It is a high purity ground marble. It is used as a bridging and weighting agent in drilling, work over and completion fluids.
CaCO3 powder / calcium carbonate (F, M, C)
1) Acid-soluble, high-purity product which minimizes formation damage.
2) High hardness, Calcium Carbonate resists particle-size degradation.
3) Essential inert, minimum effect on fluid properties.
4) It is preferred over limestone because it is generally more pure with a higher hardness and it provides better acid solubility.
Calcium Carbonate is an acid soluble additive used for bridging and weighting agent for a controlling fluid loss and density. As a bridging agent and fluid loss-additive, normal concentrations are in the 10 to 50lb/bbl range (29 to 143 kg/m3).
Calcium Carbonate can also be added on a periodic basis for seepage control to limit losses (lost circulation and leak-off) to high permeability formations. It is particularly effective when drilling with high differential pressures caused by an overbalanced condition or when drilling depleted zones. Treatments range from 2 to 10 sacks per hour when used a preventative measure.
For depleted zone drilling or induced fracture applications, Calcium Carbonate is most effective when used in combination with Graphite additive.
