Release: Cooper Energy: Kurnia-1 oil and gas show
Friday, August 31 2007 - 02:37 AM WIB
(31 August 2007)--We are pleased to announce that Kurnia-1 has encountered a drilling break (increase in rate of penetration) associated with oil and gas shows over an 8 metre gross sandstone interval from 1,783 to 1,791 metres.
The drilling break resulted in gas concentrations in the mud rising from a background level of 30 units to 224 units before the gas cut mud was circulated through the rig degasser with an increase in pressure on the choke manifold. The mud weight was increased to control any further gas influx.
A maximum gas reading of 3,132 units was recorded when normal circulation was resumed. The sandstone samples exhibited oil stain and increasing fluorescence with depth (100% fluorescence at 1,791m) and oil was observed on the surface of the mud.
The rig is currently conditioning the drilling mud prior to drilling ahead and at 8:00am WST was at a depth of 1,793 metres.
The significance of these gas and oil shows will be evaluated by wireline logs after the well has reached total depth of this section at 2,500 metres.
The next ASX release is expected to be after we have run the aforementioned logs and evaluated the significance of these hydrocarbon shows. (end of release)
