G-SEAL HRG FINE is a high resiliency graphite that provides enhanced bridging and sealing of mobile fractures. G-SEAL HRG FINE additive can be used in conjunction with or as a replacement for G-SEAL HRG high resiliency graphite or G-SEAL. It is compatible with water-, oil- or synthetic-base mud systems and is an effective bridging and sealing material for natural or induced fractures and for drilling permeable formations. The bridging ability of G-SEAL HRG Fine additive makes it an effective additive for drilling depleted zones where high differential pressures increase sticking tendencies. It can be used to control seepage in partial-to- severe lost-circulation zones. G-SEAL HRG Fine additive is completely inert and does not affect rheological properties. It reduces torque and drag by increasing the lubricity. In addition, G-SEAL HRG FINE additive lowers the spurt and total filtrate loss values in Permeability Plugging Apparatus (PPA) testing.
