Falcon wraps up flow tests at Kyalla 117 in Beetaloo
London-listed Falcon Oil & Gas has finished production testing at the Kyalla 117 N2-1H ST2 well in the Beetaloo sub-basin, in Australia's Northern Territory, the company said on October 7. The company is partnered with Origin Energy in the project.
Falcon announced back in July that Kyalla 117 had flowed liquids-rich gas without assistance for intermittent periods. Production was not sustained and there were indications of a potential downhole flow restriction.

On September 14, coil tubing operations restarted at Kyalla 117. No apparent restriction or blockage was identified in the production casing. Following a nitrogen lift, the well was able to flow unassisted at rates between close to zero and 1.5mn ft3/day for five days before loading up with water.
“Gas compositions data are not yet available but gas specific gravity data is similar to that measured during the previous phase of testing. Trace condensate was also observed,” Falcon said.
The company will undertake further analysis, including additional core analysis and well design considerations, to conclude on the results from operations at Kyalla 117. This will inform the future approach to further drilling and testing of the Kyalla play in the Beetaloo.
The purpose of the current exploration campaign was to collect data across the three primary plays within the permits: Velkerri dry gas, Velkerri liquids-rich, and Kyalla liquids-rich.
“Despite the challenges, the Kyalla remains a viable target within the Beetaloo. Kyalla 117 was the first horizontal well targeting the Kyalla and achieved its primary technical objective of demonstrating liquids-rich gas flow potential of the Kyalla,” Falcon said.
