ADX Energy Ltd. revised resources in licenses ADX-AT-I and ADX-AT-II in upper Austria to 72 MMboe from 60 MMboe based on new technical work and the recent Anshof discovery and is seeking farmin partners for its Upper Austria portfolio (OGJ Online, Jan. 6, 2022).
The main revisions to the portfolio are the result of the Anshof-3 discovery now being moved to an appraisal category and the adjacent and newly mapped Gruenburg prospect being matured and added to the portfolio.
Likely resource estimates for the Anshof discovery remain unchanged as the Anshof-3 well intersects the Eocene primary oil reservoir target close to prediction (4 m high to prognosis); however, the shallow gas discovery within the overthrust imbricate sandstone reservoirs has not yet been included in the resource portfolio due to ongoing technical evaluation work.
Positive well test results expected next week could increase ADX reserves and production base in a short period of time, the company said.
The newly mapped and fully evaluated Gruenburg prospect lies immediately south of the Anshof discovery and could, in the case of a successful exploration well, be developed in conjunction with Anshof field. The Gruenburg prospect has been significantly de-risked by the successfully flow tested Aschach oil discovery which was drilled just north of the Gruenburg prospect into a small thrust and back-thrust fault related compartment.
