Losseal Reinforced Composite Mat Pills Family

Overview Library

Mitigate the risk of lost circulation while drilling

The Losseal reinforced composite mat pills family uses an innovative blend of fibers and sized solids to bridge and plug thief zones that can lead to lost circulation while drilling and cementing. Treatment using the Losseal family meets the demands of a wide range of environments including natural fractures, dolomite and carbonate zones, rubble zones, depleted reservoirs, and reservoirs with known lost circulation issues.The reinforced composite mat pills can be pumped through BHA nozzles as small as 8/32 in—eliminating the need to pull out of hole.

Create an impermeable grid against losses

The Losseal reinforced composite mat pills family creates a strong, impermeable grid that stops fluids from flowing into high-conductive zones. The grid is designed to withstand additional pressure from wellbore dynamic pressures and fluid density increases, and any future drilling or cementing operations. Treatment using these reinforced composite mat pills saves thousands of barrels of fluid during circulation or placements and reduces NPT caused by lost circulation.

Seal off thief zones without detailed measurements

Traditional lost circulation materials are often successful for a fixed pore or fracture opening. The Losseal family is much less sensitive to fracture sizes or variation in fracture sizes and can be applied without detailed formation measurements.

Losseal family treatment applications

  • Losseal Microfracture lost circulation control treatment is comprised of a composite blend of fibers and solids that create a strong matrix that stops mud or cement from flowing into microfractured zones.

  • Losseal Natural Fracture lost circulation control treatment is comprised of a composite blend of fibers and solids that create a strong impermeable grid, stopping mud or cement from flowing into natural fractured zones.

  • Losseal Reservoir Fracture lost circulation control treatment is comprised of a composite blend of dissolvable fibers and solids, providing a highly effective lost circulation solution during drilling. The pill used for the treatment is nondamaging to production, as it loses its mechanical properties over time, allowing the zone to produce without the need for remedial treatment.
