挪威海Njord油田在中断六年后于12月27日恢复生产。

为 Equinor 运营的 Njord 油田提供服务的平台和 FSO 的升级已完成，该油田已恢复运行。 

Njord 气田的合作伙伴 Wintershall Dea 的首席运营官 Dawn Summers 表示：“今年结束时，没有比 Njord 气田重新生产更好的消息了。”

Aker Solutions 负责大部分平台工程和升级，而 Brevik Engineering 负责 Njord Bravo FSO 和 Aible FSO 升级的工程工作。

水深 330 m 的 Njord 油田于 1986 年被发现，于 1997 年开始生产石油，并于 2007 年开始天然气出口。预计油田寿命至 2013 年，但大量石油仍留在地下，而附近的发现如 Hyme，则与此相关。回到尼奥尔德，让油田的生产时间更长。

“这是第一次将平台和 FSO 与现场断开、升级并拖回，我们现在已将现场的寿命延长了一倍。” 这是一项艰巨且具有挑战性的工作，部分是在大流行期间完成的，”Equinor 负责项目、钻井和采购的执行副总裁 Geir Tungesvik 表示。“Njord 油田现在将在接下来的二十年里向市场提供重要的产量。” 

石油通过管道运输至 Njord Bravo FSO，然后通过油轮运往市场，而油田的天然气则通过与脜sgard 运输系统相连的 40 公里长管道输出，并从那里运至 K 块酶终端。

Njord Field 不断交付

经过 19 年的生产，该平台和 FSO 于 2016 年上岸。2017年和2018年，这两个装置获得了升级合同。Njord A 平台在 Stord 进行了升级，该平台建于 20 世纪 90 年代。Njord Bravo FSO 在升级前接受了检查，并准备在克里斯蒂安松拖走，而翻新工作则在海于格松进行。

据Equinor称，Njord油田的生产最初计划于2020年恢复，但升级项目比预期更具挑战性。该项目受到 COVID-19 大流行的严重打击，这也给成本带来了上行压力。最初，该项目预计耗资 170 亿挪威克朗（17 亿美元），但最终成本超过 310 亿挪威克朗（31.6 亿美元）。Equinor 表示，即便如此，即使价格比目前的价格“低得多”，该项目仍然有利可图。

Equinor 及其合作伙伴计划通过升级后的钻井设施在 Njord 钻 10 口新井。Njord外缘已有新发现，周边地区还将进行更多勘探。

Wintershall Dea Norge 董事总经理 Michael Zechner 表示：“Njord 油田的回归将释放周边水域的勘探潜力，并成为已发现的回接油田的中心。”

该平台和 FSO 升级使设施准备好接收两个新海底油田的生产，即 Equinor 运营的 Bauge 和 Neptune Energy 运营的 Fenja，这两个油田的可采资源量合计约为 110 MMboe。据 Neptune 称，Fenja 油田将于 2023 年开始生产。

Equinor 挪威勘探与生产执行副总裁 Kjetil Hove 表示：“我们的目标是从 Njord 和 Hyme 生产与我们迄今为止生产的石油当量相同的产量，即超过 2.5 亿桶石油当量。”

本月早些时候， Equinor 宣布计划通过 Draugen 平台利用岸上电力为Njord 油田提供部分电力。

Equinor 代表合作伙伴 Wintershall Dea Norge AS（持有 50%）和 Neptune Energy Norge AS（持有 22.5%）运营该油田，持有 27.5% 的权益。

Newly Upgraded Njord Field Back Online

Project complexity and the pandemic stretched the upgrade program for the Norwegian Sea field from four years to six.

After a six-year hiatus, the Njord Field in the Norwegian Sea resumed production on Dec. 27.

Upgrades of the platform and FSO serving the Equinor-operated Njord Field are complete and the field is back onstream. 

“I could not have asked for better news to close out the year than the Njord gas field restarting production,” said Dawn Summers, the COO for Wintershall Dea, a partner in the Njord Field.

Aker Solutions carried out much of the platform engineering and upgrades, while Brevik Engineering handled the engineering work for the Njord Bravo FSO and Aible the FSO upgrades.

The Njord Field in 330 m water depth was discovered in 1986, began producing oil in 1997, with gas exports starting in 2007. The projected field life was through 2013, but large volumes remaining in the ground and nearby discoveries like Hyme, which was tied back to Njord, kept the field producing longer.

“This is the first time a platform and FSO have been disconnected from the field, upgraded, and towed back, and we have now doubled the field’s life. It has been a big and challenging job, partly performed during a pandemic,” Geir Tungesvik, Equinor's executive vice president for Projects, Drilling & Procurement, said. “The Njord Field will now deliver important volumes to the market for another two decades." 

The oil is transported by pipeline to the Njord Bravo FSO and onwards by tankers to the market, while gas from the field is exported through a 40-km pipeline connected to the Åsgard transportation system, and from there to the Kårstø terminal.

Njord Field keeps delivering

The platform and FSO were brought ashore in 2016 after 19 years of production. In 2017 and 2018, upgrading contracts were awarded for the two installations. The Njord A platform was upgraded at Stord, where it was constructed in the 90s. The Njord Bravo FSO was inspected prior to upgrade and prepared for tow-out in Kristiansund, whereas the refurbishment was carried out in Haugesund.

According to Equinor, production from the Njord Field was initially slated to resume in 2020, but the upgrade project was more challenging than expected. The project was hard hit by the COVID-19 pandemic, which also put an upward pressure on costs. Originally, the project was expected to cost NOK 17 billion (US$1.7 billion), but it topped out at over NOK 31 billion (US$3.16 billion). Even so, Equinor said, the project remains profitable even if prices drop “far lower” than current rates.

Equinor and its partners plan to drill 10 new wells at Njord from an upgraded drilling facility. New discoveries have been made at the outer edges of Njord, and more exploration will be carried out in the surrounding area.

“The return of the Njord Field will unlock potential for exploration in the surrounding waters, as well as a hub for tie-back fields already discovered,” said Michael Zechner, managing director of Wintershall Dea Norge.

The platform and FSO upgrades made the facilities ready to receive production from two new subsea fields, the Equinor-operated Bauge and Neptune Energy-operated Fenja, which together hold recoverable resources of about 110 MMboe. According to Neptune, the Fenja Field will begin production in 2023.

“Our ambition is to produce about the same volume from Njord and Hyme as we have produced so far, more than 250 million barrels of oil equivalent," Kjetil Hove, Equinor's executive vice president for Exploration & Production Norway, said.

Earlier this month, Equinor announced plans to partially electrify the Njord Field with power from shore via the Draugen platform.

Equinor operates the field with 27.5% interest on behalf of partners Wintershall Dea Norge AS with 50% and Neptune Energy Norge AS with 22.5%.
