FALCON Oil & Gas has reported successful drilling of the Kyalla 117 N2-1H ST2 well in the Northern Territory’s Beetaloo Sub-basin.

The Irish company shares the well with operator Origin Energy (70%) and said late last week it had been drilled to total measured depth of 3,809 metres including a 1579m lateral section in the Lower Kyalla Formation.  

It said preparation work, which will include drilling water impact monitoring bores as required by the Territory's Code of Practice, will begin next month ahead of the next stage of operations.  

The JV will continue its in-depth shale evaluation of the technical data gathered from the conventional cores, sidewall cores and extensive wireline logging to build an understanding of the Kyalla Formation.  

"We are delighted to have successfully completed the Kyalla horizontal well section and we now look forward to the next phase of operations with the fracture stimulation of Kyalla 117 N2-1H ST2," CEO Phillip O'Quigley said. 

"We will continue to update the market as results become available."  

In early December Falcon said vertical drilling was completed to a depth of 1800m. 

Initial evaluation of the vertical section found three source rock reservoir sections identified within the Kyalla Shale Formation, with a thickness measuring almost 900m.

The three sections are known as the Lower, Middle and Upper Kyalla reservoirs. Gross thickness of each interval is between 75m-125m. 

 According Origin all three sections exhibited "elevated gas shows with relatively high C3, C4, and C5".
