SUMMARY
In Australia there are currently three operating natural
gas storage projects (Table 1, Plate 1):
1. a liquid natural gas (LNG) plant at Dandenong, Victoria,
2. a sub-surface sales gas storage in the Cooper Basin,
South Australia (S.A.).
3. a sub-surface ethane storage in the Cooper Basin, S.A.,
In addition, current available information indicates there
are at least seven domestic feasibility studies being undertaken
(Table 1, Plate 1) which may lead to the development of gas
storage:
1. in a disused coal mine (N.S.W.)
2. in two depleted gas fields Western Australia, and in one
depleted gas-producing coal shaft, N.S.W.
3. in aquifers in the Sydney Basin N.S.W.
in St Vincent Basin S.A.

Australian developments in surface and sub-surface storage of
natural gas. It covers in some detail the operating projects;
those under feasibility studies; and discusses in general terms
the concepts of the developments considered.
The purpose of the summary is to give factual information
regarding these dev~lopments and to give assistance in:
planning of new gas storage facilities,
formulation of policies for a possible national gas storage
program.
Data used in compilation of this summary were obtained
by the Bureau of Mineral Resources, Geology and Geophysics
(BMR) from:
State Mines Departments and their agencies,

GAS STORAGE
General Statement
Because natural gas is used mainly for industrial and household heating its
consumption rate is subject to considerable seasonal, weekly, and daily
variation. Seasonal demand variations are due mainly to the need for
domestic heating in winter, the weekly demand pattern is due to the
industrial weekend shut down, and daily demand variations are due to
household, and to a lesser extent industrial, demand peaks,. A pipeline
large enough to cope wi th.the peaks of a highly variable demand would be
unnecessarily expensive; a pipeline of a certain size can be economically
justified only if it operates at or near capacity throughout the year.
For a natural gas distributor the following are among the means
available to meet or control demand patterns:
development of gas storage near the points of use;
duplication of the pipeline;
restriction of consumption by means of complex contract arrangements;
variation of price structure in relation to demand.
Storage of gas near the final usage point offers possibly the most efficient
means of balancing pipeline energy supplies with a multiplicity of widely
fluctuating market requirements as well as providing security of supply.
Gas may be injected into storage when market requirement$.- fall below
available gas flow in the pipeline. It is withdrawn from storage when
market demand exceeds available supplies from other sources.
Storage Techniques
The main techniques used for storage of gas are:
- Depleted gas and/or oil fields,
5.
- Aquifers
Salt cavities,
- Abandoned coal mines,
Liquid natural gas (LNG) tanks.
The storage of natural gas in depleted gas and/or oil fields developed as a
sub-discipline of gas technology. The developments in storing gas in
aquifers have, however, raised gas storage technology to the status of a
special discipline.
The first attempt to store gas underground was performed in WeIland County ,
Ontario (Canada), in 1915, by re-injecting gas into a depleted field.
Since that time, numerous storages have been developed, first in the USA
then in Europe, and from 1980 also in Australia.
In USA at the end of 1983, there were over 420 gas storage pools (380 in the
depleted gas and/or oil fields; 40 in aquifers). In France the first
underground storage was put into service at Beynes, near Paris in 1956. At
the present time, France has 13 storage facilities: 11 in aqu.ifers and 2
in salt cavities.
The technique of storing gas in salt cavities is simple: it consists of
dissolving the solt with fresh water and draining off the brine from a
single well which will then serve for gas injection and withdrawal. Such
facilities are used in France, U.S.A., West Germany and Great Britain.
In Great Britain in 1980, the British Gas Corporation developed the first
storage of gas in a partially depleted gas field, the Rough Gas Field 20 km
off the Yorkshire coast near the city of Hull.
The storage of gas in disused coal mines is a practical proposition and the
developmental costs are comparatively low. Storage of gas in abandoned coal
mines was successfully developed in Belgium in 1976 where there are
currently two such storages operating.
6.
The storage of gas in liquid form (liquified natural gas - LNG) is a
further method by which gas can be stored reasonably efficiently in
relatively small storage systems. In this form 1 cubic metre of LNG is
equal to 600 cubic metres of natural gas at atmospheric conditions. A
numberof such storages are used world wide including one in Australia.
DEVELOPMENTS IN AUSTRALIA
Victoria
A liquid natural gas (LNG) plant at Dandenong, Victoria, (Plate 1, Fig.
1) was completed in early 1980 and is operated jointly by the Commonwealth
Industrial Gases Ltd (CIG) and the Gas and Fuel Corporation of Victoria
(Gas & Fuel Corp., 1983).
The plant includes the only LNG storage facility in Australia, and is the
first installation in the world to integrate an air separation plant with
an LNG liquefaction and storage facility. The basic function of the complex
is simple: the CIG Cryocentre liquefies natural gas from the Gas and
Fuel Corporation (GFC) in quantities sufficient for use by both parties.
CIG then uses the extreme cold of part of the LNG as a source of refrigeration
to liquify atmospheric gases for its own commercial, medical and industrial
use. This concept is unique in the world.
The plant's liquid natural gas storage tank has a capacity of 12 000
tonnes of LNG or the equivalent of 2 x 106m3 of natural gas. The LNG tank
is filled with gas from the Gippsland Basin, offshore Victoria, via a spur
to the 174 km gas pipeline from the ESSO/BHP Longford gas processing
plant.
The volume of LNG stored at the Dandenong plant provides an
invaluable back-up supply of natural gas to boost the Gas and Fuel
Corporation's in-hand gas capacity and improve the guarantee of security
of reticulated supply to urban, regional and industrial Victoria.
According to Gas and Fuel Corporation (1983), the storage volume of
LNG is sufficient to supply all their domestic consumers for about 2~
days in winter or up to 5 days in summer. I I .J

