Figure

Figure 1: A fluid-filled borehole in a radially layered formation. An elastic wave impinges on the cased and cemented borehole with an angle of incidence 0 (with respect to the borehole axis)
Figure 4: Effective moduli of a cased borehole as a function of casing thickness. The formation is Berea sandstone (hard).
Figure 5: Effective moduli of a cased borehole as a function of casing thickness. The formation is Pierre shale (soft).
Figure 6: Effective moduli of a cased borehole as a function of formation rigidity.
