Check out the great summary article, Maintaining Injectivity of Disposal Wells: From Water Quality to Formation Permeability, in the JPT – which dives into injectivity issues for Disposal Wells.
Poor water quality characteristics in injectate can jeopardize injectivity in even high-quality formations by rapidly decreasing permeability. The Saudi Aramco authors of this paper offer general guidelines for disposal water quality to maintain injectivity, a central topic of our Underground Injection Risk Report.
