- The drilling of Lorelle-3 has measured a significant gas and condensate
resource within ATP 2056 in Queensland锟絪 Taroom Trough, with multiple
hydrocarbon-bearing intervals delivering above expectations.
- Wireline logging of the Lorelle-3 pilot has confirmed four material Permian
hydrocarbon bearing reservoirs making up 148m of total net pay which
includes:
o 28m of net pay in the Tinowon 锟紻unk锟� Sandstone with porosities up to 13%.
o 60m of net pay in the Lorelle Sandstone with porosities up to 14%.
o 59m of net pay across 6 separate zones in the Kianga Group of Sandstone
Reservoirs with porosities up to 17%.
o 1m of net pay in the Overston Sandstone with porosities up to 9%.
- The Tinowon 锟紻unk锟� Sandstone reservoir, which hosts an identified gascondensate resource, has been confirmed as the target for horizontal
drilling. Operations are to commence immediately following the plug-back
of the 8-1/2锟� hole section.
Elixir Energy Limited is pleased to provide the initial results
from the wireline and expanded evaluation campaign at the Lorelle-3 pilot well in ATP2056
within Queensland锟絪 Taroom Trough.
Elixir Energy Limited锟絪 Managing Director & Chief Executive Officer Stuart Nicholls said:
锟絋he initial results from the Lorelle-3 pilot well reinforce Elixir锟絪 position as a holder of some
of the most prospective acreage in the increasingly exciting Taroom Trough. Confirmation of
the northward extension of the Dunk play, with both thickness and reservoir quality
maintained beyond Shell锟絪 core operating area, significantly enhances the Company锟絪
opportunity to demonstrate commercial gas and condensate flow rates from the Lorelle-3
horizontal section, with drilling scheduled to commence imminently.
锟絋he strong upside delivered across the secondary targets represents an outstanding result
for the Company, with the Lorelle Sandstone coming in materially above expectations. The
interval appears exceptionally thick, laterally consistent and heavily charged with dry gas,
highlighting the scale and quality of the resource potential. These results are expected to
underpin a recommendation for an accelerated follow-up appraisal program to unlock and
test this significant gas opportunity, further enhancing the development potential of Elixir锟絪
broader Taroom position.
锟絀n the near term, our focus remains on executing the Dunk horizontal section, completing our
R&D program to optimise multistage fracture stimulation design, and progressing the well
through completion and flow testing over the coming months. Success in this program has the
potential to support the maiden Reserve booking for both Elixir and the Taroom Trough, a
significant milestone for the Company and the play.锟�
Operations Completed
Elixir has successfully completed the wireline and evaluation programs of the 8-1/2锟� section
of the Lorelle-3 pilot hole. Density/Neutron, Resistivity, Gamma, Sonic, Image and Nuclear
Magnetic Resonance (NMR) logs have been acquired along with whole and side-wall cores
across multiple identified hydrocarbon bearing reservoir units.
Along with the log program above, mud-logs and the data captured by the Logging while
Drilling tools have been used to evaluate the results of the Lorelle-3 pilot hole which includes
4-individual material gas and condensate bearing reservoirs. In the compilation of the final
results, Elixir has had its petrophysical interpretation peer reviewed by SLB. A description and
a summary of the results is included below:
Tinowon 锟紻unk锟� Sandstone
The top of the Tinowon 锟紻unk锟�
Sandstone (primary target) was
recorded at 3,175MDRT with a
gross thickness of 56m. The
reservoir is measured to be made
up of two sand packages of 21m
and 32m with a thin 2m coal sitting
in-between that is interpreted to
be not laterally extensive. The
Dunk Reservoir has 28m of net pay
and an average porosity of 8%
including peaks of 13% which is as
expected and is consistent with
the Shell well results to the south
which have flowed significant
quantities of gas and condensate.
The Dunk is measured via mudgas ratios and NMR logs to contain
a condensate rich gas resource
where 18m of whole core was
retrieved from the top of the
section which displayed
fluorescence in the cuttings.
