Erhard Hornbogen,Hans Warlimont,Birgit Skrotzkiiple purposes such as providing mechanical support and zonal isolation, maintaining well performance, and restoring sealing barriers during the wellbore abandonment. However, Portland cement can have a brittle nature making it subject to mechanical failure at downhole conditions. To improve wellbore

Erhard Hornbogen,Hans Warlimont,Birgit Skrotzki recorded around late twentieth century. Globally, the regulation and minimization of CO. have consequently become a consensus. In South Africa (SA), most CO. releases are from burning coal and future forecasts show that CO. releases will increase more and more should there be no counter-progress in
