Decommissioning of wells and well pads (plugging and abandonment of the well and rehabilitation of the well pad) is an important activity in coal seam gas developments due to the large number of wells drilled and their co-location with other land uses. Successful decommissioning will need to be conducted in a way that is effective, efficient, complies with regulatory requirements and is socially acceptable. This study sought to understand the perspective of industry, government and local stakeholders on the decommissioning process and asked the question ‘what does successful decommissioning mean’? The study was conducted through workshops held in Camden, Chinchilla and Narrabri involving industry, government and local residents. All stakeholders agreed that the goal of successful decommissioning is to effectively have no legacy issues arising from the abandoned well or well pad, in perpetuity. However, there were differences in the confidence that stakeholders had in the process of achieving this outcome, largely based on the varying levels of understanding of well abandonment. This lack of confidence and understanding contributes to cross-cutting themes that emerged from the workshops. Local stakeholders expressed a strong desire for independent oversight and assessment of well abandonment processes, with increased transparency and access to information on abandoned wells in an understandable form. They also stated that long-term monitoring of wells post abandonment would assist in providing them with confidence that wells can be successfully decommissioned.

Gas Market

Australia’s eastern gas market has historically been one of low prices and stable, long-term contracts. The development of coal seam gas (CSG) and the construction of Queensland’s three CSG to LNG projects is driving a tripling of gas production in eastern Australia and changes to historical patterns and directions of gas flows throughout the market. This transition from an isolated market to one linked to international LNG markets, coinciding with the unwinding of many legacy contracts, is leading to unprecedented change and will have profound effects on all participants. This extended abstract considers the implications of LNG exposure on the competitiveness of Australia’s eastern gas market. It will draw on the expertise of the gas market specialists in the Office of the Chief Economist, and the oligopolistic model of the market, to consider impacts on supply, demand, price, and the level of competition in various sectors of the market. One of the initial findings is that the volatility of global LNG spot prices is likely to have a significant impact on both gas production and demand in east Australia, given the scale of LNG exports relative to the eastern market. The extended abstract explores a range of LNG demand scenarios for the eastern gas market. It will emphasise the fundamental importance of expanded gas production on market outcomes, and the need for ongoing gas exploration and development to support the market through the transition.

This case study research examines informal adult learning in the Lock the Gate Alliance, a campaign against mining for coal seam gas in Central Gippsland, Australia. In the field of the campaign, circumstantial activists learn to think critically about the environment, they learn informally and incidentally, through socialization with experienced activists from and through nonformal workshops provided by the Environmental Nongovernment Organization Friends of the Earth. This article uses Bourdieu’s “theory of practice,” to explore the mobilization of activists within the Lock the Gate Alliance field and the practices which generate knowledge and facilitate adult learning. These practices have enabled a diverse movement to educate the public and citizenry about the serious threat fracking poses to the environment, to their land and water supply. The movements successful practices have won a landmark moratorium on fracking for coal seam gas in the State of Victoria.

AbstractCoal and gas outbursts are the result of several geological factors related to coal seam gas (coal seam gas pressureTo classify the outburst hazard level of a coal seam by means of statistical methods, this study considered the geological parameters of coal seam gas and statistical data on the amount of material involved in coal outbursts. Through multivariate regression analysis, a multivariate regression equation between the outburst coal quantity andUsing a significance evaluation of the aforementioned factors, the relative contributions of the gas-related geological parameters to the outburst hazard level of a coal seam were found to follow the orderThis work provides a scientific basis for evaluating the outburst hazard level of a coal seam and adopting feasible and economical outburst-prevention measures.
