General
Well 2/7-21 SR is a re-entry of well 2/7-21 S, which tested oil and gas in undefined pre-Cretaceous rocks of the Embla Field. The gas produced unexpectedly contained up to 40 ppm H2S in addition to ca 5% CO2. The purpose of the re-entry was further testing
Operations and results
Well 2/7-21 SR was re-entered with the semi-submersible installation West Delta on 13 September 1991.
The reservoir pressure and H2S content was tested.
The well was completed on 14 October 1991 and reclassified to development well 2/7-D-21.
Testing
No drill stem test was performed.
No cuttings in this wellbore.
No cores in this wellbore.
No scanned core photos available
No palynological slides in this wellbore.
No oil samples available.
