- Caspian Sunrise said it had completed drilling of a deep well at the BNG contract area in Kazakhstan, though the commencement of a shallow well campaign had been delayed.

At the A5 deep well, which commenced from a depth of 3,976 meters, a side-track had reached a total depth of 4,404 meters.

'Abundant' hydrocarbon shows were observed while drilling, consistent with shows observed in a previous side-track, which had a successful short-term flow test, the company said.

Wireline logging had just been completed and evaluation of reservoir properties and fluids was ongoing.

Baker Hughes had been contracted to commence cementing work, which, if successful, would be followed by a 90-day flow test.

At the A8 deep well, extensive use of powerful coil tubing equipment had been followed by two separate acid treatments.

A mixture of oil, gas, water and drilling mud flowed to the surface, with pressure in the well remaining strong throughout the process.

'Our intention is now to close the well for a short period to confirm the pressure measurements before deciding how to proceed,' Caspian Sunrise said.

Once work at A8 had been completed, the company said it would seek to apply the same techniques on deep wells 801 and A6.

As for the upcoming shallow wells, the first of of 18 infill holes at the MJF structure was expected to start in December.

'Despite this delayed start we are still working to complete the full 18 well exercise by the end of 2020,' the company added. At 1:29pm: [LON:CASP] Caspian Sunrise Plc Ord 1p share price was -0.6p at 8.7p
