Squeeze cementing is basically a filtration process that occurs during the placement of the cement slurry into a wellbore entry point (casing leak, existing perforations, etc.) under sufficient differential pressure. The cement slurry is held in place until it cures and establishes a hydraulic seal. Look at this picture in Squeeze Cementing Principles explaining the […]
Workover Cementing Techniques. (1) The Injectivity test
This injectivity test page is the start of a series of posts covering cementing techniques applicable during workover, including specific job requirements, fluid characteristics, and testing procedures. We will cover each of the following job categories: Remedial cementing, well abandonment, and fluids control/shut-off. I am initiating this series of posts, (you can find links to […]
Suicide Squeeze Cementing: risky but valid
More technically, a ‘suicide squeeze’ is an application of a circulating squeeze, used in specific circumstances. In general, the cement squeeze is a fascinating topic, and an important skill to master for any experienced cementer. In a circulating squeeze, the cement slurry is ‘forced’ to flow through a lower open path and up behind the casing […]
