Since the onset of the downturn in 2014 it has been a pretty bleak few years for the offshore sector, with the occasional chinks of light on the horizon often quickly clouded over. More recently there have been indications that things might be clearing up a little and so sentiment has improved somewhat. But it is worth recalling just how low the barometer has sunk in order to put these things in perspective.

Now that half the year has passed, a review of offshore project sanctioning might be timely. Activity has picked up in 2017, especially for larger projects with CAPEX allocations of at least $500m. The uptick in FIDs has coincided with improved E&P budget guidance from many IOCs. So oil price volatility notwithstanding, could this be an sign of generally improving prospects for larger offshore projects?

Large Projects On The Rise

Offshore field project sanctioning reached a peak of 120 FIDs in 2012. Since then, sanctioning activity has been under pressure from a range of factors, most notably the weaker energy price environment that has prevailed since 2H 2014. Indeed, oil company E&P spending cuts induced by the falling oil price in 2015 precipitated a 33% decline in FIDs that year. Larger projects (with an estimated CAPEX of at least $500m) have been hit the worse, with the number of such developments in 2016 to receive an FID down by 60% on 2012. In comparison, the number of smaller projects sanctioned in 2016 was down by a less severe 32% on 2012.

However, 2017 is (so far) looking rather more promising: 31 offshore field projects received FIDs in 1H 2017, of which 48% were larger projects. Among these were Coral FLNG Ph.1 ($7bn), Leviathan Ph.1 ($3.75bn), Liza Ph.1 ($3.2bn) and Njord A Upgrade ($1.6bn). FIDs have been stimulated by the higher (albeit volatile) oil price, as well as by successes in reducing offshore project costs (by around 30-40% on start 2014, on average).

Small Runs Rule

That being said, while it is true that sanctioning of larger projects seems to be on the rise, it is important to note that many such projects (including all those named above bar Liza Ph.1) were conceived pre-downturn and were on the verge of obtaining an FID in 2014. This implies that the recent uptick in large-project activity may not be sustainable, especially as the backlog of such projects continues to fall. Indeed, the history of start-up delays and cost over-runs at mega-projects such as Kashagan Ph.1 ($48bn) and Greater Gorgon Ph.1 ($55bn) had already prompted operators to rethink the viability of larger offshore projects even before the oil price downturn. Onshore US basins are also potentially problematic for offshore projects, insofar as they compete (quite effectively) for scarce investment dollars.

Efficiency Matters

As a result of these considerations, operators have been downsizing many of the other large-scale projects planned prior to the fall in the oil price. Browse is set to use two FPSOs instead of three FLNGs, for example, while Bonga SW “Lite” now entails an FPSO with a processing capacity 33% smaller than before. Many operators are also placing more emphasis on subsea tiebacks to existing facilities, instead of major new offshore hubs (even if this means lower production volumes). Adapting to the potential “lower for longer” oil price outlook thus seems to be a priority for many upstream players.

So although FIDs at larger projects have picked up, looking beyond the backlog of projects from before the downturn, such developments seem to be less in favour. Scratching the surface, small projects are at least an offshore outlet for upstream investment and in the long run, perhaps cost savings cemented post-2014 might make large projects more competitive.

To much fanfare and accompanied by voluminous industry coverage, Mexico recently concluded Round 1.4, the country’s first ever deepwater licensing round. However, Mexico’s shallow waters may yet have a future too: Bay of Campeche reserves remain considerable and indeed, the country’s third shallow water bid round is ongoing. It is therefore worth reviewing the current state of shallow water E&P in Mexico.

Veering Off Course

Mexican offshore oil is currently produced entirely from shallow water fields, as has always been the case. The key sources of Mexican offshore oil have been several large field complexes such as Cantarell and Ku-Maloob-Zaap. As these fields and others came online, the country’s offshore oil output grew with a robust CAGR of 6.6% from 1980 to 2004, reaching a peak of 2.83m bpd in 2004. As the graph implies, four complexes accounted for 93% of this production. Decline set in thereafter at ageing fields (production at Cantarell began at the Akal field in 1979). Pemex – the sole operator of Mexican offshore fields prior to 2014 – tried to halt production decline, but with little success, given budget and technical constraints. Thus by 2013, offshore oil production at the four key field complexes had fallen to 1.31m bpd, accounting for 69% of Mexico’s offshore oil production of 1.90m bpd.

