阿根廷“唤醒”Vaca Muerta页岩以增加石油和天然气产量

乔纳森·吉尔伯特,彭博社 2023 年 2 月 27 日

(彭博社)“在布宜诺斯艾利斯西南部一片狂风肆虐的沙漠中,校车长度的黑色钢管一直延伸到地平线。这一场景是迄今为止最明显的迹象,表明世界上最大的页岩油田之一终于有机会兑现其承诺。

在名为 Vaca Muerta 的地质构造中,工人们正在修建一条 356 英里(573 公里)长的管道,将天然气从偏远的巴塔哥尼亚北部输送到阿根廷东部的城市和工业中心。该项目以及同一地区石油管道的扩建计划,将有助于缓解阻碍该国提振经济急需的石油和天然气生产的瓶颈。

尽管阿根廷的能源工业近年来出现了一些虚假的曙光,但该管道的建设是朝着减少该国对燃料进口的依赖,甚至可能恢复其所拥有的地位这一长期目标迈出的无可辩驳的一步。 20 年前作为主要能源出口国。

瓦卡穆尔塔项目取得进展之际,美国页岩油热潮放缓、乌克兰战争扰乱了全球天然气市场,以及世界石油生产增长中心转向包括圭亚那和巴西在内的南美洲。尽管政府对原油价格和资金流动进行限制,但这种情况仍在发生。

“正在采取关键步骤,不会缺少任何基础设施来维持瓦卡穆尔塔在中短期内的增长,”伍德麦肯兹石油和天然气研究员马塞洛德阿西斯说。里约热内卢。但仍然存在地上风险。价格上限是选举周期的一项政策,但钻探商需要长期稳定,而资本管制是一个杀手。”

去年年底的一个早晨,在瓦卡穆尔塔,工人们焊接了巨大的钢管,挖掘了大块沙土,开辟了一条跨国路线,这条管道“以前领导人内斯特·基什内尔的名字命名”将走的路线。许多人认为,这是阿根廷几十年来第一条主要天然气管道。

该管道的开发商、国有的阿根廷能源公司计划在 6 月 20 日之前完工。在经历了多年的挫折(包括疫情和腐败指控)之后,该管道的启动有望成为某种意义上的胜利。更值得一提的是阿根廷国营钻探公司 YPF SA 的几近违约。

6 月 20 日正值阿根廷冬季初,天然气需求猛增,这是一场与时间的赛跑。政府押注该管道将按期完工,因此在未来几个月仅订购了 30 批液化天然气 (LNG) 货物,比去年少了 11 批。任何迫使额外进口的延误都会消耗宝贵的政府资金,在官员们将液化天然气储蓄用于主权债券回购之后,这将是一个令人尴尬的失误。

去年冬天,阿根廷的天然气产量达到每天 1.4 亿立方米 (4.9Bcf),新管道将额外提供 2100 万立方米的运输能力,使页岩钻探人员能够提高作业量。按照逻辑,最终该国将通过陆路向邻国巴西出口液化天然气货物,并通过海运向世界其他地区出口。相比之下,西德克萨斯州和新墨西哥州的二叠纪盆地——世界上页岩地层最丰富的地区——每天抽水量约为 22 Bcf。

尽管阿根廷尚未拥有任何液化天然气出口终端,但总部位于德克萨斯州的 Excelerate Energy 和 Transportadora de Gas del Sur SA 将在未来几周内决定是否建造一个小型终端。YPF 和马来西亚国家石油公司正在研究建设更大设施的可行性。

至于对巴西的出口,他们依赖阿根廷吸引贷款人为内斯特基什内尔管道的额外部分提供资金。这还不确定:阿根廷的困境在很大程度上使其无法进入国际信贷市场,并且它用税收收入支付第一部分,其中包括一次性的大流行财富税。每个部分将耗资约 25 亿美元,总计 50 亿美元。

与此同时,瓦卡穆尔塔的石油产量也将有所增加。运输该地区大部分供应品的 Oldelval SA 和储存公司 Oiltanking Ebytem SA 计划在政府去年更新运营许可证后将产能增加一倍。

现在正是好时机:距离石油需求峰值尚有一段距离,而美国页岩油产量增长也更加缓慢,瓦卡穆尔塔的机会之窗已经打开,因为除了欧佩克之外,几乎没有其他供应可以很快进入市场。

Vaca Muerta 多年来的效率提升意味着一些原油钻探商可以以低至每桶 30 美元的价格实现收支平衡。这将使他们与美国页岩油竞争对手平起平坐

内乌肯省省长奥马尔·古铁雷斯表示,“通过这些管道计划,我们将轻松实现到 2030 年页岩油日产 100 万桶的目标。” 古铁雷斯说,其中大约一半可以运送给国际买家。

截至去年底,内乌肯盆地的日产量达到创纪录的 373,000 桶,几乎占阿根廷石油总产量的三分之二。但在其巨大的石油和天然气储量吸引了雪佛龙公司和壳牌公司等公司十年后,瓦卡穆尔塔的产量仍然无法与二叠纪盆地的供应相匹配。

奥尔德尔瓦尔已经在向页岩钻探商拍卖额外的空间,其中一些钻探商甚至采用卡车将页岩油运往大西洋海岸,这是运输紧张的明显迹象。

阿根廷政府人为地压低国内燃油价格以保护消费者,这往往会损害生产商的利益。旨在捍卫比索的货币管制使该国的钻探商难以获得购买设备或向投资者输送利润所需的美元。当地炼油厂拥有优先购买权,否则可能会在海外卖到更高的价格,这是长期出口合同的障碍。这些措施一直是瓦卡穆尔塔发展的主要障碍。

尽管如此,页岩油领域排名前三的原油生产商 Vista Energy 首席执行官米格尔·加卢西奥 (Miguel Galuccio) 表示,这次可能会有所不同。

“管道项目的进展是吸引更多投资并有可能使阿根廷成为相关能源出口国的关键,”加卢乔说。

Argentina “awakens” Vaca Muerta shale to increase oil and natural gas production

Jonathan Gilbert, Bloomberg February 27, 2023

(Bloomberg) — In a windswept desert southwest of Buenos Aires, black steel tubes the length of school buses extend in a line toward the horizon. The scene is the clearest sign yet that one of the world’s biggest shale plays finally has a shot at living up to its promise.

