... evaluations were conducted on both the base Class L cement and designed slurries. Class L cement slurries were first implemented for this Appalachian Basin operator in late September 2022 and have since been utilized on more than 200 casing strings as of July 2023 across multiple operators. The cement...

... above the pay zone must be isolated by a deep intermediate casing. This paper describes the process of optimizing a cement slurry that is light enough to be circulated to surface in a single stage but also has additional properties to ensure that the potential corrosive formations are properly isolated...

... When comparing the resin composite and production tail slurry, the compressive strength of the resin-composite slurry is comparable to the production tail, but Young's modulus is lower. The ratio of compressive strength to Young's modulus is often used to compare cement slurries for resiliency...

... system capable of being placed in the well adjacent to cement slurries and other water-based liquids in the fluid train. These advancements have enabled engineers to design successful remediation strategies and programs using previously unavailable techniques. This paper discusses resin chemistry...

... performances and so simplify cement slurry designs. The multifunctional additive in this study also exhibits delayed hydration, which facilitates surface mixing and generates desired high viscosity over time, minimizing settling issues in horizontal wells during placement. The innovative cement design concept...

... of the aforementioned components have on cement properties. Each component previously mentioned will be measured out at specific concentrations in the water. The water will then be used to mix a cement slurry according to API Specification 10. After the slurry is blended, a battery of tests will be run including...

... These problems include cement dehydration due to excessive fluid loss, or formation "breakdown", in which whole cement slurry is lost to a created hydraulic fracture. The engineering goal is to develop cement slurries that are low enough in density that do not exceed the hydrostatic pore pressure...

... slurry. Bulk cement and mix water temperature information is of special interest in areas of extreme temperature variation, such as the following: Surface casing applications in which cement slurry is so cold that it takes a long time to reach an acceptable compressive strength, thereby slowing...

... with a 0.4 psi/ft fracturing gradient, a single stage cementing job covering 5000 ft, would require a conventional slurry with an equivalent density of 10.0 ppg. In an effort to achieve this much annular fill in the past, many cement slurries and techniques have been attempted, including foam cement and 2...

... that fact is an abnormally low fracturing pressure in one or more of the lowermost zones. Hydrostatic head of the cement slurry must be minimized to prevent formation breakdown. Typically speaking, as the slurry density decreases by the addition of water and additives, the compressive strength also...

... cement slurry is its ability to achieve reasonable gel strength in spite of its high water content. A silicate component in the slurry efficiently ties up the excess water. Some of the other important advantages of this slurry are: 1) Ease of Blending. The new slurry is easier to blend than...

... ABSTRACT An experimental study was carried out to investigate the performance of new cement additives in controlling or eliminating gas migration through cemented wellbore annulus. The shrinkage behavior of the proposed cement slurries was obtained as a function of time and applied pressure...

... ABSTRACT A recently developed, portable cement laboratory instrument has been used to test cement consistency under actual downhole conditions. Control variables include pressure, temperature, and shear experienced by a cement slurry in the test. During a simulated temporary suspension...
