Fracturing

Achieving the correct placement of proppants in hydraulic fracturing relies heavily upon the gelling agents which largely contribute to fracturing fluid viscosity for precise proppant transport. This creates good rheology for matrix stimulation treatments with efficient plugging of the surface and flow strings to eliminate lost circulation in the thief zones. Sunita USA provides tailored high performance gelling solutions for your well stimulation needs and successful fracturing operations. The Problem: Poor Fracture Efficiency Without Proper Gel Support Unstable or lower viscosity fracturing fluids tend to create more complex fractures in hydraulic fracturing, which leads to inefficient proppant placement, fluid loss…

Oil and gas professionals battling clay induced formation damage need reliable solutions. Sunita Hydrocolloids USA’s clay stabilizer delivers superior protection against swelling and migration. This ensures optimal permeability and long term well productivity. Engineered for both shale and sandstone formations, our clay stabilizers minimize fine migration. They also preserve fracture conductivity. This crucial action helps maintain consistent hydrocarbon flow. The Critical Role of Clay Stabilizers in Hydraulic Fracturing Clay induced formation damage poses significant threats. Clay swelling reduces crucial permeability, sometimes by up to 70%. Furthermore, fines migration severely damages proppant packs and compromises fracture networks. These issues often lead…

Biocides are essential in oilfield operations to safeguard stimulation or drilling fluids from bacterial contamination and to prevent bacterial invasion into the reservoir. Bacteria can degrade the polymers used in stimulation fluids, reducing their viscosity and friction-reducing abilities. Contamination of reservoirs by bacteria introduced through stimulation fluids can lead to souring. Glutaraldehyde is effective against sulfate-reducing bacteria and provides long-term protection, while quaternary ammonium-based biocides offer rapid elimination but have a shorter lifespan. Sunita provides reliable Biocides for drilling and stimulation, including Glutaraldehyde, DDAC (didecyl dimethyl ammonium chloride), and blends of Glutaraldehyde with quaternary ammonium-based compounds.

Struggling with slow flowback or formation damage? Every fracturing operation faces a critical challenge: efficiently breaking down viscous gels after stimulation to restore optimal well productivity as slow or incomplete degradation leads to costly formation damage, delayed production and lost revenue. Sunita Hydrocolloids' high-performance fracturing gel breakers solve this problem with precision-engineered chemistry that ensures rapid viscosity reduction and minimizing flowback time. Our ultra low residue formulation protects reservoir permeability and custom activation is designed for each well’s temperature, pH and fluid system. The Critical Role of Breakers in Hydraulic Fracturing Hydraulic fracturing fluids rely on polymers like guar gum…

Foaming agents are essential additives that enhance fluid mobility, reduce friction and improve proppant transport in hydraulic fracturing and gas well deliquification. Their ability to stabilize gas-liquid foams ensures efficient operations, preventing premature breakdown and maintaining well productivity. Whether the goal is to lift liquids from low-pressure wells or boost production in tight formations, the right foam chemistry makes all the difference. Sunita Hydrocolloids leads the way in high-performance, adaptable foaming solutions designed for demanding oilfield conditions. Our formulations adapt to varying salinity, temperature and pressure profiles, giving engineers the flexibility to optimize results across diverse well environments.  The Problem:…

Surface-active agents, commonly referred to as surfactants, are chemical compounds that operate at the interface of immiscible phases. Within fracturing applications, surfactants play a pivotal role in mediating interactions between oil and water interfaces, whether within the stimulation fluid itself or between the stimulation fluid, the formation, and/or the formation fluids. Optimizing the surface tension, contact angle, and interfacial tension of fluids improves the performance of stimulation fluids in several areas. These surfactants function as wetting agents, flowback aids, fluid recovery agents, and dispersing agents, among other crucial roles. Surface tension reducers are meticulously crafted surfactants designed to significantly diminish…