Getting Back On Track

This situation prompted President Peña Nieto’s government to initiate energy sector reforms in 2013, opening up the country’s upstream sector to foreign companies for the first time since 1938. Pemex was granted 83% of Mexican 2P reserves in “Round Zero” in 2014. The first shallow water round, Round 1.1, followed in December 2014. Only two of 14 blocks were awarded though, reportedly due to unfavourable fiscal terms inhibiting bidding by oil companies. The authorities then improved terms before launching Round 1.2 (shallow water), Round 1.3 (onshore) and Round 1.4 in 2015. Round 1.2 was better received than 1.1: as per the inset, 60% of blocks were awarded (75% of the km2 area on offer). One of the round’s victors, Eni, has already been granted permission to drill four appraisal wells on Block 1.

Turning Things Around?

In light of these positives, there are high hopes for Round 2.1, a shallow water round launched in July 2016. Indeed, 10 out of the 15 Round 2.1 blocks are in the prolific Sureste Basin, home to the Cantarell complex. Eight of these ten areas are unexplored, so there is sizeable upside potential, and have been mapped with 3D seismic, so operators could begin drilling promptly. Moreover, the surface area of the blocks in Round 2.1 are twice that of Round 1.1. It should also be noted that according to a 2016 IEA study, Mexico’s shallow waters still account for 29% of the country’s remaining technically recoverable oil resources. Finally, with rates for a high spec jack-up in the GoM assessed at about $85-90,000/day in January 2017, down 45% on three years ago, some oil companies might be tempted to make a move on a round that could offer a relatively low cost means to grow oil reserves and production.

So arguably, Mexican shallow water E&P is on the road again. There are potential hazards of course, such as oil price volatility or Mexico’s relationship with the US. But it is not implausible to think that Mexican shallow water oil production might speed up again in the coming years.

Plagued by constant blackouts and power shortages, Egypt appears to be facing its worst energy crisis in decades. However, following the historic discovery of the giant gas field Zohr offshore Egypt in August this year and revived interest from IOCs, it seems that the tables are set to turn. Indeed, after a period of gas production decline, Egypt’s energy outlook is getting increasingly bright.

Slide Down The Gas Pyramid

Until recently, Egypt’s gas production story had been one of growth: production climbed from 1.68 to 5.76 bn cfd between 2000-2009 and in 2003, it was sufficient to kick-start LNG exports. However, a combination of political unrest (notably the Arab Spring of 2011) and rising population has resulted in natural gas supply shortages over the last 5 years. Domestic gas demand has on average grown by 8% y-o-y, eventually outstripping supply. As a result, Egypt has been forced to re-route LNG destined for exports to domestic consumption. Indeed, at the start of 2014, BG announced it was breaking its contracts because it was unable to export enough gas. This year, Egypt resorted to importing LNG from Qatar – a bitter moment for the previous exporter.

Enter Zohr

They say that when you hit bottom, the only way is up and for Egypt, this seems to be the case. Earlier this year, ENI made what is believed to be the largest ever gas discovery in the Mediterranean, named Zohr. The field is part of the Levantine Basin, home to other prolific gas finds such as the Israeli Leviathan field. ENI puts the find down to different use of sequencing models, concentrating on carbonate rather than classical sand reservoirs. The gas giant (estimated to hold 30 tcf of lean gas) is located in water depths of 1,450m, providing an exciting departure from typical shallow exploration of mature basins in the region. Additionally, BP announced a $12 billion investment in Egypt’s West Nile Delta project: another deepwater discovery with 5 tcf of gas resources. A move to deeper waters creates opportunity for subsea development, the current production solution of choice in all of the country’s active deepwater fields. Out of the 68 active subsea units in Egypt, 40 are operated by ENI and 8 by BP. It is likely that these operators will continue to implement subsea development in their future projects.

Clash Of The Giants

Elsewhere, the discovery of Zohr was not such welcome news. There were plans to import gas via a pipeline from the Tamar field and (once in production) the competing gas giant, Leviathan, in Israel. Plans for the Leviathan field will now have to be redrawn and potentially accelerated if Israel wants a claim of the region’s LNG exports. However, following extensive regulatory and anti-trust objections, its start-up date remains uncertain.

Nevertheless, it is clear that Egypt’s fortunes are turning. The Zohr discovery, alongside other scheduled start-ups, will strengthen Egypt’s energy balance in the long-term. And the story does not end here: it has been reported that there are 7 other deepwater blocks with similar lithology to ENI’s. There is evidently a revived interest in the Levantine basin, as IOCs begin to wonder where the next giant could be hiding.

