CARNARVON Petroleum is completing the NSE-A4 well in the Na Sanun East field, Thailand, as a development well while testing the L44-C well in the Wichian Buri oil field.

According to Carnarvon, the NSE-A4 well was drilled to total depth of 923m and penetrated a 35m thick upper volcanic section at 720.5m.

The company said the loss of over 23,000 barrels of drilling fluid indicates the section is highly fractured and would complete the well as a development well.

NSE-A4 is about 350m northeast of the NSE-A1 well site, which recorded good flow results from a newly discovered, 17m-thick upper volcanic/volcanic clastic reservoir.

Carnarvon said operator Pan Orient Energy is now drilling the NSE-B1 horizontal appraisal well at a depth of about 740m towards the top of the main volcanic reservoir objective.

The NSE-B1 is about 100m south of the new NSE-B drilling pad within the NSE central fault compartment.

Meanwhile, over at the Wichian Buri oil field, Carnarvon said testing is underway on four potential zones in the L44-C vertical appraisal well.

The company said the well was drilled to total depth of 1210m through multizone objectives within the F and G sandstones, and a deeper 210m-thick WB-1 volcanic reservoir.

Oil shows and elevated mud gas readings were observed at a number of stratigraphic levels while lost circulation was observed over two intervals within the WB-1 deep volcanic reservoir, the company added.

L44-C is part of a multi-well appraisal program intended to define the potential of the sandstone and volcanic reservoir targets in the up-dip portion of the POE-6 well and Wichian Buri fault compartments for future vertical and horizontal drilling.

Carnarvon Petroleum has a 40% interest in the Na Sanun East and Wichian Buri oil field respectively, while operator Pan Orient Energy has 60%.
