... and other industries, has not yet been fully implemented in oil and gas well cementing. Industrial waste materials, such as Class F fly ash (FFA), can be utilized to improve cement properties or create new cement binders. Hematite is used as a weighting agent to increase cement slurry density. However...

... Abstract Foamed cement was successfully used in the riserless section of an ultradeepwater well located in 11,900ft water depth. Foamed cement was selected to minimize operating costs and provide flexibility to adjust slurry density on a short notice. The seawater column exerted 5,319.1-psi...

... strings in the Permian Basin. To evaluate geopolymer cementing for oil and gas well construction, a field example project was divided into four phases: development of robust slurry design in the laboratory, confirmation of compatibility with oilfield equipment, scalability for safe execution in the field...

..., and uniaxial compressive strength. The use of sucrose, Zn species, K species, and Al2O3 was inspired from results presented in previous studies. The slurries were tested under a bottomhole circulating temperature 50° and a static temperature and pressure of 70° and 14 MPa respectively. The results indicate...

... Abstract The detection of asphaltene precipitation and gas hydrate formation is critical to preventing production losses and to optimize strategies for mitigation and remediation. Likewise, the evaluation of some flow properties (e.g., viscosity and yield stress) of the slurries formed...

... of reducing Waiting on Cement (WOC) time during cementing operations in oil and gas wells. A rigorous process was executed to select the most promising particles and several experiments testing different cement slurries designs were executed to confirm the feasibility of this patented technology. Magnetite...

... it to the surface to isolate the production path from the corrosive formation fluids. Thus, well integrity is regained, and corrosion to the well casing is prevented. To achieve long-term zonal isolation in corrosive environments, various slurry systems were studied, and a resin-blended cement system was selected...

... loss additive overcomes shelf-life stability and fluid transfer issues inherent to conventional oil-based suspension additives, while providing excellent fluid loss control in cement. Shelf- life stability and fluid transfer rates affect the quality of mixing cement slurry, reduce delivery/pump rates...
