OS G PLUG LPM - Graphite Loss Prevention Material for Drilling Mud

 

 

Loss Prevention Materials & Wellbore Strengthening

Effective wellbore strengthening requires that an adequate concentration of properly sized and shaped particles of sufficient physical strength are present in a mud as fractures are induced. The LPM can then pack the initial fracture and prevent further propagation and whole mud losses. The packed fracture then increases the hoop stress of the near wellbore and increases the apparent rock strength. OS G PLUG LPM is an ideal material for effective loss prevention.

 

Product Information 

OS G PLUG LPM is a specific sized processed graphite that is designed especially for use in drilling muds. The specific size distribution is critical in optimising effective wellbore strengthening. OS OS G PLUG LPM is chemically inert and it is temperature stable to greater than 250oC. Additions of OS G PLUG LPM will also reduce torque and drag and reduce the instance of differential sticking. OS G PLUG LPM is REACH compliant and is a PLONOR product. OS G PLUG LPM is E.U. origin.
