北海和墨西哥灣(GOM)是全球重要的兩個海上油氣產區,昔日這兩個地區的產量占全球海上油氣總產量的20%左右,油氣投資占全球的25%。受低油價影響,如此大體量的油氣區塊曾一度發展停滯,未來將如何重獲繁榮呢?
北海&墨西哥灣:油氣生產趨勢極為相似
從海上油氣生產的歷史數據來看,這兩個地區的趨勢非常相似,它們在2000-2013年間均經歷了產量的大幅減少:北海的油氣產量從1000萬桶油當量/天下降到了600萬桶油當量/天,而墨西哥灣的產量則從400萬桶油當量/天,下降到了200萬桶油當量/天。
從2014年開始,兩個地區產量下降的趨勢均有所改變,產量再次增加。這一結果源自一批新項目的獲批,以及成熟油田的二次開發。在北海,新開發油田包括Knarr、Gudrun、E. Grieg、Laggan和Jasmine油田;二次開發的成熟油田,包括Valhall、Ekofisk和Eldfisk。在墨西哥灣,主要是一些深水項目限制了產量的下降,如Lucius、Jack/St. Malo和Delta House等油田,正不斷成為新的產量來源。

從中期來看,由于近年來獲批項目較少,預計產量將有所下降。北海地區在未來五年的油氣生產下降量可能多達100萬桶油當量/天,而相同時期內,墨西哥灣可能的產量下降量約為30萬桶油當量/天(圖1)。
兩地區的競爭優勢凸顯
當前,北海和墨西哥灣都在同其他油氣資源爭奪投資,因此,有必要考慮兩個地區的競爭力情況。圖2描述了挪威、墨西哥灣和英國新項目,以及其他油氣資源的盈虧平衡價格和投資回收周期。

由圖2可知,挪威和墨西哥灣一些未獲批項目的平均盈虧平衡價格低于50美元/桶,低于未來幾年即將批準的一些其他油氣資源項目。事實上,相比于頁巖氣,挪威項目的盈虧平衡價格還要低10美元/桶。
事實上,正是由于北海和墨西哥灣地區相比于其他地區的油氣資源項目更具有競爭優勢,挪威著名能源咨詢公司Rystad才敢大膽預測,預計未來在這些地區將會上馬一些新項目。隨著獲批項目的增加,到2019年投資也將增加,這將有助于緩解生產遞減造成的產量停滯,最終產量會隨之增加。另外,由圖2可知,北海和墨西哥灣項目的盈虧平衡價格在40-50美元/桶之間。
兩地區發展同步 都獲批了哪些新項目?
1. 新獲批準項目漸增
自2013年以來,兩個地區獲批的項目數量呈下降趨勢。2010-2013年,北海地區每年都有15億桶油當量的新資源項目獲批,而2016年,這一數字僅為2億桶油當量。在墨西哥灣地區,2010-2013年,這一指標平均每年為7億桶油當量,而2016年為3.3億桶油當量,新項目的減少影響了之后的支出和中期產量。
許多項目受低油價影響而延遲,但勘探生產公司通過改變思路,降低了項目相關的成本,Rystad能源公司預計從2018年開始,兩個地區獲批的項目數量會再次增加。此外,隨著油價逐步回升,許多準備中的項目將獲批。在北海地區,未來3年約有20億桶油當量的資源開發項目將獲批,而對于墨西哥灣地區,這一數字為8.5億,也相當可觀。
2. 大型項目有哪些?
