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.

Queensland coal seam gas (CSG) company Arrow Energy (Arrow) has implemented a safer, more efficient and cost effective approach to the transportation and supply of well materials to site. This paper examines Arrow’s approach to mitigating the transportation risks. It looks at current transport health, safety and environment (HSE) challenges, approach to address these risks, outcomes and future opportunities. The movement of well materials has been a concern for Arrow; it is a repetitive activity because wells are drilled, completed and worked over on a regular basis. Arrow’s challenge was to determine a better and safer way to load, unload and transport these materials. To address this material handling risk, an Arrow team developed a specially modified 40-foot flat rack (FR) capable of safely and securely holding a variety of materials. The FR can be picked up by a side-loader truck (swing-lifter), thereby enabling autonomous and safe loading and unloading. Warehouse staff can pre-pack all materials, thereby saving significant time for loading and unloading. Time and resources are also saved at the rig site where the FR can be unloaded autonomously. This unique design reduces human interaction and improves HSE personal safety risk significantly. A continuous improvement approach to further enhance the FR design to achieve better efficiency and safety for staff, as well as expanding its use to other business areas, is a key priority to Arrow.

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.
