Achieving cement plug success on the first attempt,
The workstring is then tripped out leaving the cement slurry to harden, thereby forming the seal. However, in horizontal wells, as the workstring is pulled through the slurry, the slurry often is pulled uphole, resulting in stringers of cement and a less-than-competent plug.On the Rheological Parameters Governing Oilwell Cement,,Cement slurry stability is a major requirement for successful oilwell cementing, especially in high angle or horizontal wells. The industry has provided different solutions for the subject always regarding the slurry response to standardized sedimentation and stabilityHow to Fill Holes in a Concrete Countertop | Concrete Exchange,With a “gel-like” consistency, this fast acting slurry can also be used to fill voids and make repairs on vertical surfaces. Slurry is a mixture of cement paste, pigment, and water. It is used to fill in the small air bubbles in the surface of the concrete.
