一年一度的APPEA會議如期而至,油氣行業領袖重聚澳大利亞Brisbane。面對全球石油供應過剩的新形勢,澳大利亞油氣行業發展深處變革時期,埃森哲對澳大利亞油氣開發存在的問題進行了深度剖析,號召各生產商、服務方、監管部門以及當地政府加深高效合作,持續保持澳大利亞石油業的競爭力。
油氣資源概述
澳大利亞擁有約1600萬平方公里面積廣闊的沉積盆地,沿海大陸架面積超過陸地面積兩倍以上,水下油氣資源儲量前景可觀。根據澳聯邦工業、旅游和資源部以及澳地質科學局資料,澳大利亞原油已探明儲量為11.08億桶,可銷售天然氣89萬億立方英尺。多年來,澳沿海大陸架陸續不斷地發現新的油氣資源,主要分布在巴斯海峽、西北大陸架和Timor海一帶。澳大利亞西北大陸架和鄰近的高庚地區天然氣藏尤其可觀,該地區是澳大利亞尚未開發的最大的天然氣田,儲量高達12.9萬億立方英尺,其能源價值相當于一個儲量為數十億桶的大油田。
根據美國油氣雜志的報道,澳大利亞擁有亞太地區最大的天然氣儲備。除New South Wales和Tasmania州以外,澳大利亞其他州均有天然氣儲備,其中儲備最豐富的地區位于Carnarvon 盆地西北海上,即知名的澳大利亞西北大陸架地區。其他重要的盆地,包括在中澳的Cooper/Eromanga盆地和Bass/Gippsland盆地均位于澳大利亞南部海上。
澳大利亞是經合組織(OECD)成員國,也是繼卡塔爾、印度尼西亞、馬來西亞之后的全球第四大液化天然氣出口國。2014年,澳大利亞Carnarvon石油公司與其合資方美國Apache能源公司日前在西澳的西北大陸架發現一處油田,這可能是澳大利亞近20年來發現的最大油田。Carnarvon石油公司估計該區域的石油儲量有可能在0.3~3億桶范圍內。
近年來,澳大利亞石油產量持續下跌,其原因眾多,首先,產油盆地如Cooper-Eromanga 和Gippsland 已經歷自然減產。第二,盡管產油盆地如Carnarvon 和Bonaparte 最近幾年石油產量上升,但其增量已被澳國內穩定增長的消費所抵消。第三,澳大利亞稅收體制使得國內生產商對于投資石油生產失去吸引力。澳大利亞進口原油大多數來自阿聯酋、馬來西亞、越南和巴布亞新幾內亞。澳大利亞主要石油生產商也在積極投產新項目,以此希望增加國內原油供應并減少進口。
現狀分析
為挖掘澳大利亞石油業潛力,使其成為全球油氣行業的領導者,當地開發商需重新思考其現有開發模式,有效保護當地共同合作發展的大環境,并使用新技術來實現降本增效。對澳大利亞油氣行業現狀作如下分析:
1. 澳大利亞資源量豐富 但油氣行業發展前途未卜
澳大利亞天然氣資源豐富、已探明石油儲量有限、國內天然氣市場趨于飽和幾乎停滯不前,種種現狀促使開發商將液化天然氣(LNG)出口視作油氣發展的唯一增長點。然而,在最終投資協議(FID)簽訂與項目完工之間,由于諸多因素的共同影響,降低了天然氣市場對天然氣進口國的吸引力。運營成本超過預期,美國出口的LNG在東京灣的進口價低至10-11美元/MMBtu(百萬英熱單位),市場需求下降以及油價的持續走低等多方面因素,最終導致其LNG收益降低。同時,高建造成本進一步拉高了居高不下的澳大利亞勞動力及服務成本,綜合上述市場因素,這些都使澳大利亞東、西海岸的LNG項目遭受嚴重打擊。超過世界平均水平的項目支出,進一步抬高了澳大利亞的LNG的價格,LNG成本處于世界最高位,達到12-16美元/MMBtu。
近期公布的行業報告顯示,低油價與LNG市場飽和的雙重打擊,壓制了石油公司對澳大利亞新項目的投資欲望。很難想象,一旦日本國際石油開發株式會社及殼牌的LNG項目投入生產,對于資源量并不匱乏的澳大利亞來說這將是重創,其油氣行業的利潤增長將無處可尋。澳大利亞現在所面臨的問題并非是其擁有的資源量不足,而是如何實現現有資源的經濟性開發。
2. 東海岸互斥開發模式并存
澳大利亞東海岸的煤層氣-液化天然氣(CSG-LNG)項目成本為40-50美元/bbl,居于世界LNG成本曲線的頂端。油價以自由現金流為基礎,處于保本狀態。這些項目混合了兩種商業性的勘探開發模式:前期高資本支出的大型項目模式與穩步式資本投入的美國非常規油氣開發模式。雖然開發商已發現這種組合的商業模式難以管理,但他們已深陷其中。
