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.

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.

Biomass-derived coal or “biocoal” produced using a torrefaction process presents a carbon-neutral option of coal for power generation. While torrefaction delivers a carbon content and hydrophobicity comparable to coal, it lowers its density and creates material handling, storage, and transportation challenges. Densification into briquettes would help mitigate these challenges. However, the torrefied biomass is difficult to densify and may require the use of binders, which are expensive and can be incompatible with respect to material and emissions. A cost-effective approach to utilize lignin in-situ of the biomass to promote binding during densification was demonstrated using a pilot-scale briquetter unit during this study. Lignin, a cross-linked polymer, tends to break down and lose its binding ability under high-temperature conditions of torrefaction. In this paper, we investigated the use of a lightly torrefied material as a binder―LTM (biomass torrefied in the transition region of non-reactive and reactive temperature ranges of torrefaction). When mixed with torrefied biomass and densified together under suitable moisture and temperature conditions, the lignin is shown to mobilize and provide binding to the briquettes. The results showed that briquettes produced using LTM as binder and 10% to 11% moisture provided in-situ binding, improved density and durability, and produced hydrophobic briquettes.
