据OE网站8月10日报道，专注于挪威大陆架的瑞典石油公司伦丁能源公司(Lundin Energy )周二表示，其已开始在其罗尔夫斯内斯(Rolvsnes )近海油田的延长井测试(EWT)中生产，这是Edvard Grieg平台的第一个水下回接开发项目。
Rolvsnes油田位于Edvard Grieg油田南侧的生产许可区，是一个风化破碎的花岗岩基底油藏。
2018年，一口水平评价井(16/1-28)的钻探和测试完成，产量为7000桶/天，证明了良好的储层产能。
伦丁表示，该评价井已经转化为开发井，并与3公里处的Edvard Grieg平台连接，该项目在预算成本估算的基础上按期完成。
Rolvsnes油田的资源估计在1400万—7800万桶油当量之间。
2022年底完成整个油田开发计划
伦丁称，EWT的目标是更好地了解储层性质、储层连通性和该油田的长期生产动态，如果成功，该测试有可能开启Rolvsnes油田的全面开发，进一步延长Edvard Grieg的稳产期。
一旦收集到足够的数据和生产经验，就可以在2022年底提交开发和运营计划(PDO)，这将受益于挪威的临时税收制度。在Utsira High的风化破碎花岗岩基底油藏中，成功的测试还可能带来巨大的额外资源潜力。
伦丁能源挪威公司(Lundin Energy Norway AS)是伦丁能源的子公司，是PL338C许可区的运营商，拥有80%的开采权益，其余权益由OMV (Norge) AS持有。
伦丁能源总裁兼首席执行官Nick Walker评论道，我们的战略重点之一是延长Edvard Grieg的稳定生产，长期保持设施充足。通过成功释放Edvard Grieg油田内的资源和附近油田回接开发，我们已经成功地将Edvard Grieg稳产延长了5年以上。Rolvsnes EWT是第一个回接到我们运营的Edvard Grieg枢纽中心的开发项目，来自EWT的生产数据将为Rolvsnes油田的全面开发提供重要信息，以及Utsira High地区进一步风化基底储层的机会。

Edvard Grieg Tie-Back: Lundin Starts Production From Rolvsnes Offshore Field
Lundin Energy, a Swedish oil firm focused on the Norwegian Continental Shelf, on Tuesday said it had started production from the Extended Well Test (EWT) at its Rolvsnes offshore field, the first subsea tie back development for the Edvard Grieg platform.
The Rolvsnes field is located in a production license on the southern side of the Edvard Grieg field and is a weathered and fractured granite basement reservoir.
During 2018, the drilling and testing of a horizontal appraisal well (16/1-28) was completed, which flowed 7,000 bopd, demonstrating good reservoir productivity.
"The appraisal well has been converted to a development well and tied back the 3 km distance to the Edvard Grieg platform, with the project being completed on schedule and on the budget cost estimate," Lundin said.
The resource estimate for the Rolvsnes field is between 14 and 78 million barrels of oil equivalent (MMboe) gross.
Full field development plan by 2022 end
"The objective of the EWT is to gain a better understanding of the reservoir properties, reservoir connectivity and long term production performance of the field and if successful, this test has the potential to unlock a full field development for Rolvsnes, further extending the plateau production period for Edvard Grieg," Lundin said.
once sufficient data and production experience has been gathered, a Plan for Development and Operation (PDO) could be submitted by the end of 2022, benefitting from the temporary tax regime in Norway. A successful test could also derisk significant additional resource potential in weathered and fractured granite basement reservoirs on the Utsira High.
Lundin Energy Norway AS, a subsidiary of Lundin Energy, is the operator of the license PL338C with an 80 percent working interest, with the remaining interest held by OMV (Norge) AS.
Nick Walker, President and CEO of Lundin Energy, commented: "One of our strategic priorities is to extend plateau production on Edvard Grieg keeping the facilities full in the long term. We have successfully managed to extend the Edvard Grieg plateau by over 5 years already, through successfully unlocking resources within the Edvard Grieg field and through near field tie-back developments.
"The Rolvsnes EWT is the first tie-back development into our operated Edvard Grieg hub and production data from the EWT will provide vital information to potentially unlock the full field development of the Rolvsnes field, as well as further weathered and fractured basement reservoir opportunities on the Utsira High.”
