Injection of produced water for pressure support or disposal has always been challenging, in view of water quality and its potential negative effects. Achieving optimum and sustained injectivity throughout life-of well in a cost-effective manner are key objectives. This session addresses various efforts that have been implemented (successfully or not) in an attempt to achieve this desired objective. Discussions will center on fields results that may include process changes, new procedures, pilot tests, analyses, simulation and/or modelling. Furthermore, PWRI wells’ Injectivity restoration procedures and processes through stimulation will be addressed in this session.