油價徘徊于低位,迫使這些開發商尋找新的資金,既投資開發高利潤的項目,同時在滿足持續的資本支出需求和利息支付的同時,給股東支付股息,公司股價同樣也受到一定程度的影響。在初期1000口井的鉆井施工中,開發商已將有效的施工成本降低了20-25%,但與可降本50%的美國非常規油氣開發商相比,這些努力卻顯得微不足道。CSG-LNG開發商鉆井300口/年,進行分區獨立開發,這使得他們難以形成類似美國的規?;_發模式,從而難以達到美國的降本效果。因為在美國,開發商與服務方緊密合作來實現降本效果,但澳大利亞東海岸缺乏這樣的合作環境。
3. 西海岸的大型項目光彩不再
與此同時,澳大利亞西海岸的油田開發現狀也并不樂觀。近年來,新增儲量不足導致原油產量的顯著降低。位于Carnarvon盆地的Stag、Barrow Island、Mutineer Exeter與Fletcher Finucane等成熟油田,其開發成本已提高至60-70美元/bbl。如果政府及開發商不重新審視長久開發戰略,不主動尋求資金投入,未來三年將關停部分甚至全部的油田。
西海岸的天然氣卻面臨著完全相反的問題,雖然其資源豐富,但未得到有效開發。這主要是由于這些天然氣資源多位于離海岸數百里遠的偏僻地區,艱苦的施工環境提高了施工成本,同時限制了各施工方之間的合作。國內天然氣市場的飽和使LNG及浮動式LNG成為唯一可行的開發方式。然而,現有全球天然氣市場情況迫使開發商重新審視其開發模式。
4. 忘掉美國吧 LNG行業的主戰場在亞洲
作為澳大利亞LNG產品的輸出地,亞洲正處于天然氣革命的鼎盛時期。上世紀九十年代,東南亞(SEA)油氣公司經受了國內石油需求暴增的嚴峻挑戰。雖然這些公司不斷開發新的油田,但仍不能滿足其國內原油需求的增長,這也導致了在本世紀初東南亞國家淪為石油凈進口國。到目前為止,東南亞的大部分易采油田已得到了有效開發,僅剩一些小油田及難開發油田(如邊緣油田及深水油田)。
然而,鉆井及設備成本支出僅需降低10%,即可給大量天然氣資源的開發帶來利潤;同時,若能將成本支出降低20%,可開發的油氣資源將會更多。使用小型FLNG設備單元開發這些氣田,能使開發成本降至8美元/MMBtu。如果實現足夠的規模開發,澳大利亞開發商將裝配LNG設備,或是坐等長期合同的簽訂。
5. 降本時期已過?需注重現金流管理
在過去兩年內,澳大利亞各開發商均開展了降本項目,嘗試將油價控制在80-120美元。雖然澳大利亞各公司面臨的問題各不相同,各開發商也面臨著不同的挑戰,但解決方案是唯一的:各公司必須停止進一步控制成本的活動,著手改變投資組合與開發模式,優化與供應鏈及數字化相關的合作環境。
總之,開發商、服務方以及政府部門對上述挑戰的應對方式,將決定澳大利亞油氣行業能否進一步發展以及最終是否能夠成為世界油氣行業的領導者。一年前,就曾有過這樣的質疑:澳大利亞油氣行業是否已準備好,通過各方參與者的通力合作來提高自身生產力和競爭力,大大提高整個油氣行業的利潤?而現在,澳大利亞政府也希望各方能轉變思想,互相合作,為其油氣開發謀劃一條清晰的發展道路。

As oil and gas industry leaders prepare to meet in Brisbane next week for the annual APPEA conference, Accenture challenges producers, service companies, regulators and the government to collaborate more effectively to stay competitive in an oversupplied global market.
For Australia to reach its potential as a leader in the oil and gas industry, local players need to rethink their current operating models, create more supportive ecosystems and invest in new technologies to help drive down costs and increase productivity.
