With the rig contract being announced this week, this three-well program is a testament to the remaining potential of the A12 and B13 shallow gas fields in the Dutch offshore.
Taken into production in 2007 and 2011 respectively, these fields were discovered more than 20 years before, but were never thought to be commercial at the time.
The map above shows the outlines of the shallow gas fields in the northern part of the Dutch offshore. Apart from the A12 and B13 fields, Petrogas also currently produces from the A18-FA field and Dana Petroleum from the F02a field.
In addition, three more shallow gas fields will be producing within the next five years: A15-A, B10-FA and B16-FA. Again, this proves the commerciality of these shallow gas reservoirs, which are generally located at depths of around 500 m in unconsolidated Plio-Pleistocene deltaic sediments deposited by the so-called Eridanos delta.
TNO – Geological Survey of the Netherlands – performed a detailed study on the architecture of the Eridanos delta system reservoirs.
