Ascent Resources (LON:AST) has flowed gas from an open-hole test of the Karpatian reservoir of the Pg-11A well at the Petišovci project in Slovenia.
The top part of the sandstone reservoir was cored and the well deepened to expose approximately 50 metres of reservoir. An open hole test on this section produced and flared good quality hydrocarbon gas at a rate of about 2,500 cubic metres per day (90 million standard cubic feet per day).
“Operations are progressing steadily at our Petišovci Project in Slovenia and we are pleased that the first test on the Karpatian proved the presence of producible gas,” said managing director of Ascent Resources Jeremy Eng.
“The lower than expected carbon dioxide levels in the gas, if confirmed by laboratory analysis, will be advantageous as CO2 processing equipment may not be required in the early stages of the redevelopment,” he added.
Gas samples and the core will now be analysed and integrated with the extensive geological and engineering data already obtained from the well.
The company plans to drill another 450 metres to the planned total depth of 3,500 metres to delineate the full extent of the reservoir.
The well may require hydraulic fracturing; however, Ascent noted that the Karpatian may produce at commercial rates unstimulated.
Operations on the Pg-11A restarted in April this year and it has since been re-drilled to a depth of about 3,000 metres.
Back in March, Ascent raised £17 million via a share placing to advance the Petišovci/Lovási/Ujfalu project, through the drilling and completion of the Pg-11 sidetrack, the Pg-10 and Ujfalu-III wells, and capitalising on the area’s P50 estimated gas in place of 412 billion cubic feet (Bcf).
