Losseal Max
Lost circulation control treatment
Lost circulation control treatment to bridge and plug large fractures to reduce fluids lost to the formation.
Losseal Natural Fracture
Lost circulation control treatment
Overview
Bridge fractures with pressure-resistant seal
The Losseal Natural Fracture™ lost circulation control treatment combines engineered fibers and solids into a specially formulated pill that effectively mitigates lost circulation during drilling. The Losseal treatment leverages the synergy between fiber and solid properties to bridge fractures that could cause partial or total fluid losses. This treatment forms a strong, impermeable grid capable of withstanding increased mud density and pressure from future drilling or cementing operations.
Applications
- Losses while drilling
- Fluid losses greater than 40 bbl/h
- Natural fractures
- Dolomite and limestone zones
- Spacers ahead of cement slurries
Benefits
Reduces flat drilling time
Extends well life
Reduces volume of lost mud and slurry, saving costs
Features
- High-differential-pressure resistance
- Reduced losses in fissures and natural fractures
- No requirement for laboratory tests
- Combination of fiber bridging and solids plugging for durable fracture plugging
- Can be pumped through most BHAs during LWD and MWD, eliminating unnecessary, time-consuming trips
The Losseal Natural Fracture treatment creates an impermeable seal to cure losses.
