an average of 2.6 million b/d by 2018, according to JODI data (Figure 3).
As a result of increased refinery runs, Saudi Arabia was also able to increase the amount of petroleum products it could export. Exports of petroleum products more than quadrupled between 2009 and 2018, from 0.4 million b/d to 2.0 million b/d. Saudi Arabia exports more diesel than any other petroleum product, averaging 0.8 million b/d in 2018. Gasoline and fuel oil were the next two most exported petroleum products in 2018 at 0.4 million b/d and 0.3 million b/d, respectively. Saudi Arabia also imports petroleum products; however, over the past several years, Saudi Arabia has generally become a net exporter of most products, according to JODI data.
In addition to refining more crude oil domestically, using less crude oil in power generation can enable Saudi Arabia to increase crude oil exports, if needed. However, in late 2016 and in late 2018, Saudi Arabia, along with other members of the Organization of the Petroleum Exporting Countries (OPEC) and some non-OPEC countries, agreed to voluntarily cut crude oil production in order to prevent further declines in crude oil prices. These agreements resulted in lower production of crude oil in Saudi Arabia, which is a more significant factor in how much crude oil the country has available to export throughout the year (Figure 4).
Furthermore, Saudi Arabia has been cutting production beyond its agreed-upon target, meaning that as Saudi Arabia’s crude oil production falls, production of associated natural gas will also decline. Declines in associated natural gas production could result in an increased need for crude oil used for power generation.

The U.S. average diesel fuel price increased more than 2 cents to $3.17 per gallon on April 29, 1 cent higher than a year ago. The Rocky Mountain price increased 4 cents to $3.18 per gallon, the West Coast price increased more than 3 cents to $3.73 per gallon, the Gulf Coast and East Coast prices increased 2 cents to $2.94 per gallon and $ 3.19 per gallon, respectively, and the Midwest price increased nearly 2 cents to $3.06 per gallon.
Propane/propylene inventories rise
U.S. propane/propylene stocks increased by 1.2 million barrels last week to 58.9 million barrels as of April 26, 2019, 10.3 million barrels (21.1%) greater than the five-year (2014-2018) average inventory levels for this same time of year. Midwest, Rocky Mountain/West Coast, and East Coast inventories increased by 0.9 million barrels, 0.2 million barrels, and 0.1 million barrels, respectively, and Gulf Coast inventories increased slightly, remaining virtually unchanged. Propylene non-fuel-use inventories represented 9.6% of total propane/propylene inventories.

U.S. crude oil production in the U.S. Federal Gulf of Mexico (GOM) averaged 1.8 million barrels per day (b/d) in 2018, setting a new annual record. The U.S. Energy Information Administration (EIA) expects oil production in the GOM to set new production records in 2019 and in 2020, even after accounting for shut-ins related to Hurricane Barry in July 2019 and including forecasted adjustments for hurricane-related shut-ins for the remainder of 2019 and for 2020.
Based on EIA’s latest Short-Term Energy Outlook’s (STEO) expected production levels at new and existing fields, annual crude oil production in the GOM will increase to an average of 1.9 million b/d in 2019 and 2.0 million b/d in 2020. However, even with this level of growth, projected GOM crude oil production will account for a smaller share of the U.S. total. EIA expects the GOM to account for 15% of total U.S. crude oil production in 2019 and in 2020, compared with 23% of total U.S. crude oil production in 2011, as onshore production growth continues to outpace offshore production growth.
In 2019, crude oil production in the GOM fell from 1.9 million b/d in June to 1.6 million b/d in July because some production platforms were evacuated in anticipation of Hurricane Barry. This disruption was resolved relatively quickly, and no disruptions caused by Hurricane Barry remain. Although final data are not yet available, EIA estimates GOM crude oil production reached 2.0 million b/d in August 2019.
Producers expect eight new projects to come online in 2019 and four more in 2020. EIA expects these projects to contribute about 44,000 b/d in 2019 and about 190,000 b/d in 2020 as projects ramp up production. Uncertainties in oil markets affect long-term planning and operations in the GOM, and the timelines of future projects may change accordingly.

