the properties of cement slurry. Polysaccharides and their derivatives are mostly
used as multifunctional additive in cement slurry. But these polymers present
number of limitations at high temperature. Polysaccharides do not reveal an
appropriate thickening of viscosity in cement slurry at high temperature which
turn gives the fluid loss, gas migration and loss of economics. It is necessary
to use such type of polymer in cement slurry that increases viscosity at high
temperature. Therefore, this study present Hydroxypropylmethylcellulose (HPMC)
polymer that is able to increase viscosity at high temperature and improve the
properties of cement slurry. Laboratory experiments were performed to determine
the characteristics of HPMC based cement slurry. The viscosity of 2 wt.% solution
of HPMC polymer was determined at various temperatures. Further 0.20-0.50 gallon
sack-1 concentration of HPMC polymer was used in cement slurry to
evaluate the API properties of HPMC based cement slurry in term of rheology,
free water, fluid loss, thickening time and compressive strength. It was observed
that HPMC polymer was stable at high temperature and increases viscosity at
elevated temperature. In cement slurries HPMC polymer resulted less than 50
mL of fluid loss; zero free water and predictable thickening time as well as
enhanced final compressive strength with some other additives. The experimental
result showed that HPMC has significantly improved the properties of cement
slurry at high temperature.]]>API RP 10B-2,200922nd Edn.,Abbas, G., S. Irawan, S. Kumar and A.A.I. Elrayah,2013787222227Brandl, A., E.P.R. Acorda, D.R. Doherty and V.
