Opinião: Passado, presente e futuro
É véspera de Natal e – tal como Ebenezer Scrooge, na história de 1843 de Charles Dickens, Um Conto de Natal – a indústria de petróleo tem sonhos perturbadores. O Fantasma do Natal Passado lembra Scrooge que o amor ao dinheiro o impediu de fazer um casamento feliz. O Fantasma do Presente de Natal avisa sobre o desastre, a menos que ele mude de rumo. E o fantasma do Natal que ainda está por vir revela que ninguém se importa com sua morte. A alegoria moral e política de Dickens ressoou ruidosamente, 180 anos depois, na Cop 28, conferência climática realizada pela Organização das Nações Unidas (ONU) em Dubai, enquanto os participantes debatiam se deveriam se comprometer com uma "eliminação progressiva" dos combustíveis fósseis.
O setor defende vigorosamente seu papel no futuro, prevendo uma vida mais longa e um declínio mais lento do que muitos acreditam ser compatível com os objetivos do Acordo de Paris. "Há uma demanda de petróleo e gás hoje e haverá no futuro", afirma o presidente da ExxonMobil, Darren Woods. "Basicamente, produziremos mais petróleo a um custo menor, de forma mais eficiente e com menos pegada ambiental. Esta é uma situação em que todos ganham."
O Cop 28 chegou a um consenso desconfortável, pedindo uma "transição para longe" dos combustíveis fósseis, que alguns ridicularizaram como um "Cop Out" (expressão em inglês para uma desculpa insatisfatória). No entanto, a indústria da commodity já se encontra no meio de uma transição, à medida que a atividade de exploração abranda, os horizontes de investimento diminuem e as empresas aumentam de tamanho através de fusões e aquisições para reduzir custos e serem mais competitivas. A expectativa de vida das reservas de petróleo upstream caiu pela metade: de 50 anos, há uma década, para 25 anos neste ano, informa o relatório Top Projects de 2023, do banco norte-americano Goldman Sachs. E, embora os gastos com upstream tenham se recuperado desde o colapso em 2020 e 2021, este novo ciclo é muito diferente do anterior, com o óleo de xisto norte-americano de ciclo curto agora em "modo de produção" e o ciclo mais longo, em águas profundas offshore, focado em desenvolvimentos de baixo custo, apontou a 39ª pesquisa de gastos com exploração e produção (E&P) do banco britânico Barclays.
As curvas futuras já refletem mudanças nas perspectivas do futuro do petróleo. Os preços do petróleo WTI a longo prazo subiram cerca de $10/b em comparação com o ano anterior, ao passo que os mercados consideram curvas de custos de oferta mais acentuadas. Após uma década de expansão dos recursos, devido principalmente ao óleo de xisto dos Estados Unidos, com curvas de custos mais longas e planas, a curva de custos do petróleo do relatório Top Projects, da Goldman Sachs, recuou desde 2017, tornando-se novamente mais curta e íngreme. O óleo de xisto dos EUA já não é um setor em expansão, com os acionistas buscando melhores retornos e os preços de equilíbrio para a perfuração de novos poços subindo devido à inflação e aos custos de capital mais elevados. E a reserva de projetos em águas profundas está recuando, com as empresas procurando pontos de equilíbrio mais baixos, de cerca de $50/b, para conter os riscos de investimentos de ciclo mais longo.
Ao contrário do petróleo, a curva de custos para zerar emissões de carbono está se tornando mais longa e plana, conforme a tecnologia melhora e os custos de capital diminuem – especialmente no extremo mais alto da curva de custos, afirma o relatório Carbonomics, de 2023, da Goldman Sachs. A conta para eliminar os 50pc mais baratos das emissões globais de gases de efeito de estufa se manteve perto de $1 trilhão nos últimos cinco anos. Mas a conta para alcançar a descarbonização de 75pc caiu quase metade, para $3,2 bilhões até 2023, ante $5,7 bilhões em 2019. E se o fornecimento de petróleo continuar mais caro e a redução de carbono mais barata, o argumento econômico para uma "transição" dos combustíveis fósseis deverá ser irresistível. "Mantenha sua mente aberta para uma variedade de soluções diferentes", diz Woods.
Como sempre, Dickens tem a resposta. "Viverei no Passado, no Presente e no Futuro!", exclama Scrooge, quando acorda de seus sonhos. "Os Espíritos de todos os Três lutarão dentro de mim."

