Cairn Energy on Wednesday, announced that the well testing program on the SNE-3 appraisal well offshore Senegal was successful.

According to the company, after the drilling, coring, logging and drill-stem testing (DST), the operation was carried out successfully without any harm. The well is currently being plugged and abandoned. 

The Study of the dataset gathered is ongoing. And initial results revealed that two drill stem tests were performed in the Upper Reservoirs, proving the deliverability of DST 1a which flowed at an extreme rate of ~5,400 bopd and a pricncipal flow rate of ~4,000 bopd in a 24 hour period from a 15 metre (m) zone while for the DST 1b, an extra zone of 5.5m was added to and a joint rate of ~5,200 bopd measured, with an supplementary main flow rate of ~4,500 bopd over a six hour period. The two main flow periods used a 56/64” choke.

The study also confirmed identical 32° API oil quality as witnessed in SNE-1 and SNE-2. Estimated resource for the SNE field is still undergoing revision and an update is to be declared at the company’s primary results on the 15th of this month. “Cairn is delighted with the flow rates from the latest well in the Senegal appraisal programme, which validate the scale and growth potential of the SNE field.  The results have demonstrated the ability of the upper reservoirs to flow at commercially viable rates and we eagerly look forward to the results of the BEL-1 well which will commence operations shortly,” Simon Thomson, Chief Executive of Cairn Energy told Energy-pedia.
