Dana makes significant gas discovery offshore UK

Dana has announced a significant gas discovery at the Platypus prospect in the UK Southern North Sea.

The Dana operated 48/1a-5 well was drilled in a water depth of approximately 142 ft to a total measured depth of 11 048 ft, targeting a high quality Rotliegend age, Lower Leman prospect. The well encountered some 218 vertical ft of good quality gas bearing sands and an extensive set of wireline log data is being acquired over the reservoir section.

Reserves in line with estimates

Preliminary analysis indicates that the reserves discovered are in line with pre-drill estimates of approximately 130 billion ft³ of gas. The Leman is the major producing reservoir in the Southern North Sea, and Dana is already producing gas from this reservoir horizon at the Johnston, Victor and Anglia fields. The Leman is also the reservoir in the Babbage field, which is currently being developed by Dana, with first gas expected in mid 2010.

Future plans

Following completion of the logging, a multirate drill stem test will be performed. The complete well dataset will then be fully analysed and development options assessed.

The 48/1a-5 well will be suspended for potential re-entry and future use as a gas production well. The Transocean GSF Labrador drilling rig will then immediately move to the Monkwell prospect in Block 42/29a, which is also operated by Dana.
