Cairn Energy has successfully drilled its fourth appraisal well this year, offshore Senegal. Drilling, coring and logging have been completed at the SNE-4 ultra-deep water oil and gas discovery, the company informed.
“We have now drilled four successful appraisal wells in Senegal and we are delighted with the results to date of the multi-well evaluation programme, which has confirmed the scale and potential of this world class asset”, Cairn Energy CEO Simon Thomson said.
Drilling Discovers Further Reserves Say Cairn Energy
The SNE-4 found 328 feet of oil-bearing sands similar to the SNE-1, SNE-2, SNE-3 and BEL-1 wells.
It has also confirmed the extension of the reservoirs in the eastern extent of the SNE field and confirmed oil-bearing upper reservoir sands of similar quality to those encountered as gas-bearing elsewhere in the field.
Additionally, the company has confirmed the correlation and presence of the principal reservoir units between each of the wells across the field.
The well is now being plugged and abandoned.
“Operations in Senegal have been safely conducted and are ahead of schedule and substantially under budget”, Thomson explained.
“We have gathered a very large volume of data from operations to date and we look forward to progressing our long-term, multi-field, multi-phase exploitation plan to maximise value in Senegal”, he added.
Fourth Successful Find This Year
Cairn Energy holds a 40% stake in the SNE prospect, formed by three offshore blocks named Sangomar Deep, Sangomar Offshore and Rufisque. The remaining JV partners are ConocoPhillips (35%), FAR (15%) and Senegal’s national oil company PETROSEN (10%).
The well is the JV’s sixth offshore Senegal and its fourth completed this year as part of a programme to help outline the shape of the structure and establish the field’s prospects.
Ocean Rig Athena will now be demobilised.
Cairn has been active in Senegal since 2013, having made two significant discoveries in 2014.
