Abstract

Setting a conventional cement plug is nearly unsuccessful when there is any wellbore flow especially for the zechstein formations. As such, the used of sodium silicate remain the common option. The silicate polymerization and gelation has been used in well formation to plug holes and reduce the catastrophic flow which cause a lot of production loses. This is usually encountered during drilling rocks zone producing large amount of water or brine. This could result in large volume of the drilling fluid lost into the formation and consequently reduce the effectiveness of the drilling operations. The total successful- ness of sodium silicate/cement squeeze depends strongly on whether the cement placed in the desired place without any contamination. Contamination from Oil Base Mud (OBM), Brine influx in the formation can affect the properties of the cement and lead to the failure of it is placement. Other factors include too low concentration of the silicate and or fresh water dilution may also contribute to some extent as tentatively drawn from a bottle test. The thesis focuses on the laboratory evaluation of the likelihood of this contaminant resulted in the sodium silicate/cement squeeze failure in Swift well. The chemistry of their interaction with the cement slurry is discussed. The zechstein brine is prepared using a programmed spread-sheet provided by Shell UK Company based on typical Molln formation as produced from a well in Germany Compressive strength, thickening time and consistency of the source contaminant were measured varying the volume of the contaminant to see their influences comparing to the neat cement and to see how the extent of these contaminations affected the cement properties. Conclusions were made base on the change of these properties observed on what potentially contribute to it is failure.
