Completed. Australia Pacific LNG is a coal seam gas (CSG) to liquefied natural gas (LNG) project constructed in Queensland. The scheme includes the development of CSG fields in the Surat and Bowen Basins, a transmission pipeline and a twotrain LNG facility on Curtis Island, near Gladstone. The twophased project took off for construction in 2012.
Seam Thickness The vertical thickness of a coal seam. Terminal Rate The flow rate at which a gas well is abandoned; usually either a function of project economics or technical ability of the well. Well Spacing The space between wells which influences the drainage area. Abandonment Permanently shuttingin and isolating a well.
When rockbursts and coal and gas outbursts simultaneously occur in a coal mine, changes in gas adsorption (concentration of ambient methane) and displacement of coal and rock must occur. The coassociated minerals in coal reservoirs can affect the mechanical properties and methane adsorption capacity, which are commonly disregarded. It is important to construct compound molecular structure ...
Abstract. Methane (CH4) is a potent greenhouse gas and a key precursor of tropospheric ozone, itself a powerful greenhouse gas and air pollutant. Methane emissions across Queensland's Surat Basin, Australia, result from a mix of activities, including the production and processing of coal seam gas (CSG). We measured methane concentrations over years from two monitoring stations established ...

The plant also has gas pretreatment facilities, a nitrogen rejection unit and two containment LNG storage tanks, each of 140,000m³ capacity. In addition, it has jetty and docking facilities ...
Coal seam gas is a form of natural gas typically extracted from coal seams at depths of 3001,000 metres. Coal seam gas (CSG), also known as coal bed methane, is a mixture of a number of gases but is mostly made up of methane (generally 9597 per cent pure methane). It is typically attached by adsorption to the coal matrix, and is held in the ...
Coal seam gas, also called coal bed methane, refers to naturally occurring methane in coal seams. The gas is held on coal surfaces and trapped by water pressure in the gaps and cracks in the coal seams. In order to allow the gas to flow, water is drawn away from the seams to release the gas into a gas well. The Victorian Government banned the ...
Coal seam gas (CSG) is an unconventionally sourced natural gas which usually contains approximately 95 + % methane, and is found adsorbed within the underground coal seams ... and another entity such as a new meat processing plant could benefit from utilising that business service. If access to water treatment is a critical component of the ...
Coal seam gas contingent resource estimates increased by per cent to 27,564 PJ ( Tcf; Table 1 and Table 2; Figure 1 and Figure 2). ... (Northern Carnarvon Basin) was drilled in January 2022 as a potential backfill field for the Varanus Island gas processing plant, but found no hydrocarbons (Santos, 2022). The implications of such ...
What is coal seam gas (CSG)? Coal seam gas, or coal bed methane (CBM, is a form of natural gas, typically extracted from coal seams at depths of metres. It is a colourless, odourless, nontoxic mixture of a number of gases but mostly made up of methane (generally 9597 per cent pure methane). Coal seam gas has been part of Australia's ...
Fig. 14 shows that specific coal seams were processed depending on the price of coal. The most significant example of processing of particular coal seams at high coal prices can be seen in 2016 for seam D and E (Fig. 14 b), and to a smaller extend seam B. The mean price difference for the washing of seams D and E was in general 30/t to 40/t ...
"In terms of the coal seam gas sector, we are finding that emissions per unit of gas that's produced is two to three times higher than has previously been estimated," Dr Kelly told ABC's
Located in Queensland, Australia, Shell's QGC business produces natural gas from wells drilled into coal seams in the Surat Basin. Its operations include over 3,000 production wells, 25 field compression stations, six central processing plants, two water treatment plants and a twotrain LNG export facility on Curtis Island.
Coal seam gas (CSG) is primarily methane a colourless and odourless gas, found in coal deposits formed over millions of years from fallen trees and other plant matter. Natural gas collects in underground coal seams by bonding to the surface of coal particles. The coal seams are generally filled with water and it is the pressure of the water ...
Coal seam gas, also known as coal bed methane, is a natural, colorless, odorless mixture of various gases (primarily methane) that is extracted from coal at a depth of ∼ m. The chemical composition of CSG and conventional gas is the same. ... Many power plants are located near coal seams, which would reduce the transportation costs [5].
Owing to the exhaustion of shallow coal resources, deep mining has been occupied in coal mines. Deep buried coal seams are featured by the great ground stress, high gas pressure, and low permeability, which boost the risk of gas disasters and thus dramatically threaten the security about coal mines. Coal seam gas pressure and gas content can be decreased by gas extraction, which is the primary ...
Energy giant Shell has set out plans to drill 145 new gas wells in Queensland over the next three years to supply local consumers and liquefiedgas export markets. Shell, Tokyo Gas and China ...

Demand for a cleaner source of energy is increasing in India. In the search for alternate energy sources, coal bed methane gas receives considerable attention for its potential as a good energy source. During the coalification process, methane gas is captured in the coal seams and later released during coal mining operations. Coal bed methane separation is crucial for both economic benefit and ...

The first project at the Reedy Creek coal seam gas processing facility is an expansion of an existing 30 MW onsite power station installed in 2013 with additional 10 high efficiency Jenbacher J620 gas engines, doubling the size of the plant to 20 units (60 MW). For the second project, Clarke Energy will supply the remaining nine Jenbacher J620 ...
The geological structures of the coal fields in China are complex. With a continuous increase in the mining depth, the coal seams show the characteristics of high gas and low permeability, and the disaster potential for a coal and gas outburst intensifies in the process of coal mining. Gas drainage is one of the primary measures used to prevent and control gas disasters. Effectively improving ...
Santos attributed a 12 per cent drop from 2007 levels of Cooper sales gas and ethane production due to a natural field decline. With current 2P reserves of trillion cubic feet in the Cooper Basin region, the company has said that its coal seam gas reserves in Queensland now exceed its conventional gas reserves in the Cooper Basin.
This is APA's second investment in coal seam gas processing facilities following the completion earlier this year of the 13 million coal seam gas processing facility at Kogan, ... a CSG processing plant, gas storage facilities and a high voltage direct current interconnector system including a 180km underground transmission
The coal seam lies at 12,316 working face, the mining gas content is about 4~6 m 3 /t, and absolute gas gush from the mine is 12~15 m 3 /min, which is a typical highstrength mining coal seam with low gas emission. As the depth and intensity of mining increases, conventional gas extraction can no longer meet requirements of safe operation.
