SURE-SEAL™ LPM is a proprietary natural Loss Prevention Material (LPM) for use in wellbore strengthening procedures. SURE-SEAL™ LPM significantly increases near well bore formation fracture resistance by inhibiting the initiation and propagation of fractures before loss circulation begins. LPM’s have shown in field applications to increase fracture resistance by 3-6 ppg and more. SURE-SEAL™ LPM is a highly durable additive that has minimal impact on fluid density or rheology even at concentrations of 50 ppb.


  • Product is all natural and therefore biodegradable
  • Product is a high strength material with a compressive strength of >8000 psi
  • Product is a resilient material with an Elastic Modulus of 965 kpsi and a resiliency of 20.0%
  • Works in drilling fluids of any pH
  • Acid solubility in 15% HCl at 150 °F is 41.76% after a 16 hr. soak
  • Product is a low crush material and is less brittle than many other LCM’s such as calcium carbonate
  • Product is granular and packs tighter than fibrous shaped LCM such as cedar fiber or mica
  • Product is slightly deformable but not too deformable such that it forms a better seal and has a lower fracture conductivity value than other deformable materials
  • Product maybe used in high concentrations with minimal impact on fluid density
  • Product has minimal effects on rheology compared to other LCM’s such as cedar fiber and cotton seed hulls
