Expectations at the start of the year that 2016 would be a tough one for the oil industry, and in particular for offshore, were on the whole fulfilled. Overall upstream E&P spending globally fell for the second successive year, and was down by in the region of 27% year-on-year in 2016. Cost-cutting has been a key focus, whether that be through pressure on the supply chain, M&A activity, job cuts or other means. OIMT201701

Lower Spending

Offshore spending has been particularly reined back on exploration activity such as seismic survey and exploration drilling, although 2016 saw weakness spread further to areas such as the subsea or mobile production sectors which had initially shown some degree of protection from the downturn. This was not helped by a 32% year-on-year decline in sanctioned offshore project CAPEX in 2016, despite a small number of encouraging project FIDs, such as that for Mad Dog Phase 2 in the Gulf of Mexico in Q4.

Dayrate Weakness

Dayrates and asset values in those offshore sectors with liquid markets showed further signs of weakening in 2016. Clarksons Research’s index of global OSV termcharter rates declined by 27% in 2016, whilst that for drilling rigs was down by 25% year-on-year. Potential for further falls are, in general, limited, given that rates levels in many regions are close to operating expenses. Owners are doing what they can to control the supply side: just 81 offshore orders were recorded in 2016: for context, more than 1,000 offshore vessels were ordered at the height of the 2007 boom. Slippage has also remained evident, either due to mutually agreed delays with shipyards, or owing to owners cancelling orders. Offshore deliveries were 34% lower y-o-y in 2016.

Despite the severe industry downturn, the oil price actually firmed during the year. Brent crude began 2016 at $37/bbl, before briefly dipping below $30/bbl. However, the price ended 2016 at $55/bbl, helped by a slow firming in mid-year, and then more rapid gains after the 30th November announcement of a concerted oil production cut by OPEC countries.

This is clearly positive news for oil companies’ cashflow, and marks the abandoning of Saudi Arabia’s policy of targeting market share by accepting low prices as a means to hinder shale oil production in the US. However, US onshore companies were already feeling more comfortable with slightly improved prices in Q3 2016. Early surveys of intentions for E&P spending suggest that onshore spending in the US could increase by more than 20% in 2017. It is likely that offshore spending will decline further in 2017.

Some Way To Go

Nonetheless, it is important to stress that the offshore sector is far from dead. The expected multi-year downturn is occurring. However, important cost-control and consolidation has taken place. IOCs continue to consider strategic investments such as Coral FLNG or Bonga Lite. This shows that these companies are planning for better times. Decline at legacy fields will help to correct the supply/demand balance. Meanwhile, optimism is building in the renewables and decommissioning markets, with for example, announcements even in the first few days of 2017 that China is to make an RMB2.5 trillion investment in renewables over five years, whilst another North Sea decommissioning project plan has been submitted.

Nevertheless, the supply/demand imbalance in many offshore vessel sectors will take time to recalibrate. However, the weakness of 2016 also put in place many longer term trends which could lay the groundwork for an eventual change in market fortunes.

The North Sea is home to a dispersed mass of steel and concrete, namely: 509 active fixed platforms with a combined weight exceeding 8 million tonnes; 1,440 subsea structures; 9,370 active wells and their completions; and over 45,000km of pipeline. Under the provisions of the OSPAR Convention, field operators will be obliged to decommission and clean all this up one day. And that day is approaching.

Diamonds And Rust

Decommissioning entails plugging wells, removing platform jackets, topsides and subsea structures, and, ultimately, complete site remediation. Oil companies in the North Sea are now having to contemplate this process at fields as recoverable reserves approach depletion. Since first oil in 1967, approximately 54.1bn bbls of oil have been produced in the area. However, production in 2015 is forecast to stand at just 2.86m bpd, compared to the 2000 peak of 5.9m bpd. The value of offshore field infrastructure consists in its ability to assist in the extraction of oil and gas; for the 47% of fixed platform tonnage installed on North Sea fields that began production more than 25 years ago, the point at which this is no longer the case is getting closer. But only 88 platforms in the area have been decommissioned so far, and for good reason.

Worth Fighting For

Decommissioning can be money and time-intensive. The decommissioning of the Brent facilities is expected to take ten years. Even small projects are expected to take two years and more than $300m in CAPEX. Hence, operators are trying to stave off decommissioning through enhanced oil recovery (EOR) to extend field life, or by tying new field developments to existing structures. For example, while the 12 wells on Heimdal are being abandoned, the platforms are being kept to process gas from Vale and other fields.

