In the ancient world, the Fertile Crescent was a semicircle in the easternmost part of the Mediterranean that gave rise to some of the world’s greatest civilisations, including the Egyptian, Mesopotamian, Assyrian, Babylonians and Anatolian empires. In modern times, this stretch of water has been the site of some of the greatest hydrocarbon discoveries in the past decade, transforming the likes of Israel and Egypt from energy importers to energy exporters.
With great potential also comes problems. The major finds – almost all of which are natural gas fields – are clustered some 150km from the land boundaries of Egypt, Israel and Cyprus. Maritime dispute are common in the upstream industry, and are generally solved amicably – either through joint development areas like Malaysia-Thailand or demarcating sea borders, which Cyprus did with Egypt, Lebanon and Israel. However, this region is also home to simmering political tensions, which could cloud future development.
Lebanon last month completed its first offshore oil and gas block tender, awarding two blocks to a consortium of Total, Novatek and Eni. One of those blocks – Block 9 – borders Israeli waters, one of two blocks that overlap a triangular 860 sq.km area that both Lebanon and Israel claim. Crucially, Block 9 is just some 20km from the Karish-Tanin gas field in Israel (with its 2.4 tcf of gas) and 60km from the Tamar field. This hints at good gas potential, but Israel has a long history of conflict with Lebanon. Israel’s described the block sale as ‘blatant provocation’, part of a cadre of recent sabre-rattling statements. This might be defused – like back in 2010 when both countries agreed to a maritime border – but if major oil or gas reserves are found in Block 9, things could get complicated.
Over in Cyprus, Turkey has long protested Cypriot maritime border agreements, seeing them as invalid over the issue of breakaway state Turkish Republic of Northern Cyprus, which only Turkey recognises. Thus far, Cypriot E&P activity has been concentrated in the south, far away from waters around the island’s north that are a political quagmire. Discoveries have been encouraging – the Aphrodite field was discovered in 2011 – but have been dwarfed by giant finds in Egypt and Israel. That changed earlier this month, with Eni and Total announcing a promising new find in the south, just 30km away from Zohr. Estimates on Calypso reserves are still ongoing, but its potential has been described as ‘Zohr-like’. Turkey immediately responded with a statement that it considers Calypso within its boundaries, triggering a rebuke from Cyprus and even Egypt.
In response, Turkish warships repeatedly blocked Eni’s ships from reaching offshore drilling sites. This didn’t happen in 2011 when Aphrodite was being developed, but given the blockbuster size potential of Calypso, things could heat up. Turkey has gone as far as to suggest it will begin offshore surveys in Northern Cyprus in response, another act of provocation that could be worrying given the combative approach of Turkey’s current government.

