Which consequence results when high sustained shear forces disrupt thixotropic bonds in drilling mud?

A)Increased corrosion of drillstring components

B)Catastrophic loss of borehole pressure✓

C)Elevated methane hydrate formation rates

D)Reduced thermal gradient through ground

💡 Explanation

Depleted attractive forces cause the gel structure to break down exhibiting shearthinning, because this reduces viscosity, and therefore the hydrostatic borehole pressure decreases, leading to potential influx, rather than stabilised pressure.
