Advantages of the product

Superior Clay Stabilization and Shale Inhibition

Oilfield Polyamine from Feymer provides exceptional clay stabilization by adsorbing onto negatively charged clay surfaces, forming a protective layer that prevents hydration and swelling. This is crucial in water-sensitive formations where clay expansion can lead to wellbore instability, stuck pipe, and reduced permeability. Our polymer’s high charge density and molecular weight distribution ensure deep penetration into shale interlayers, effectively inhibiting dispersion and maintaining borehole integrity. Field tests in challenging shale plays have demonstrated a 30% reduction in wellbore instability issues compared to conventional inhibitors.

Enhanced Thermal and Salinity Tolerance

Feymer’s Oilfield Polyamine is engineered to withstand extreme downhole conditions, including temperatures up to 150°C and salinities exceeding 200,000 ppm TDS. Its robust chemical structure resists hydrolysis and thermal degradation, ensuring long-term stability in hostile environments. This tolerance is achieved through careful synthesis control, resulting in a polymer that maintains its viscosity and flocculation properties even after prolonged exposure. In high-temperature, high-pressure (HTHP) wells, this translates to consistent rheological performance, preventing fluid loss and maintaining cuttings transport efficiency.

Eco-Friendly and Cost-Effective Formulation

In line with global environmental regulations, Oilfield Polyamine is formulated to have low toxicity and high biodegradability, minimizing ecological impact. Unlike traditional amine-based inhibitors that may bioaccumulate, our product breaks down into harmless byproducts in natural conditions. This eco-friendly profile facilitates compliance with strict offshore drilling regulations, such as OSPAR and EPA guidelines. Additionally, the concentrated formula provides superior performance at lower dosages—typically 0.1-0.5% by weight—reducing chemical usage and logistics costs. Enhanced efficiency also shortens drilling time, leading to significant savings on rig day rates and overall project expenditure.

Frequently Questions

What is Oilfield Polyamine and how does it work in drilling fluids?

Oilfield Polyamine is a cationic water-soluble polymer used primarily as a shale inhibitor and clay stabilizer in drilling fluids. It works by adsorbing onto the surface of clay particles, forming a durable layer that prevents water from penetrating and causing swelling. This adsorption process is driven by electrostatic attraction between the positively charged amine groups and the negatively charged clay surfaces. Once the polyamine molecules attach, they create a hydrophobic barrier that drastically reduces the hydration and dispersion of clays. This action maintains wellbore stability, prevents stuck pipe, and ensures efficient cuttings transport. In contrast to simple inorganic salts like KCl, the polyamine provides a more robust and long-lasting effect even at lower concentrations.

What are the recommended dosages and application conditions for your Oilfield Polyamine?

The recommended dosage of our Oilfield Polyamine (FM-OP90) typically ranges from 0.2% to 0.5% by weight of the drilling fluid, depending on the specific formation characteristics and mud system. For highly reactive shales or in high-temperature wells, the dosage may be increased up to 1%. It is essential to conduct compatibility tests with other additives, such as viscosifiers and fluid loss control agents, to ensure optimal performance. The product can be added directly to the mud pit under moderate agitation to ensure uniform dispersion. It functions effectively in a pH range of 7 to 10 and in temperatures up to 150°C. In high-salinity environments, it maintains its inhibiting properties, although slightly higher dosages may be necessary.
