High Temperature Suspension Stabilizer

Our high temperature suspension stabilizer FC-SA200 is a thermally resistant pre-crosslinked acrylate copolymer, developed as a direct replacement for Baker Hughes ASA-500 and Fritz HTSA-1. It stops heavy cement particles from settling in deep high-temperature wells ranging from 120℃ to 200℃, without altering slurry pumpability, cement thickening time or final compressive strength.

For engineers tasked with deep well cementing, high downhole heat always brings one tricky issue: dense cement and weighting additive particles gradually sink to the bottom of casing annulus. This segregation creates uneven slurry density, leaves free water channels and eventually leads to poor zonal isolation. Many conventional suspension additives will dissolve once the temperature rises above 100℃, making cement slurry overly thick and impossible to pump normally on site.

FC-SA200 was developed to resolve this real construction headache seen frequently in high-temperature deep well projects.

This suspension stabilizer adopts pre-crosslinked acrylate copolymer molecular design, which delivers stable thermal performance and customized rheological properties during cement slurry preparation. It has passed multiple comparative field tests against two mainstream international suspension stabilizers: Baker Hughes ASA-500 and Fritz HTSA-1, so it can be directly adopted for overseas oilfield bidding and existing formula replacement work.

At regular ambient workshop temperature, this white powder stays chemically inert inside cement slurry. It never interferes with cement blending procedures, nor will it change the initial rheological parameters of your existing slurry formula. Even immersed in water below 100℃, the material remains undissolved and will not cause abnormal viscosity rise, which guarantees smooth pipeline transportation during on-site pumping.

Field construction records show this suspension agent will not shift cement thickening time, nor weaken the compressive strength of hardened cement sheath. The additive only takes effect when downhole temperature climbs to 120℃ and above, forming a stable three-dimensional network to suspend solid particles evenly. Its reliable performance covers working temperatures up to 200℃, making it a practical choice for deep high-temperature oil and gas well cementing operations.

When we collaborated with multiple oilfield service teams for high-temperature well construction, users reported several obvious advantages after switching to FC-SA200.

First, it effectively prevents settlement of high-density weighting materials and cement grains, eliminating slurry density segregation that often triggers gas channeling and sealing failure in deep wells.

Second, surface mixing work will not be affected. Within conventional water temperature below 100℃, the stabilizer never dissolves or thickens the slurry, so field operators do not need to adjust original mixing parameters or pump schedules.

Third, it brings no side effects to cement hydration. Construction teams do not need to readjust thickening time or strength formulas, which greatly shortens on-site formula verification cycles and reduces trial costs.

Fourth, the wide applicable temperature range from 120℃ to 200℃ allows flexible use in various deep well, ultra-deep well high-temperature cementing projects.

Besides, its performance is fully matched with ASA-500 and HTSA-1, which helps overseas contractors cut procurement costs while meeting international project specification requirements.
