Frontier Oil Corporation has temporarily suspended the Nassipping-2 acid stimulation operation on SC52 located in the Philippines due to an obstruction in a section of the well.

Down-hole imaging of the well bore indicates that the likely obstruction is a bent 'packer' caused during completion of the earlier re-entry program.

The blockage has consequently restricted the access of the acid stimulation equipment to the relevant sections of the well bore. During the operations gas flows were consistently detected at the surface.

Frontier now intends to mobilize a rig to the project site to remove the obstruction and to implement and complete the stimulation program. Discussions with potential rigsuppliers have commenced in preparation for an early 2013 operation continuation.

At that time, Frontier will utilize the rig to test a prospective gas-bearing horizon of significance, lying below the currently identified zone.
