Cairn is pleased to announce the results of the SNE-4 appraisal well offshore Senegal where operations have been safely and successfully completed following drilling, coring and logging. The well is now being plugged and abandoned.

The SNE-4 well was appraising the eastern extent of the SNE field discovered in 2014 and aiming to confirm the nature of the upper reservoirs in the oil zone.

Cairn’s analysis of the dataset collected is continuing with initial results as follows:

Confirms the extension of reservoirs in the eastern extent of the SNE field, more than 5 kilometres (km) to the east and down dip of SNE-3

Confirms oil bearing Upper Reservoir sands of similar quality to those encountered as gas bearing elsewhere in the field

The uppermost gas sands first encountered in SNE-3 and BEL-1 were also present and gas bearing in SNE-4

Confirms correlation and presence of the principal reservoir units between each of the wells across the whole field

A gross oil column of ~100 metres (m) encountered, similar to SNE-1, SNE-2, SNE-3 and BEL-1

108m of continuous core taken across the oil bearing reservoir interval with 100% recovery

Multiple samples of gas, oil and water recovered to surface

Initial indications confirm similar 32° API oil quality as seen across the fieldir businesses.”
