Comet Ridge Limited is pleased to provide an update on its plans for the Greater Mahalo Development Area, comprising the Mahalo Gas Project (COI 40%) and Mahalo North Project (COI 100%), as well as thoughts on gas market conditions which are currently impacting the industry.
- Comet Ridge believes the gas market should move from oversupply to being significantly short gas, around the time that the Greater Mahalo Development Area gas fields will be entering the market.
- Given the scale of the Mahalo Gas Project, the Company is investigating the sale of a portion of its interests to fund the equity component for that development.
- This enables Comet Ridge to concentrate its technical efforts on developing its 100% equity position
in the Mahalo North block (ATP 2048).
Gas Market Conditions
The impact of Covid-19 has seen softer energy demand globally, leading to weaker global oil and LNG prices. This has resulted in significant write-downs of the value of Australian LNG assets by the majors in recent weeks. The east coast gas market is currently in surplus because of weakness in international LNG demand as well as lower domestic gas demand. This has a flow on effect to local gas spot pricing and will lead to a corresponding industry-wide decrease in future investment in gas exploration and project development.
Recent quarterly forecasts by the Australian Energy Market Operator (AEMO), suggesting that Australia’s
east coast gas market will not be in shortfall until the end of 2023, may well be optimistic given the current
reduction in investment across the industry.
Comet Ridge expects a significant reversal of the current softer spot gas prices, from 2022/23 (if not earlier)
- Natural decline of tier 1 producing gas assets across the main producing basins of eastern Australia;
- A reduction in current and near-term investment, resulting in not only less new gas supply entering
the market than has currently been forecast, but existing fields without ongoing expansion drilling declining quicker than anticipated;
- A lack of government support and clarity for new supply sources from emerging gas producing regions (for example, AEMO are assuming 70 PJ of new gas per year coming into the New South Wales market by 2022); and
- The higher cost (on a lifecycle basis) of new gas resource development needing to be reflected in term contract pricing.
The Australian Competition and Consumer Commission (ACCC) Gas Inquiry 2017-2020 Interim Report
released in January 2020 indicates the long-term supply outlook for the East Coast Gas Market 2021 to 2031
is “uncertain” and the outlook for southern states is “highly uncertain”. The ACCC notes 2P reserves have
continued to fall, particularly in Queensland, where 2P reserves were downgraded by 4400 PJ between June
2017 and June 2019. The ACCC also notes that long term security of supply in the east coast is becoming
increasingly dependent on more speculative sources of supply, with 75% of 2C resources located in fields
(mostly from Bowen, Beetaloo, Galilee and Gunnedah basins) that are not yet in production or approved for
Comet Ridge supports the ACCC’s findings that “Governments should use active tenement management to
ensure producers bring gas to market in a timely manner, prevent larger producers ‘warehousing’ gas and
encourage greater diversity of suppliers”.
The confluence of the above factors, leads Comet Ridge to believe, subject to international LNG requirements, that the gas market should move from oversupply to being significantly short gas, around the
time that the Greater Mahalo Development Area gas fields will be entering the market.
ACCC notes in their January 2020 Report that the price of longer-term domestic contracts offered between
January 2018 to August 2019 for supply in 2020 has been in the $8-10/GJ range for producer offers (refer
Figure 1 below). Term contract pricing has been much less volatile than spot pricing, particularly spot prices
seen in recent times (including post COVID-19).
Mahalo Gas Project (PL 1082 and PL 1083)
Comet Ridge announced on 7 July 2020 that the Mahalo Gas Project had been granted Petroleum Leases
(PLs) 1082 (“Humboldt”) and 1083 (“Mahalo”) for a term of 30 years.
This means that Comet Ridge is now a 40% equity holder in a significant gas project that has received the
necessary government approvals to proceed to development and production. Whilst the Mahalo Joint
Venture (Santos 30% equity and APLNG 30% equity (with Origin as the Upstream Operator)) has agreed the facility at Mahalo will target 60 TJ/d gas production, the Joint Venture has yet to formally agree a date for Final Investment Decision (FID) or for First Gas.
Given the scale of the Mahalo Gas Project, the Company is investigating the sale of a portion of its interest
to fund the equity component for that development (notwithstanding the project will also have a significant
debt and tolling (opex) component). This will enable Comet Ridge to concentrate its technical efforts on
developing its 100% owned Mahalo North block (ATP 2048) which is discussed in greater detail below.
Mahalo North (ATP 2048)
Whilst working with our Mahalo Joint Venture participants to progress the Mahalo Gas Project to FID, Comet
Ridge has been progressing plans at Mahalo North, where 100% equity and operatorship provide the
Company with the ability to control the timing of work program, initial gas delivery and expansion. Comet
Ridge will look for operating synergy between Mahalo North and any other gas projects in the area for the
purpose of generating the lowest unit cost of gas. Comet Ridge however will not do this at the expense of
project timing nor operational control.
