A gas migration control additive
is a chemical that blocks gas migration through cement. This type of chemical is effective in both fresh and salt water. It helps to reduce the permeability of cement, enabling better bondage and prevent premature gelation. It can be used in all types of cement slurries. Here is a list of some of the companies that manufacture latex-based gas migration control additives. These companies offer a variety of solutions to help you control gas migration.
The main role of a gas migration control additive in cement manufacturing is to create an impermeable barrier between cement slurries. It can also reduce fluid loss during the critical hydration phase of the cement process. The latex additives that are available are designed to reduce fluid loss in cement slurries and are a cost-effective option.
Slurry B has a different transition time from non-fragile to fragile. The gel strength of Slurry B at 20, 60 and 120 minutes is depicted in Figures 6 and 7. The gel strength and shear modulus can be measured to identify gas-tight slurries. These tests can be useful for analyzing the effects of various gas migration control additives.
In order to determine gas migration properties, it is important to know the rheological properties of the cement slurry. Rheology refers to the study of the flow and deformation of fluids. The shear modulus and gel strength of a cement slurry will determine whether it can withstand gas migration.
