Royal Dutch Shell’s natural gas production from Egypt’s Burullus and Rosetta concessions has increased to 686 mcf/d from 640 mcf/d in late 2015, wrote Enterprise.

The Burullus concession accounted for 641mcf/day and the Rosetta concession was responsible for 45mcf/day of the total volume produced. The two concessions are among Egypt’s most important strategic sites for natural gas production, as they account for 25% of Egypt’s total gas production in 2012-2013, according to Al Borsa News.

The two concessions lose around 480 mcf of natural gas each year, such loss is anticipated to be recovered when the $1.3b worth Phase 9b becomes operational, Oil Ministry informed.