However, it is thought that in the current oil price environment, OPEX is encroaching on profits at a rising number of fields. Operators striving for fiscal discipline are between the hammer and the anvil: either run fields at a loss, or shut fields down and book the decommissioning costs.

Pain And Pleasure

This choice might be painful for oil companies but there is potential upside for many vessel owners. Drilling rigs and well intervention vessels will be needed to plug many of the wells. Crane vessels, self-elevating platforms and heavy lift vessels will be needed to remove and transport topsides and jackets (indeed, part of the rationale of the “Pioneering Spirit” is that it is one of very few units capable of lifting massive structures like the 42,500t topsides of the “Gullfaks A” gravity base platform). MSVs, DSVs and ROV Support vessels can be used to assist throughout decommissioning and will be especially important for removing subsea structures and for site remediation, when dredgers will also have a part to play. These various vessels will need to be assisted throughout the process by OSVs and utility support vessels.

Oil companies active in the North Sea might prefer not to charter all these vessels just to exit dead fields. But sooner or later (quite possibly sooner) they will have little choice. This could potentially benefit many different owners, with decommissioning becoming an important driver of North Sea vessel demand.

As the recent plunge in oil prices sees some operators tightening their belts and their appetite for exploration seemingly diminishing, can development drilling provide alternative demand amidst the doom and gloom? The North Sea serves as an interesting example of an active drilling market throughout E&P cycles. Could this observation have implications for rig activity within other regions?

Playing The Risk

The assessment of “risk”, both financial and operational, is one of the most important factors for International Oil Companies (IOCs) when considering future projects. In periods of high oil prices, when company revenues are high and debts are low, operators are prepared to take on higher risk, lower margin projects, and are more comfortable in increasing their exposure to exploration. In a low oil price environment however, companies focus on low risk projects and increasing returns on investment, as opposed to riskier exploration operations.

Produce A Winner

This lower tolerance to risk often results in reductions to exploration budgets and activity, in particular drilling operations. In the last 12 months, global drilling rig utilisation has declined from 95% down to 89% as oil prices have declined to under $70/bbl. This trend has been typical throughout history. In 1985-87, historical reports show that global rig utilisation declined drastically from almost 90% to around 50%, following the oil price crash of the mid-80s. Despite this, some areas have fared much better than others through the bust periods

As the Graph of the Month shows, the number of wells drilled per year in the North Sea during the years 1980-98 increased from 335 to 618, despite the oil price declining to $18/bbl (inflation adjusted to 2013 $/bbl). As companies focussed on increasing production from their portfolio of newly discovered fields, increases in development drilling far outweighed declines in exploration work.
Over the same period, the share of development drilling increased from 68% to 86%, and by end-2002 over 90% of wells drilled were for field developments. This increase, throughout a period of depressed oil prices, highlights the need for development work following exploration.

Develop Your Game

In areas where the number of undeveloped fields is high (the North Sea reached an estimated peak of 583 by end year 1992), it is inevitable that development drilling becomes more prominent, as exploration operations become riskier and thus more expensive. Today, areas such as West Africa and SE Asia, where the current number of undeveloped fields total 379 and 506, are examples of this, and could witness an increase in development drilling similar to that seen in the North Sea during the 80s and 90s.

Whilst reduced exploration will likely result in short-term declines in rig utilisation and dayrates, other sources of demand could exist. Though wildcat spuds and discoveries may dwindle in the near term, areas of previously high exploration activity could see alternative demand for rigs through development drilling. After that? Well, perhaps the world will still have to go and find more oil.

‘Pre-salt’ is usually a term associated with Brazil, where giant offshore field discoveries in the Santos and Campos basins have been grabbing headlines since 2007. Now oil companies are looking across the ocean for their pre-salt game. Conjugate basins offshore Gabon, Congo and Angola could be as juicy as the Santos and Campos pre-salt plays have proved. Following a number of recent scores by Cobalt, Eni, Harvest, Maersk and Total, the hunt is on.

Gearing Up

As the Graph of the Month shows, 16 wells targeting West African pre-salt reservoirs have been drilled since start 2011 with a success rate of 75%: 9 offshore Angola, 6 off Gabon and one off Congo. Oil from West African pre-salt was in fact first found in 1968. Its prospective yield was not appreciated though, as only recently did seismic imaging become able to give an accurate picture of the pre-salt. The ultra-deepwater of Angola’s Kwanza Basin also inhibited pre-salt exploration before sixth generation floaters. But, as Brazil has shown, operators now have all the technology they need to pursue the pre-salt.

