石油圈中國石化新聞網訊 據彭博社4月9日斯德哥爾摩報道，倫丁石油公司(Lundin Petroleum AB)宣布，其全資子公司倫丁挪威公司已開始在巴倫支海(Barents Sea)南部的PL609的阿爾塔發現鉆探鉆井 7220/11-5。 鉆井完成后，該口井將用于延長井測試。 阿爾塔發現位于巴倫支海南部的PL609，距挪威海岸線約160千米。 這一發現是在2014年完成的，目前已經完成了3個成功的評價井。 位于PL492的鄰近的Gohta發現與更大的Alta發現一起被認為是一種可能的聯合開發機會。 據估計，阿爾塔和Gohta發現的總資源儲量范圍在11500到39000萬桶標油之間。 在油區將鉆探一口700米長的水平井，這將提高二疊紀-三疊紀巖溶性和裂縫性碳酸鹽巖儲層的橫向地質認識。 延長井測試的主要目標是證明可持續生產率，并減少該儲層恢復機制周圍的不確定性，為進一步開發研究打下基礎。 半潛式鉆機Leiv Eiriksson將用于阿爾塔發現的鉆井和測試。 該口井將通過鉆機進行大約兩個月的測試，產出的量將通過一條撓性出油管流入油輪。 擴展井測試的成功結果將為進一步評估鉆井和現場開發活動提供重要的信息。 鉆探和測試預計需要140天。 挪威倫丁公司是PL609的作業者，擁有40%的工作權益。 合作伙伴為DEA Norge AS和Idemitsu Petroleum Norge AS，各擁有30%的工作權益。 蔡小全 編譯自 彭博社 原文如下： Lundin Norway begins drilling for extended well testing of Alta discovery Lundin Petroleum AB has announced that its wholly owned subsidiary Lundin Norway AS has commenced drilling well 7220/11-5 on the Alta discovery in PL609 in the southern Barents Sea. Following drilling, the well will be used for extended well testing. The Alta discovery is located in PL609 in the southern Barents Sea, approximately 160 km from the Norwegian coastline. The discovery was made in 2014 and three successful appraisal wells have been completed to date. The adjacent Gohta discovery located in PL492 is considered a possible joint development opportunity together with the larger Alta discovery. The combined gross contingent resource range for the Alta and Gohta discoveries is estimated to between 115 and 390 MMboe. A 700-m long horizontal well will be drilled in the oil zone, which will improve the lateral geological understanding of the Permian-Triassic karstified and fractured carbonate reservoirs. The main objectives of the extended well test is to prove sustainable production rates and reduce the uncertainty around the recovery mechanism in this reservoir to provide the basis to progress development studies. The semisubmersible drilling rig Leiv Eiriksson will be used for the drilling and testing at Alta. The well will be tested through the rig for about two months and the produced volumes will be flowed via a flexible flowline to a tanker. Drilling and testing is expected to take 140 days. Lundin Norway is the operator of PL609 with a 40% working interest. The partners are DEA Norge AS and Idemitsu Petroleum Norge AS with 30% working interest each.
