Falcon Oil & Gas has announced the start of stimulation activities at the Shenandoah South 1H (SS1H) well in Exploration Permit 117 in the Beetaloo Sub-Basin, Northern Territory, Australia, with Falcon Oil & Gas Australia Limited’s joint venture partner, Tamboran B2 Pty Limited.
The planned program, to be carried out by Condor Energy Service, will involve 10 stimulation stages within the Amungee Member B-shale over a 500-meter horizontal section of SS1H. The operation is expected to be completed by December 2023.
Once the stimulation campaign is finished, production tubing will be installed in preparation for the expected flowback of stimulation fluid and gas breakthrough.
“We look forward to this phase of operations in the Beetaloo with the stimulation and extended production testing of SS1H, with the planned program incorporating the lessons from previous programs, including Amungee NW-2H, and with the DFIT results providing confidence in the ability to achieve commercial flow rates. We will continue to update the market as results become available,” said Philip O’Quigley, CEO of Falcon.
Accordingly, the program will use higher hydraulic horsepower and well-designed pressures to improve the effectiveness of stimulation treatments, as well as implement fluid conditioning methodologies to reduce the risk of skin damage.
The results of the Diagnostic Fracture Injection Test (“DFIT”) have already shown that the Shenandoah South location has an over-pressured regime, with a pore pressure gradient of at least 0.54 psi/ft.
This is consistent with the results seen at the Tanumbirini well (0.51–0.56 psi/ft), giving confidence that the commercial flow rates achieved at the Tanumbirini location can be replicated or even exceeded.
It is expected that the initial production (IP30) flow rates will be released in the first quarter of 2024, subject to weather conditions and the time needed to flow back the stimulation fluid and achieve gas breakthrough.
