In oil and gas well construction, one of the most critical processes is primary well cementing, which is the process of placing cement in the annular space between the casing and formations exposed to the drilled wellbore.The major function is to provide zonal isolation between the formations, with the objective of preventing oil and gas from contaminating ground waters or to exclude fluids such as water or gas from oil producing zones in the well.For this reason, one of the needs in well cementing is the use of materials with high performance that enhance the longevity of the well and reduce costs associated with repair or losses due to failures in the cement sheath.Nanotechnology offers a means to obtain substantial changes in the chemical,physical and mechanical properties, due to the increase of their surface that allows them to have a high reactivity.
