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.

Oxidizing Breakers Sunita offers a diverse range of breaker agents designed to effectively degrade both gelling agents and friction reducers. Through the thermal degradation of oxidizing breakers, free radicals are generated, which target the polymer backbone, cleaving it into smaller segments and thereby diminishing viscosity. This process enables the fracturing fluid’s viscosity to be lowered to levels comparable to water, facilitating a more efficient fluid return to the surface. Oxidizing breakers are available in both liquid and solid forms. Common examples include sodium and ammonium persulfate, which act as non-delayed breakers, initiating viscosity reduction at temperatures exceeding 120°F. However, an…

Foaming agents represent a crucial component in oilwell fracturing applications, serving to optimize fluid performance and enhance well productivity. These specialized additives are adept at generating stable foam, consisting of gas bubbles dispersed within a liquid phase. By entraining gas, typically nitrogen or carbon dioxide, into the fracturing fluid, foaming agents significantly reduce fluid density, effectively mitigating the risk of formation damage and improving the transport of proppants deep into the fractures. Moreover, foam exhibits superior mobility, allowing it to reach remote areas within the reservoir with ease. Foaming agents play a vital role in controlling fluid loss and maintaining…

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…
