Cement slurry fluid-loss-control additives (FLAs) - PetroWiki

Cement Fluid Loss Control Additives. Operators can confidently incorporate Al Moghera fluid loss additives into a cement system without adverse effect on thickening time or compressive strength. When using these fluid loss additives, cement homogeneity and flow are retained. Fluid loss additives also prevent formation damage by discouraging cement filtrate. Experience these other advantages of using Al Moghera fluid loss additives:

A talk about API Fluid Loss - Better Well Cementing for ALL

06/11/2016· Thinking about the fluid loss test, there is always some cement slurry loss of filtrate (water from the cement) but as the test progresses the rate of filtration reduces with time. This reduction is caused by the building of a filter cake, whose thickness depends on its own permeability. So, to answer the question, fluid loss allows to keep the water in the cement because it builds a barrier or filter cake.

Why Cement Fluid Loss Additives Are Necessary | SPE ...

To convert the total amount of fluid loss into an API fluid loss value, three parameters are needed: the permeable formation area, the mudcake thickness and its permeability. Static: A maximum acceptable value of the thickness of the cake built-up during the waiting on cement period is deduced from the annular gap. The time taken by the filter cake to completely fill up the annulus, i.e., the ...
