MEX-CARB

DESCRIPTION

MEX-CARB is fractionated acid-soluble micro marble. This additive is a weighting agent and sealant used to treat mud systems, primary drilling fluids and completion/ workover fluids.

MAIN PHYSICAL PROPERTIES

Appearance:                                                        white powder

Density:                                                             2,7 – 2,8 g/cm3

Solubility in a 15% sulphuric acid at 25оС:                      ≥98%

PRODUCT USE:

MEX-CARB is used as a weight material and sealant. Fractionated calcium coronate allows to optimize the granulometric content of drilling solids in the mud systems with respect to the actual properties of the production intervals or fluid-loss intervals.

MEX-CARB is produced in  three grain size fractions - FINE, MEDIUM and COARSE.

It is recommended to maintain a minimal concentration of MEX-CARB in the amount of 3% of the volume (80 kg/m3) and higher, to form a good quality filter cake.

      ADVANTAGES:

      LIMITATIONS:

  • Acid-soluble additive that prevents contamination of the production formation.
  • Effective sealant.
  • Special sort of micro marble prevents it rapid wear in the mud system.
  • It is chemically inert and it does not affect the properties of the drilling fluid.
    • It does not wear drilling equipment.
  • If used in primary drilling fluids, it is recommended to select the size of the particles based on the pore sizes and/ or permeability of the pay zone.
 

PACKAGING AND HANDLING

MEX-CARB is packaged in 30 kg or 40 kg multilayer paper bags. Use conventional PPE when handling the product (safety goggles, gloves and dust mask. Handle as recommended in the MSDS.
