Project summary
|
The coal seam gas water feasibility study examined the opportunities and risks of using coal seam gas (CSG) water in the Queensland Murray-Darling Basin (QMDB).
The study undertook a series of activities. Activities 1 to 7 investigated the risks of extracting and using CSG water, as well as analysing likely supply and demand. Activities 8 and 9 assessed specific opportunities for using CSG water in the QMDB.
The activities were:
coal seam gas feasibility study
activity 1: chemistry, origins and hydrogeology of coal
activity 2: modelling and forecasting of coal seam gas water production
activity 3: assessment of the salinity impacts of coals seam gas water
activity 4: stream ecosystem health response to coal seam gas water release
activity 5: vulnerability of aquifers to coal seam gas water extraction
activity 6: aquifer injection feasibility
activity 7: South West Queensland water demand analysis
activity 8: proposals for using coal seam gas water in the Central Condamine Alluvium
activity 9: proposals for coals seam gas water use in the QMDB.

Introduction: Strong LNG demand, both here in Australia and overseas, fuelled by worldwide transition to a low carbon economies is driving unprecedented growth in coal seam gas (CSG) exploration and development of east coast resources, not to mention the other conventional gas resources around Australia. With this accelerated growth in demand for gas, particularly with the onshore CSG production, comes the matter of the associated environmental affects and the need for socially responsible environmental management and mitigation of impacts. Why do I single out the CSG industry in this regard - after all the oil and gas industry has been the subject of considerable environmental regulation during the many decades of production in this country, and has a very proud record in doing the right thing. This paper relates specifically to one unique attribute associated with the production of CSG, namely the need to extract groundwater from the gas production wells in order that they be depressurised as a precursor to gas release. Pumping groundwater from of the coal seam 'aquifers' targeted for the resource reduces the hydraulic pressure to the point that the adsorption bonds holding the methane to the surfaces of the coal cleats (or microfractures) are reversed and the gas moves into the gaseous phase, and is hence available to flow to the well under the prevailing hydraulic gradients. Typically, a CSG well is pumped for its groundwater, producing its peak flows early in the life of the well, with flows of water tapering off with time, as gas flows increase and peak some years into its life. (Figure Presented) The consequence is, for a typical wellfield arrangement (of approximately 800 m by 800 m grid penetrations), considerable quantities of water are produced. We'll get to quantify this shortly. Copyright 2012, SPE/APPEA International Conference on Health, Safety, and Environment in Oil and Gas Exploration and Production.

Project summary

Management of coal seam gas (CSG) water is one of the greatest challenges facing the rapidly developing CSG industry in Queensland, Australia. The demand from regulatory bodies for beneficial use of CSG water, and regulatory disapproval of the traditional method of disposal through evaporation, has increased the need for cost effective, sustainable management options. The feasibility of aquifer injection of treated CSG water into the Great Artesian Basin (GAB) is being investigated as a sustainable management option by the Australia Pacific LNG Project under strict Government guidelines. This paper outlines the process of hydrochemical compatibility assessments under taken as part of these feasibility studies. Sites were identified as trial injection targets based on infrastructure location, presence of suitable aquifers and aquifer usage. Monitoring bores installed in the target aquifers have provided core and groundwater samples from which, key hydrogeochemical data has been collected. The assessments comprised PHREEQC modelling of water qualities of various injectate/aquifer blends and simplified 1-D reactive-transport modelling. To date, investigations have only been under taken at one site. Preliminary findings indicate that the target aquifer is a suitable target for injection trials and the injection of treated CSG water is unlikely to have adverse water quality effects on the target aquifer, if managed according to the injection plan.