Here’s why:
Australia is resource-rich but has an unclear path to growth
Large gas deposits, limited recent oil discoveries and a saturated and stagnant domestic gas market have left operators with Liquified Natural Gas (LNG) exports as the only means of growth. However between final investment decision (FID) and project completion several factors have conspired to make this market less attractive. The prospect of higher than forecast opex, US gas exports landing LNG at US$10-11/MMBtu in Tokyo bay, weaker demand and a lower for longer oil price will all contribute to lower than expected returns. Compounding these market factors, Australian LNG projects on both coasts have been hit by cost blowouts, in part due to construction coinciding with high oil prices pushing up the already high cost of Australian labour and services. These cost blow outs on projects already expensive by global standards have pushed Australian LNG to the higher end of the global LNG cost curve at around US$12-16/MMBtu.
This scarring experience coupled with the low oil price and saturated LNG market have quelled the appetite for new megaprojects in Australia, as seen in recent announcements. Once INPEX’s Ichthys comes online and Shell’s Prelude is producing, it is difficult to see where growth is going to come from in a country which is by no means resource scarce. The problem Australia faces is not one of resource availability but one of economic extraction of its resources to supply market demand.
East Coast production combines two incompatible business models
East coast Coal Seam Gas (CSG) -LNG operations are at the upper end of the upper end of the LNG cost curve requiring a $40-$50/bbl. oil price to breakeven on a Free Cash Flow basis. Such projects blend two Exploration & Production business models into one; the high up front debt-financed capex of megaprojects with the treadmill sustaining capex of US unconventionals. Players around the world have found this blended model difficult to manage. However CSG-LNG players are now trapped in such a model within a single asset. The persistently low oil price is leaving such companies struggling to find cash flow to invest in higher margin projects or payout dividends to shareholders once sustaining capex requirements and interest payments have been met. Share price has been impacted. These operators have been relatively successful at reducing well costs with up to 20 to 25 percent reduction experienced over the first 1000 wells drilled. However compared to the US unconventional players who have achieved up to 50 percent reduction in well cost, such efforts fall short. CSG-LNG players operating in isolation (drilling ~300 wells/year) are unlikely to have the scale and associated learning curve which made such a reduction possible in the US. Whereas the US players have worked closely with services companies to achieve their successes, east Australian CSG does not currently have a comparable ecosystem to support such collaboration
The West coast has lost its lustre for mega projects
Meanwhile on the west coast the situation is not much brighter. A lack of oil discoveries in recent years is leading to significant oil production decline. The lifting cost of mature oil fields such as Stag, Barrow Island and Mutineer Exeter and Fletcher Finucane in the Carnarvon basin is reaching the point where profitability is only reached at $60-70/bbl. Without a rethink of the strategy for life extension and the willingness to expend precious capital, some or all of these fields may be shut in in the next three years.
Gas has the reverse problem, the west coast basins are awash with undeveloped resources – and this is for a reason. Resources are often hundreds of miles from shore in remote areas of Australia in an operating environment of endemic high costs and limited cross-operator collaboration. The saturated domestic gas markets leaves LNG and often Floating LNG as the only viable means of exploitation. However the recent blowouts and current market conditions have made operators rethink development options.
Forget the US, LNG competition could come from Asia
The destination for Australian LNG cargoes, Asia, could itself be on the cusp of a gas revolution. Since the 1990s, South East Asia (SEA) oil and gas companies have been challenged to meet rising domestic demand by consuming domestic petroleum resources. Although SEA oil and gas companies have continued to discover new fields to increase production, efforts were insufficient to meet the growing demand causing SEA to become a net importer in the early 2000’s. To date, most of the easy-to-produce resources have been developed, leaving SEA with dwindling reserves and more technically difficult challenges such as marginal fields and deepwater.
However, a mere 10 percent reduction in wells and facilities costs would unlock significant Gas resources, whilst a 20 percent decrease would unlock even more of Oil and Gas resources. Developing and producing such gas fields through small FLNG units could break even at as low as $8/MMBtu. If sufficient scale is achieved, Australian producers could struggle to place LNG or be left producing into long-term contracts at uncompetitive prices.
The time for cost reduction is over, the time for cash flow management has begun
Within the past two years, each Australian operator has gone through a program of cost reduction, trying to manage an organization accustomed to oil prices in the $80-$120 range. The issues facing Australian companies (or regional affiliates) are diverse and each operator faces its own particular challenges yet the panacea is one and the same. Companies must stop tackling costs in the execution space and start looking at changing business fundamentals around their portfolios and operating models and improve the enabling environment around the supply chain and use of digital.
How operators, the services sector and government respond to these challenge will determine whether Australia is ready to step up and become a leader in the oil and gas industry. Twelve months ago we asked: is the Australian oil and gas industry ‘Ready or Not’, and outlined the significant benefits which could be gained if industry participants collaborated to improve capacity, capability and competitiveness. Today we encourage industry leaders to say, we are ready to think differently and work together to map out a clear path to growth.
