COPENHAGEN, Denmark --Dong E&P has discovered more reserves in the Nini field in the Danish North Sea, close to the maritime border with Norway. The jack-up Noble George Sauvageau drilled appraisal well 5605/10-8 in 56 m (183.72 ft) of water.
The vertically drilled well reached TD in Danian chalk at 1,793 m (5,882 ft) below the sea surface. It proved the presence of oil and minor gas quantities in Paleocene sandstone in the eastern part of Nini.
To appraise the extent and quality of the oil-bearing reservoir, the rig drilled two side tracks, both with positive results, and logging/sampling data also confirmed the reservoir's productivity.
Dong and its partners RWE Dea and Altinex now will evaluate the results of this and an earlier appraisal well to determine the feasibility of an oil development. The rig will next drill a production well from the Nini platform into the central part of the field.
