Applications Silicalite additive can be used as an extender for lightweight cements and a compressive-strength enhancer for low-temperature, lightweight cements. This product also imparts thixotropy to some cement slurries.
Lightweight cement can be achieved by injection of gas (foamed cement) or by adding low-specific-gravity microspheres or other enhancing additives. • Foamed cement: Injecting gas (nitrogen, compressed air, or gas-generating solids) into the slurry provides the benefit of increased slurry compressibility, increase set-cement elasticity, and
cement slurry containing a filtration-control (fluid-loss) additive in a wellbore before running the tub-ing or liner. The cement is placed by pumping it down the drillpipe and up the annulus. The drillpipe is then removed from the well, and the liner (sealed at the bottom) is lowered into the unset cement slurry. After the cement slurry sets
These additives work by way of crystalline growth or in-situ gas generation. Expansive cements expand slightly after the cement is set. This can help promote bonding integrity between cement and the casing and the formation for zonal isolation throughout the life of the well to provide the following benefits: Control gas migration

cement faces its toughest challenge under ground—in oil and gas wells where envi- ronmental conditions are far more severe than any encountered on the earth's surface. This artic e outlines the chemistry of port- land cement, the variety used to cement casings in wells and provide zona isolation, and explains how additives faci itate cement

Methods of using density-reducing additives comprising low-density particulates in subterranean cementing operations are provided. In one embodiment, the present invention provides a method of cementing comprising: providing a cement composition comprising a cement component, a base fluid, and a density-reducing additive comprising particulates that comprise an agglomerating material;
A Heavyweight cement additive can be any material that has a higher density that that of the base cement slurry, allows the slurry to remain stable with less mix water, or both. There are several additives that are classified as actual Heavyweight additives, but many others that allow us to increase the slurry density through other means.
Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.
