- <p class=MsoBodyText><span lang=EN-GB>Well 10/4.-1 was drilled to test the Zeppelin
- prospect ca 35 km southeast of the Yme Field in the North Sea. The primary
- objective was to evaluate the presence of hydrocarbons in sandstones of the Jurassic
- Sandnes and Bryne formations. Secondary target were the Zechstein Group
- limestones of Late Permian age.</span></p>
- <p class=MsoBodyText><b><span lang=EN-GB>Operations and results</span></b></p>
- <p class=MsoBodyText><span lang=EN-GB>Wildcat well 10/4-1 was spudded with the semi-submersible
- installation Borgland Dolphin on 20 June 2015 and drilled to TD at 2415 m in
- the Permian Zechstein Group. No significant problem was encountered in the
- operations. The well was drilled with seawater and hi-vis pills down to 640 m
- and with Innovert oil based mud from 640 m to TD. </span></p>
- <p class=MsoBodyText><span lang=EN-GB>Top Sandnes Formation was encountered at
- 2274 m and top Bryne Formation at 2311 m.</span></p>
- <p class=MsoBodyText><span lang=EN-GB>Both formation had sandstones with very
- good reservoir quality. The Sandnes reservoir has an average porosity of 21.5
- %, and the Bryne Formation 17.4 %, using a cut off value of 10%. The gross
- thickness for the Sandnes Formation is 21 m with a net thickness of 19.15 m. The
- well encountered the Bryne reservoir with a gross thickness of 53 m and net
- thickness of 38.75 m. The water saturation is 100 % in both encountered
- reservoirs. The expected Permian age limestone reservoir was not present at this
- well location. All reservoirs were water-wet. The well also encountered sandstone
- of undifferentiated Triassic age with good quality. The sandstone of 16 m gross
- and 15.95 m net thickness had an average porosity of 23.7 %. It is water-wet. No
- shows were observed in the well</span></p>
- <p class=MsoBodyText><span lang=EN-GB>No cores were cut. No fluid sample was
- taken.</span></p>
- <p class=MsoBodyText><span lang=EN-GB>The well was permanently abandoned on 12
- July 2015 as a dry well.</span></p>
- <p class=MsoBodyText><b><span lang=EN-GB>Testing</span></b><span lang=EN-GB> </span></p>
- <p class=MsoBodyText><span lang=EN-GB>No drill stem test was performed. </span></p>
