摘要

Tunu是印度尼西亚最大的天然气田之一,面积为1400平方公里,位于东加里曼丹的Mahakam三角洲。该油田自1990年以来一直在生产,到2020年底,从1000多口作业井中累计产量超过9.5万亿立方英尺,凝析油产量为190万桶。如今,Tunu油田约占Mahakam产量的40%。经过30年的生产,Tunu的生产水平目前处于下降阶段,其年产量曲线从2008年开始呈现下降趋势。此外,Tunu井开发项目由于单井储量的消耗而被认为是边际经济的。因此,为了降低Tunu管道在当前运行参数下的地面支出成本,进行了综合研究。该研究包括WHSIP历史匹配,以确定新的管道设计压力,评估未来油井的生产寿命,并根据Tunu油田观察到的实际腐蚀速率调整管道腐蚀余量。结果表明,未来大多数Tunu井的WHSIP预计在200磅以下,生产寿命为1.5至3年。通过对注入缓蚀剂的管道进行腐蚀检测,发现Tunu油田的腐蚀速率小于1 mm/20年。因此,Tunu管道的腐蚀余量从5毫米优化到3毫米,设计寿命为10年。对于特殊情况,如实际井的WHSIP > 200 bar,则采用其他生产方法。因此,通过将最近的地下行为(WHSIP和井寿命)与地面了解(腐蚀速率)相结合,为Tunu开发提出了新的管道设计。这项研究为2020年的管道采购节省了1300万美元的成本。此外,新管道设计的实施为未来的管道采购减少了40%的管道单位成本。该研究已成为Tunu油田未来油井开发项目的基础,大大延长了Mahakam油田的生产可持续性。

Unlocking Marginal Resources through Synergy between Subsurface and Surface Entities
Tunu is one of the biggest gas fields in Indonesia with 1400 km2 area in Mahakam Delta, East Kalimantan. This field has been producing since 1990 with cumulative production of more than 9.5 tcf and 190 mbbl condensate by the end of 2020 from over 1000 operating wells. Today, Tunu field contributes for approximately 40% of Mahakam production. After 30 years of production, Tunu production level is currently in declining phase, shown by its yearly production profile which exhibits a declining trend since 2008. Furthermore, Tunu well development project was considered marginally economical due to depleting reserve per well. Thus, an integrated study was conducted in order to reduce surface expenditure cost of Tunu pipeline based on current operating parameters. The study consisted of WHSIP history matching to determine new pipeline design pressure, evaluation of future wells production lifetime, and adjustment of pipeline corrosion allowance based on actual corrosion rate observed in Tunu field. Results show that most of future Tunu wells are predicted to have WHSIP below 200 barg and 1.5 to 3 years’ production lifetime. Corrosion rate in Tunu field as measured using corrosion coupon in piping with corrosion inhibitor injection is found to be less than 1 mm/20 years. Therefore, corrosion allowance for Tunu pipeline is optimized from 5 to 3 mm for 10-years design lifetime. For exceptional circumstances where actual well WHSIP > 200 barg, other method of producing the well will be implemented. Hence, by integrating recent subsurface behavior (WHSIP and well lifetime) with surface understanding (corrosion rate), it was then proposed new pipeline design for Tunu development. This study has generated USD 13 million cost saving for pipeline procurement in 2020. Moreover, implementation of the new pipeline design reduces 40% of pipeline unit cost for future pipeline procurement. This study has become the basis for future well development projects in Tunu field which significantly prolong Mahakam's production sustainability.
