據OE網站8月10日報道，專注于挪威大陸架的瑞典石油公司倫丁能源公司(Lundin Energy )周二表示，其已開始在其羅爾夫斯內斯(Rolvsnes )近海油田的延長井測試(EWT)中生產，這是Edvard Grieg平臺的第一個水下回接開發(fā)項目。

　　Rolvsnes油田位于Edvard Grieg油田南側的生產許可區(qū)，是一個風化破碎的花崗巖基底油藏。

　　2018年，一口水平評價井(16/1-28)的鉆探和測試完成，產量為7000桶/天，證明了良好的儲層產能。

　　倫丁表示，該評價井已經轉化為開發(fā)井，并與3公里處的Edvard Grieg平臺連接，該項目在預算成本估算的基礎上按期完成。

　　Rolvsnes油田的資源估計在1400萬—7800萬桶油當量之間。

　　2022年底完成整個油田開發(fā)計劃

　　倫丁稱，EWT的目標是更好地了解儲層性質、儲層連通性和該油田的長期生產動態(tài)，如果成功，該測試有可能開啟Rolvsnes油田的全面開發(fā)，進一步延長Edvard Grieg的穩(wěn)產期。

　　一旦收集到足夠的數據和生產經驗，就可以在2022年底提交開發(fā)和運營計劃(PDO)，這將受益于挪威的臨時稅收制度。在Utsira High的風化破碎花崗巖基底油藏中，成功的測試還可能帶來巨大的額外資源潛力。

　　倫丁能源挪威公司(Lundin Energy Norway AS)是倫丁能源的子公司，是PL338C許可區(qū)的運營商，擁有80%的開采權益，其余權益由OMV (Norge) AS持有。

　　倫丁能源總裁兼首席執(zhí)行官Nick Walker評論道，我們的戰(zhàn)略重點之一是延長Edvard Grieg的穩(wěn)定生產，長期保持設施充足。通過成功釋放Edvard Grieg油田內的資源和附近油田回接開發(fā)，我們已經成功地將Edvard Grieg穩(wěn)產延長了5年以上。Rolvsnes EWT是第一個回接到我們運營的Edvard Grieg樞紐中心的開發(fā)項目，來自EWT的生產數據將為Rolvsnes油田的全面開發(fā)提供重要信息，以及Utsira High地區(qū)進一步風化基底儲層的機會。

　　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.”