Following the announcement of the award of ATP 2048 on 30 April 2020, Comet Ridge has been working to
optimise the work program at Mahalo North to fast track potential commercialisation. Recently integrated
(additional) third party, high quality, seismic data has increased the Company’s confidence in the productive
coal fairway and the ability of strategically placed pilots to deliver meaningful gas volumes. The high quality
of the newly obtained seismic data means it is likely that a further planned seismic survey will not be
necessary and that appraisal and initial development wells can be located based on the data already
available and interpreted.
Given the current unfavourable gas and corresponding share market conditions, Comet Ridge is unlikely to
raise equity funds to undertake an initial pilot drilling campaign at Mahalo North. Rather, the Company has
been working with potential partners who share Comet Ridge’s view of a looming tightening gas market to
bring Mahalo North into production to coincide with the predicted shortages in the market. These negotiations, designed to provide funding for upstream appraisal and development, include gas pre-sales
and/or project equity participation. These negotiations, once finalised, may also incorporate a sell down of
part of Comet Ridge’s share of the Mahalo Gas Project (as indicated above).
Existing infrastructure near to Mahalo North, as well as the potential to supply gas to substitute diesel at
nearby coal mines, provides for a staged development profile and early production from Mahalo North.
Comet Ridge has been developing an opportunity to commercialise well test and ramp up gas from the initial
pilot phase of the Mahalo North appraisal work. Comet Ridge is finalising a Memorandum of Understanding
(MOU) with Mine Energy Solutions Pty Ltd (MES) and the Intelligas Group of Companies for the offtake and
transport of gas from Mahalo North for substitution of diesel for mine trucks at nearby coal mines and also
possible distribution into the local pipeline network. Such an option could provide flexibility for initial gas
production and provide an early revenue stream and environmental benefits for gas that would otherwise
be flared. Comet Ridge would see a significantly reduced facility capex requirement for this early gas
MES is an incorporated joint venture between Sime Darby Berhad, a multi-national corporation and
Intelligas, a Queensland based alternate fuels technology development company. MES has developed a high
density compressed natural gas fuel system for mine trucks that displaces diesel at high substitution rates.
This has both environmental and cost of production benefits for the mining operation.
Comet Ridge issubsequently progressing numerous options for commercialisation of gas from Mahalo North
through a combination of the following:
- “Virtual Pipeline” (i.e. trucking compressed natural gas “CNG”) – providing pilot gas to MES for substitution of diesel for mine trucks and/or possible distribution into the local pipeline network;
- Accessing nearby pipeline infrastructure – Comet Ridge has previously announced an MOU with Denison Gas for up to 10TJ/d; and
- New tolled pipeline and gas processing facilities once the Mahalo Gas Project development is completed.
Greater Mahalo Development Area plans
Comet Ridge believes it is prudent to take a staged approach to the Greater Mahalo Development Area,
targeting Mahalo North for early gas, initially at low cost and lower offtake to generate revenue. This would
be followed with expansion at Mahalo North and development of the Mahalo Gas Project utilising a partial
sale of equity, gas prepays, tolling arrangements and debt to provide funding.
Comet Ridge is progressing the following key milestones for development of its interests in the Greater
Mahalo Development Area:
- Secure a partner for the Mahalo Gas Project (which may incorporate appraisal and development funding and project equity interest in the Mahalo North block);
- Initial pilot drilling at Mahalo North designed to achieve 2 to 3 TJ/d of production per pilot well and expand the Company’s gas reserves in the Greater Mahalo Development Area;
- Infrastructure access initially via Virtual Pipeline or nearby existing infrastructure and subsequently via a tolled (shared) pipeline and processing facility for up to 60 to 80 TJ/d (gross) from development of the Mahalo Gas Project;
- Gas offtake arrangements for pilot gas initially and then expanding up to the total requirements of the Greater Mahalo Development Area;
- Joint Venture agreement on a Final Investment Decision at the Mahalo Gas Project;
- Access reserve-based lending facilities, loans from Commercial Banks or from Government backed infrastructure development funds to complement Comet Ridge’s development funding requirements.
Comet Ridge believes the following production profile can be achieved for the Greater Mahalo Development
Area. This plan is conceptual and subject to the necessary joint venture and government approvals as well
as finalising infrastructure access, gas offtake and development funding.
The Company sees the gas market tightness re-emerging in the short to medium term and is taking steps
now to participate in this opportunity by allocating capital and human resources across the portfolio in an
Comet Ridge believes that Mahalo North and Mahalo Gas Projects are standout, low cost, near to production
assets in a market that will ultimately move into significant undersupply. Given current share market
conditions, the Company is pursuing non-equity market solutions for Mahalo North development funding in
the form of project equity participation and/or gas prepay arrangements.
