NaCl Polymer CaCO3 Mud
Reservoir sections can be drilled with a low colloidal content sodium chloride/polymer mud system weighted with calcium carbonate. The recommended formulation is to minimise formation in a sandstone reservoir.
CACO3 Acid soluble weighting agent.
SODIUM CHLORIDE To improve shale inhibition.
IDVIS A pure grade xanthan gum, for providing yield point and progressive gel strengths.
FLOPLEX Fluid loss reducing polymer.
GLUTERALDEHYDE Environmentally acceptable biocide.
LIME pH control together with soda ash as well as to control soluble carbonate and bicarbonate concentrations . . .
