据OE网站3月26日报道,瑞典石油公司伦丁能源(Lundin Energy)在挪威近海的北海发现石油。
据挪威石油总监(NPD)周五表示,伦丁的挪威子公司Lundin Energy Norge已经完成了16/4-13 S探井的钻探工作。
该井位于北海中部Edvard Grieg油田以南约15公里,Stavanger以西190公里处,使用west Bollsta半潜式钻机钻探的。
据NPD称,这口井的目的是探明三叠纪至古生代储集岩中的石油。这口井在这些岩石的砾岩砂岩中遇到了10米的油柱,其中大约7米的储层质量中等到较差。在海面下1950米处发现了油/水接触点。整个油藏,包括水域,由砾岩砂岩组成,厚度约380米。据初步估计,这一发现的可采石油当量在50万-140万标准立方米之间。许可方将评估这一发现是否与Solveig油田有关联。
这是359号生产许可区的第六口勘探井。该许可证是在2005年APA颁发的。
该井钻井至海平面以下2,422米的测量深度和2,325米的垂直深度,并终止于古生代岩石中。现场水深100米。这口井将被永久封堵并废弃。
West Bollsta将在北海359号生产许可区的Solveig油田钻探16/4-BA-1H生产井,Lundin Energy Norway AS是该油田的运营商。

Lundin Makes Minor Oil Find Off Norway. Eyes Tie-in to Solveig Field
Swedish oil company Lundin Energy has made a minor oil discovery in the North Sea, offshore Norway.
The Norwegian Petroleum Director said Friday that Lundin's Norwegian subsidiary Lundin Energy Norge had completed the drilling of the wildcat well 16/4-13 S.
The well was drilled about 15 kilometers south of the Edvard Grieg field in the central part of the North Sea and 190 kilometers west of Stavanger, using the West Bollsta semi-submersible drilling rig.
"The objective of the well was to prove petroleum in reservoir rocks from the Triassic to Paleozoic Age. The well encountered an oil column of 10 meters in conglomerate sandstone in these rocks, about 7 meters of which with moderate to poor reservoir quality," the NPD said.
The oil/water contact was encountered 1950 meters below the sea surface. The entire reservoir, including the water zone, consists of conglomeratic sandstones and in a thickness of about 380 meters.
"Preliminary estimates place the size of the discovery between 0.5 and 1.4 million standard cubic meters (Sm3) of recoverable oil equivalent. The licensees will assess the discovery with regard to a possible tie-in to the Solveig field," the NPD said.
This is the sixth exploration well to be drilled in production licence 359. The licence was awarded in APA 2005.
The well was drilled to respective measured and vertical depths of 2,422 and 2,325 meters below sea level and was terminated in Paleozoic rocks. The water depth at the site is 100 meters. The well will be permanently plugged and abandoned.
The West Bollsta will now move to drill the production well 16/4-BA-1H on the Solveig field in production licence 359 in the North Sea, where Lundin Energy Norway AS is the operator.
