according to Hall’s formula, a rock of 10% porosity has compressibility of 4.87×10-5 1/psi, and Horne’s correlation gives 8.43×10-6 1/psi, while the formation water has an approximate compressibility of (2.76–3.45)×10-5 1/psi. Hall’s plot gives the same value of compressibility for rocks of different lithol- Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or . This paper has proposed a new perspective of studying internal structure-based tests, the results of which will improve the present experimental methods and enrich our understanding of rock structure-based modeling without any core preparations, with low cost in a short time.

The overall pressure at any formation depth, as a result of the weight of fluid-saturated rock column, is known as overburden pressure, P ov.The whole pressure at any reservoir depth is the total of the fluid column pressure, P f, and the overlaying grain column pressure.P m, as seen in Fig. 7.1 and Eq. ():
Rock compressibility is required for different engineering applications in petroleum engineering including material balance calculations, reservoir simulation, and well test analysis. The isothermal compressibility is defined as the reduction in volume per unit of volume with a unit change in reservoir pressure, expressed as C. Mathematically .
