Hydraulic fracturing, or fracking, has become a critical technique for unlocking unconventional oil and gas reserves, particularly from low-permeability formations. The effectiveness of this process relies heavily on the properties of the fracturing fluid, a complex mixture designed to create and maintain fractures in the rock. Polyacrylamide (PAM) is a key component in many fracturing fluid formulations, acting as a vital additive to enhance performance. NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality PAM that plays a crucial role in optimizing oil and gas extraction through fracturing.

The primary function of PAM in fracturing fluids is to increase their viscosity. This thickening property is essential for several reasons. Firstly, a high-viscosity fracturing fluid is necessary to carry proppants, such as sand or ceramic particles, deep into the fractures created by the hydraulic pressure. Without sufficient viscosity, the proppants would settle out prematurely, failing to prop open the fractures and thus limiting the flow of hydrocarbons to the wellbore. PAM's long-chain polymer structure effectively traps water molecules, creating a viscous gel that provides excellent proppant suspension and transport capabilities.

Secondly, the high viscosity imparted by PAM contributes to the overall efficiency of the fracturing process. It helps to reduce friction pressure during pumping, allowing for higher injection rates with less energy consumption. Furthermore, the viscoelastic properties of PAM-based fracturing fluids can help to stabilize the fractures themselves, preventing them from closing prematurely after the pumping operation ceases. This ensures that the proppant remains in place, maintaining conductivity for hydrocarbon flow.

PAM also acts as a fluid loss reducer in fracturing fluids. Similar to its role in drilling fluids, PAM helps to form a filter cake on the fracture face, minimizing the loss of fracturing fluid into the permeable rock matrix. This conservation of fluid volume is crucial for maintaining the integrity of the fracturing treatment and ensuring that sufficient fluid remains to effectively carry the proppant and prop open the fractures.

The selection of the appropriate type of PAM is critical for optimizing fracturing fluid performance. Factors such as molecular weight, ionic charge (anionic, cationic, or nonionic), and specific formulation are tailored to the reservoir's characteristics, including temperature, salinity, and the types of rock being fractured. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of PAM products that are ideal for use as fracturing fluid polyacrylamide additives, ensuring compatibility and maximum performance.

In essence, Polyacrylamide is a cornerstone of effective hydraulic fracturing. Its ability to thicken the fracturing fluid, suspend and transport proppants, reduce friction pressure, and control fluid loss makes it an indispensable chemical for unlocking hydrocarbon reserves from tight formations. NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying the oil and gas industry with reliable, high-performance PAM, supporting advancements in extraction technologies and driving greater resource recovery.
