Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
General
Well 15/5-2 R is a re-entry of well 15/5-2 in the Ve Sub-basin in the North Sea, north of the Sleipner Vest Field and 15/5-1 Gina Krog Discovery. Well 15/5-2 found gas in Jurassic and Triassic sandstones and was suspended without testing. The objective of the re-entry was to conduct a production test from the Triassic reservoir.
Operations and results
Well 15/5-2 was re-entered with the semi-submersible installation Treasure Seeker on 2 November 1979.
After testing, the well was plugged and permanently abandoned on 7 December 1979.
Testing
Two FIT runs at 4150 m were attempted in order to obtain fluid samples. Both runs failed.
A production test was run in the Triassic Hegre Group over the perforated intervals 4142 - 4146 and 4148 -4152 m. The test produced 304120 Sm3 gas and 17.6 Sm3 liquid hydrocarbons /day through a 48/64” choke. The gas/condensate ratio was 17260 Sm3/Sm3, the condensate gravity was 49 °API, and the gas gravity was 0.622 (air = 1). The reservoir temperature estimated from the test is 130.6 °C (267 °F).

About this data
Norwegian Offshore Directorate (Sodir) FactPages, mirrored nightly and used under the Norwegian Licence for Open Government Data (NLOD). Depths are metres along the wellbore from the kelly bushing unless a row gives its own unit; older cores are filed in feet. A zero the Directorate files for an unmeasured pressure, density, or temperature is shown as a dash.
