A terpolymer comprised of sodium styrene sulfonate SSS, fumaric acid FA, and acrylamide AM was synthesized by aqueous free radical copolymerization and evaluated as fluid loss additive for oil well cement. The chemical structure and performance of the terpolymer were characterized by Fourier transform infrared FTIR spectroscopy and thermal gravimetric analysis TGA the molecular
Additives are chemicals and materials blended into base cement slurries to alter the performance of the cement. Due to the inherent nature of base cements Neat, Portland and Pozzolanic and because of the demands placed on the cement sheath throughout the life of the well, the performance properties of the cementing slurry are modified to address the specific and unique conditions of each well.
Oilwell cements are used for oilwell grouting, sometimes called oilwell cementing. They consist of either portland or blended cements, plus additives. Oilwell cement must be slowsetting and able to withstand the high temperatures and pressures of these deep wells. The process plays a significant role in welldrilling operations.
KLAGARD shale stabilizer and inhibitor system reduces the swelling of sensitive shales and drill cuttings exposed to waterbased drilling inhibits shale hydration, reduces the effect of drill solids on viscosity, and works to minimize problems such as

The table also includes an indication of the primary uses and benefits, along with the cements that they can be used with. The primary effects of the cement admixtures on the physical properties of the cement, either as a slurry or set, are presented in Table 2. This is a quick reference, and individual additives in a given category may not agree in total with the effects as given.
The high costs associated with drilling and completing new oil and gas wells force the industry to use the best possible technologies to increase success rates and reduce job time. Clariant39s leadingedge specialty additives for drilling, cementing, completion and stimulation are designed to deliver realtime results for maximum productivity
It is a polymeric additive designed especially to cement at high temperature 204C and to carry out right angle closing. Same is a requirement to design gas well slurries and. This product makes the slurry be slightly viscous and it does not modify recommendation 0.3 to 0.8.
land cement, the variety used to cement casings in wells and provide zona isolation, and explains how additives faci itate cement placement and ensure stability after setting.l Rudimentary cementing of oil wells began at the turn of the century when few wel s went deeper than 2,000 feet 610 meters. Cementing operations were usually per

There are following 10 types of additives of cementing accelerator, retarder, defoaming agent, drag reduction agent dispersant, fluid loss additives, antigas migration agent
effective cement slurries by adding additives to enhance or modify to achieve desired cement properties 2. The additives added in cement are an integral part of the well design, construction and integrity. Therefore, a through lab testing must be carried for any new cement design or additive before applied the cement slurry in the field.
Oil well cement must also be designed and tested to perform with specific admixtures that are added to the slurry mix in order to achieve the desired thickening timeand rheology. The four most commonly used well cement types are Class A,Class C, Class G, and Class H.
