印度尼西亚批准 Rokan 区块开发计划

印度尼西亚已批准 Rokan 区块的开发计划,其中涉及通过用蒸汽置换石油来提高石油采收率。 路透社对此进行了报道。

让我们回顾一下,蒸汽驱油是一种提高地层采收率 (EOR) 的方法,在驱替高粘度油时最常见。 投资额为3.7万亿卢比(2.3871亿美元)。

Rokan区块是印度尼西亚最大的石油和天然气区块之一,包含几个主要油田,包括Duri、Minas、Bekasap和Kotabatak,以及许多较小的油田。 该区块于 1951 年开始采矿。

自2021年8月起,该区块由印度尼西亚国有公司Pertamina运营。 根据生产共享协议(PSA),Pertamina 将继续在该区块生产直至 2041 年。 在 20 年合同期限内,该公司在 Rokan 的资本支出将约为 700 亿美元。

Pertamina 从该国政府获得了运营商权利。 直到2021年,该运营商都是美国雪佛龙公司的子公司——PT Chevron Pacific Indonesia (PT CPI),但合同已经到期。 据报道,雪佛龙将合同延长到 2021 年以后的报价远低于 Pertamin 的报价。 Pertamina 计划从雪佛龙之前未关注的油田开始开发该区块。

Indonesia Approves Rokan Block Development Plan

Indonesia has approved a development plan for the Rokan block, which involves increasing oil recovery by displacing oil with steam. Reuters reports this.

Let us recall that steam displacement of oil is a method of enhanced oil recovery (EOR) of formations, the most common when displacing high-viscosity oil. The volume of investment is 3.7 trillion rupees (238.71 million US dollars).

The Rokan Block is one of Indonesia’s largest oil and gas blocks, and contains several major fields, including Duri, Minas, Bekasap and Kotabatak, as well as many smaller ones. Mining at the block began in 1951.

Since August 2021, the block has been operated by the Indonesian state-owned company Pertamina. Under the production sharing agreement (PSA), Pertamina will continue production at the block until 2041. Over the 20-year term of the contract, the company’s capital expenditures on Rokan will be approximately $70 billion.

Pertamina received operator rights from the government of the country. Until 2021, the operator was a subsidiary of the American Chevron – PT Chevron Pacific Indonesia (PT CPI), but the contract has expired. Chevron’s offer to extend the contract beyond 2021 was reported to be much lower than Pertamin’s offer. Pertamina planned to start developing the block from fields that Chevron had not previously focused on.
