Cairn Energy’s SNE North-1 exploration well offshore Senegal has encountered an oil and pay pay.
The explorer today confirmed the well, which is 90 kilometres offshore in the Sangomar Deep Offshore block and 15km north of the SNE-1 discovery, encountered oil and gas in the primary objective and oil in the deeper secondary objective, in a separate accumulation to the SNE field.
Initial analysis indicates 24m of gross hydrocarbon column across three intervals, 11m net condensate and gas in high quality reservoir in the primary objective, 4m net oil in good quality reservoir in deeper secondary objective and a slightly lighter oil type of 35° API than that encountered in the SNE Field.
Chief executive Simon Thomson said: “The SNE North well results are encouraging in terms of further prospectivity and implications for the full block potential offshore Senegal.
“We are delighted to have completed a safe and successful drilling programme in Senegal this year with the Stena DrillMAX. An update on resources and the SNE development plans will be provided at our interim results later this month.”
A full set of oil, water and gas samples was recovered to the surface. After completing conventional logging, a series of Modular Formation Dynamic Testing (MDT) mini-fracs were obtained across the reservoir section to help calibrate the geo-mechanical model of the SNE field and aid development well design.
This marks the end of the five well 2017 drilling campaign. SNE North-1 is being plugged and abandoned and the Stena DrillMAX rig will be released. The Joint Venture is reviewing the potential for further exploration drilling operations next year within the Rufisque, Sangomar and Sangomar Deep Production Sharing Contract area.