Hunting Elephants

Some 27 future pre-salt wells are reportedly planned by oil companies or are anticipated through to end 2015, as the Graph of the Month shows. Four of these wells have been spudded. Often smaller E&P companies play a vital role in opening up new frontiers. In West Africa though, supermajors and other large players are already loading up. Conoco has 4 planned wells; Repsol, 3; Eni, 2; Shell, 2; and Total, 2. Of the 27 wells, 70% are offshore Angola and will therefore be in water depths ranging from 800-2,000m. The remainder are to be spudded off Gabon, likely in water depths up to 300m. In either case, companies will be hoping to hit world-class finds, like Cobalt’s Cameia discovery, which is expected to be brought onstream at 80-120,000 bpd in 2017.

Fieldcraft

So, the West African pre-salt play is still in the early stages of exploration and appraisal. If it proves prolific though, and if operators can bring it to fruition, a pre-salt bonanza would more than offset production decline from West Africa’s mature fields. With less stringent local content requirements and more international oil company control, development may be less fraught than in Brazil. Cobalt have already announced plans for 3 multi-field pre-salt hubs centred around the Cameia, Lontra and Orca fields offshore Angola. Given that the average water depth of Angolan pre-salt wells is 1,274m, MOPU solutions are likely to be favoured. The previous caveats noted, the FPSO ordering boom in Brazil could be replicated in Angola, which already accounts for 23% of world FPSO deployment (second to Brazil). In the shallower waters off Gabon, fixed platform solutions are probable, if finds reach the development stage.

In the near term then, the pre-salt safari offshore Africa looks to be an exciting campaign, with potential to generate even more interest in the region and hence opportunities for survey vessel and rig owners. Out towards the end of the decade, Angola could be the new Brazil, with pre-salt development contracts abounding.

OIMT201406

OIMT01Since the start of 2010, the drillship fleet has grown 98% and the number of semi-subs capable of drilling in >5,000ft of water has grown 45%. This suggests increasing demand for rigs capable of drilling in deep and ultra-deep water, but how much is currently taking place at these depths?

Rigs In The Middle

The Graph of the Month shows known current water depths in which active drilling rigs are deployed. Whilst jack-ups dominate shallow depths, floaters are drilling mostly in “midwater” (500-5,000ft), where 57% of semi-subs and 45% of drillships are currently deployed.
In deeper water (5,000-7,500ft), 19 >5,000ft semi-subs and 33 drillships are known to be currently drilling. However, only 10% of the active drillship fleet and only 1% of semi-subs are currently deployed in ultra-deepwater. Overall, this means that only half of the active drillships and less than a quarter (24%) of >5,000ft semi-subs are currently located in deep and ultra-deep water. Only 4% of the current floater fleet are currently deployed in ultra-deepwater.

Deeper Potential

Although the current active drilling fleet contains over 105 floaters capable of drilling in >7,500ft water depths, the graph shows that only 9 floaters are currently deployed at such depths. The remaining rigs are therefore deployed in water depths much shallower than their specifications allow.

For example, of the 25 rigs in the current active fleet capable of drilling in water depths 12,000ft or greater, only 5 are currently known to be drilling in ultra-deep water. Of the remainder, 8 are in deepwater and 12 are in midwater. Despite the fleet’s ability to drill in ultra-deepwater, present demand is at mid- and deepwater depths.
The newer generations of floating MDUs have additional advantages in terms of technological sophistication (such as secondary derricks or drillfloor automation), which can make them attractive to operators that might not necessarily need their full depth capabilities. This can make them attractive in midwater harsh environments (e.g. in the North Sea).

Floater Flexibility

However, demand for ultra-deepwater drilling is increasing and expected to continue growing. Bearing this in mind, the orderbook for rigs capable of drilling >5,000ft remains strong (16 semi-subs of this ability and 76 drillships are currently on order). As ultra-deep fields are increasingly explored and developed it is anticipated that a greater share of floaters will be deployed in deeper water, maximising their capabilities.

Ultra-deepwater is expected to be the most rapid source of future demand growth for floating MDUs. However, mid/deepwater demand will remain important. As shown, the existing fleet and orderbook is well equipped to cater for this shift. Depths in which floaters are deployed in the future depend on whether there is investment in next-generation specialist midwater floaters, equipped with the technical innovations of recent ultra-deep rigs. Alternatively, operators may prefer to add to rig supply for ultra-deepwater drilling, which will still provide options for deployment in a broad range of water depths if required.
