 Amungee NW-1H –  Normalised Gas Flow Rate Equivalent to 5 MMscf/d per 1,000m Horizontal

 3 September 2021 – Falcon Oil & Gas Ltd. (TSXV: FO, AIM: FOG) is pleased to provide results of the production log test at the Amungee NW-1H well (“Amungee”). The results suggest a normalised gas flow rate equivalent of between 5.2-5.8 MMscf/d per 1,000m of horizontal section.

Amungee is located in the Beetaloo Sub-basin, Northern Territory, Australia and the testing conducted is part of the 2021 work programme which is operated by Falcon’s joint venture partner, Origin Energy B2 Pty Ltd., a wholly owned subsidiary of Origin Energy Limited (“Origin”).

 Amungee Background

  • Located in Exploration Permit 98, approximately 60 kilometres east of Daly Waters, just south of the Carpentaria Highway.
  • It was the first horizontal well to be drilled and first well to be fracked with Falcon’s JV partner and operator, Origin.
  • In November 2015, the JV successfully drilled the well to a total measured depth of 3,808m, including a 1,100m horizontal section.
  • In September 2016, 11 hydraulic stimulation stages were completed along the horizontal section in the Middle Velkerri B shale zone.
  • In December 2016, a 57-day extended production test (“EPT”) was completed, with production averaging 1.10 MMscf/d.
  • In February 2017, the Results of Evaluation of the Discovery and Preliminary Estimate of Petroleum in Place were published for the Velkerri B Shale Gas Pool, confirming a gross contingent resource of 6.6 TCF, 1.46 TCF net to Falcon, full details are contained in Falcon’s AIF.

Details of Amungee Testing

  • The well was successfully put back on production testing on 7 August 2021.
  • Initial flow rates during the first 48 hours of testing ranged between 2 – 4 MMscf/d with rates averaging 1.23 MMscf/d over the first 23 days.
  • A PLT was run on 19 August 2021 to 3,098mMD, just prior to the casing deformation at 3,112mMD.
  • The PLT data confirms that:
    • Only 5-15% of the production came from stages 1-7 beyond the casing deformation point at 3,112 mMD.
    • 85-95 % of the production came from stages 8-11 spanning a 200m horizontal section, prior to the casing deformation.
  • The low contribution from stages 1-7 is likely the result of a restriction caused by the casing deformation or the plugs having not milled out, or both.
  • Conclusion: stages 8-11 may be representative of the deliverability that can be achieved within the Middle Velkerri B Shale at Amungee.
  • The PLT test results equate to a normalised gas flow rate of between 5.2-5.8 MMscf/d per 1,000m of horizontal section.
  • A typical future production well would be likely to have a horizontal production section up to three kilometres.
  • The result validates the decision to undertake a second EPT in order to run a PLT.

 Philip O’Quigley (CEO of Falcon) commented:

“With our unique and extensive position in the Beetaloo Sub-basin, this is really exciting news for Falcon shareholders and this significant development provides line of sight to the commercialisation of the Beetaloo, for which we remain carried for further activity.

A recent report by an industry analyst suggests that gas flows greater than 3MMscf/d from a 1,000m horizontal well are required to demonstrate the commerciality of the Beetaloo. Not only does this test result significantly exceed these parameters and significantly increase our assessment of the Velkerri dry gas play, but it also puts the Beetaloo on a par with other shale gas basins in North America.

While we wait for further news from our operations at Kyalla 117 N2-1H ST2 and Velkerri 76 S2-1, we look forward to working with our JV partner, Origin, in establishing the next phase of work on the Middle Velkerri B Shale.

With other drilling activity in neighbouring Santos-operated blocks targeting the Velkerri dry gas play, this is an important moment for the nationally significant Beetaloo Sub-basin.”

Advisory regarding oil and gas information

Any references in this news release to initial production rates are useful in confirming the presence of hydrocarbons; however, such rates are not determinative of the rates at which such wells will continue production and decline thereafter and are not necessarily indicative of long-term performance or ultimate recovery. While encouraging, readers are cautioned not to place reliance on such rates in calculating the aggregate production for Falcon. Such rates are based on field estimates and may be based on limited data available at this time.

Contingent resource estimates are those quantities of gas (produced gas minus carbon dioxide and inert gasses) that are potentially recoverable from known accumulations, but which are not yet considered commercially recoverable due to the need for additional delineation drilling, further validation of deliverability and original gas in place, and confirmation of prices and development costs. There is uncertainty that it will be commercially viable to produce any portion of the resources. For additional information relating to contingent resource estimates in respect of the Amungee NW-1H Velkerri B Shale Gas Pool which were prepared by an Origin employee and a Qualified Reserves and Resources Evaluator effective as of February 15, 2017, please refer to Falcon’s Annual Information Form dated April 26, 2021, which is available on SEDAR at
