Operations Update Colombia – Aureliano Well Spudded

Emerald Energy Plc (“Emerald” or the “Company”) is pleased to announce that the Aureliano 1 exploration well has been spud. The Aureliano prospect is in the Fortuna Association Contract area in the Middle Magdalena Valley in Colombia.

The Aureliano 1 well is targeting a fractured limestone prospect in the same La Luna formation, but across a fault from the Totumal field which produced 800,000 barrels from three vertical wells until the field was shut-in in the mid 1990’s. The well is planned to reach a measured depth of 8,600 feet and take approximately 35 days to drill.

Emeralds’ Chief Executive Officer, Angus MacAskill, said:

“This is a significant step in the exploration of the Fortuna area. The prospect, if successful, has the potential for a number of additional development wells.”
