Περίληψη

Downhole zonal isolation requires the efficient removal of mud from the annulus and its replacement by competent cement. While good cementing practices have been developed over the years the results are not always satisfactory mainly because the techniques for mud removal are not optimized. Improved mud removal techniques have recently been developed which take into account quantitatively most of the parameters affecting mud displacement and cement placement. Application of these techniques has lead to considerable successes in the field. This paper provides further evidence of the effectiveness of these techniques by presenting the results of a field campaign.
