WebPrimary cementing of casings is normally performed by injecting spacer ﬂuids, washes, and cement slurry down the well inside the casing. The drilling ﬂuid occupying the annular space behind the casing will therefore be displaced from bottom and up toward the surface, and normally with a density-stable hierarchy of ﬂuids.

Q foam decreases and density increases as the foam moves from the surface to the bottom of the casing. WebCementing the casing in place attaches it firmly to the wellbore wall and stabilizes the hole. Casing and tubing account for 15 to 20 percent of the completed cost of a well—often the greatest single item of expense on the well. Failure of casing or tubing results in expensive rework and may lead to loss of the well, or worse, loss of life. laffy taffy in carpet
