Sized Graphite Supplier and Manufacturer

Sized Graphite

Sized graphite are resilient, angular, dual-carbon based lost circulation materials. These unique resilient graphitic carbon (RGC) products allow tightly packed particles, under compression in pores and micro fractures, to compress and then expand without being dislodged by changes in differential pressure. The range in particle size allows graphite lost circulation material to act as bridging and sealing agents over a wide range of pore and fracture sizes where other materials might fail. Sized graphite lost circulation material is manufactured in four particle size ranges as graphite 50, 100, 400 and 1000 lost circulation materials with the numbers indicating the approximate median particle size. Their unique physical character permits concentrations as high as 100 lb/bbl and does not adversely affect fluid rheology. Combined with CaCO3 modeling technology, graphite lost circulation material can be used to increase well-bore strength. The manufacture of RGC materials is patent protected by the supplier with exclusive sales to the petroleum industry by UNIVERSAL

APPLICATIONS


Helps seal porous and fractured formations
Helps impart lubricity to water-based fluids
Helps reduce torque and drag


ADVANTAGES


Designed for loss circulation prevention in synthetic and water-based drilling fluids.
Increased fracture propagation pressures of test samples exposed to oil-based and synthetic- based fluids.
Exhibits a resiliency that allows it to deform to fracture size.
Concentrations up to 100 lb/bbl (300 kg/m³) have been added without plugging drilling equipment or adversely affecting rheological properties.


LIMITATIONS


    As a background concentration for seepage and lost circulation control, 15-25 lb/bbl (40-70 kg/m³)
    LCM pill for spotting over thief zones or on bottom prior to trips, 50-100 lb/bbl (140-300 kg/m³)
    For lubricity in water-based fluids, 3-10 lb/bbl (10-30 kg/m³)

TOXICITY AND HANDLING


Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described in the Material Safety Data Sheet (MSDS).
