Irish exploration group, Petroceltic, today said that its Ain Tsila natural gas field situated in the Illizi Basin of Algeria is commercial.
The Final Discovery Report (field development plan), submitted in January 2012, along with the Declaration of Commerciality and supporting documentation will now be passed to the Algerian Competent Authorities.
Following their approval, the PSC parties will be granted a 30 year exploitation permit for the Ain Tsila field. Petroceltic holds a 56.625pc working interest in this development, with Enel holding 18.375pc and Sonatrach 25pc.
The field was formally declared commercial on completion of an agreement for Sonatrach to market all of the produced gas from the Ain Tsila field, using a formula linked to Brent oil pricing. The PSC partners estimate the field to contain gross resources of 2.1 tcf of sales gas, 67 mmbbl of condensate and 108 mmbbl of LPG. Development work is expected to commence in 2014 and first gas is planned for the third quarter 2017, initially from an estimated 18 vertical wells produced through a new gas processing plant at an annual average wet gas plateau rate of 355 million standard cubic feet/day (10.05 million standard cubic metres/day). The plateau length is 14 years and an additional 106 development wells are estimated to be required during the period to maintain this production plateau.
"The declaration of commerciality on the AinTsila field is a major milestone for Petroceltic and our partners Sonatrach and Enel. This is a critical step towards formally recognising the reserves on this substantial field and our asset team is now focusing on planning for the development phase of the project," said Brian O'Cathain, Chief Executive of Petroceltic.