圖3統計了未來幾年,預計將獲批的一些大型項目。最大的要數位于巴倫支海的Johan Castberg項目,該項目的作業者為挪威國油,最終將以FPSO(浮式生產儲油)裝置生產,預計在2018年獲得最終的批準。挪威國油及其合作伙伴一直在努力降低該項目的成本,并改變開發思路??偟膩碚f,盈虧平衡價格從80美元/桶下降到了35美元/桶。

第二大項目是Johan Sverdrup二期,二期項目包括一個新的處理平臺和海底基礎設施,未來它們將把產量從約40萬桶/天增加至約60萬桶/天。
Kaskida是墨西哥灣地區即將獲批的最大項目,該項目所在油田為高溫高壓油田,并于2009年被發現。下第三系地層的另一個發現是阿納達科公司的Shenandoah油田,阿納達科將繼續進行評價工作,預計采用半潛式平臺進行開發。
另外兩個有趣的油氣發現是Wisting和Alta/Gohta,連同Johan Castberg,這些項目將使巴倫支海地區成為重要的油氣產區和北極地區重要的區域。為增加這些項目的預計資源量并提高項目的商業性,未來2年在該區域將會新開鉆一批評價井。
油服市場隨油價跌宕起伏
近兩年來,低油價對油服公司造成了極大的影響。北海和墨西哥灣地區的油服公司的收入已經從2014年的峰值減少了42%。在經歷了五年連續以13%的速度增長后,自2015年開始,勘探生產公司縮減了投資,油服市場開始經歷艱難時刻。像NOV、Transocean和Subsea 7等一些公司,收入減少更是超過了50%(圖4)。

2010-2014年間的高油價,助推了墨西哥灣和北海地區許多新油田的開發。一些大的開發項目,如墨西哥灣地區的Jack/St. Malo、Mars B和Big Foot項目,以及北海的Goliat、Martin Linge和QUAD204項目,給油服公司帶來了前所未有的高收入,也催生了油服業的大繁榮。
但2014年新獲批項目數量逐漸減少,再加上許多項目在2015年終結,油服公司在這兩個地區的訂單數量驟減。無獨有偶,其他地區油服公司的業務量減少得更多,如北美陸地,許多公司的收入減少了60%以上。
海上油服市場前景幾何?
盡管油價在2016年有大幅回升,但就油服工作需求量來說,2017年仍然比2016年更疲軟。隨著行業實際服務單價的逐漸降低,預計北美和西歐市場規模將分別收縮15%和7%。
好消息是,在經歷了兩年的項目停滯后,勘探生產公司愿意重新批準一些新項目。一些如Mad Dog二期、Kaikias和Johan Castberg等新項目的獲批表明,油氣公司有能力提高這些地區海上油氣項目的經濟性,并控制項目風險,使它們更具競爭力。
可想而知,這些新項目短期內不可能獲得可觀的回報,想要彌補現有油田支出的減少可能需要一定的時間,但隨著今明兩年油價在50-65美元/桶之間波動,未來可能會有更多的項目獲得批準。
挪威的Johan Sverdrup二期、英國的Rosebank項目,以及墨西哥灣的一些小型水下回接項目的重啟,將共同促使這兩個地區有望從2019年開始利潤大增。
不同部門的市場增長情況各不相同,工程、采購、施工和安裝(EPCI)以及維護、改建和運營這兩大市場似乎最有前途,預計在2016-2022年,平均復合增長率分別為13%和7%。對于其他市場,年增長率預計將在4-6%的范圍以內。得益于項目投資開始大幅向大型的獨立項目傾斜,EPCI市場快速增長,相比許多小型的水下回接項目,EPCI的工作量將會更多(圖5)。

對于早期已經開始復蘇的業務,供應商應該著力于維護和運營市場,預計這一領域將從2018年開始增長。一些新油田項目,如Kraken、QUAD204、Gina Krog和2017年將要投產的Jack二期,將促使公司間簽訂更多新的框架協議。從2018年開始,一些已經被延遲的老油田維護項目將重啟,屆時油服公司將重新公開招標。
另一個將在2018年開始增長的油服市場是水下業務,一些老油田需要進行維護或更換一些海底設施。其他市場預計將從2019年開始增長,屆時新的油氣開發項目將全速啟動。
油服業回暖只能仰仗高油價?
