DosR™ 95 Retarder
Extend the Time During Which the Cement Slurry is Pumpable
DosR™ 95 Retarder
Delay the Setting of Cement also Acts as an Accelerator Once the Slurry is in Place
DosR™ 95 is a versatile, synthetic cement retarder designed to optimize cementing operations not only delays the cement setting process but also accelerates it once the slurry is in position, minimizing transition time. Its simplified formulation helps mitigate risks such as gas migration, poor zonal isolation, and the need for costly remedial cementing.
- Retards cement setting within a temperature range of 52 °C–177 °C, with co-retarder options available for higher temperatures.
- Shortens transition time to quickly build static gel strength, significantly reducing the risk of gas migration
Performance Highlight
Cement Retarder with Built-in Acceleration, Eliminating the Need to add Gel Strength Additives
In shallow, low-temperature wells (175°F–245°F / 79°C–118°C), DosR™ 95 Retarder ensures reliable batch-to-batch performance while requiring 50% to 70% less dosage than lignosulfonate-based alternatives.
Consistence Setting Control
DosR™ 95 ensures batch-to-batch consistency and precise setting control, eliminating the unpredictability of traditional retarders.
Extended Transition Time (TT)
DosR™ 95 accelerates setting once the slurry is in place, reducing transition time, enhancing SGS development, and minimizing the risks of gas migration and remedial cementing.
Slow Compressive Strength Development
DosR™ 95 quickly achieves 500 psi compressive strength, reducing WOC time and enabling faster well turnaround, improving operational efficiency.
