PF-NETLOCK: Strong network plugging agent
Overview：
PF-NETLOCK is an auxiliary series of products to improve plugging efficiency for serious lost circulation, with compressible and high resiliency network plugging structure. The product will form a perfect ""filter net"" after entering the fracture. The captured bridging particles are then gathered together to form a whole plugging layer quickly, thus filling the fracture effectively.
Characteristics：
High resilience；Hollow porous；Reduce the permeability of plugging layer.
Improve the bearing capacity of formation，temperature：≤140℃."

PF-RG：Wellbore enhancement prevention technology
Overview：
PF-RG is a new graphite material with low density, high compression and recovery rate after pressure release. It has special
high elastic properties. When the downhole pressure increases, the product is compressed and deformed into the formation fracture. When the pressure is released, the material will return to its original shape, so as to enhance the stability of wellbore and plug the formation fracture.
Characteristics：
High pressure compressibility；High resilience；Increase formation pressure-bearing capacity.
Increase weak formation pressure-bearing capacity，temperature：≤230℃"

PF-STRH：Pressure Bearing Agent While Drilling
Overview：
PF-STRH is designed as fracture sealing and wellbore strengthening materials for fractured formations while drilling with
water-based drilling fluids. It can effectively reduce the potential for differential sticking and lost circulation through sealing problem zones.
Characteristics：
Effective sealing leakage formation；Improve the bearing capacity of formation; Good compatibility with drilling fluids.
Increase fracture pressure，Temperature：≤200℃"

PF-MOSTRH：Pressure Bearing Agent While Drilling For Non-aqueous Drilling Fluids
Overview：
PF-MOSTRH is designed as fracture sealing and wellbore strengthening materials for fractured formations while drilling with non-aqueous drilling fluids. It can effectively reduce the potential for differential sticking and lost circulation through sealing problem zones.
Characteristics：
Effective sealing leakage formation；Improve the bearing capacity of
formation;Good compatibility with drilling fluids.
