Gas migration during the "transition time" of cement hydration is a primary cause of sustained casing pressure (SCP) and annular flow. Our Gas Control Additives are engineered to prevent gas from invading the cement slurry as it transitions from a liquid to a solid state.
By forming a tight, impermeable polymer matrix and optimizing the static gel strength (SGS) development, CT610L and CT210S effectively block gas channels, ensuring long-term zonal isolation in high-pressure gas wells.
Anti-Gas Migration: Dramatically reduces the permeability of the set cement to prevent gas flow through the matrix.
Transition Time Control: Optimizes the slurry hydration curve to pass through the critical gas-entry window rapidly.
Fluid Loss Synergy: Works in tandem with fluid loss additives to maintain a low water-loss rate ($ < 50 , mL$) under HTHP conditions.
High-Temperature Stability: Maintains chemical integrity at circulating temperatures up to 180°C.
Target Wells: Specifically recommended for high-pressure gas wells, deep exploration wells, and wells with high potential for annular flow.
Recommended Dosage: * CT610L: 2.0% – 5.0% (BWOC)
CT210S: 1.0% – 3.0% (BWOC)
Compatibility: Compatible with all API classes of cement and most common additives, including retarders and dispersants.
Preventing gas migration is not just about additives; it's about engineering the slurry's internal structure. Our CT series provides a specialized latex or synthetic polymer film that bridges pores and seals micro-channels before gas can initiate flow, protecting your well's structural integrity.

In high-pressure, high-temperature (HPHT) drilling environments, securing long-term zonal isolation is a paramount challenge. During the critical transition phase when cement slurry shifts from a liquid to a solid state, hydrostatic pressure temporarily drops, allowing destructive formations gases to invade the cement matrix. As a premier manufacturer of oilfield chemistry, we engineer cutting-edge technologies dedicated to gas control for cementing, ensuring the structural integrity and safety of challenging wells worldwide. Our specialized chemical systems are formulated to bridge the gap between slurry hydration and absolute gas blockage.
Uncontrolled gas channeling often leads to sustained casing pressure (SCP) or catastrophic blowouts. To mitigate this industry-wide risk, our comprehensive portfolio of anti-gas migration additives offers an ironclad defense mechanism. These high-performance additives work by rapidly developing a tight, impermeable polymer network or a gel structure within the cement matrix during its critical hydration window. By drastically reducing fluid loss and controlling fluid transition time, our additives effectively block gas entry paths, maintaining excellent bonding at both the casing-cement and cement-formation interfaces under extreme downhole conditions.
For operators looking for reliable oil well gas migration prevention, our products provide an all-around barrier that extends far beyond the setting phase. Whether you are dealing with shallow gas pockets or deep, highly fractured gas reservoirs, our cementing chemicals are fully customizable to match diverse slurry densities, salt concentrations, and temperature profiles up to 200°C. Investing in reliable prevention additives during the primary cementing stage saves millions of dollars in secondary remedial squeezing and mitigates long-term environmental liabilities.
Achieving flawless annular gas flow control requires a balance of fluid mechanics and tailored chemistry. Our engineered latex-based and gas-block matrix stabilizers modify the rheology of the slurry, providing a synergistic effect that maintains steady pressure control during static gel strength development.
Superior Thermal Stability: Proven performance in deepwater and HPHT oil and gas wells.
