Field-proven oilfield chemical solutions spanning acidizing, fracturing, profile control, gathering, and production treatment -- deployed across Bohai Sea, Middle East, Xinjiang, Daqing, Sichuan, and South China Sea operations.
A comprehensive portfolio of stimulation chemicals engineered for high-temperature, high-salinity, and ultra-deep well conditions. Products include instant-dissolving thickeners, emulsion gelled acids, corrosion inhibitors rated to 180°C, VES diverting agents, autogenic acid systems, and specialized acid additives.
Developed using supermolecular pre-construction technology, this powder creates nanometer-scale water transport channels inside dry particles. Unlike conventional polymers that require large maturation tanks and dissolve slowly, this product achieves full dissolution in 1-3 minutes via an "internal disintegration" mechanism rather than surface gelation. Salt resistance is achieved through hydrophobic association interactions that actually strengthen under high-salinity conditions.
Prepared through reverse emulsion polymerization, this gelled acid system eliminates the cumbersome separation and purification processes required by conventional powder thickeners. The emulsion thickener enables online continuous construction, can be directly added to sand-mixing trucks, and achieves rapid viscosity buildup with excellent viscoelastic properties. Evaluated per standard SY/T 6214-2016.
Developed using Materials Studio quantum chemistry calculations and molecular dynamics simulation to design corrosion inhibitor molecules from the molecular level. The "anti-temperature monomer + strong adsorption capacity" design philosophy produces inhibitors that meet petroleum industry first-class standards (SY/T) at temperatures from 90°C to 180°C. Targeting ultra-deep wells at 6,200-7,000m depth.
A viscoelastic surfactant (VES) that addresses uneven acid distribution in heterogeneous carbonate reservoirs. As acid reacts with rock, rising pH and calcium ion concentration cause VES molecules to self-assemble from spherical micelles into worm-like micelles, creating a three-dimensional network that temporarily plugs high-permeability zones and diverts acid to low-permeability areas. Evaluated per standard Q/SH CG0150-2021.
An acid system that is non-acidic or weakly acidic at surface conditions but gradually generates acid at bottomhole temperature. This fundamentally solves the problems of conventional acids: overly fast reaction rates, limited penetration distance, and severe equipment corrosion. The acid-generating mechanism is based on nucleophilic substitution reactions of anhydrides, esters, and halides that hydrolyze under downhole heat.
A comprehensive suite of acid additives formulated for post-acidization reservoir protection. Iron ion stabilizers prevent Fe(OH)3 precipitation when residual acid pH exceeds 2.2. Demulsifiers break stubborn emulsions formed during fracturing flowback. Drainage aids reduce interfacial tension to accelerate residual fluid recovery. Evaluated per SY/T 6571-2012 and SY/T 5886-2018 standards.
Advanced technologies for CO2 flooding anti-channeling, horizontal well water shutoff, nano-imbibition enhanced oil recovery, gas well water lock release, and foam drainage. Designed to address the industry's most challenging conformance and recovery problems in mature and unconventional reservoirs.
A composite channeling prevention technology combining CO2-responsive gel with CO2 acid-resistant foam. The CO2-responsive polymer forms a three-dimensional network structure in CO2 environments, while the enhancer releases crosslinkers to form high-strength gel. The acid-resistant foam uses amphiphilic surfactants that become positively charged under CO2 conditions, forming dense interfacial films for stable foam generation.
A three-slug composite water plugging system using degradable temporary plugging gel (pressure cone), in-situ viscous hydrogel (main barrier), and organic-inorganic dual-network strong gel (sealing plug). The system achieves selective water shutoff while maintaining oil flow. Gel strength exceeds G' > 10 Pa (strong gel category per SY/T 6296-2013), with plugging rates >96% on high-permeability cores.
Modified nano-SiO2 particles using silane coupling agent (KH590) surface treatment that solve natural nanoparticle agglomeration problems. The particles match reservoir micro-nanoscale pore throats for deep penetration into spaces that conventional agents cannot reach. Achieves ultra-low interfacial tension (1×10&supmin;³ mN/m) and strong wetting reversal ability.
A foam drainage system based on KN71C surfactant with foam stabilizer AS and synergist KNHF. The KN71C molecule combines high surface activity with low-molecular polymer thickening characteristics, enabling easy foam formation with high liquid-film viscosity and toughness. The system maintains excellent performance in high temperature, high salinity, and high condensate oil environments.
Pipeline protection and flow assurance chemicals covering drag reduction, corrosion inhibition, asphaltene control, wax prevention, pour point depression, composite de-blocking, heavy oil viscosity reduction, and sulfur removal. Proven across 5,000+ km of pipeline operations.
Composite drag reducers that act on the elastic buffer layer of turbulent flow to absorb turbulent energy, prevent fluid molecules from entering the turbulent core area, and reduce energy dissipation. Composed of multiple surfactants with strong dissolving ability for wax, colloid, and asphaltene. Soluble in both water and crude oil.
Corrosion inhibitors based on tung oil rosin imidazoline Mannich base chemistry. When compounded with tallow propylenediamine and thiourea, the agent forms a microemulsion that disperses uniformly and creates a complete, dense, multi-layer spatial network adsorption film on metal surfaces. Four product variants cover pre-filming, H2S environments, CO2 environments, and wastewater systems.
Addresses asphaltene precipitation during CO2 flooding and pressure depletion that causes wellbore and pipeline blockage. Static testing (dispersion-precipitation method) achieves 86.8% inhibition rate at 200 ppm; dynamic testing (high-temperature high-pressure reactor) achieves 80.3% inhibition. Temperature resistance validated to 120°C with inhibition rates exceeding 80%.
Long carbon chain molecules interact with high-carbon wax through supermolecular forces to inhibit wax precipitation, crystal growth, aggregation, and deposition. The mechanism involves eutectic adsorption that modifies wax crystal structure, surface adsorption that disperses crystals, and suspended dispersion that prevents deposition. Evaluated per SY/T 6300-2024.
Comprehensive production chemistry solutions including natural gas desulfurization agents, crude oil desulfurizers, wastewater desulfurizers, demulsifiers, heavy oil viscosity reducers, composite wax removers, and sulfur removal agents for safe and compliant production operations.
Composite viscosity reducers carrying oil-soluble emulsified droplets in aqueous solution. On contact with heavy oil at bottomhole temperature, the emulsion breaks and the oil-soluble agent interacts with heavy oil components to reduce viscosity. The separated water forms "water-jacket oil-core" or suspended oil structures -- a transitional emulsion system with very low viscosity enabling efficient heavy oil production.
Based on triazine chemistry where alternating nitrogen and carbon atoms create electrophilic sites that react rapidly and selectively with H2S and other nucleophiles. The nitrogen atoms' electron-withdrawing induction effect drives efficient desulfurization at low cost, controlling corrosion across single-well production, oil/gas processing, and gathering pipeline equipment.
Unlike conventional wax removers that rely solely on dissolution (which fails on high-carbon paraffins), this product uses a novel dispersion mechanism. Molecules penetrate between wax molecules, destroy inter-molecular forces, and disperse wax into ~10 micrometer particles that are suspended and carried away by solvent. Achieves >90% dispersion of high-carbon paraffin wax.
Complete desulfurization solutions including amine-based natural gas sweetening agents (absorption-regeneration closed loop), crude oil desulfurizers, and wastewater desulfurization systems. The amine scrubbing process uses absorption and regeneration towers with heat exchange, separation, and auxiliary equipment for continuous H2S removal from gas streams, ensuring safe and compliant production.