在行業經歷了如此巨大的調整后,需要一段時間才能全面復蘇。即使未來10年油價在90-100美元/桶,市場也無法在2024年之前回到2014年的水平。如果油價長期保持在50美元/桶,油服市場將面臨巨大的挑戰,預計將維持2017年的水平。
目前的情況并不是缺乏待批準的潛在項目,即使是一些一流的項目,也可以改善成本基礎,但由于其復雜性,這并不適用于所有已發現油氣資源而待批準的項目。對于儲量較小的油田、高溫高壓油田、重油和存在其他復雜因素的油田,許多開發項目的盈虧平衡價格通常高于60美元/桶。
因此,要真正看到北海和墨西哥灣地區的油服市場東山再起,油價必須上漲到這一水平之上。如果達不到,那么油服公司就必須在其他地區尋找新的業務增長點了。
New Projects Will Contribute To Growth
Espen Erlingsen and Audun Martinsen, VP Analysis, Rystad Energy
The Gulf of Mexico (GoM) and the North Sea are two of the key global offshore regions. Together these two regions account for about 20% of the global offshore production and represent 25% of global offshore investments. This article will take a closer look at how these regions will develop going forward.
Production
Looking at historical offshore production, the trends have been similar for the two regions. Both the North Sea and GoM experienced a considerable decrease in production from 2000 to 2013. During this period the North Sea production declined from 10 MMboe/d to 6 MMboe/d, while the GoM production declined from 4 MMboe/d to 2 MMboe/d.
?
From 2014 the declining trend was broken for both regions, and production started to increase again. This was a result of the sanctioning of new projects and the redevelopment of mature producing fields. In the North Sea new fields such as Knarr, Gudrun, E. Grieg, Laggan and Jasmine started up, while mature assets such as Valhall, Ekofisk and Eldfisk were redeveloped. In the GoM it was the deepwater projects that halted the production decline, with Lucius, Jack/St. Malo and Delta House being the primary sources of new production.
In the medium term production is expected to decline due to the lack of sanctioning activity over the last few years. The North Sea production could drop as much as 1 MMbbl/d over the next five years, while GoM production could drop about 300 Mboe/d during the same period (Figure 1).
?
Competitiveness
As both the North Sea and GoM are competing with other sources of production for investments, it is important to consider competitiveness. Figure 2 illustrates this by showing the average breakeven price and payback time for different sources of new production compared to new projects in Norway, the GoM and U.K.
Figure 2 shows how the average breakeven prices for nonsanctioned projects in both Norway and the GoM is less than $50/bbl and lower than all the competing segments for projects to be sanctioned in the coming years. In fact, the Norwegian projects have a breakeven price that is $10/bbl lower than shale.
The fact that the North Sea and GoM are competitive with other sources of production is a key reason why Rystad Energy expects activity to improve for these regions going forward. Increased sanctioning activity will result in an increase in investments in 2019. This also will contribute to the stagnation of the production decline and eventually lead to an increase.
Sanctioning activity
Since 2013 the sanctioning activity in both regions has been trending downward. From 2010 to 2013 1.5 Bboe of new resources were sanctioned yearly in the North Sea compared to 200 MMboe in 2016. In the GoM the average was 700 MMboe annually during 2010 to 2013 compared to 330 MMboe in 2016. The reduced activity has affected spending and the medium-term production outlook.
Many projects were delayed due to the low oil price, but as E&P companies improve the concept and reduce the costs associated with these projects, Rystad Energy expects the sanctioning activity in both regions to increase again from 2018. Furthermore, as the oil price gradually improves, many projects are in the pipeline to be sanctioned. In the North Sea, about 2 Bboe of new volumes could be approved over the next three years, while that number is 850 MMboe for the GoM.
?
Figure 3 shows the largest projects that are expected to be sanctioned over the next few years. The single largest project is Johan Castberg in the Barents Sea. The Statoil-operated discovery will be developed as an FPSO unit and could get the final approval in 2018. Statoil and its partners have worked on reducing the costs for this project and have changed the development concept. In total, the breakeven oil price has dropped from $80/bbl to about $35/bbl. The second largest project is Phase 2 of Johan Sverdrup. Phase 2 consists of a new processing platform and subsea infrastructure, which will increase the plateau production from about 400 Mbbl/d to about 600 Mbbl/d.
