YOGI’S RM rheology modifier is solution of an alkyl ammonium salt of polycarboxylic acid.
YOGI’-RM for oil- and synthetic-base muds that provides high viscosity at low shear rates, which is useful when drilling high-angle and horizontal wells and can be critical for cuttings carrying and to prevent sag and settling of weighting material YOGI’S RM can be incorporated directly into the mud system. Minimal agitation is required.
0.25-2.0 lb/bbl (0.7-5.5 kg/m3) is recommended additions for most formulations and drilling conditions. Temperature stable to 177 °C (350 °F)
