... Abstract Accurate determination of the top of cement is critical for the success of oil well cementing operations. The American Petroleum Institute (API) free water test is a standard procedure designed to assess the free water content in cement slurries. However, this study reveals significant...

... Abstract This research delves into the incorporation of red mud, a by-product of the aluminum manufacturing process, into the cementing of oil wells to bolster the sustainability efforts of the oil and gas sector. A variety of experimental techniques were utilized to mix cement slurries...

.... The proppant can then be detected using standard neutron-logging tools, at any time during the well's life. By incorporating small volumes of this detectible proppant into the cement slurry, the cement can then be detected using the same logging tools. This leads to identification of the top of cement, as well...

... is a highly complex process that depends on the in-situ condition, formation lithology, cement slurry composition, mud cake composition, drill bit type, etc. In this work, the Class-G cement slurry is cured under constant axial stress, confining pressure, and undrained conditions. This represents a field...

... industry practice to prevent fluid migration, slurry designs should be gas tight. To avoid unwanted wellbore fluids to migrate to surface, two things are required: less time to initiate migration and the lack of a flow path. With analysis of the current cement slurries, designs were unable to perform...

... and wellbore serves to create zonal isolation and provide casing support amongst other functions. There are nine types of conventional Portland cements which are ranked from Class A to J (Fink 2012). Typically, when a conventional cement slurry sets, it becomes brittle because of low tensile stress and bulk...