Kaskida is the largest discovery in the pipeline for upcoming sanctioning in the GoM. This HP/HT field was discovered in 2009. Another discovery in the Lower Tertiary is Anadarko’s Shenandoah discovery. Anadarko is continuing to appraise this discovery and is planning for a semisubmersible development solution.
Two other interesting discoveries are Wisting and Alta/Gohta. Together with Johan Castberg, these projects will transform the Barents Sea to an oil-producing province and a key Arctic region. To increase the resource estimates for these projects and improve the commerciality, several new prospects are being drilled in this area within the next two years.
Spending and oilfield service market
The low oil price environment has affected oilfield service companies dramatically over the last two years. In terms of revenue, companies exposed to the service market in the North Sea and GoM have experienced a decline of 42% from the peak in 2014. After five years of consecutive growth of 13% on average, the market came to a hard stop in 2015 when E&P companies put on the brakes to halt investments. The revenue was reduced by more than 50% for some companies such as NOV, Transocean and Subsea 7 (Figure 4).
The high oil price from 2010 to 2014 stimulated many new field developments in the GoM and North Sea. Large developments such as Jack/St. Malo, Mars B and Big Foot in the GoM and Goliat, Martin Linge and QUAD204 in the North Sea caused a record high inflow of contracts to service companies, which led to one of the largest booms in the service industry. The low volumes of sanctioned projects in 2014 coupled with many projects being completed in 2015 resulted in reduced backlogs for service companies. However, service companies in many other regions experienced larger drops such as onshore North America, where revenues fell by more than 60%.
Although oil prices have recovered substantially during 2016, 2017 still looks to be weaker than 2016 in terms of oilfield service purchases. As effective unit prices in the industry are still falling, the market is expected to contract by 15% and 7% in North America and Western Europe, respectively. The good news is that E&P companies are willing to sanction new projects again after two years of drought. Project commitments such as Mad Dog Phase 2, Kaikias and Johan Castberg show that it is possible for companies to improve the project economics for offshore fields in these regions and make them competitive. It will take some time before these new projects offset the decline of spending in existing fields, but with oil prices hovering between $50/bbl and $65/bbl for this year and next year, there is likely to be much more activity in terms of project sanctioning. Phase 2 of Johan Sverdrup in Norway, the revival of Rosebank in the U.K. and smaller subsea tiebacks in the GoM will stimulate spending growth from 2019.
In terms of the market growth for various segments, the engineering, procurement, construction and installation (EPCI) market and maintenance, modification and operation market looks the most promising, with an average compounded growth of 13% and 7%, respectively, from 2016 to 2022. For the other segments the annual growth is expected to lie in the range of 4% to 6%. The rapid EPCI growth is due to the portfolio of projects being heavily tilted toward larger standalone developments with a large EPC scope rather than many small subsea tiebacks (Figure 5).
For early recovering segments, suppliers should look after the maintenance and operations market, which is expected to grow from 2018 onward. The new fields, such as Kraken, QUAD204, Gina Krog and Jack Phase 2 commencing production in 2017, will generate many new frame agreements. A lot of delayed maintenance at aging fields will be up for grabs by service companies from 2018 onward, when this work is overdue.
Another service segment that will witness growth in 2018 is the subsea market, where brownfield activity will drive intervention and replacement of equipment for subsea installations. For other segments growth is expected from 2019 onward, when the development of new resources is at full speed.
After such a deep cut in this market it will take some time before the industry experiences a full recovery. Even with oil prices of $90/bbl to $100/bbl for the next decade, the market will not be back to 2014 levels before 2024. If oil prices are kept at $50/bbl long term, this service market will remain highly challenged and is expected to stay at 2017 levels. There is not a lack of potential projects to be sanctioned, but even though some best-in-class projects have shown stellar improvement in the cost base, this cannot be enforced for the complete portfolio of discovered but nonsanctioned projects due to complexity. With smaller reserves, HP/HT, heavy oil and other complex factors, breakeven prices are typically above $60/bbl for many developments. Hence, for the North Sea and GoM oilfield service markets to truly see a comeback, oil prices will need to improve above these levels. If not, service companies will need to look elsewhere for growth.?
