Improve cement bond logs and maximize zonal isolation
At the technical limits of drilling fluid removal, cement bond quality and hydraulic isolation can be compromised by leaving channels behind the casing. This is particularly problematic in wells where differential pressures may promote interzonal fluid communication.
To avoid these problems, the CemFIT Shield system interacts with any remaining NAF to reduce its mobility and the likelihood of communication along channels.
Use conventional equipment and designs
CemFIT Shield system is compatible with conventional cements, additives, equipment, and designs, enabling simple blending, mixing, and pumping for most field applications. It can be designed for densities from 12 to 18 lbm/galUS [1.44 to 2.16 g/cm3] and temperatures up to 340 degF [171 degC].
