Bore-Seal 100

Preeminent Wellbore Strengthening Product

Product Summary

Bore-Seal 100 is a wellbore stabilizer that creates a fast-effective seal to minimize fluid and
pressure invasion into the formation. This product effectively seals a wide range of fracture
sizes and creates a barrier that allows for overbalanced drilling to continue. It is particularly useful as a “back ground” to ensure low fluid invasion across many reservoir types.

Wellbore Stability Benefits

  • When Bore-Seal 100 is pumped, a “stress cage” effect is developed and any differential pressure load is transferred over the wall cake on the wellbore, rather than the pressure load bearing down on
    the fracture point itself, decreasing the probability of propagation and worsening losses.

  • Diminishes the risk of differential sticking in highly permeable formations and is thermally stable at elevated temperatures.

  • Bore-Seal 100 is equally effective in water base, oil base, synthetic base and salt/polymer mud systems.

  • Excels in depleted or poorly consolidated formations, interbedded formations and mechanically weak formations.

  • Excellent seepage and lost circulation control without damaging mud rheology
