Where λ & y are individual coefficients, the no. of equations = no. of coefficients - 1 Note in order to work there must exist 1 equation where all instances of λ and y != 0 ...

Conventional log analysis uses a sequential process to build up a petrophysical model of the formation. For example, we can use the GR to estimate shale volume, then use the density log with the shale ...

Simultaneous linear equations are used to model situations where two relationships must be satisfied at the same time. These problems often involve two interdependent variables, such as comparing ...
