Well history
WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE
Well 35/2-1 R is a re-entry of well 35/2-1 on the Tampen Spur about one block west of the Agat discovery in the northern North Sea. The 35/2-1 well was a dry gas discovery in the Pleistocene Peon sandstone member of the Nordand Group. Top Peon sandstone member was at 574 m (165 m below sea floor). The objective of the re-entry was testing and permanent abandonment.
Operations and results
Well 35/2-1 was re-entered (35/2-1 R) with the semi-submersible installation Deepsea Trym 15 June 2006. Upon re-entering the well it was discovered that some gas bubbles were leaking up to the surface around the conductor. The DVD recordings from the ROV showed that the gas flow was very low. Based on the short distance from the reservoir and the poor cement bonding detected behind the casings, decision was made to halt the operation and not perform the planned Drill Stem Test operation.
The reservoir temperature at 574 m was estimated between the MDT measurement (35/21) of 14.3 deg C and the EMS measurement (35/21 R) of 16.8 deg C. The MDT reading could have been influenced by gas cooling and the EMS reading could have been influenced by the heating effect as a result of about 9 hours spent drilling out cement and cleaning the hole in and below the reservoir section.
No cores were cut and no fluid samples were taken.
The well was permanently abandoned on 25 July 2006.
Testing
No drill stem test was performed.

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.
