據(jù)OE網(wǎng)站8月10日?qǐng)?bào)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(kāi)始在其羅爾夫斯內(nèi)斯(Rolvsnes )近海油田的延長(zhǎng)井測(cè)試(EWT)中生產(chǎn)，這是Edvard Grieg平臺(tái)的第一個(gè)水下回接開(kāi)發(fā)項(xiàng)目。
Rolvsnes油田位于Edvard Grieg油田南側(cè)的生產(chǎn)許可區(qū)，是一個(gè)風(fēng)化破碎的花崗巖基底油藏。
2018年，一口水平評(píng)價(jià)井(16/1-28)的鉆探和測(cè)試完成，產(chǎn)量為7000桶/天，證明了良好的儲(chǔ)層產(chǎn)能。
倫丁表示，該評(píng)價(jià)井已經(jīng)轉(zhuǎn)化為開(kāi)發(fā)井，并與3公里處的Edvard Grieg平臺(tái)連接，該項(xiàng)目在預(yù)算成本估算的基礎(chǔ)上按期完成。
Rolvsnes油田的資源估計(jì)在1400萬(wàn)—7800萬(wàn)桶油當(dāng)量之間。
2022年底完成整個(gè)油田開(kāi)發(fā)計(jì)劃
倫丁稱，EWT的目標(biāo)是更好地了解儲(chǔ)層性質(zhì)、儲(chǔ)層連通性和該油田的長(zhǎng)期生產(chǎn)動(dòng)態(tài)，如果成功，該測(cè)試有可能開(kāi)啟Rolvsnes油田的全面開(kāi)發(fā)，進(jìn)一步延長(zhǎng)Edvard Grieg的穩(wěn)產(chǎn)期。
一旦收集到足夠的數(shù)據(jù)和生產(chǎn)經(jīng)驗(yàn)，就可以在2022年底提交開(kāi)發(fā)和運(yùn)營(yíng)計(jì)劃(PDO)，這將受益于挪威的臨時(shí)稅收制度。在Utsira High的風(fēng)化破碎花崗巖基底油藏中，成功的測(cè)試還可能帶來(lái)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(yùn)營(yíng)商，擁有80%的開(kāi)采權(quán)益，其余權(quán)益由OMV (Norge) AS持有。
倫丁能源總裁兼首席執(zhí)行官Nick Walker評(píng)論道，我們的戰(zhàn)略重點(diǎn)之一是延長(zhǎng)Edvard Grieg的穩(wěn)定生產(chǎn)，長(zhǎng)期保持設(shè)施充足。通過(guò)成功釋放Edvard Grieg油田內(nèi)的資源和附近油田回接開(kāi)發(fā)，我們已經(jīng)成功地將Edvard Grieg穩(wěn)產(chǎn)延長(zhǎng)了5年以上。Rolvsnes EWT是第一個(gè)回接到我們運(yùn)營(yíng)的Edvard Grieg樞紐中心的開(kāi)發(fā)項(xiàng)目，來(lái)自EWT的生產(chǎn)數(shù)據(jù)將為Rolvsnes油田的全面開(kāi)發(fā)提供重要信息，以及Utsira High地區(qū)進(jìn)一步風(fēng)化基底儲(chǔ)層的機(jī)會(huì)。

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.”
