Casing/cementing/zonal isolation
A proposed integrated workflow aims to guide prediction and mitigating solutions to reduce casing-deformation risks and improve stimulation efficiency.
This case study investigates the reasoning behind the solidification of barite behind the casing with the aim of developing solutions for efficient casing removal and the potential use of settled barite as a barrier material.
