Northern Petroleum Plc announces offshore French Guiana GM-ES-3 exploration well operations extended

Northern Petroleum Plc  (AIM:NOP) announces the joint venture decision to extend  current drilling operations on the Guyane Maritime permit in French Guiana.  The GM-ES-3 exploration well is the second well of a four well exploration drilling campaign that commenced in 2012 to follow up the oil discovery at GM-ES-1 in 2011.The GM-ES-2 well had exploration objectives in the major Cingulata fan system within which the original oil discovery was made in two ages of formation. GM-ES-3 has been planned to deliver exploration information in the subsidiary Priodontes fan system to the north west of the Zaedyus oil discovery.

The GM-ES-3 well intersected a 50 metres gross section of oil stained sands in the lower part of the Bradypus fan which was not a target formation at this location although it is also within the main Cingulata fan system.  A 325 metres gross interval of sandstones was encountered in the targeted Priodontes fan, but these were logged with no significant hydrocarbon shows.

It has been decided by the Shell, Total, Tullow Oil and Northpet Investments Limited joint venture that this well provides a suitable location to drill deeper in a plan to penetrate the full post Atlantic rift sequence. The duration of this additional drilling will depend upon results from the formations encountered.

This information may prove crucial to a fuller understanding of the exploration potential of this very large licensed area.  Although this extension may cause a small delay to the further wells in this exploration programme, the earlier the deeper formations are examined, the better the advantages to be gained from its use in the second part of the drilling programme and aid efforts towards discovering more oil.
