... Abstract In the completion of oil and gas wells, successful cementing operations essentially require the complete removal of the drilling mud and its substitution by the cement slurry. Therefore, the displacement of one fluid by another one is a crucial task that should be designed...

... is the quality of the cementing job. As in conventional cementing operations, cement plug setting requires an efficient fluid displacement process to be considered "successful." Due to the nature of the operation, i.e., displacing one fluid with another inside a tubular, mixing of the fluids during this process...

... Abstract Displacing fluids in downhole conditions and for long distances is a complex task, affecting several steps on well construction. Cementing gains relevance in the moment that fluid contamination compromises cement sheath integrity and consequently zonal isolation. Density and rheology...

This paper presents an approach using the explicit finite element method to model the static and dynamic interactions between the bit, the reamer and the formation of the BHA. The results for axial displacement...
