On completion of the stimulation campaign, production tubing will be installed ahead of the flowback of stimulation fluid and gas breakthrough.
Tamboran expects to release 30-day initial production (IP30) flow rates in Q1 2024, subject to weather conditions and the timing to flow back stimulation fluid to achieve gas breakthrough.
"We look forward to demonstrating the deliverability of the
"The stimulation of the SS-1H well incorporates lessons learned from the programs at Amungee NW 2H in Tamboran-operated EP 98 and Tanumbirini wells in Santos-operated EP 161. This includes an increase in hydraulic horsepower, higher well design pressures to increase effectiveness of stimulation treatments and fluid conditioning methodologies to decrease the risk of skin damage.
"The well was drilled with 5-1/2-inch casing to maximise proppant injection into the formation and will be completed with 10 stimulation stages over 500-metres (1,640 feet) at the toe of the horizontal section, representing 50-metre (164-foot) spacing.
"Results from the diagnostic fracture injection test (DFIT) have already demonstrated an over-pressured regime at the Shenandoah South location, with a pore pressure gradient of at least 0.54 psi/ft. This is in line with results demonstrated at Tanumbirini (0.51 - 0.56 psi/ft), which gives us confidence in being able to replicate or exceed the commercial flow rates achieved at the Tanumbirini location in the eastern 'core' of the basin.
"I look forward to updating the market following the completion of these activities and commencement of flow rates early in the new year."
