Abstract

Nowadays, efficient cementing job is a vital operation in the life of a well. Appropriate cement displacement can extend the life of the wellbore by providing long-term zonal isolation. However, cement displacement is challenging issue in horizontal wells, but achieving maximum isolation is possible by using different techniques like proper mud properties, velocity and displacement rate, centralization of casing. There are several studies has done in this filed for improving cement displacement. Practices and laboratory experiments has revealed that the casing movement can bring improvement in cement displacement; either reciprocation or rotation motion. In this research focused mainly on seven inch (7) liner rotation by using ANSYS CFX14 software. The software implement computational Fluid Dynamic (CFD) model for simulating and ensure the improvements in horizontal wells. Moreover, affect of pressure drop (P) and Equivalent Circulation Density (ECD) on pipe rotation were investigated. According to simulation result, pressure drop will increase by raising rotation speed. Further, equivalent circulation density will increase as well. Increase in this two factor leads to high efficiency in cement placement