Lorelle Sandstone
The top of the Lorelle Sandstone
(secondary target) was recorded at 3,386 MDRT with a thickness of 125m. The reservoir drilled
with a series of strong dry gas shows confirmed by the NMR logs and is measured to include
60m of net gas pay at an average porosity of 7%, including peaks of 14%. The reservoir is
measured as exceptionally thick, relatively homogenous in nature and presents a significant
future appraisal opportunity. Multiple side wall cores were collected in this reservoir where
descriptions have included the observation of some visual porosities.
Overston Sandstone
The top of the Overston Sandstone (also a secondary target) was recorded at 3,284MDRT with
a thickness of 102m. The reservoir is measured to contain a gas condensate resource and is
made of 1m of net pay with average porosity of 9% with side wall cores being collected over
this interval.
Kianga Group
The Kianga Group (tertiary target)
was measured at 2,917m MDRT
and is made up of 6 separate zones
which range between 4m and 16m
thick. The group contains a total
net pay of 59m with average
porosities of 9%, and peaks of 17%
and is measured to host gas
condensate resources. The group
includes the westerly equivalent of
Omega Oil and Gas锟� Canyon
Sandstone which appears
comparable1
. These additional
upside reservoirs bode well for the
opportunity of aggregating a bigger
liquids and associated gas
resource as part of a wider Taroom
Trough development plan.
The cutoffs used for the
petrophysical evaluation are
identical to those used by SprouleERCE in their existing 2C
Contingent Resource Booking in
ATP2056 and consistent with
Elixir锟絪 previous well result
disclosures. These results will be
further refined with physical core
calibration and additional
processing.
Forward Program
Elixir has completed the evaluation program and will now cement up the 8-1/2锟� reservoir
section of the Lorelle-3 pilot hole and conduct a BOP (blow out preventer) test. This will then
be followed by the commencement of a 1,000m+ horizontal sidetrack into the Tinowon 锟紻unk锟�
Reservoir and installation of casing in preparation for a multi-stage stimulation and flow test
in the second quarter of 2026.
About Lorelle-3
Lorelle-3 (L3) in ATP2056 (50%
EXR and operator of the L3
appraisal well, 50% STO and
operator of the permit thereafter)
located at 26锟� 58锟� 40.184锟絊, 149锟�
29锟� 15.986锟紼 is to be drilled in
two-phases. Initially the pilot hole
which has been drilled to 3,580m
total vertical depth has collected
core and logs in an expanded
evaluation program across the
various Permian sandstone
targets within the Taroom Trough
(Bowen Basin). Upon completion
of the pilot hole evaluation
program, Elixir intends to move
immediately into the second
phase of the drilling campaign
which will include the placement
of at least a 1,000m horizontal
sidetrack into the primary target
which will then be cased and
suspended for stimulation and
production testing.
The data and core gathered from
the expanded evaluation
campaign will lead into a series of
experiments and laboratory work
that will support the design and execution of an optimal stimulation. Elixir then intends to
execute a multi-stage fracture stimulation and production test at L3 prior to June 2026. This
sidetrack and flow test is designed to demonstrate commercial flow rates of gas and
condensate from the Basin Centred Gas Play and then lead into a possible maiden Reserve
conversion of the underlying Resource.
The L3 appraisal well costs associated with its qualifying activities that cover the drilling,
coring, logging, analysis, completion, stimulation and testing of the well, will be eligible for up
to a 48.5% refund via the Advanced Finding that Lorelle-3 has qualified for under the Federal
Governments Research and Development Tax Incentive and tax return processes.
L3 is now one of the highest impact wells in the Taroom Trough demonstrating a northern
extension of Shell锟絪 primary area of operations and drilling/testing within Tinowon 锟紻unk锟�
Sands. L3 is the first well drilled outside of the Shell acreage on the upper western flank of the
Taroom Trough and has validated the value, quality and materiality of Elixir锟絪 substantial
Taroom Trough acreage position.