South Australia
Sub-surface storage of sales gas <llmd ethane in the Cooper Basin, SA,
is being operated by Santos Ltd (Plate 1).
The sales gas storage was developed in early 1980 in partially
depleted gas bearing lower Darolingie Beds within the Moomba gas field
(Plate 1, Figs 3 & 4). The stored sales gas volume rose initially from
83 x 106m3 in January 1982 to 189 x 106m3 prior to winter 1982 when a
portion of the stored gas was produced to meet peak demands. At the end of
1982 the volume of gas in storage3had increased to 285 x 106m3. The stored volume at the end of 1984 was 325 x 10 m .
The ethane storage was developed over the past three years and became
operational during 1984. According to Santos Ltd (1983), the storage utilises
the lower Daralingie Beds north of the present sub-surface sales gas
storage area. The ethane storage is part of the Cooper Basin producers long
rangeathanemarketability planning related to the establishement of a possible
petrochemical plant in South Australia. At the end of 1984, the volume of
ethane in storage was 64 x 106m3•
Sub-surface storage of natural gas in aquifers underlying an area north
of Adelaide has been under investigation since 1978 by the South Australian
Department of Mines and Energy (SADME Min. Ind. Quarterly No. 11, Sept., 1978).
The study has centred on the Tertiary sedimentary sequence beneath the
North Adelaide plains, in the Port Gawler and Brickland Park areas
following exploratory drilling and seismic surveys (Fig. 3).
According to the South Australian Department of Mines and Energy, an
area of about 5 km2 would be required to provide storage for some 5.0 x
109m3 of gas, which would be equivalent to about two months supply for the
Adelaide gas market. Such storage, if established, would provide
flexibility for the 782 km long Moomba to Adelaide gas pipeline and would
also offer an emergency supply if the pipeline failed.
9.
Western Australia
Sub-surface storage of natural gas has been contemplated by the
State Energy Commission (SECWA) since 1979 to assist in meeting peak demands
for the Perth, the south-western part of the State, and the Pilbara region
gas markets. According to the SECWA (1983), when the Northwest Shelf comes
into production and the Dongara field is no longer producing, the State
will be dependent for its gas supplies on one offshore gasfield (North
Rankin), with a single offshore pipeline and initially, a single production
platform.
Therefore a feasibility study to use the Dongara and the Woodada gas
fields (Plate 1, Figs 5, 6, 8, & 9) for storage of gas is being conducted
coinciding with the development of the Northwest Shelf gas resources and the
completion of the 1480 kmlong gas pipeline from Dampier to Perth. The
soon-to-be depleted Dongara gas field located 386 km north of Perth has
the capacity of storing up to 11.3 x 109m3 of gas. The second gas storage
field under consideration, the Woodada gas field, with a storage capacity
of about 0.7 x 109m3, is located 60 km south of the Dongara field. Both fields
are connected to the Dongara to Perth gas pepeline.

New South Wales
The highly populated and industrialised areas of New South Wales
are one of the largest markets for natural gas in Australia. Natural gas
supplies are brought into these areas by long-distance pipeline (Moomba
Sydney) 1300 km from the Cooper Basin in the northeast corner of South
Australia. During July 1982, an explosion in the western part of the Moomba
to Sydney pipeline threatened supplies to NSW markets, and highlighted the
need for a suitable gas storage facility to supply the major NSW markets
during times of emergency or peak demands.
For the past four years, the Australian Gas Light Comapny (AGL), NSW's
sole gas supplier, investigated a number of potential gas storage sites
in proximity to NSW markets. It conducted feasibility studies to store gas
in a disused coal mine, a depleted coal shaft, and in a number of aquifer
beds (Plate 1, Figs 10 & 11).
According to AGL, the disused coal mine (Burwood Colliery),
located near Newcastle, could store about four to five days' gas requirement
(approx. 40 x 106m3) for Newcastle, Sydney and Wollongong (Australian
Financial Review 30.7.82). Possibilities of storing gas in a depleted
gas producing coal shaft (Balmain Shaft) located in central metropolitan
Sydney is also being investigated by AGL (pers. comm. Mr T. Davis, AGL, June
1982). Gas produced from the Balmain Shaft was used during World War II
as an emergency fuel in motor vehicles. For this purpose, a production
rate of 3240 m3 per week was attained (Mayne et aI, 1974).
AGL is also investigating possibilities of storing gas in a number
of aquifers within the Sydney Basin (Plate 1, Figs. 10 & 11). These
potential storage reservoirs are favourably situated to the NSW gas
market and the existing gas pipeline. Their combined storage capacity
(Plate 1) would appear to be adequate to serve the NSW market for peak
shaving and security of supply. The current NSW daily demand is in the order
of 8 x 106m3.
13.
Northern Territory
During the past several years the Northern Territory Government has
given consideration to marketing natural gas in the Darwin area, particularly
of late in connection with electricity generation. Possible sources of this
gas have been remote fields in the Bonaparte Gulf and, more recently, fields
in the Amadeus Basin.
As all the possible supplies to Darwin are in remote locations, some
consideration has been given to possible storage in surface and sub-surface
(aquifer) facilities for peak demands. The information available indicates
that storage plans are currently at a very superficial level only.
Queensland and Tasmania
No developments in gas storage are known.