Workers in the geological formation known as Vaca Muerta are building a 356-mile (573-kilometer) pipeline that will carry natural gas from remote northern Patagonia to Argentina’s cities and industry centers in the east. The project, along with the planned expansion of an oil conduit in the same area, will help relieve bottlenecks that have stifled oil and gas production the nation desperately needs to bolster its economy.

While Argentina’s energy industry has seen its fair share of false dawns in recent years, construction of the pipeline is an irrefutable step toward a much-cherished goal of cutting the country's dependency on fuel imports — and perhaps even regaining the status it held 20 years ago as a key energy exporter.

The progress in Vaca Muerta comes as the U.S. shale boom slows, the war in Ukraine roils the global gas market and the world’s centers of oil-production growth shift to South America, including Guyana and Brazil. It’s also happening despite government restrictions on crude prices and money flows.

“The critical steps are being taken — there’ll be no piece of infrastructure missing to sustain Vaca Muerta growth in the near-to-medium term,” said Marcelo de Assis, an oil and gas researcher for Wood Mackenzie in Rio de Janeiro. “But there are still above-ground risks. Price caps are a policy for election cycles, yet drillers need long-term stability, and capital controls are a killer.”

In Vaca Muerta one morning late last year, workers soldered giant steel pipes and excavated chunks of sandy earth, carving out the cross-country route that the pipeline — named President Nestor Kirchner, after the former leader — will take. By many accounts, it’s Argentina’s first major gas duct in decades.

The conduit’s developer, state-owned Energia Argentina SA, plans to have it ready by June 20. The duct’s startup promises to be a victory lap of sorts after years of setbacks, including the pandemic and allegations of corruption — not to mention the  near-default of Argentina’s state-run driller, YPF SA.

It’s a race against time since June 20 falls early in Argentina’s winter, when gas demand jumps. The government, betting that the pipeline will be finished on schedule, has ordered just 30 liquefied natural gas (LNG) cargoes for the coming months, 11 fewer than last year. Any delay that forces extra imports would eat into precious government funds, which would be an embarrassing misstep after officials used LNG savings for a sovereign bond buyback.

Argentina’s natural gas production reached 140 million cubic meters (4.9Bcf) a day last winter and the new pipeline would provide an extra 21 million of transport capacity, allowing shale drillers to ramp up operations. Eventually, the logic goes, the country would export to neighboring Brazil by land and to the rest of the world by sea in the form of LNG cargoes. By comparison, the Permian basin of West Texas and New Mexico — the world’s most prolific shale formation — pumps about 22 Bcf a day.

Though Argentina doesn’t have any LNG export terminals yet, Texas-based Excelerate Energy and Transportadora de Gas del Sur SA will decide in the next few weeks whether to build a small-scale one. YPF and Malaysia’s Petroliam Nasional Bhd. are studying the feasibility of a bigger facility.

As for exports to Brazil, they depend on Argentina luring lenders to finance an extra section of the Nestor Kirchner duct. That’s no sure thing: Argentina’s woes largely keep it locked out of international credit markets, and it’s paying for the first section with tax revenues, including a one-off pandemic wealth tax. Each section would cost about $2.5 billion, for a total of $5 billion.

Vaca Muerta’s oil production, meanwhile, is also set for a boost. Oldelval SA, which transports most of the region’s supply, and storage company Oiltanking Ebytem SA are planning to double capacity after the government renewed their operating licenses last year.

It’s good timing: With peak oil demand still a way off and U.S. shale production growing more slowly, a window of opportunity has opened for Vaca Muerta since there are few additional supplies beyond OPEC that can come to market soon.

Years of efficiency gains in Vaca Muerta mean some crude drillers can break even at as low as $30 per bbl. That would put them on a par with shale rivals in the U.S.

“With these pipeline plans, we’ll comfortably reach the goal of one million barrels a day of shale oil by 2030,” said Omar Gutierrez, the governor of Neuquen, the province with the lion’s share of Vaca Muerta. About half of that could be shipped to international buyers, Gutierrez said.

The Neuquen Basin was producing a record 373,000 bpd at the end of last year, almost two-thirds of all the oil in Argentina. But a decade after its massive oil and gas reserves lured the likes of Chevron Corp. and Shell Plc, output from Vaca Muerta still doesn’t come close to matching supply from the Permian.

Oldelval has already been auctioning off the extra space to shale drillers, some of whom — in a clear sign of the transportation squeeze — have even resorted to taking shale oil to the Atlantic coast in trucks.

Argentina’s government keeps domestic fuel prices artificially low to protect consumers, often hurting producers. Currency controls, designed to defend the peso, make it hard for the country’s drillers to get the U.S. dollars they need to buy equipment or send profits to investors. And local refiners have right of first refusal to buy oil that might otherwise fetch higher prices overseas, a hurdle to long-term export contracts. Those kinds of measures have been major hurdles to Vaca Muerta’s development.

Still, Miguel Galuccio, CEO of Vista Energy, a top-three crude producer in the shale patch, says this time could be different.

“Progress of pipeline projects is key to attracting more investment and potentially leading Argentina to be a relevant energy exporter,” Galuccio said.
