To accelerate the campaign, the Perth-headquartered company said it was using two rigs to drill continuously throughout the remainder of the year and into 2008.
The newly operational Aztec-14 rig was yesterday drilling the first well, L44-G, ahead at a depth of 264 metres.
Located 7.3km north of the POE-9 discovery well, the L44-G appraisal well lies on the northernmost extent of the Na Sanun East structure.
Carnarvon said this well it would help determine the northern extent of the discovery before it applies for a production licence.
Drilling is expected to take 20 days to reach a 1600m and is targeting at least four potential volcanic reservoir zones.
The company also plans to spud the NS-3D1 well at the same field in the next five days.
The well will be directionally drilled from the Na Sanun-3 well site into the adjacent POE-9 fault block and into the main volcanic reservoir zone.
NS-3D1 is the first of a four to five deviated well program that will appraise the southernmost two fault compartments of the POE-9 oil discovery.
Depending on the results, this deviated well program will be followed up with a multi-horizontal well infill program of the southernmost two POE-9 fault compartments.
