Well history

WRITTEN BY THE NORWEGIAN OFFSHORE DIRECTORATE

General

Well 34/10-16 R is a re-entry of well 34/10-16, which found oil in the Brent Group in the Gullfaks Sør structure, 8 km south of the Gullfaks Field. The objective of the re-entry was testing and permanent abandonment.

Operations and results

Appraisal well 34/10-16 was re-entered (34/10-16 R) on 31 August with the semi-submersible installation Ross Isle.

The well was tested.

The well was permanently abandoned on 27 September 1983 as an oil and gas appraisal well.

Testing

Two drill stem tests were performed in the Brent Group.

DST1 perforated the interval 3397 to 3407 m and produced 960 Sm3 oil and 182 000 Sm3 gas /day through a 48/64" choke. The GOR was 191 Sm3/Sm3, the oil density was 0.86 g/cm3, and the gas gravity was 0.67 (air = 1). Maximum temperature recorded down hole was 129 deg C.

DST2 perforated the interval 3177 to 3187 m and produced 370 Sm3 condensate and 1 650 000 Sm3 gas /day through a 80/64" choke. The GOR was 4118 Sm3/Sm3, the oil density was 0.79 g/cm3, and the gas gravity was 0.66 (air = 1). Maximum temperature recorded down hole was 118 deg C.

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.
