Equinor在北海古德龙油田附近发现石油

中国石化新闻网讯 据离岸能源3月2日消息称，Equinor于2019年11月获得了北海两口井的钻井许可证。这些井位于025号生产许可证中，Equinor是运营商。

这些井位于古德龙东南约11公里处、15/3-4 (Sigrun)油气发现井东南约4公里处、斯塔万格以西220公里处。这些油井由Equinor和Neptune能源挪威公司作为唯一的风险井进行钻探。

15/3-12 S井的主要和次要勘探目标分别是在中、上侏罗统储层(Hugin地层和Draupne地层)中探明石油。

该井在Hugin地层分别遇到了9米、4米和9米三个不同的注油层，厚度约为100米。储藏区主要为中等质量储层。没有遇到油水接触点。

探井15/3- 12a的勘探目标是在上侏罗统储层和中侏罗统储层(Draupne地层和Hugin地层)中探明石油。

初步估计发现的石油储量在100万至270万标准立方米(Sm3)之间。将考虑将这一发现与古德龙油田联系起来进行开发。

虽然没有进行地层测试，但是已经收集了大量的数据和样品。

15/3-12 S井和15/3-12 A井分别钻至海平面以下垂直深度为3652米和3796米，实测深度分别为3771米和3999米处。

Equinor strikes oil near Gudrun field in North Sea

Equinor received drilling permits for the two North Sea wells in November 2019. The wells are located in production license 025 where Equinor is the operator.

The wells were drilled about 11 kilometers southeast of Gudrun, 4 kilometers southeast of the 15/3-4 (Sigrun) oil and gas discovery and 220 kilometers west of Stavanger. The wells were drilled as sole risk wells by Equinor and Neptune Energy Norge.

The primary and secondary exploration targets for wildcat well 15/3-12 S were to prove petroleum in Middle and Upper Jurassic reservoir rocks (the Hugin and Draupne Formations), respectively.

The well encountered three separate oil-filled reservoir zones of 9, 4 and 9 meters in the Hugin Formation, which are about 100 meters thick. The reservoir zones mainly have moderate reservoir quality. The oil/water contacts were not encountered.

The exploration target for wildcat well 15/3-12 A was to prove petroleum in Upper and Middle Jurassic reservoir rocks (the Draupne and Hugin Formations), respectively.

Preliminary estimates place the size of the oil discovery between 1.0 and 2.7 million standard cubic meters (Sm3) of recoverable oil. The development of the discovery as a tie-in to the Gudrun field will be considered.

No formation tests were performed, but extensive volumes of data have been collected and samples have been taken.

The wells 15/3-12 S and 15/3-12 A were drilled to respective vertical depths of 3652 and 3796 meters below sea level, and respective measured depths of 3771 and 3999 meters below sea level.
