Imaging the Morrow A Sandstone Using Shear Wave VSP Data, Postle Field, Oklahoma
Figure 8
(a) shows a shear wave VSP shot gather after reorienting receivers based on the compressional wave hodogram analysis of only the far-offset vertical source. (b) depicts the same shot gather after utilizing three methods (i.e., compressional wave hodogram analysis of the far-offset vertical source, compressional wave hodogram analysis of a few horizontal sources, and the 3C amplitude analysis). Utilizing three methods in the receiver reorientation process caused remarkable improvements (note the red boxes and circles).
