... attenuations of these two clays are quite different, with that of the bentonite increasing at about 4 times the rate of the attapulgite suspensions. Microwave attenuation measured for a variety of commercial drilling fluids varies over a wide range, with the lignosulfonates the largest (91 dB/m) and oil...

Such anionic polyelectrolytes are lignosulfonate complexes with various types of metals, tannins, humic acids, lignites and synthetic polymers (Zhang & Yin, 2002 ; Luo et al. , 2018 ).

The hydraulic pressure due to the swelling caused by water easily breaks the bonds of these binders. For this reason...
