Canada’s oil sands innovation alliance – leading innovation in oil sands tailings

Read abstract
Innovation flourishes at the intersection of great challenges meeting compelling solutions. COSIA enables environmentally focused collaboration, innovation and sharing. The unique characteristics of oil sands tailings provide our member companies with an opportunity to seek out innovative tailings management and technology solutions for responsible and sustainable growth of this key global energy resource. Canada’s oil sands producers are competitors and rivals. But they’re also partners in a made-in Canada collaboration model that is helping to redefine, globally, how companies can innovate together, and accelerate solution development to address some of the world’s biggest challenges. COSIA brings together leading thinkers from industry, government, academia and the wider public to improve measurement, accountability and environmental performance in the oil sands. Director of Tailings at COSIA, Dave Corriveau, will speak to delegates of the 22nd International Conference on Paste, Thickened and Filtered Tailings about COSIA’s portfolio and impressive progress towards advancing the innovation behind tailings management and technology solutions.

Dave joined COSIA in July 2018 from Shell International Exploration & Production in The Hague. His role in the Netherlands started in August 2013 as the manager of non-technical risks for upstream international operated, supporting an oil and gas production portfolio and development strategy across 12 countries where Shell is the operator and/or joint venture partner. Dave’s previous leadership roles included managing the Tailings and Water portfolio for Shell Canada Heavy Oil in Calgary. Prior to Shell, Dave worked 19 years for Teck’s Elk Valley Coal Corporation and its predecessor companies under Fording as well as NYCO minerals. His professional career experience during that time spanned across mining operations, engineering, strategic planning, business development, logistics and marketing. His very first adventures into underground mining date back to 1972 with his small family-owned prospecting company in Southern Sierra, Nevada. Dave completed his education at McGill University, earning a Bachelor of Engineering in Mining Engineering in 1989, and later an MBA in 2000 from the Richard Ivey School of Business, University of Western Ontario.

An economy and ecosystem symbiosis: barrier systems for water conservation and pollution control

Read abstract
An awareness of the rate at which water resource development took place in South Africa being supply driven until relatively recent times leads to an appreciation of the changing philosophy in respect of water conservation and pollution control, as well as essential amendment to principles and procedures. Reconciling water demand and supply in catchments requires concurrent consideration of available water quantity and quality. This stimulates the need for change in the way we view water uses and brings about business opportunities in the sector. The review of infrastructure designs in support of water use and mining applications for industrial and mining waste has developed and transformed along with improved technology and changes in legislation since 1994 in South Africa. A containment barrier system comprises of both filter protected drains and low permeability liners which are visible in the short term until covered. They are required to perform effectively after initial use and are often inaccessible for the operating period and subsequent service life of decades or even centuries. This paper presents a regulators perspective of commonly repeated deviation from accepted norms and standards in the engineering profession as applied to pollution control facilities. Emphasis is placed on the standards of today with experience reflecting on the past five years of design reviews, leading to conclusions and recommendations for facility owners and practitioners. Examples of procedure, mechanisms, performance, specifications and socio-economic benefits are addressed. It is postulated that in the near future many mining and industrial developers will choose to improve containment standards of barrier systems as a component of reengineering water demands and for economic advantage while embracing contributions from ecosystem services.

Kelvin is the Chief Engineer: Integrated Development in the Department of Water and Sanitation, RSA. He has over 35 years experience which extends from large storage dam developments, through associated civil, environmental and mining infrastructure, to waste management technology. Having specialised in the field of fluid flow through natural materials and geosynthetics, he is a member of SANCOLD, the International Geosynthetics Society, and SA Institute of Civil Engineers; and formerly the Chairman of the IGS Technical Committee on Filters (2014 – 2018). He leads the Department of Water and Sanitation engineering services review panel which advises the Authorities on pollution control and other resource protection works for licensing purposes.

Caius is a civil geotechnical engineer with close to 30 years’ experience in the water resources and mining industries. His areas of expertise are dam safety, dam engineering (water and tailings), portfolio risk management, geotechnical engineering and due-diligence for tailings and mine waste facilities. Caius spent 23 years in dam construction and consulting engineering before joining the Anglo American technical and sustainability corporate team in 2013, in Santiago, returning to Vancouver in 2019. He holds a PhD in Mining Engineering from McGill University, Montreal. He is a registered Professional Engineer in Ontario and British Columbia. During his career, Caius has been involved with various professional organisations, including the Canadian Dam Association, International Commission on Large Dams (ICOLD) Chile, the ICOLD subcommittee on Dam Safety, and the Mining Association of Canada.

 

Conference Co-Chairs

Professor Andy Fourie
Professor of Civil and Mining Engineering
The University of Western Australia, Australia

Andy is a Professor in the School of Civil, Environmental and Mining Engineering at The University of Western Australia in Perth.
He has Bachelors and Masters degrees from the University of the Witwatersrand in South Africa, and a PhD from Imperial College, University of London. He has worked at the University of Queensland, the University of Witwatersrand and has been a visiting professor at the University of Alberta, the Catholic University of Valparaiso in Chile and the University of Colorado in Boulder. His research is in the field of mitigating the impact of mining and municipal solid waste disposal. Outcomes from his research have been incorporated in changes to environmental legislation in South Africa. He contributed to a series of Guidelines for managing mine tailings in Australia, as well as developing a document for the International Atomic Energy Association on barrier systems for retaining uranium mining waste.

Dr Angus Paterson
Managing Director
Paterson & Cooke Consulting Engineers (Pty) Ltd, South Africa

Angus is the managing director of the Cape Town office of Paterson & Cooke, having founded the company together with Dr. Robert Cooke in 1991. The company now has offices in South Africa, USA, Canada, UK, Chile and Australia.
Angus completed his Civil Engineering degree at the University of Cape Town in 1984 and continued post graduate studies, completing an MSc in 1986 and a PhD in 1991. His research work focused on the flow behaviour of high concentration backfill slurry pipelines.
