LONDON -- Pore pressure issues have halted drilling on Anadarko’s Collier 1 exploration well offshore Mozambique.
According to partner Cove Energy, the situation arose when the well had reached the top of the reservoir objective. At this point it was deemed unsafe to continue drilling.
As the well did not penetrate or evaluate fully the entire predicted objective section, the Rovuma Area 1 Offshore partners have agreed to suspend the well to allow re-entry at a later data, pending analysis of drilling data.
This is the second prospect to be tested in the deepwater block, following the Windjammer gas discovery earlier this year.
Cove says the drillship Belford Dolphin will continue its program on the block, starting with a well on Ironclad, a Palaeocene/Cretaceous prospect in the southern part of the 3D seismic area.
This will be followed by a well to the north on Barquentine, another prospect close to Windjammer.
