The effectiveness of hydraulic fracturing in oil and gas recovery hinges on the precise placement of proppants, typically sand, within the created fractures. This critical task relies heavily on the rheological properties of the fracturing fluid, particularly its ability to suspend and transport these granular materials. NINGBO INNO PHARMCHEM CO.,LTD. presents an advanced solution in the form of its integrated multi-supramolecular emulsion, engineered to deliver exceptional sand suspension and carrying capabilities through its unique viscoelastic structure.

At the heart of this performance is the fluid's strong suspension capacity. The multi-supramolecular emulsion, when diluted, forms a special spatial network viscoelastic structure. This structure provides a framework that can effectively hold and transport sand particles, preventing them from settling out of the fluid column. With a viscosity exceeding 40mPa.s, this fluid is capable of supporting a significant concentration of proppants, a crucial factor for achieving effective fracture conductivity. This ability is vital for ensuring that the proppant is delivered precisely where it is needed to keep the fractures open after the fracturing treatment is complete.

The viscoelastic nature of the fluid also contributes to its good friction reduction performance. While maintaining the necessary viscosity for sand carrying, the fluid exhibits low viscosity and viscoelastic sand carrying at low concentrations (0.05-0.3%). This balance allows for a resistance reduction rate of 75-85%. This means that less energy is required to pump the fluid downhole, reducing operational costs and equipment strain. The term 'slippery water' often refers to fluids with excellent friction reduction, and this formulation serves effectively in that capacity while also providing superior sand carrying capabilities, a combination often difficult to achieve.

The successful suspension of sand is not merely about viscosity; it's about the fluid's ability to provide both viscous drag and elastic resistance to the settling proppants. The supramolecular network within the emulsion provides this precise balance. This is further supported by the additive's efficient instant dissolution, which allows for immediate on-line preparation and application, ensuring the fluid's properties are optimized just before injection. This rapid preparation minimizes variability and maximizes effectiveness.

The implications of superior sand suspension and carrying capacity for oilfield operations are substantial. It leads to more uniform proppant distribution within the fractures, which in turn ensures better inter-connectivity of the reservoir and higher sustained production rates. Moreover, the low damage nature of the fluid, with a core damage rate less than 20%, means that the enhanced conductivity achieved through effective sand placement is not compromised by the fracturing fluid itself. The fluid is also cross-linkable, allowing for higher proppant loading (over 20% sand) when needed, and it is easily broken post-treatment for efficient well cleanup.

The temperature adaptability (0-180°C) and the environmental friendliness, including the capacity for produced water reuse, further cement this product's value. By partnering with NINGBO INNO PHARMCHEM CO.,LTD., operators can leverage these advanced viscoelastic properties to optimize their hydraulic fracturing treatments, ensuring efficient proppant placement and maximizing hydrocarbon recovery.
