Description
Oyster-Shell F/M/C is a drilling fluid which is mostly composed of CaCO3. Oyster-Shell F/M/C are used in drilling fluid industry as loss circulation material which can be used in productive formations due to its high solubility in HCl acid. Oyster-Shell is available in three size grades (fine, medium and coarse) and can be applied in different types of drilling fluids.
Advantages
- Effective LCM material
- Can be applied as a mixture with other types of LCMs such asCALCIUM CARBONATE F/M/C
- Applicable in fractured and vugular loss zones
- Environmentally benign.
- Compatible with both water-based and oil-based mud systems
- High acid solubility
- Wide particle size for optimizing the fractures with different widths
- Compatible with all salts
- Applicable in different range of pH (7 to 11)
Applications
- Lost Circulation Material in Oil-based and Water-based muds
- Applicable in thief zones to minimize downhole loss
- Suitable for both reservoir and non-reservoir formation
