... of these cementing fluids on steel can be quantified using solids-free fluids. Further, laboratory methods to expose the steel coupon to fluids under realistic shear, time interval, and temperature were developed. Various fluids were tested on metal coupons and measured for the contact angles after each treatment...

For CaseA, the initial contact pressure is low due to the zero effective stress in the cement sheath. Therefore the tensile stresses induced by the shrinkage of the casing alone...
