| Summary: | Contamination of cement slurries during oilwell cementing distorts their designed properties and leads ultimately to poor cement jobs. To promote best practices and enhance cementing successes, it is always desirable to understand slurry response under different conditions such as contamination. Appropriate corrective measures can then be undertaken when necessary. This study carried out complete rheological experimental characterization of oil well cement slurries contaminated by pseudo oil based muds (POBM) and treated with additives. Results show that gel strength increases with POBM contamination for all types of cement slurries. |
