Analysis of Best Practices for Deepwater Cementing in Oil Based Mud (OBM) and Synthetic Based Mud (SBM)

The objectives of this project are to develop fundamental knowledge of mud-cement compatibility issues related specifically to deepwater cementing, to quantify risks associated with cementing in OBM/SBM and to develop best practices and derive recommendation in order to reduce the recognized risks. This study will analyze the relationship between temperature, pressure, cement bond, degree of mud removal and its effect on zonal isolation in complex well architecture. Fluids under laboratory investigation will include typical commercially available designs of cement slurries, SBM, OBM, and spacers with a focus on micro-particulate fluids and other new technologies. Environmental benefits of a successful project include a decrease in contamination, the formation of channels, and improved bonding of cement. Long-term wellbore integrity will be improved and environmental and safety issues such as leaks from the formation and Sustained Casing Pressure (SCP) will be mitigated. The enhanced integrity of the cement will not only save operators from costly remedial work and additional rig time, but also increase productivity as well as reduce environmental and safety risks.
