Gelling Agent
Innovative Polymer Chemistry for Challenging Stimulation Process
Gelling Agent
Strategic Molecular Design for Frac Fluid Viscosifying Agents
As the exploration of oil and gas reserves pushes into increasingly harsh environments, conventional fracturing fluids are encountering significant limitations. High-temperature, high-pressure, and deep formation conditions demand innovative solutions that go beyond the capabilities of traditional methods.
The DosORO™ synthetic polymer/GG blended system is a versatile solution that adapts to various operational needs. In some scenarios, it serves as a direct alternative to traditional DosORO™ GG fluids, maintaining performance while reducing costs. In others, it acts as an efficiency-boosting option, enhancing the overall effectiveness of the fracturing process.
Design Flow of Stimulation Fluid System
Boost Pump Efficiency by Synergistic Additives
Viscosifying Agent
Improve fluid rheological properties by providing sufficient viscosity.
Crosslinking Agent
Connects the polymer to form a 3D network structure by chemical bonds.
Breaker
Break the fluid into a thin liquid and finally flows back to the surface.
Guar Gum and Its Derivatives
Extended Molecular Chain
By increasing the number of hydration groups on the molecular chains, DosORO™ GG not only minimizes residue after gel breaking but also significantly improves water solubility. This enhancement allows the polymer chains to stretch and wind effectively in water, delivering a robust thickening effect. Complex groups are introduced into the DosORO™ GG chain to extend the molecular chains, reduce entanglement, and increase the crosslinking ability, further enhancing the temperature resistance of the biopolymer.
Thermoviscosifying polymer
Hydrophobic and Hydrophilic Fusion
DosORO™ polymer gelling agent structure is designed with lone electron pairs that act as crosslinking points, enabling complexation reactions that form a high-temperature-resistant crosslinked gelling agent. The presence of strong hydrophilic groups enhances water solubility by forming intermolecular hydrogen bonds, further improving the overall performance of the polymer. The inclusion of hydrophobic monomers in the molecular chain significantly boosts the polymer's rheological properties, enhancing the effectiveness of DosORO™ through modified intermolecular associations.
Acid Gelling Agent
Thickener Efficiency in Acid Stimulation
DosORO™ AG is an efficient viscosity builder and has good stability in 15% HCl at temperatures up to 150°F. Computer model studies, which take into consideration cool-down and gel degradation rate at various stages of acid spending, indicate viscosity is maintained when treating wells that have bottomhole temperatures (BHT's) up to 220°F. Since the gelled acid retains its viscosity during spending, both reaction rate and fluid leakoff are retarded.
Gel Stabilizer for Fracturing Fluids
GeliN™ sulfur-free gel stabilizer is designed to improve the stability of fracturing fluids, ensuring optimal performance even under high-temperature conditions. Unlike conventional stabilizers that contain sulfur, our product is non-hazardous, biodegradable, and provides superior stability
