The next set of recommendations from Norway's Gas Supply Committee (FU) could be postponed by two months.
According to the FU, its next proposals on fields to supply additional gas under existing Norwegian sales contracts should be submitted on 20 March.
The present deadline for presenting these recommendations to the Ministry of Petroleum and Energy is 15 January.
However, the FU points out that a number of changes have been made to data from some of the fields which are relevant to supply the required gas. A revised timetable has been submitted to the ministry for approval.
The ministry is expected to decide which fields will be allocated to supply additional gas in the summer, after the FU has submitted its recommendations.
