Temperature Impact on AMPS and AHPS Polymer Performance in Oil Well Cement

Two synthetic polymers were tested for temperature stability between 100 and 220°C under 35 bar pressure, simulating oil well cementing conditions. The study, authored by Constantin Tiemeyer of the Technical University of Munich, assessed fluid loss performance via high-pressure filtration tests and polymer conformation via dynamic light scattering. The AMPS-based polymer showed reduced performance due to chain shrinkage, while the AHPS-based additive maintained stable fluid loss control.

Use Cases

• Predicting polymer performance degradation based on high-temperature aging data mentioned in the description
• Modeling the relationship between hydrodynamic radius and adsorption capacity for fluid loss additives
• Comparing the thermal stability of different copolymer formulations for cementing applications

Strengths

• Experimental data covers a specific high-temperature range of 100–220°C
• Tests were conducted under simulated downhole pressure conditions of 35 bar
• Analysis includes multiple performance metrics: fluid loss, water retention, and adsorption

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
