挪威Statfjord油田迄今累计产出51亿桶油当量

据海上石油新闻2019年11月25日挪威斯塔万格报道，挪威能源巨头Equinor日前隆重纪念了位于挪威北海的Statfjord巨型油气田40年的生产历史。

自1979年11月24日Statfjord油田 A平台投产以来，这个挪威最大海上油田迄今已累计产出51亿桶油当量的石油和天然气。

这个油田的开采寿命迄今已超过了预期，1999年曾一度讨论关闭Statfjord油田 A平台。

在20世纪，尽管Statfjord油田的石油储量巨大，但石油产量仍在迅速下降。Equinor表示，问题在于如何找到回报良好的钻井目标。

结果证明，解决产量下降的办法是生产更多的天然气和更少的石油。在Statfjord油田后期项目中，天然气产量增加了20%，油田生产寿命因此至少延长了10年。

1974年，美孚公司发现了Statfjord油田。Statfjord 油田B平台在1982年进入生产，18个月后C平台也投入生产。

North Sea Statfjord field enters fifth decade of production

Equinor has commemorated 40 years of production from the Statfjord oil and gas field in the Norwegian North Sea.

Since operations started through the Statfjord A platform on Nov. 24, 1979, the field has produced a cumulative 5.1 Bboe.

The lifespan has exceeded expectations, with discussions at one point of closing down Statfjord A in 1999.

During the 2000s, oil production was declining rapidly, despite large remaining reserves. The problem was finding drilling targets that provided good returns, Equinor said.

The solution turned out to be producing more gas and less oil. Under the Statfjord Late Phase project, gas production has risen by 20% and the field’s lifespan being extended by at least 10 years.

Mobil discovered Statfjord in 1974. Statfjord B entered service in 1982, followed 18 months later by the C platform.
