Brazil’s offshore sector has faced various challenges in recent years but nevertheless still accounts for 11% of all offshore oil production, 20% of all ultra-deepwater fields and 23% of FPSO deployments globally. It also still has significant untapped potential, or at least so many international oil companies seem to think, if the results of the country’s most recent offshore block licensing rounds are any guide.

After three consecutive years of falling offshore project CAPEX, things were a little more positive on the project sanctioning front in 2017, with major developments such as Coral FLNG Ph.1 receiving FIDs and total global offshore project CAPEX rising by 44% y-o-y. Sanctioning sentiment is still well below pre-downturn levels, but the relative positivity seems to be holding, so what might be on the cards for 2018?

China’s rapid economic growth over the last two decades has seen the country’s annual primary energy demand more than triple. Coal aside, the other key fuels powering China’s developing economy have been oil and gas. And while commodity imports have risen, economic growth has also incentivised more E&P activity in China itself. So how are things looking for China’s upstream sector, particularly offshore?

Venerable Ancestry

As of start May 2017, a total of 319 fields had been discovered offshore China (with 163 of these having been brought into production at some point) and around 5% of the active offshore fleet (over 500 units) was deployed in the country. Moreover, in 2017, 15% of total projected Chinese oil and gas production (4.43m boed) is forecast to be produced offshore.

Of course, things were not always thus. While oil extraction in China is thought to date back to antiquity, the modern industry took off during the era of Mao Zedong, in the 1950s and 1960s, with the exploitation of fields in the onshore Songliao Basin, notably the Daqing Complex, by the state. Offshore E&P was minimal before the late 1980s. As was the case in many countries, Chinese offshore oil production began at shallow water fields, in China’s case located in the Bohai Bay, Pearl River Delta and Beibu Gulf areas, which still account for 43%, 32% and 12% of the fields now active off China. A total of 139 offshore fields are in production across these three areas, of which 76% are exploited via fixed platforms. Shallow water E&P heavily influenced the development of the offshore fleet in the country: for instance, 11% of the active global jack-up fleet is deployed off China.

The Deepwater Leap Forwards

In recent years though, the drive to raise production has seen Chinese E&P shift into deeper waters, in mature areas as well as frontiers in the East China Sea, the Yinggeh Basin and the South China Sea. That being said, just 13 fields in depths of at least 500m have been found to date (the first in 2006), of which only two are active: Liwan 3-1 and Liuhua 34-2, both in the Pearl River Delta. Hence demand for high-spec floaters, MOPUs and OSVs remains limited. Deepwater E&P in China was led by IOCs, but then CNOOC began concerted independent efforts. However, this process has been slowed by the oil price downturn, which prompted the NOC to put deeper water projects such as Lingshui 17-2/22-1 and Liuhua 11-1 Surround on the backburner.

Conquering The Seas?

The outlook for Chinese offshore projects seems to have improved since the OPEC deal though, and CNOOC is reportedly planning over 120 offshore exploration wells in the next five years. But there are contrary factors, not least of which is political risk in the East and South China Seas, where China and neighbours such as Japan and Vietnam are engaged in bitter border disputes, notably over the “nine dash line”. Moreover, government plans to increase onshore shale gas output at Fuling and elsewhere may divert investment from costly offshore projects.

So there are clearly risks to continuing E&P off China in more frontier areas. But even as the country’s economy matures, energy demand growth is likely to remain substantial. The fundamentals thus suggest that the onwards march of E&P off China is likely to be far from over yet.


Since 1970, 179 offshore gas fields have been discovered in the Browse and Carnarvon Basins of Australia’s Northwest Shelf. From around 2005, as offshore technology advanced and Asian gas demand rose, operators hatched plans of monstrous magnitudes for these fields. However, in an environment of low oil prices and E&P spending cuts, some of these offshore behemoths now look more endangered.

Taming The Seas

The Australian NW Shelf accounts for about 15% of offshore projects globally with CAPEX of over $5bn. NW Shelf projects tend to be capital intensive, in part because they are remote, with an average distance to shore of 161km. Development thus entails long export pipelines (889km for Ichthys, for example) to onshore LNG plants, or as yet unproven FLNG technology. CAPEX in turn contributes to high project breakeven prices, as does OPEX: for example, OSVs make longer trips for far-from-shore projects. Until recently, high project breakevens stymied final investment decisions (FIDs). However, due in part to cost-saving subsea and cryo-technology, in 2007, Chevron approved Greater Gorgon, a $37bn multi-field project with reserves of 40 tcf. Subsequently, 11 more projects received positive FIDS, including Prelude ($12bn), Pluto ($16bn) and Wheatstone ($29bn).

Teething Problems

Since 2007, 4 of these projects have come onstream and the other 8 are due to begin ramping up 2015-17. However, these 12 projects have not been without their problems. Greater Gorgon, for instance, was first scheduled to start up in 2H 2014, rather than 2H 2015; CAPEX has risen by 49% to $55bn. Meanwhile projects yet to be sanctioned have seen FIDs delayed by operators trying to cut costs. Scarborough, a mooted $19bn FLNG development 286km from shore (which has now been delayed again due to the fall in the oil price) underwent multiple FEED studies following the 2010 pre-FEED. Before circumstances changed, a 2019 start-up briefly looked likely.

Monsters Have Feelings Too

NW Shelf gas projects are thought to be some of the more sensitive globally to the change in the oil price since mid-2014. Greater Gorgon’s breakeven is relatively low for the area, but still stands at $67/boe. Projects further from shore are thought to have higher breakevens, in the $80-100/boe range. No Australian project more than 250km from shore has passed FID, though 50% of those yet to reach EPC exceed this distance, casting doubts on their viability. Since the fall in the oil price, Scarborough’s FID has been postponed to 2017/18; start-up before 2023 is considered unlikely. Other projects facing fresh feasibility concerns include Equus, Browse, Greater Sunrise, Crux and Cash Maple. Indeed, the average slippage for such projects already stands at 40 months. Many may not now come onstream before 2023 and a paucity of start-ups is anticipated in the mid-term, 2018-22, due to delayed FIDs 2014-17.

Clearly, then, remote Australian mega-projects are subject to high costs and breakevens, which increases slippage risk. That being said, the long-term fundamentals of energy-hungry non-OECD economies still suggest remaining NW Shelf gas will be viable eventually. These mammoth projects are not extinct yet.
