It is located just north of\r\nStatfjord East and south of Statfjord North in the southern part of License PL\r\n172 updip from the 33/9-15 well and within the same seismically defined Intra\r\nDraupne deposits of Volgian age. The primary objective was to evaluate the\r\nhydrocarbon potential of the Late Jurassic (Volgian) Intra-Draupne Formation\r\nsandstone ("Munin sandstone unit") above the oil/water contact (2719\r\nm subsea), found in the 33/9-15 well. The secondary objective was to evaluate\r\nthe Middle Jurassic sands of the Brent Group.\u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cb\u003e\u003cspan lang=EN-GB\u003eOperations and results\u003c/span\u003e\u003c/b\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eWell 33/9-16 was spudded with the\r\nsemi-submersible installation "Ross Isle" on 28 November 1992 and\r\ndrilled to TD at 2870 m in the Middle Jurassic Ness Formation.

A\r\n4.3 m zone with oil shows was encountered in the uppermost part of this unit\r\nbased on shows while drilling and MWD. Three cores were cut in the Draupne\r\nFormation. Except for the top meter, the entire Intra Draupne sandstone unit\r\nwas cored. The top 4 m of the core consisted of a sandstone with good porosity\r\nand oil shows. \u003c/span\u003e\u003c/p\u003e\r\n\r\n\u003cp class=MsoBodyText\u003e\u003cspan lang=EN-GB\u003eIn the Middle Jurassic Brent Group, no\r\noil shows were observed in sandstones of the Tarbert and Ness Formations and as\r\na result no cores were cut.
