The next step is to determine the effect of the observation error on the well path position. In this diagram (Figure 79) you can see that a measured depth error could affect North East and TVD.
Figure 79: Showing that a measured depth error could affect North, East and TVD.
But an azimuth error only affects North and East (Figure 80), so we get the following:
