Improvement of Cement Placement in Horizontal Wells by Liner Rotation Using CFD

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 possib...

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.

In this research focused mainly on seven inch (7) liner rotation by using ANSYS CFX14 software.