On July 14th 2015, after 20 months of negotiations, Iran and the so-called “P5+1” signed the “Joint Comprehensive Plan of Action”: in return for US, EU and UN-mandated sanctions against the country being gradually lifted, Iran has agreed to roll back its nuclear capabilities. Should the deal stick, the door will open to foreign investment once more. What, then, are the possible implications for Iranian offshore oil? Should this deal stick, IOCs will soon be able to operate in Iran once more. What, then, are the possible implications for Iran’s offshore sector?

Political Locks

On the eve of the Islamic Revolution in 1979, total Iranian oil production stood at 6.0m bpd, of which around 12% (0.72m bpd) was from 13 offshore fields producing oil, all located in shallow waters and exploited via fixed platforms. The turmoil of the Revolution saw oil production drop to 1.70m bpd in 1980, and in the ensuing Iran-Iraq War, offshore fields like Salman were shut in due to military action. As a result, actual offshore oil production was less than 50% of capacity for most of the 1980s; after the War, production began to recover, peaking at 88% of capacity (0.60m bpd) in 1997. However, as US and then EU economic sanctions on Iran tightened, IOCs were forced to exit the country, depriving Iran’s offshore sector of key investment and technology. Development work slowed and much of Iran’s offshore 2P reserves (30.3bn bbl of oil; 707 tcf of gas) were locked away. At the same time, Iran lacked the resources to implement EOR at brownfields. As a result, the gap between actual and nameplate offshore production was 1.38m bpd by 2014, with production at 0.54m bpd.

Rusty Hinges

Now that sanctions are to be lifted, indications suggest Iran aims to get as much oil production as possible back onstream in 2015/16. Restoring offshore production is likely to require more than just turning the taps though. Iran’s ability to halt decline at brownfields has been curbed, in contrast to other mature producers like the U.A.E. Half of Iran’s active offshore oil fields predate the Revolution (the oldest started up in 1961). Extensive EOR work is likely to be required at such fields – one opportunity for IOCs. Thus, while offshore production is forecast to grow by 7.3% in 2015, this is mostly due to South Pars condensate production ramping up, rather than utilisation of older capacity.

An Alternative Entrance?

Iran is planning an “oil contract roadshow” in London in 2H 2015, with the stated aim of attracting foreign investment in E&P of $185 billion by 2020. However, it is likely that much of the investment will be directed towards stalled onshore projects such as Yadavaran, and to restoring production at mature onshore fields like Azadegan. A spate of onshore discoveries made from 2006 to 2008 may also be prioritised by cash-hungry Iran, particularly those in the Khuzestan province spanning the Iraq border. Some of Iran’s 7 undeveloped offshore fields like Esfandiar (532m bbl) may warrant priority, and the South Pars Oil Layer is scheduled to come onstream in 2018. But even taking into account the Caspian (home to the 2011 Sardar-e Jangal 500m bbl find), offshore oil opportunities for IOCs (and so vessel owners) may be limited at first.

It seems, then, that the offshore oil capacity gap could widen before it narrows. Certainly given its reserves Iran has long-term offshore potential, notwithstanding its troubled history. But observers expecting a quick and big uptick in oil-related offshore activity might need to be patient.

For many of the markets covered by Shipping Intelligence Weekly, the first part of 2015 was relatively kind. Rates for crude and product tankers were riding high, boxship charter rates picked up for the first time in years and VLGC rates have hit levels above 2014 averages. Even Capesizes have recently shown signs of life. But spare a thought for the offshore sector, the hardest hit by the oil price decline.

Price Drop

Back in the downturn of 2008/09, most commodity and shipping markets felt the negative impact and the offshore markets were no exception, with dayrates dropping by an average of around 35% (see graph).  Moving forward to the current time, however, the 50% decline in oil prices since mid-2014 has brought some relief for merchant vessels, in the form of cheaper bunkers, and stimulated oil demand, helping trade. But cheaper oil has meanwhile put heavy pressure on the offshore sector, where field operators already faced cashflow problems as field developments ran late and over-budget. The response has been sharp cuts in exploration and production (E&P) budgets. It is estimated that spending on offshore E&P will fall by 19% this year.

