HL-BHY- Drilling In Fluids
Hilong drill-in fluid uses a bridging technique to positively control fluid leakoff into the formation. It also provides a filter cake that can be easily and effectively removed during production.
a.Provides effective leakoff control with customized bridging particles
b.Minimizes formation damage
c.Simplifies cleanup process
d.Operates effectively in a variety of coring applications and gravel-pack completions
e.Maximizes hydrocarbon recovery
Bridge Particles destribution:5% and 1/3 Rule