Less than two weeks ago, the VLCC Navarin arrived at Tanjung Pengerang, at the southern end of Peninsular Malaysia. It was carrying two million barrels of crude oil, split equally between Saudi Arab Medium and Iraqi Basra Light grades.
The RAPID refinery in Johor. An equal joint partnership between Malaysia’s Petronas and Saudi Aramco whose 300 kb/d mega refinery is nearing completion. Once questioned for its economic viability, RAPID is now scheduled to start up in early 2019, entering a market that is still booming and in demand of the higher quality, Euro IV and Euro V level fuels RAPID will produce.
Beyond fuel products, RAPID will also have massive petrochemical capacity. Meant to come on online at a later date, RAPID will have a collective capacity of some 7.7 million tons per annum of differentiated and specialty chemicals, including 3 mtpa of propylene. To be completed in stages, Petronas nonetheless projects that it will add some 3.3 million tons of petrochemicals to the Asia market by the end of next year. That’s blockbuster numbers, and it will elevate Petronas’ stature in downstream, bringing more international appeal to a refining network previously focused mainly on Malaysia. For its partner Saudi Aramco, RAPID is part of a multi-pronged strategy of investing mega refineries in key parts of the world, to diversify its business and ensure demand for its crude flows as it edges towards an IPO.
RAPID won’t be alone. Vietnam’s second refinery – the 200 kb/d Nghi Son – has finally started up this year after multiple delays. And in the same timeframe as RAPID, the Zhejiang refinery by Rongsheng Petro Chemical and the Dalian refinery by Hengli Petrochemical in China are both due to start up. At 400 kb/d each, that could add 1.1 mmb/d of new refining capacity in Asia within 1H19. And there’s more coming. Hengli’s Pulau Muara Besar project in Brunei is also aiming for a 2019 start, potentially adding another 175 kb/d of capacity. And just like RAPID, each of these new or recent projects has substantial petrochemical capacity planned.
That’s okay for now, since demand remains strong. But the danger is that this could all unravel. With American sanctions on Iran due to kick in November, even existing refineries are fleeing from contributing to Tehran in favour of other crude grades. The new refineries will be entering a tight market that could become even tighter. RAPID can rely on Saudi Arabia and Nghi Son can depend on Kuwait, both the Chinese projects are having to scramble to find alternate supplies for their designed diet of heavy sour crude. This race to find supplies has already sent Brent prices to four-year highs, and most in the industry are already predicting that crude oil prices will rise to US$100/b by the year’s end. At prices like this, demand destruction begins and the current massive growth – fuelled by cheap oil prices – could come to an end. The market can rapidly change again, and by the end of this decade, Asia could be swirling with far more oil products that it can handle.

As domestic production continues to increase, the average density of crude oil produced in the United States continues to become lighter. The average API gravity—a measure of a crude oil’s density where higher numbers mean lower density—of U.S. crude oil increased in 2017 and through the first six months of 2018. Crude oil production with an API gravity greater than 40 degrees grew by 310,000 barrels per day (b/d) to more than 4.6 million b/d in 2017. This increase represents 53% of total Lower 48 production in 2017, an increase from 50% in 2015, the earliest year for which EIA has oil production data by API gravity.
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, meaning lighter oils have higher API gravities. The increase in light crude oil production is the result of the growth in crude oil production from tight formations enabled by improvements in horizontal drilling and hydraulic fracturing.
Along with sulfur content, API gravity determines the type of processing needed to refine crude oil into fuel and other petroleum products, all of which factor into refineries’ profits. Overall U.S. refining capacity is geared toward a diverse range of crude oil inputs, so it can be uneconomic to run some refineries solely on light crude oil. Conversely, it is impossible to run some refineries on heavy crude oil without producing significant quantities of low-valued heavy products such as residual fuel.

API gravity can differ greatly by production area. For example, oil produced in Texas—the largest crude oil-producing state—has a relatively broad distribution of API gravities with most production ranging from 30 to 50 degrees API. However, crude oil with API gravity of 40 to 50 degrees accounted for the largest share of Texas production, at 55%, in 2017. This category was also the fastest growing, reaching 1.9 million b/d, driven by increasing production in the tight oil plays of the Permian and Eagle Ford.
Oil produced in North Dakota’s Bakken formation also tends to be less dense and lighter. About 90% of North Dakota’s 2017 crude oil production had an API gravity of 40 to 50 degrees. The oil coming from the Federal Gulf of Mexico (GOM) tends to be more dense and heavier. More than 34% of the crude oil produced in the GOM in 2017 had an API gravity of lower than 30 degrees and 65% had an API gravity of 30 to 40 degrees.
In contrast to the increasing production of light crude oil in the United States, imported crude oil continues to be heavier. In 2017, 7.6 million b/d (96%) of imported crude oil had an API gravity of 40 or below, compared with 4.2 million b/d (48%) of domestic production.
EIA collects API gravity production data by state in the monthly crude oil and natural gas production report as well as crude oil quality by company level imports to better inform analysis of refinery inputs and utilization, crude oil trade, and regional crude oil pricing. API gravity is also projected to continue changing: EIA’s Annual Energy Outlook 2018 Reference case projects that U.S. oil production from tight formations will continue to increase in the coming decades.
