then correlated with a “surface” node in the model. The horizontal displacements
of the line of vertical nodes were assumed to represent the deformations of a
well. As an example, well deformations for the nodes corresponding to the
location of well 551G in Section 33 are shown in Figure 11.13. This well was
located near the northern edge of the Section 33 cross-sectional model, in an area
where shear deformations were significant. The plotted deformations show that
the well was dragged laterally toward the center of the subsidence bowl about 40
