These properties of rocks from the Kola well were measured on core samples only and then used mainly in solving various drilling technology problems. The parameters that had to be determined are as follows: static Young’s modulus E st ; static Poisson ratio v st ; compressive strength G c ; tensile strength G t ; indentation hardness P i ; plasticity K pl ; and abrasivity z.
