Cementing products are used to support and protect well casings and the assist in isolating zones. To achieve the safest, most profitable wells, and maintaining environmentally safe zonal isolation, using the cementing process in the wellbore is key to its creation and maintenance.
Although cement-based overlays have been around for decades, many of today's systems blend polymer resins with cement, sand, and other additives to improve performance, wear resistance, and aesthetic qualities. Polymer-modified overlays can be applied in layers as thin as a credit card or up to several inches thick without delamination or failure.
SNF's years of experience in the creation, manufacturing, and supply of polymers to the oil and gas industry has led to the development of a series of polymers specifically designed for cementing applications. Different additives are often needed as drilling operations go deeper into the formation. • Reduce fluid loss • Stabilize shale ...
Cement compositions. Polymers have been used as fluid loss control additives in cementing operations. These include HEC and carboxymethylhydroxyethyl cellulose, copolymers of AMPS and AAm or N,N-dimethylacrylamide, and lignin or lignite grafted with AMPS, acrylonitrile, and N,N-dimethylacrylamide.

Cement evaluation logs and other cased-hole logs can indicate the strength of the set cement and whether it "s bonded to the cas.ng (far right). The out- come of a cementing job, however, depends ultimately on choosing the appropriate cement and additives to cope with particu lar well conditions. . Portland cement was developed by Joseph Aspdin
Our water soluble polymers provide a host of benefits and functionality in a wide range of applications. Water soluble polymers from Gantrade complement product offerings in the coatings, adhesives, sealants and grouts markets, and in other arenas that include oil field chemicals, cement additives, construction materials, and consumer products.
ABSTRACT: Polymer modification of cement paste increases the tensile and flexural strength of mortars and concrete and reduces their brittle nature. Since the polymer-modified cement is a composite of two entirely different types of materials, the characteristics of the key components, cement and polymer, will be briefly described.
This is a nonionic polymer that is typically used as a fluid-loss enhancer in conjunction with sodium naphthalene sulfonate condensed with formaldehyde (SNFC) to improve the performance of other polymers. When used alone, PVP is not very effective as an Fluid-Loss Control Agents (FLA). However, when PVP is used in conjunction with SNFC, the ...
Jan 24, 2019· The other major application is the production of high-strength concrete at w/c's ranging from 0.3 to 0.4. It has been found that for most types of cement, superplasticizer improves the workability of concrete. One problem associated with using a high range water reducer in concrete is slump loss.

Cement shrinkage during setting is regarded as one of the main causes behind formation of microannulus cracks. In this paper, a new class of polymer-based expandable additives is presented in the form of fibers to address shrinkage and debonding issues in the subsurface. The proposed fiber additives are made from shape memory polymers.

One category is additives and the other is bonding agents. They work towards the same goal, but they do it very differently. Additives are chemicals or compounds such as rubber, vinyls, acrylics and different polymers that are sometimes added to portland cement mixtures. All they do is simply make the concrete mixture stickier.