Investment Cuts

This means investment decisions on new projects have been deferred, whilst expenditure to enhance recovery from existing fields has also slipped. Accordingly, drilling demand has fallen, just as deliveries of new jack-up and floating drilling rigs have accelerated. Rates for ultra-deepwater floaters are now almost 50% below their late 2013 peak, at around $300,000/day. This reflects the reduced demand in frontier areas for exploration and appraisal drilling, not helped by the corruption investigations in Brazil. Meanwhile, jack-up drilling rig rates have been equally hard hit, with shale gas production killing demand in one of their traditional major markets, the shallow water Gulf of Mexico. Utilisation of jack-ups is below 80%, and rates have fallen more than 35% to around $100,000/day.

Less Support For Vessels

This has had rapid knock-on consequences. The 5,365 vessels and 1,133 owners in the OSV market are also exposed to the downturn in exploration drilling and operational field maintenance. Fewer active rigs harms the AHTS market for rig towage and positioning, whilst PSVs rely on the growth in active offshore installations (drilling rigs, plus mobile and fixed production platforms) to add to demand. Rates for OSVs are down in all regions, by over 35% on average in terms of the index on the graph. PSVs have a further problem of a robust supply growth to contend with (and close to 40% of the fleet on order for the largest units over 4,000 dwt).

Of course, markets are cyclical, and the offshore sector had its moment in the sun during 2012/13, at a time when several of the merchant shipping markets were in the doldrums. Although the current oversupply in world oil markets of around 1.5m bpd is a clear short-term hurdle, projected demand trends suggest that higher oil prices remain a likely prospect in the long-term, and the improvement in other sectors suggests that there will eventually be light at the end of the tunnel for offshore too. It’s just that it could be a little way off yet. Have a nice day.

E&P offshore India can be divided into two very distinct species of activity: the one species is typified by shallow water exploration using jack-up drilling rigs, and by multi-phase fixed platform developments; the other species by ultra-deepwater exploration using floaters. The first is concentrated off the west coast, the second off the east coast. But when it comes to CAPEX, which species of activity sits at the top of the food chain in these lean times?

Shallow Water Ancestry

Mumbai High is the ancestor and primordial archetype of the vast majority of field developments offshore India today. Discovered in 1974 in the Mumbai Basin off the country’s west coast, the field was brought onstream in 1976 and was initially exploited via 4 fixed platforms in water depths of around 85m. Subsequent expansions have seen this number rise to 159, with 8 more platforms being fabricated for the Ph.3 redevelopment projects at the field. For the first 30 years of Indian offshore E&P, exploration was focused in the Mumbai Basin while development followed the pattern at Mumbai High. Hence, as of July 2015, 94 fields had been discovered off India’s west coast, all in shallow waters, accounting for 48% of Indian offshore discoveries. Of these 94 fields, 39 are active and 11 are under development. The basin also accounts for 301 active fixed platforms, as well as 13% (18 units) of the jack-up fleet in the Middle East/ISC region. With EOR and redevelopment work underway, the Mumbai Basin remains an important area of offshore activity.

Deepwater Diversification

However, since 2002 the Indian offshore sector has bifurcated to produce a very different species of offshore activity. Exploration campaigns in the east coast Krishna Godavari Basin resulted in 50 new discoveries in water depths >500m (and 51 shallow water finds). Amongst these was KG-DWN-2005/1-A, a field in a water depth of 3,166m, making it the deepest find (in terms of water depth) to date globally. At the height of KG Basin exploration, 12 floaters were active in the country. All this being said, Indian deepwater activity is much less advanced than shallow water E&P: just two deepwater fields are in production and none are currently under development. As a corollary, there are almost no subsea installations offshore India and just one active MOPU.

An Evolutionary Hiatus?

There are, however, 25 ‘probable’ deepwater field developments, including some potentially prolific fields. However, development seems to have been inhibited by the example of KG-D6 (Dhirubhai 1&3), a deepwater (850m) gas field which has shown precipitous production decline. India’s offshore sector is also dominated by indigenous companies like the government-controlled ONGC, who seemingly lack the deepwater technological or operational expertise of many IOCs. At the same time, there are still 88 potential shallow water fields, as well as plenty of scope for EOR at older fields – the sort of projects where Indian oil companies have substantial experience.

Opening up of the upstream sector, as is being attempted in Mexico, might be one means to adapt to the challenges of the “P” of deepwater E&P in India. However, this does not appear to be on the cards for the immediate future. So for the time being, given the hostile conditions of the weaker oil price environment, shallow water activity seems set to thrive best.
