Abstract
Oil well cementing is considered one of most important operations to improve the wellbore integrity in term of blowouts, well failures and environmental disasters. Various additives have been used to improve the API properties of cement slurry to enhance the effectiveness and success of cementing operations. The aim of the study is to use Xanthan gum as a viscosifying agent in cement slurry to improve the properties of cement slurry. This work demonstrated laboratory experiment, in which rheology, thinking time and compressive strength of cement specimen were determined using Xanthan gum with other additives. The improvement in plastic viscosity, yield point and gel strength using different concentrations reveals that Xanthan gum acts as a rheology enhancer in cement slurry. Furthermore, the addition of Xanthan gum with other additives increases the thickening time of slurry and makes it pumpable at surface conditions. The compressive strength of cement specimen was 724 Psi after one day of curing. The compressive strength of the xanthan-gum based cement specimen further increased to 856 psi after 3 days of curing and to 1032psi after 7 days of curing. In is concluded that xanthan gum improves the API properties of cement slurry in terms of rheology and thickening time while provide sufficient strength that could reduce the risk of cementing operation failure.
