- Caspian Sunrise said that work had commenced to take a third core sample from a well at its BNG contract area in Kazakhstan.

Drilling of the Deep Well A8 commenced in November, with a target depth of 5,300 meters and with two principal targets.

The first was in the Carboniferous, with an expected interval depth starting at about 4,300 meters, and the second in the Devonian, with an expected interval depth starting at about 5,200 meters.

At a depth of approximately 4,340 meters, there were several simultaneous indicators of hydrocarbons on a mudlog.

A first core was collected at a depth of 4,346 to 4,350 meters and a second over the interval 4,370 to 4,379 meters.

Samples analysed from this interval also showed visible secondary porosity and oil staining.

A preliminary analysis from the first two core samples showed them to be porous and oil and gas bearing.

'After further analysis of the two sections of core we are pleased to confirm that the samples analysed showed visible secondary porosity and oil staining,' the company said.

'Fluorescence and hydrocarbon cut tests classified the hydrocarbon indicators as fair to good.'

'Currently operations are ongoing to collect an 18-meter core from 4,379 meters to 4,397 meters.'

'For the avoidance of doubt, we believe the first two samples are from the same interval, which is believed to extend across the full 58km2 of the Airshagyl structure.'
