Abstract
To ensure reliable core analysis results, in addition to the invasion-related core damage (discussed in Chap. 7), the least possible mechanical damage should occur to the core. Mechanical core damage is defined as a permanent change in rock properties which is not reversible by restoring the rock back to in situ conditions.

Hydraulic diffusivity (\( \eta \)) is found by: \( \eta = 9.869 \times 10^{ - 13} \frac{K}{{\varphi \mu C_{t} }}, \) where \( K \) is permeability (mD), \( \varphi \) is porosity, \( \mu \) is viscosity (cp); and \( C_{t} \) is the total compressibility (1/Pa).
