Lab testing is an essential part in the cementing process. It is needed to ensure the pumping of a safe and reliable cement slurry with the required cement properties to last the life of a well. Testing ensures the slurry meets specifications for mixing, density, pumping times and compressive strength development at downhole conditions. Quality control analysis of dry cement blends also ensures a stable slurry for use and can flag up issues with the blend.
SGS can help you ensure that your cement meets the required specifications so you can avoid operational delays, including increases in rig time, and ensure the integrity of your well throughout its lifetime.
Through our laboratory expertise and custom technologies provided at our in-house cementing services lab, we can provide a range of services, from quality control through mixing and testing, including thickening time analysis and compressive strength development using ultrasonic cement analyzers.
