Ground marble bridging agent
High-purity, acid-soluble calcium carbonate used as a bridging and weighting agent in drilling, drill-in, workover, and completion fluids.
G-SEAL PLUS and G-SEAL PLUS COARSE wellbore stabilizing agents bridge and seal porous and fractured formations in water-, oil-, and synthetic-based drilling fluid systems.
When used to drill depleted zones with high differential pressures, the products' bridging and plugging capabilities reduce differential-pressure sticking tendencies. Both products can control seepage, decrease partial and severe lost circulation, and reduce torque and drag. G-SEAL PLUS and G-SEAL PLUS COARSE agents are chemically inert and will not affect the rheological properties of drilling fluid systems when used at the recommended concentrations.
Both agents can also be used dry-blended with cement to effectively seal off induced fractures and inhibit further propagation while cementing casing. Torque and drag may be reduced by incorporating sweeps of G-SEAL PLUS or G-SEAL PLUS COARSE agents into the active system up to a total concentration of 20 lbm/bbl [57 kg/m3]. Initial treatments for the active system may be added in 4-lbm/bbl [11.4-kg/m3] increments while monitoring torque and drag.
G-SEAL PLUS and G-SEAL PLUS COARSE agents may require additional wetting agent when used in an oil- or synthetic-based drilling fluid system.
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.
G-SEAL PLUS and G-SEAL PLUS COARSE agents are packaged in 25-lbm [11.3 kg] multiwall paper sacks. Store in dry, well-ventilated area. Keep container closed. Store away from
incompatibles. Follow safe warehousing practices regarding palletizing, banding,
shrink-wrapping, and stacking.
Serve as effective bridging and sealing agents for a wide range of formations.
Water-base mud with KLA-STOP and POROSEAL additives delivers high drilling performance while meeting environmental regulations.
Wellbore stabilizing agent helps decrease rig time, prevent fluid invasion, and improve wellbore stability in appraisal and development wells.
All offset wells drilled in this area of the Taranaki basin had experienced problems coming out of the hole after trouble-free drilling of the 12¼-in. section.
Minimized mud losses substantially while drilling the interval compared with the offset wells.
