PAC LV

Specification of PAC LV

Application of PAC LV

KimaCell^® PAC LV is Low-viscosity Polyanionic Cellulose which can effectively reduce fluid loss without significantly increasing the viscosity of the system, especially for high-solid content systems; PAC LV has high slurry production capacity and obvious fluid loss reduction, and is especially suitable for low-solid mud and solid-free mud Phase brine slurry.

Mud fluid formulated with PAC can inhibit the dispersion and expansion of clay and shale in high-saline media, so that the wellbore contamination can be controlled. Due to the good uniformity of pac reaction, high degree of substitution, good transparency, excellent salt resistance and heat resistance, a lower fluid loss (PAC-LV) was measured according to the ocma standard.

The workover fluid prepared with PAC has low solid phase and will not block the permeability of the production layer; it can protect the production layer from permanent damage; it has the ability to clean the wellbore and reduce the workload of maintaining the wellbore; It is resistant to water and sand penetration, and rarely foams; it can be stored or transferred between wells, and the cost is lower than that of ordinary mud workover fluids.

The fracturing fluid prepared with PAC can withstand 2% potassium chloride solution (must be added when preparing fracturing fluid), and has good solubility; it is easy to use and can be prepared on site; the gelation speed is fast and the sand-carrying ability is strong; at low osmotic pressure It is used in the formation, and its fracturing effect is more excellent.
