The SS-1H flow test indicates that future development wells with lateral lengths of 10,000 feet may be capable of delivering average rates of 18.4 MMcf/d over the first 60 days of production.
Results continue to demonstrate that the 1 million acres below 8,850 feet (true vertical depth) in the Beetaloo West region is one of the most favorable places to anchor the initial development.
The SS-1H well is planned to be flow tested until IP90, which is planned to be announced in late
Tamboran continues to undertake Front End Engineering and Design (FEED) studies on the proposed
Tamboran Resources Corporation Managing Director and CEO,
"The SS-1H well continues to demonstrate a steady, low declining type-curve and holding its downhole pressure, which implies the well is connected to a world class reservoir with a strong pressure regime in the Shenandoah South area that supports initial development activities in the region.
"These rates continue to track average flow rates from some of the core regions in the
Shenandoah South 1H flow results
The SS-1H well in the Tamboran B2-operated Exploration Permit EP 117 achieved IP60 flow rates following the 10-stage stimulation program within the bottom 501 metres (1,644 ft) of the 1,020-metre (3,346 ft) lateral section in the
Testing was carried out following the installation of production tubing and a three-week soaking period to allow for water used in the stimulation process to be absorbed by the shale. The soaking aims to increase the relative permeability to gas of the formation and enhance future production performance.
During the initial draw down period from 25 January to
During the subsequent continuous flowing period from 8 to
During the following continuous flowing period from 25 February to 25 March (30 days), the choke was left unaltered at 43/64", resulting in gas rates ranging from 2.9 to 2.76 MMcf/d, with an average of 2.83 MMcf/d over the period. Flowing wellhead pressures were drawn down from 578 to 530 psi.
