据世界天然气网8月30日消息 印度尼西亚石油和天然气监管机构SKK Migas已经批准了Tangguh液化天然气出口综合设施碳捕获利用和储存（CCUS）项目的开发计划。

SKK Migas为Ubadari油田和Vorwata CCUS的开发计划（POD）开绿灯。在该POD中，新开发项目估计从Ubadari和Vorwata油田可能额外回收1.3万亿立方英尺的天然气。

Ubadari油田将通过连接至Tangguh设施海上管道的正常无人装置（NUI）进行开采。同时，Vorwata CCUS开发将有约2500万吨二氧化碳注入Vorwata储层，以消除碳排放，并通过提高天然气回收率（EGR）增加天然气产量。

这将去除高达90%的储层相关二氧化碳。目前，这一二氧化碳排放量占Tangguh液化天然气排放量的近一半。

前端工程设计（FEED）将于2022年年中开始。预计项目将在2026年最终投资决策后开始。

CCUS project approved for Indonesia’s Tangguh LNG

Indonesian oil and gas regulator SKK Migas has approved the plan of development for a carbon capture utilisation and storage (CCUS) project at the Tangguh LNG export complex.

SKK Migas greenlighted the plan of development (POD) for Ubadari Field and Vorwata CCUS. In this POD, the new development estimated a potential additional recovery of 1.3 trillion cubic feet (Tcf) of gas, from both Ubadari and Vorwata fields.

Ubadari field will be produced via normally unmanned installations (NUI) connected to an offshore pipeline to the Tangguh facility. Meanwhile, the Vorwata CCUS development will see approximately 25 million tonnes of CO2 injected back to the Vorwata reservoir to eliminate carbon venting and provide incremental gas production through enhanced gas recovery (EGR).

This will remove up to 90 per cent of the reservoir-associated CO2. This CO2 is currently representing nearly half of the Tangguh LNG emissions.

The Front-End Engineering and Design (FEED) will start in mid-2022. An estimated project start is in 2026, after a final investment decision (FiD).
