Echo Energy plc, the Latin American focused upstream oil and gas company, is pleased to announce the commencement of drilling of the final well in the four well back-to-back campaign in the Company's Fracción D asset, onshore Argentina, operated by Compañía General de Combustibles S.A. ("CGC") in joint venture with Echo.

The well, in the western area of the Fracción D licence, targets a Tobifera high identified on 2D data, and is planned to be drilled to a measured depth of approximately 1,514 metres by the Petreven H-2015 rig.

The CSo-2001d well is targetting 19.0 bcf (gross best case) contingent resources, assigned to the prospect in the recent Competent Person's Report (CPR) produced by Gaffney Cline & Associates in addition to a further 18.7 bcf (gross best case) of prospective resources identified in the same CPR.

The Company will update shareholders with progress on the exploration drilling programme as the programme advances.
