据11月8日离岸能源网站报道，澳大利亚伍德赛德（Woodside）石油天然气公司已经完成了斯卡伯勒天然气田的地下勘探研究，使其资源量增加了52%。
伍德赛德表示，斯卡伯勒气田预测表外资源总量(2C)增至11.1万亿立方英尺，较此前估计的7.3万亿立方英尺增加了52%。
该公司在斯卡伯勒地区的权益，包括斯卡伯勒，Thebe，和Jupiter油田，其中包括对WA-1-R（包含斯卡伯勒油田的大部分）的75%的权益，以及对WA-61-R、WA-62-R和WA-63-R各50%的权益。
值得注意的是，伍德赛德是这些保留租赁的经营者。由于产量的增加，斯卡伯勒地区估计的干气表外资源总量(2C)为13万亿立方英尺，比之前的9.2万亿立方英尺增加了41%。
伍德赛德补充道，综合地下研究包括全波形反演、三维地震再处理和更新的岩石物理解释。地震勘探资料叠后处理提高了储层成像质量，增加了储层砂层分布信息。
此外，对电缆测井数据和特殊岩心分析的测量数据进行全面综合的审查也增加了净砂比例和气体饱和度。据伍德赛德表示，这项工作是由外部独立的储量审计员提供的。
值得注意的是，伍德赛德的企业表外资源总量(2C)增加了5.03亿，达到60.2亿桶。
伍德赛德首席执行官彼得·科尔曼表示:“自从40年前发现斯卡伯勒气田以来，我们将前沿技术应用到收集的地球物理数据中，提高了我们对该气田价值的估计。通过释放斯卡伯勒天然气资源的巨大潜力，我们加强了开发该地区的理由，并将斯卡伯勒的预期现金流延长了数年。这一资源升级进一步完善了斯卡伯勒现有的价值主张，我们的目标是在2024年交付一个新的、具有全球竞争力的液化天然气项目。”

Woodside increases gas estimate for Scarborough project
Australian oil and gas company Woodside has completed subsurface studies Woodside said The company’s interest in the Greater Scarborough area, which covers the Scarborough, Thebe, and Jupiter fields, comprises a 75 percent interest in WA-1-R – which contains the majority of the Scarborough field – and a 50 percent interest in each of WA-61-R, WA-62-R, and WA-63-R.
It is worth noting that Woodside is the operator of these retention leases.
As a result of the volume increase, Greater Scarborough contains an estimated gross dry gas contingent resource (2C) volume of 13.0 tcf, a 41 percent increase from the previous 9.2 tcf.
Woodside added that the integrated subsurface studies incorporated full-waveform inversion 3D seismic reprocessing and updated petrophysical interpretation.
The seismic reprocessing improved the reservoir imaging quality and increased reservoir sand distribution.
Also, a comprehensive integrated review of the wireline log data and measurements from special core analysis increased net sand proportion and gas saturations. According to Woodside, assurance of this work was provided by an external independent reserves auditor.
It is worth noting that Woodside’s overall corporate contingent resources (2C) increased by 503 mmboe to 6,020 mmboe.
Woodside CEO Peter Coleman said: “Our understanding of the value of the Scarborough gas resource has increased after applying leading-edge technology to geophysical data collected since the field’s discovery almost 40 years ago.
“By unlocking the huge potential of the Scarborough gas resource we’ve strengthened the case for the development and extended the expected cashflow from Scarborough for years. This resource upgrade further improves Scarborough’s existing value proposition as we target the delivery of a new, globally competitive LNG project from 2024.”