Iran's president dies in helicopter crash
Dubai, 20 May (Argus) — Iran's president Ebrahim Raisi has died in a helicopter crash alongside his foreign minister Hossein Amir-Abdollahian, state media reported early today. The two were confirmed dead more than 12 hours after news broke on 19 May afternoon that a helicopter carrying them had suffered "a hard landing" in Iran's East Azerbaijan province as he was returning from Azerbaijan, where he had inaugurated the Qiz Qalasi dam, alongside his Azeri counterpart Ilham Aliyev. "Ayatollah Seyed Ebrahim Raisi, the eighth president of the Islamic Republic of Iran, who had an air accident on Sunday evening as he was returning to [the Iranian city of] Tabriz from the inauguration ceremony of the Qiz Qalasi dam…reached martyrdom, along with his companions," Iran's state news agency Irna reported. The governor of Iran's East Azerbaijan province, Malek Rahmati, and Ayatollah Mohammad Ali al-Hashem, the representative to the province of Iran's supreme leader Ayatollah Ali Khamenei were also on board the helicopter. More than 50 search and rescue teams were dispatched, with support from allied countries, including Russia. Moscow said on 19 May it had sent 47 specialists, all-terrain vehicles and a BO-105 helicopter. Difficult weather conditions, nightfall, and the mountainous terrain had "complicated efforts" by the search and rescue teams to first locate the exact site of the crash, and then reach it, said Iran's interior minister Ahmad Vahidi. But officials on 20 May reported that the search had narrowed, with the head of Iran's Red Crescent Pir Hossein Kolivand confirming at around 06:00 local time (02:30 GMT) that the wreckage had been found. On arriving at the site, rescuers confirmed that there were "no signs of life." Images shared by state media showed only the helicopter's tail had remained intact, with the entirety of the helicopter's cabin significantly damaged and charred. The investigation into the cause of the crash is continuing, but all Iranian officials are pointing to the bad weather as the primary reason for the helicopter losing control. Iran's cabinet held an extraordinary meeting in the aftermath of announcement of the president's death. This was chaired by the country's first vice president Mohammad Mokhber, who will assume the president's powers and functions with the approval of the supreme leader, as per the constitution. A council, consisting of the speaker of the parliament, head of the judiciary and the first vice president, will now be obliged to arrange for a new president to be elected within a maximum of 50 days. This requires that an election now be held on or before 9 July. By Nader Itayim Send comments and request more information at feedback@argusmedia.com Copyright © 2024. Argus Media group .

Houston refiners weather hurricane-force winds: Update
Houston refiners weather hurricane-force winds: Update
Adds Calcasieu comment, update on flaring reporting Houston, 17 May (Argus) — Over 2mn b/d of US refining capacity faced destructive winds Thursday evening as a major storm blew through Houston, Texas, but the damage reported so far has been minimal. Wind speeds of up to 78 mph were recorded in northeast Houston and the Houston Ship Channel — home to five refineries with a combined 1.5mn b/d of capacity — faced winds up to 74 mph, according to the National Weather Service . Further South in Galveston Bay, where Valero and Marathon Petroleum refineries total 818,000 b/d of capacity, max wind speeds of 51 mph were recorded. Chevron's 112,000 b/d Pasadena refinery on the Ship Channel just east of downtown Houston sustained minor damage during the storm and continues to supply customers, the company said. ExxonMobil's 564,000 b/d Baytown refinery on the Ship Channel and 369,000 b/d Beaumont, Texas, refinery further east faced no significant impact from the storm and the company continues to supply customers, a spokesperson told Argus . Neither Phillips 66's 265,000 b/d Sweeny refinery southwest of Houston nor its 264,000 b/d Lake Charles refinery 140 miles east in Louisiana were affected by the storm, a spokesperson said. There was no damage at Motiva's 626,000 b/d Port Arthur, Texas, refinery according to the company. Calcasieu's 136,000 b/d refinery in Lake Charles, Louisiana, was unaffected by the storm and operations are normal, the refiner said. Marathon Petroleum declined to comment on operations at its 593,000 b/d Galveston Bay refinery. Valero, LyondellBasell, Pemex, Total and Citgo did not immediately respond to requests for comment on operations at their refineries in the Houston area, Port Arthur and Lake Charles. A roughly eight-mile portion of the Houston Ship Channel from the Sidney Sherman Bridge to Greens Bayou closed from 9pm ET 16 May to 1am ET today when two ships brokeaway from their moorings, and officials looked in a potential fuel oil spill, according to the US Coast Guard. The portion that closed provides access to Valero's 215,000 b/d Houston refinery, LyondellBasell's 264,000 b/d Houston refinery and Chevron's Pasadena refinery. Emissions filings with the Texas Commission on Environmental Quality (TCEQ) are yet to indicate the extent of any flaring and disruption to operations in the Houston area Thursday evening, but will likely be reported later Friday and over the weekend. Gulf coast refiners ran their plants at average utilization rates of 93pc in the week ended 10 May, according to the Energy Information Administration (EIA), up by two percentage points from the prior week as the industry heads into the late-May Memorial Day weekend and beginning of peak summer driving season. The next EIA data release on 22 May will likely reveal any dip in Gulf coast refinery throughputs resulting from the storm.

Brazil's Rio Grande do Sul reallocates gas supply
Brazil's Rio Grande do Sul reallocates gas supply
Sao Paulo, 17 May (Argus) — Natural gas supply in Brazil's Rio Grande do Sul had to be redistributed because of the historic floods in the state, with diesel potentially making its way back as an power plant fuel to leave more gas available for LPG production. Gasbol, the natural gas transportation pipeline that supplies Brazil's south, does not have capacity to meet demand from the 201,000 b/d Alberto Pasqualini refinery (Refap), state-controlled Petrobras' Canoas thermal power plant and natural gas distributors in the region, according to Petrobras' then-chief executive Jean Paul Prates said earlier this week. The Santa Catarina state gas distributor has adjusted its own local network to meet peak demand in neighboring Rio Grande do Sul via the pipeline transportation network. The Canoas thermal plant is running at its minimum generation at 150GW, with 61pc coming from its gas turbine. The plant was brought on line to reinstate proper power supply after transmission lines in the south were affected by the floods. Petrobras plans to use a diesel engine to increase power generation. The current approved fuel cost (CVU) for diesel in the Canoas plant is of R1,115.29/MWh. Petrobras is also operating Refap at 59pc of its maximum installed capacity, at 119,506 b/d. Heavy showers in Rio Grande do Sul since 29 April brought unprecedented flooding to the state, causing a humanitarian crisis and infrastructure damage. The extreme weather has left 154 people dead, 98 missing and over 540,000 people displaced, according to the state's civil defense.
