Produced Water events highlight latest developments
Over the past two decades, TÜV SÜD National Engineering Laboratory has supported many activities related to produced water (PW), aimed at improving produced water measurement and management practices. The annual Produced Water Club Meeting and Workshop continue to be key events for knowledge transfer in this area.
Produced water is an inevitable by-product of oil and gas production. Co-produced along with oil and gas during normal production operations, the current worldwide average estimates that for every barrel of oil produced, there are roughly four to five barrels of water co-produced. As a result, measurement of oil in produced water concentration becomes an important subject, not only for regulatory compliance monitoring but also for operations, and data collection for the development of future government regulations and corporate environmental policy.
In June 2019, TÜV SÜD National Engineering Laboratory organised its 17th annual Produced Water Workshop in Aberdeen. The Workshop is a two-day technical event, intended to keep participants up to date with the latest technological and legislative developments, as well as current practices and trends in produced water management, treatment and handling. Several key issues for the industry were discussed over 20 presentations, including the analysis and characterisation of naphthenic acids, environmental challenges for disposal and PW quality and oil in water (OiW) measurement, including the use of online analysers for reporting.
“With over 60 attendees from 11 countries, the Produced Water Club and Workshop continues to draw a varied audience of expert contributors”, commented Principal Consultant Dr Ming Yang. “Very strong support was received from the UK regulator BEIS, and operators including Aker BP, Equinor, Petrobras, Premier Oil, Shell and Total SA. Other operators represented include Aramco, CNOOC International, Inpex, OMV Exploration and Production and SBM Offshore. In addition, we have received strong support from organisations such as NIVA, Nalco / Champion, Proserv, Schlumberger, SINTEF, Suez, Sulzer Chemtech, Veolia and many of our Club members. I was delighted to see so many of the operators attending and the mix of the audience was fantastic.”
The Produced Water Club was founded in 2003 and amalgamated with its Oil-in-Water Monitoring Club in 2012. The Club aims to keep members abreast of technological and legislative developments in PW measurement and management, share knowledge and promote best practice. Members have access to regular e-zines and a members-only website which contains over 800 technical documents. They can also attend Club meetings free of charge and have input into the technical direction of the Club.
Earlier this year, a Joint Industry Project (JIP) was launched, to fill a significant knowledge gap in the oil & gas industry’s use of online oil-in-water analysers to help optimise oil and gas recovery. Scheduled to begin in July, the JIP will aim to deliver a new set of regulatory requirements for subsea produced water discharges, as well as guidance for the acceptance of using online oil-in-water analysers for unmanned and subsea applications. “Ultimately, the JIP will help the industry in making the use of online oil-in-water analysers for the discharge of produced water from manned, unmanned and subsea installations a common practice”, says Dr Yang. Four operators, including two National Oil Companies, have already committed to participate.
