Effect of Cement Contamination on Some Properties of Drilling Mud

Abstract

ABSTRACT Drilling of oil well is a capital intensive project; hence, the importance of selection of proper mud system that is free from contamination cannot be overemphasized. A poor design and contaminated drilling fluid can be very costly in the life of any well. Therefore, during drilling operations care must be taken to avoid contamination of mud with cement among others. This project details experimental work and findings associated with mud contamination with cement. Also, solutions were proffered on how to manage contaminated mud systems with cement during drilling operations. The result of this work will in no small way help not only the operators but Engineers to manage this concern with dispatch when it arises, thereby minimizing down time and associated costs which affect drilling operations negatively.
