Cementing additives can be considered to be workover and completion chemicals as well, because this process is part of the completion process of the well. During this process a pipe is placed down the hole and cement is pumped around the outside of the pipe. This is to prevent the transfer of fluids or gases within wellbore zones.
The cement is also necessary to protect the casing from collapsing, the effects of drilling, and corrosion allowing field personnel to have better control of the well. Due to the depth of the well and other geologic factors, chemicals must be added to enhance setting times and make adjustments for porosity and other characteristics of the cement, which may not be compatible with the surrounding geology.
Here at Croda we recognise that every well has its own set of downhole characteristics and that understanding this is key to successful completion systems. Cementing a well to a high standard is a vital part of ensuring that high quality production processes are attained. As part of this process we provide surfactants to overcome challenging conditions. Investigate the different products we have to offer for well completion processes.
Used to protect workover equipment and tubulars from carbon dioxide, oxygen and hydrogen sulfide corrosion. Our range offers both oil and water-soluble products.
Used throughout completion processes to prevent or break foam. We offer a broad range of polymeric surfactants which provide significant reduction of foam and excellent product stability in a wide range of conditions.
Helps to reduce the viscosity of the slurry.
Our solvent/polymer blends demonstrate superior performance to prevent the build-up and precipitation of paraffin wax.
Used to bring debris to the surface of the well, whether it is gas, oil, or an injection well. Our products help to control the flow of completion fluids providing stability over a broad range of temperatures and shear.
Surfactant additives used to help change the oil-to-water ratio. By reducing the surface tension of liquids our wetting agents are proven to allow for improved spreading and superior wetting of solids.
