Deris said Minister of Petroleum Bijan Zanganeh had spent a long time on investigation of the framework of the contract.
Once amendments are made in the NISOC contract and its framework is finalized, four fields of Parsi, Karanj, Rag Sefid and Shadegan, including nine oil reserves, are specified for development based on the contract after announcement and confirmation of the Minister of Petroleum.
The four fields were selected for the purpose due to the recovery coefficient, enhanced recovery and integration of the reserves, Deris added.
