Achieving Zonal Isolation in Challenging Formations Using Novel Scrubbing Technology and Foam Cementing
A. Malik, S. Al-Awhadi, K. Monteiro, V. Paz et autres
Abstract Achieving reliable zonal isolation in low-fracture-gradient reservoirs remains a persistent challenge across the Middle East. Elevated hydrostatic and frictional pressures during circulation and cement placement frequently induce losses into weak formations, jeopardizing annular cement coverage and long-term well integrity. Effective drilling …
