Perhaps the most critical component of the drilling process to the integrity and longevity of a geothermal well is the cementation of the casings. API class G cement is usually utilized for cementation of geothermal well in India, and additives are used to improve the properties of the cement slurry. The primary aim of cementation of geothermal well is to withstand the well in presence of geothermal fluids and high temperature. The objective of the study is to investigate the effect of cement slurry consistency using hydroxyl ethyl cellulose. This paper includes various aspects of geothermal well cementing and cement slurry design for case study of Dholera geothermal field. Hydroxyethyl cellulose is used as multifunctional additives for getting desired properties of the cement slurry for Dholera geothermal field.
