Cairn encouraged by SNE North well results

07 August 2017 07:54

Cairn Energy is encouraged by results from the SNE North-1 exploration well offshore Senegal.

Cairn said the well encountered oil and gas in the primary objective and oil in the deeper secondary objective, in a separate accumulation to the SNE field.

It said further work was being undertaken to establish the potential commerciality of this discovery and to integrate the results with the block wide data gathered to date.

It said the well result had positive implications for further hydrocarbon potential to the north of the structural trend containing the SNE field and SNE North-1 discovery well, as well as for broader exploration potential in the permit.

The well is located in ~900 metres (m) water depth, ~ 90 kilometres offshore in the Sangomar Deep Offshore block and ~15km north of the SNE-1 discovery.

The well reached a total depth of 2,837m ahead of schedule and under budget.

Cair said its preliminary analysis indicated:

- ~24m of gross hydrocarbon column across three intervals

- ~11m net condensate and gas in high quality reservoir in primary objective

- ~4m net oil in good quality reservoir in deeper secondary objective (occurring below the SNE field Oil Water Contact)

- A slightly lighter oil type of 35° API than that encountered in the SNE field

Cairn said this marked the end of the five well 2017 drilling campaign and SNE North-1 was being plugged and abandoned and the Stena DrillMAX rig would be released.

It said the joint venture was reviewing the potential for further exploration drilling operations next year within the Rufisque, Sangomar and Sangomar Deep production sharing contract area.

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."
