- Petrochem - Extender Powder & Liquid (P-EXT & P-EXTL) is a powdered and liquid cement extender that allows larger quantities of mixed water to be added to the slurry, but doesn’t cause excessive water separation. Here are some solid reasons why this cement additive is useful within the oilfield industry:
- Adding 3% more of P-EXT can increase the yield of a sack of cement by 250% according to Petrochem’s research on our data tables.
- These cement slurry volume calculations prove to show that additional products of cement slurries make businesses more lucrative by cutting costs
- Produces additional cement from one slurry - added resources for oil field business owners and cementing companies
- Accelerates the strength development of cement
- Finds weak formations within the cement and strengthens them
- Because P-EXT slurries contain large amounts of water, compatibility issues can make other additives mixed with this additive; less effective. Please consult with Petrochem laboratories if you are planning on mixing additives with an oil and gas cement extender.
- Recommended concentrations mainly depend on the working time. With shorts jobs where separation would be an issue, the higher concentration would be advised to add to the cement slurry. For situations where the slurry is pumped in plug-flow or when slurries circulate to the surface; lower concentrations of cement extenders are recommended.
How do Cement Extenders Work?
A cement extender is a chemical additive used to increase the volume of the slurry or can be used to decrease the density of the cement. The additive is mixed into the cement slurry and finds the free water within the mix. The faster the water gets absorbed the faster the cement will be curated. Extenders also increase a normal batch of cement which typically be what your business producing a bigger yield of cement with a faster cursing time.
Why do we use Cement Extenders?
Many business owners constantly have short jobs that need quick turnarounds within the project. Speeding up the thickening time also allows the extenders to find weak formations within the concrete thus also offering better compression strength for cement slurries. Extenders also increase the yield and volume of the cement slurries; so many business owners understand that an increase in product means you can produce more with less cost.
Advantages and Disadvantages of using Cement Extenders?
There are many advantages to using cement extenders. Cement extenders can be used to decrease the density of the slurry. Cement extenders can also improve the durability of the concrete once it is hardened. One of the disadvantages is that some extenders are not compatible with other additives.

At Petrochem, our cement extenders were created to save time with a faster thickening time for cement slurries. The additive is combined within the slurries, finds the free water, and strengthens the compression of the overall concrete. Our extenders also can find weaknesses within the curated cement and strengthen those components.