Because of the amount of time needed to discover and develop large offshore projects, oil production in the GOM is less sensitive to short-term oil price movements than onshore production in the Lower 48 states. In 2015 and early 2016, decreasing profit margins and reduced expectations for a quick oil price recovery prompted many GOM operators to reconsider future exploration spending and to restructure or delay drilling rig contracts, causing average monthly rig counts to decline through 2018.
Crude oil price increases in 2017 and 2018 relative to lows in 2015 and 2016 have not yet had a significant effect on operations in the GOM, but they have the potential to contribute to increasing rig counts and field discoveries in the coming years. Unlike onshore operations, falling rig counts do not affect current production levels, but instead they affect the discovery of future fields and the start-up of new projects.

The API gravity of crude oil input to U.S. refineries has generally increased, or gotten lighter, since 2011 because of changes in domestic production and imports. Regionally, refinery crude slates—or the mix of crude oil grades that a refinery is processing—have become lighter in the East Coast, Gulf Coast, and West Coast regions, and they have become slightly heavier in the Midwest and Rocky Mountain regions.
API gravity is measured as the inverse of the density of a petroleum liquid relative to water. The higher the API gravity, the lower the density of the petroleum liquid, so light oils have high API gravities. Crude oil with an API gravity greater than 38 degrees is generally considered light crude oil; crude oil with an API gravity of 22 degrees or below is considered heavy crude oil.
The crude slate processed in refineries situated along the Gulf Coast—the region with the most refining capacity in the United States—has had the largest increase in API gravity, increasing from an average of 30.0 degrees in 2011 to an average of 32.6 degrees in 2018. The West Coast had the heaviest crude slate in 2018 at 28.2 degrees, and the East Coast had the lightest of the three regions at 34.8 degrees.
Production of increasingly lighter crude oil in the United States has contributed to the overall lightening of the crude oil slate for U.S. refiners. The fastest-growing category of domestic production has been crude oil with an API gravity greater than 40 degrees, according to data in the U.S. Energy Information Administration’s (EIA) Monthly Crude Oil and Natural Gas Production Report.
Since 2015, when EIA began collecting crude oil production data by API gravity, light crude oil production in the Lower 48 states has grown from an annual average of 4.6 million barrels per day (b/d) to 6.4 million b/d in the first seven months of 2019.

When setting crude oil slates, refiners consider logistical constraints and the cost of transportation, as well as their unique refinery configuration. For example, nearly all (more than 99% in 2018) crude oil imports to the Midwest and the Rocky Mountain regions come from Canada because of geographic proximity and existing pipeline and rail infrastructure between these regions.
Crude oil imports from Canada, which consist of mostly heavy crude oil, have increased by 67% since 2011 because of increased Canadian production. Crude oil imports from Canada have accounted for a greater share of refinery inputs in the Midwest and Rocky Mountain regions, leading to heavier refinery crude slates in these regions.
By comparison, crude oil production in Texas tends to be lighter: Texas accounted for half of crude oil production above 40 degrees API in the United States in 2018. The share of domestic crude oil in the Gulf Coast refinery crude oil slate increased from 36% in 2011 to 70% in 2018. As a result, the change in the average API gravity of crude oil processed in refineries in the Gulf Coast region was the largest increase among all regions in the United States during that period.
East Coast refineries have three ways to receive crude oil shipments, depending on which are more economical: by rail from the Midwest, by coastwise-compliant (Jones Act) tankers from the Gulf Coast, or by importing. From 2011 to 2018, the share of imported crude oil in the East Coast region decreased from 95% to 81% as the share of domestic crude oil inputs increased. Conversely, the share of imported crude oil at West Coast refineries increased from 46% in 2011 to 51% in 2018.
