Platanillo 24 Update

Amerisur Resources Plc, the oil and gas producer and explorer focused on South America, is pleased to announce an update on operations in the Platanillo field in Colombia. 

Platanillo 24 has been tested and placed on commercial production at a rate of approximately 420 barrels of oil per day ("BOPD") in natural flow. An interval of 7ft was perforated in the Lower U sand only. Water cut is currently 0.1% with 80psi wellhead pressure through a 28/64" choke.

OBA volumes continue to increase, with current average daily throughput of 3,100 BOPD.

Subject to resolution of local social protests, the Company plans to mobilise the Serinco Rig D-10 to Pad 2N in order to drill the first appraisal well from that Pad, Platanillo 22.

John Wardle, Chief Executive Officer of Amerisur, commented:

"We are pleased with the result of Platanillo 24 and to have placed it onto commercial production and look forward to spudding Platanillo 22.
