This session provides the regulatory and environmental background, history, and framework for the development of unconventional reservoirs across Australia, and in specific states. The scope of discussion covers all applications in the workshop such as acquisition, sourcing and availability of water for HF operations; treatment options; and disposal options such as treatment followed by surface discharge, irrigation, and subsurface disposal into disposal wells. Related topics such as concern over drinking water, potable water aquifer, and land contamination will be discussed, as well as effective engagement strategies to overcome the negative perception that the general public has of the industry.
This is an overview session which will give operators and proponents an opportunity to describe the water-related challenges that they face in field development of CSG reservoirs. Emphasis will be on historical developments in the industry, the costs, and technical challenges across all water-related aspects of CSG development (drilling and completions, hydraulic fracturing, flow back, dewatering, produced water, brine management, salt, disposal, injection wells, etc.).
This is an overview session, on the subject of shale reservoirs, which will give operators and proponents an opportunity to describe the water-related challenges that they face in field development. Emphasis will be on historical experience in the industry, the costs, and technical challenges across all water-related aspects of shale development (drilling and completions, hydraulic fracturing, flow back, dewatering, produced water, brine management, salt, disposal, injection wells, etc.).
The emphasis of this panel session will be to provide an understanding of the water-related problems and costs being faced by the operators, proponents, and field development teams. Selected speakers from Day 1 sessions will take the podium and engage in a discussion of related topics. The audience will have the opportunity to engage the speakers in a discussion.
This session will focus on fundamental investigations of flow back and produced water chemistry, characteristics, biological aspects, and water treatment technologies. Technologies under development, pre-commercial, and those that are currently in use will be included. Laboratory and pilot studies carried out under controlled conditions, prior to field implementation will be emphasized. The various roles of various stakeholders (government, operators, and technology providers) in developing and implementing technology will also be discussed.
This session will focus on water quality requirements for drilling and completion including hydraulic fracturing, and the various sources of water and treatments requirements. Water quality requirements will be discussed in terms of the various drilling and completion fluids that are required. Opportunities for alternate water sources to replace or supplement fresh water will be considered. Opportunities for reuse and recycling of flow back water will be discussed.
This session will examine in some detail the question of how to best handle RO reject, concentrated brine, and salt. Options such as Selective Salt Recovery (SSR), Regulated Waste Facilities (RWF) will be discussed. The issues of concentrated brine transport, and handling will be considered. The viewpoint of the discussion will be to include cost, technologies, and environmental impact.
The breakout session is an opportunity for interaction among the attendees. It is designed to encourage participation, information exchange, and to consider projects (data collection, or formation of industry groups) that will allow the participants to collaborate after the workshop.
Highlights from previous workshops in the series will be presented. Previous workshops include:
This session will focus on treatment of HF flow back fluids for reuse, and recycling. For example, typical HF flow back fluids have high suspended solids, high polysaccharide content, and high Chemical Oxygen Demand. Technologies that can be used to treat these fluids will be discussed.
