Kemira Oyj : Control inorganic scale to maintain production flow

The stimulation of shale reservoirs by hydraulic fracturing uses large quantities of water to make up the frac fluids. The water composition used in the frac package can vary from freshwater, to produced water, or a combination of both depending on availability or local regulations.

As the water comes in contact with the reservoir during fracturing, minerals can be dissolved from the shale forming scale in the reservoir and well, either during the frac or after the well is returned to production. The re-use of produced water can intensify the problem, re-introducing high levels of minerals with the frac fluid and potentially impacting performance.
The deposition of inorganic scales including sulphate and carbonates can reduce conductivity, damage the reservoir and ultimately impact hydrocarbon recovery, diminishing the return on investment for the frac job.

Designed to extend the life of your well

Kemira KemGuard® scale inhibitors are designed to prevent scale deposition in hydraulically fractured wells, thereby minimizing production risk and extending well operating life. Our polyacrylate and sulphonated co-polymer chemistries are specifically designed to control common oilfield scales such as carbonates and sulphate and are compatible with our KemFlow friction reducers.

Our R&D and applications experts are supporting customers with a tailored scale inhibitor selection based on their unique field conditions and brine composition. We ensure our products provide effective scale control and are compatible with your frac fluids.

Our chemical solutions ensure continued flow and extend the lifetime of your well.
