In multistage horizontal wells, cemented completions provide zonal isol ation during the hydraulic fracturing treatment. With the tendency to dril l longer laterals and to shorten the distance between stages, cementing fa ces new technical challenges in cement slurry placement and zonal isolatio n. One of the challenges involves incomplete displacement of drilling flui d from the annulus, thus creating communication pathways behind the casing and potentially uncontrolled fluid flow during a hydraulic fracturing tre atment. In addition, many horizontal sections are now being drilled with n on-aqueous fluids (NAF&rsquo\;s), making the displacement process even mor e complex, due to the hydrophobic nature of those fluids.
This pres entation will describe a new technology that addresses the incomplete mud removal challenge. This technology provides zonal isolation even for the s ections with poor mud removal.  \;The new cement system interacts with residual NAF and changes its properties without affecting the cement pump ing operation. New laboratory techniques for studying residual drilling fl uid properties and zonal isolation will also be discussed. Field cases dem onstrating the efficiency and versatility of the cement system are also in cluded.
