Figure below from Keary et. al. (2002) shows some modeled (calculated) data for two non- reservoir rocks: a sandstone and a limestone. Answer the following questions: Seismic P-wave velocity in m s¹ 6500 6000 5500 5000 4500 4000 3500 3000 2500 2000 1500 1000 1000 Density-Velocity Cross-plot --Sandstone Limestone 100% 1500 50% 2000 Density in kg m-³ 2500 0% Fig. 3.6 The relationship of seismic velocity and density to porosity, calculated for mono-mineralic granular solids: open circles-sandstone, calculated for a quartz matrix; solid circles -- limestone, calculated for a calcite matrix. 3000 (a) Each rock type consists of two components. What are they for each rock? (b) For all of the components involved in the two rock types, estimate their densities and P-wave velocities from the graph. (c) In the figure, a third property of each rock type can be indicated. What is it? (d) Is there any place in the figure where these three properties have the same value for the two rock types? Give details.
