Safe-Carb ground marble bridging agent is a high-purity, acid-soluble calcium carbonate used as a bridging and weighting agent in drilling, drill-in, workover, and completion fluids. Compared with limestone, the agent features higher hardness and purity, providing better acid solubility.

This calcium carbonate bridging and weighting agent can be used in fluids ranging from conventional drilling fluids to advanced drill-in fluid systems, including FLOPRO NT* water-based reservoir drill-in fluid, FAZEPRO* reversible invert-emulsion reservoir drill-in fluid system, VERSAPRO* invert-emulsion reservoir drill-in fluid system, and DIPRO* high-density divalent reservoir drill-in fluid.

It can also be used with SEAL-N-PEEL* fluid loss control pill to seal the inside of sand-control completion assemblies as a bridging agent and fluid-loss additive. Use OPTIBRIDGE software to select the optimal blend of SAFE-CARB agent to reduce fluid loss and minimize fluid and solids invasion.
